Causes Of Hemorrhagic Cysts
A cyst is usually caused by the body not being able to correctly drain fluids from the tissue. What makes hemorrhagic cysts unique is that they are filled with blood. If a hemorrhagic cyst should grow and rupture, the individual would experience active internal bleeding. This may last for a short amount of time until the body repairs itself or become a greater problem needing emergency intervention. This usually occurs in vascular tissues such as the ovaries.
Hemorrhagic ovarian cysts are some of the most common types of hemorrhagic cysts that are found in clinical practice. These types of cysts occur in women who still experience menstruation. Every month when an egg is released, it travels through the ovarian follicle and sometimes causes this follicle to bleed and forms a cyst.
While they may be painful, hemorrhagic ovarian cysts typically do not have many other symptoms that accompany them. Fertility is not affected unless the cysts become so common and large, around 10 cm, that the ovaries need to be removed.
Hemorrhagic cysts that occur elsewhere in the body can be caused by infection, chronic irritation of tissues or chronic inflammation.
Cysts In Kidney: When To Be Concerned
Many people with simple kidney cysts are asked to have a watchful waiting procedure. In other words, they are usually suggested to periodically take an imaging test to see whether the cysts are still tolerated or the treatment should be taken promptly.
While most of the time cysts in the kidneys are considered harmless and dont require treatment, this could be different when they have caused symptoms and complications.
Although these cysts are usually not serious or even sometime they may go away naturally without treatment, its not always easy to stop worrying about them. In general, the treatment may be suggested if some of the following conditions occur:
Causes Of Complex Kidney Cysts
A complex kidney cyst can develop as a secondary manifestation of a simple cyst. Such relapse occurs as a result of complications such as infection or bleeding, and also as a result of the proliferative process .
As is the case with simple kidney cyst formation, different types of complex kidney cyst can give similar pictures on medical ultrasound diagnosis. Therefore, it is not possible to make an accurate diagnosis without additional examinations.
However, the timely detection of a complex kidney cyst with using ultrasound is already important in the successful treatment. Features indicating the presence of cystic formation during ultrasound diagnostics:
thickening and irregular contour of the cyst wall
presence of partitions
the presence of seals or solid elements in the tissues present in the plural
distinct vascularization .

About Polycystic Kidney Disease
Polycystic kidney disease inherited condition in which too many cysts develop and grow primarily within the kidney is different from simple kidney cysts.
In PKD, the cysts may also develop in other parts /organs of the body such as colon, spleen, pancreas, liver, and ovaries. Typically, it requires intensive treatment and monitoring. Although there is still no cure, some treatments are available to help control the symptoms and prevent the complications of the condition.
The most common problem associated with PKD is high blood pressure, which is also the starting point for other problems to occur. Other complications of the condition include:
Ct Or Mri: Advantages And Disadvantages
Contrast-enhanced CT is the modality of choice in evaluating cystic renal masses. Narrow detector thickness and intravenous administration of contrast agent are mandatory to detect thin septa and small enhancing nodules . Also, demonstration of enhancing areas helps differentiate solid components from hemorrhage or debris . MRI is used when CT is contraindicated or as a problem-solving modality for equivocal findings. Indeed, MRI can show some septa that are less apparent at CT and demonstrate definitive enhancement in those cysts that show only equivocal enhancement at CT . As a consequence, renal cysts can be placed in a higher Bosniak category with MRI than with CT .

Localized Cystic Renal Disease
Localized cystic renal disease is a rare, nonhereditary, form of cystic renal disease, which manifests as a conglomeration of multiple simple cysts of variable size . In contrast to ACKD and ADPKD, localized cystic renal disease is typically unilateral and not progressive. The disease usually involves only a portion of the kidney with a polar predilection . Entire renal involvement is rare . The contralateral kidney is normal. The presence of interposed normal renal parenchyma and the absence of a capsule help to differentiate localized cystic renal disease from cystic nephroma and multiloculated cystic RCC . Cystic involvement of other organs is typically absent .

Size Of Hemorrhagic Cysts
The size of a hemorrhagic cyst often depends on the location. Cysts that form on the vocal cords may be a significantly different size than a cyst that has formed in the liver. Because of this, a physician may base his treatment options on the size of the cyst relative to the area. Ovarian Cysts that are smaller than 5 cm are typically seen as cysts that may end up resolving themselves. However, hemorrhagic cysts of any size that begin to cause a lot of problems such as pain or interrupt other functions of the body are taken serious and surgical interventions may be warranted.
One of the largest hemorrhagic cysts that have been reported was that of an adrenal cyst on a 66-year-old male patient. The individuals complaint was swelling and pain in his abdomen. After diagnostic tests, the patient was found to have a 22 cm hemorrhagic cyst on an adrenal gland.
It is important to realize that sometimes cysts happen. Typically smaller cysts can be normal and may not present any problems at all and usually take care of themselves.

Dangers Of Hemorrhagic Kidney Cysts
2014-08-22 00:53
Renal cysts, which are commonly known as kidney cysts, are sacs that develop within or on the surface of kidneys. A hemorrhagic renal cyst is characterized by hemorrhage or bleeding into the cyst. This article is mainly about the dangers of hemorrhagic kidney cysts and will also provide you with some suggestions to help you get rid of this problem.
Why does kidney cysts bleed?
Like other tissues, kidney cyst has its own blood vessels on the wall. When it grows to a certain size , it starts to compress the nearby organs and even other cysts. With the enlargement of the cyst, its blood vessels may burst because of unbearable pressure from the oppression. Thats why you are diagnosed with hemorrhagic kidney cysts.
What are the dangers of hemorrhagic kidney cysts?
1. Blood in urine
2. Infection
3. Severe and persistent pain in the back, flank or abdomen
4. Fever
5. Sepsis
How to treat hemorrhagic kidney cysts?
1. Medicines: In general, antibiotics are prescribed to manage various infections. Besides, if you cannot bear the pain, painkillers are also required. You doctor may also recommend you diuretics to promote the discharge of wastes by increasing urine output. However, some of the medicines produce wastes that are excreted by the kidneys, which will burden then kidneys. If so, your kidneys will be further damaged. Your doctor know how should you be treated, while if not, you can consult our doctor online.
Do Kidney Cysts Need Surgery
The answer is no. As long as they are small in size and do not cause symptoms or complaints, cysts usually do not need surgery or treatment. However, the doctor will still advise the patient to undergo regular examinations to monitor the condition of the cyst.
Kidney cyst removal surgery usually only needs to be done if it has caused severe complaints or interfered with the functioning of the bodys organs. The doctor will determine whether or not the surgery is necessary taking into account the type, size, and growing location of the cyst, as well as whether the cyst is infected or not.
Therefore, you are advised to check with your doctor if you notice a lump in the body that may be a cyst, especially if the lump causes pain or other complaints. Thus, treatment can be given immediately if necessary and the danger of cyst disease can be avoided.
On the one hand, this therapy can help remove sac fluid out of the body through increased permeability of cystic walls and removing sac fluid out of the body through the circulatory system. On the other hand, this Osmotherapy can prevent the recurrence of kidney cysts and protect kidney function.

How Are Simple Kidney Cysts Diagnosed
Simple kidney cysts are often found while the patient is seeing the doctor about another condition. The most common tests used to diagnose simple kidney cysts include:
- Ultrasound: High-frequency soundwaves and echoes create images of the inside of the body.
- Computed tomography : X-rays and computers produce images of a cross-section of the body.· The scans require an injection of iodinated contrast n order to distinguish fluid-only filled cysts from solid masses.
- Magnetic resonance imaging : Magnets, radio waves and a computer create images of inside the body. They also can be used to tell the difference between cysts filled with fluid and solid masses. Because they don’t require iodinated contrast, MRIs are used for patients with iodine allergy.
What Is Polycystic Liver Disease
Polycystic liver disease is the development of multiple cysts in the liver. PLD cysts may cause pain, but they usually do not affect liver function. If PLD starts affecting liver function or becomes too painful, surgery may be needed. However, cysts can reoccur after surgery.
People with PLD are born with it, but usually do not have large cysts until they are adults. Polycystic liver disease is genetic. When it is found in one family member, all family members should be tested. PLD may be detected using an ultrasound or CT scan. It is more common in women than men.
Most people with PLD also have polycystic kidney disease , which are cysts in the kidneys that can cause high blood pressure and kidney failure. Sometimes a liver transplant and a kidney transplant may be necessary.

How Are Renal Cysts Treated
Renal cysts generally do not require treatment unless they are causing symptoms or harming kidney function. Treatment options include:
- Sclerotherapy: Also known as percutaneous alcohol ablation, sclerotherapy involves the insertion of a long needle through the skin and into the cyst under ultrasound guidance. The doctor will drain the cyst and fill it with an alcohol-based solution that causes the tissue to harden and shrink, reducing the chance of recurrence. The procedure is usually performed on an outpatient basis with a local anesthetic.
- Surgery: For larger cysts, a surgeon will make a small incision and access the cyst with a laparoscope. The surgeon will then drain the cyst and burn or cut away its outer layer. Laparoscopic surgery requires general anesthesia.
Mixed Epithelial And Stromal Tumors
The MESTs area heterogeneous group of rare renal tumors occurring predominantly in perimenopausal women . The MEST appears as a well-marginated lesion with a variable proportion of solid and cystic components . Septa and nodules can show heterogeneous and delayed enhancement . MEST can show an exophytic growth or herniate into the renal pelvis . Adult cystic nephroma is now classified within MEST family due to similar histologic and epidemiologic findings . This tumor appears as an encapsulated lesion, with cysts of variable size, and thin, variably enhancing, septa . Calcifications are peripheral and curvilinear . Solid components are typically absent . At MRI, the capsule and septa can show hypointensity on both T1- and T2-weighted images due to the fibrous composition. Since imaging features are non-specific, differentiation between MEST and cystic RCC requires pathologic examination.

What Happens If Kidney Cysts Are Not Treated Immediately
Cysts can form in one or both kidneys and on the inside or outside of the kidneys. Although generally benign, kidney cysts still have the potential to cause serious problems if they are large or if they have been left for too long without treatment.
Some dangers to be aware of if a kidney cyst is large or untreated is bleeding due to kidney rupture, swelling of the kidneys, as well as infection of the cyst. Untreated kidney cysts can also cause pain.
Bosniak Classification System For Renal Cysts
The most widely used system to classify cystic renal lesions was introduced by Bosniak in 1984 and revised in 1997 . This system was originally developed on CT findings, but it can be also used at MRI .
Renal cysts are divided into five categories on the basis of imaging appearance . Each Bosniak category reflects the likelihood of cystic RCC that ranges from I to IV . Category I, II, and, IIF cysts are nonsurgical, while categories III and IV are surgical.
Table 1 The five categories of renal cysts, divided on the basis of imaging appearanceFig. 2
Imaging features of cystic renal lesions according to Bosniak classification. a Bosniak category I cyst: thin wall. b Bosniak category II cyst: thin wall few, thin septa. c Bosniak category II-F cyst: minimally thickened wall several, minimally thickened septa. d Bosniak category III cyst: irregularly thickened wall several, irregularly thickened septa. e Bosniak category IV cyst: enhancing nodularity irregularly thickened wall several, irregularly thickened septa
In equivocal cases, another option is to use subtraction MRI to assess the presence or absence of enhancement .

Kidney Cyst Size Chart
A simple kidney cyst is a round sac of fluid that forms in the kidneys or in the kidneys. Kidneys are two organs in the form of nuts, serve to make urine and filter waste from the blood. You can study kidney cyst size chart| What Size Kidney Cyst is Considered Large?
There are four types of kidney cysts and the most common types are called non-cancerous cysts or simple kidney cysts. Simple kidney cysts rarely cause complications or kidney failure.
What Are The Symptoms Of Simple Kidney Cysts
Simple kidney cysts usually don’t cause any symptoms. In fact, most people who have them don’t know they have them. The cysts become a problem if they rupture and start to bleed, become infected, or grow so large that they push against other organs within the abdomen.
When simple kidney cysts do cause symptoms, they might include:
- Pain in the side between the ribs and hip, stomach or back.
Depending on where the cyst is located, it can affect how the kidney works. It can also lead to a type of high blood pressure if the cyst prevents the kidney from filtering extra fluid from the blood.

Is Nephrectomy Indicated In Adpkd
Indications for nephrectomy in patients with ADPKD include recurrent and/or severe infection, severe renal hemorrhage, intractable pain, and renal carcinoma. Pretransplant nephrectomy is not usually performed, to avoid the anephric state. Pretransplant nephrectomy should be considered only if an ADPKD kidney is sufficiently enlarged to interfere with the site of implantation of the donor kidney in the event of frequent, recurrent infection or hemorrhage in the native kidneys or when solid tumor cannot be ruled out. Hand-assisted laparoscopic nephrectomy is a feasible and safe procedure compared with open nephrectomy, which is associated with significant morbidity and mortality.

Kidney Cysts Topic Overview
They could be associated with some disorders that eventually impair the function of the kidneys. But again more commonly, they are a type called simple kidney cysts that rarely cause serious complications. And this type is what were talking about in this section.
Causes
Its not fully known yet what causes these cysts. Currently, research suggests that they develop when the kidneys surface layer weakens and forms diverticulum which then fills with fluid, disengages, and develops into a cyst.
As noted before, age is often to blame the risk of having the condition increases with age. Furthermore, gender may also have an effect. Its relatively more common in men than in women.
Symptoms
The cyst looks like an oval or round fluid-filled pouch that typically has a well-defined outline. It usually develops in the surface of the kidney. However sometime it may also form inside the kidney.

Most of the time, kidney cysts dont cause any symptoms. However, this doesnt mean that you can ignore them. Its still important to keep monitoring them!
How is kidney cyst diagnosed?
It is rarely to be concerned, and even it is often accidentally diagnosed. Many times it is discovered through an imaging test for another condition.
Standard procedures and tests to diagnose cysts in the kidneys include:
