Pseudocysts are like cysts, but lack epithelial or endothelial cells. Initial management consists of general supportive care. Symptoms and complications caused by pseudocysts require surgery. Computed tomography (CT) scans are used for initial imaging of cysts, and endoscopic ultrasounds are used in differentiating between cysts and pseudocysts.
Simple renal cyst. A renal cyst is a fluid collection in or on the kidney. There are several types based on the Bosniak classification. The majority are benign, simple cysts that can be monitored and not intervened upon. However, some are cancerous or are suspicious for cancer and are commonly removed in a surgical procedure called nephrectomy.
Cysts cause posterior enhancement as a consequence of reduced attenuation of the ultrasound within the cyst fluid (Figure 5). The simple cyst is a benign lesion, which does not require further evaluation. [1] Complex cysts can have membranes dividing the fluid-filled center with internal echoes, calcifications or irregular thickened walls.
Marsupialization is the surgical technique of cutting a slit into an abscess or cyst and suturing the edges of the slit to form a continuous surface from the exterior surface to the interior surface of the cyst or abscess. Sutured in this fashion, the site remains open and can drain freely.
Ascites (/ ə ˈ s aɪ t i z /; [5] Greek: ἀσκός, romanized: askos, meaning "bag" or "sac" [6]) is the abnormal build-up of fluid in the abdomen. [1] Technically, it is more than 25 ml of fluid in the peritoneal cavity, although volumes greater than one liter may occur. [4]

Splenic infarction is a condition in which blood flow supply to the spleen is compromised, [1] leading to partial or complete infarction (tissue death due to oxygen shortage) in the organ. [2] Splenic infarction occurs when the splenic artery or one of its branches are occluded, for example by a blood clot .
Cystic kidney disease includes various conditions related to the formation of cysts in one or both kidneys. The most common subset is polycystic kidney disease (PKD), which is a genetic anomaly with two subsets, autosomal recessive polycystic kidney disease (ARPKD) and autosomal dominant polycystic kidney disease (ADPKD).
