Renal cysts result from genetic or nongenetic processes and occur in a variety of diseases in adults and children. The most common causes of radiologically evident renal cysts in adults are simple renal cysts, which will be discussed in this topic review.


Six cases of benign hemorrhagic renal cyst are presented. Although these masses resembled cysts on nephrotomography and arteriography, exclusion of malignant disease was difficult on cyst puncture and gross surgical inspection. The aspirated fluid contained degenerating hemorrhagic material in all cases, malignant cells in none, and fat in one.


Spontaneous nonfatal retroperitoneal cyst hemorrhage, as in our patient, is rare. Indeed, in one series reviewing the abdominal computed tomographic findings of 66 patients with ADPKD, only 2 patients (3%) had perinephric hematomas in the absence of recent trauma. 6. Management of cyst hemorrhage is primarily conservative.


Acquired cystic renal disease is common in this age group, and 50 percent of patients with this medical issue develop hemorrhagic cysts. Wikipedia adds that patients with compromised immune systems are at a greater risk and that hemorrhagic cysts may also develop in women's ovaries.

Most are asymptomatic, though a large cyst can cause discomfort and hypertension. A ruptured cysts may result in hematuria; an infected cyst results in fever. Both infected cysts and hemorrhagic cysts are non-simple by imaging (Bosniak II or greater). Ultrasound shows a sharp interface between cyst and adjacent renal parenchyma.
