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.
Renal cysts have been reported in more than 50% of patients over the age of 50. [2] Typically, cysts grow up to 2.88 mm annually and may cause related pain and/or hemorrhage. [2] Of the cystic kidney diseases, the most common is polycystic kidney disease with two sub-types: the less prevalent autosomal recessive and more prevalent autosomal ...
Masses are seen as a distortion of the normal renal architecture. Most renal masses are simple cortical renal cysts with a round appearance and a smooth thin capsule encompassing anechoic fluid. The incidence increases with age, as at least 50% of people above the age of 50 have a simple cyst in one of the kidneys.
The enlargement of the kidney can be related to the degree of cyst formation. The cysts which come from the Bowmans space can also cause the kidneys to appear asymmetrical or misshapen. Cysts can cause injury by destroying nearby renal tissue [10] Familial GCKD can have enlarged or normal size kidneys. [6]
These cysts become enlarged with the progression of aging causing renal failure. Cysts may also form in other organs including the liver, brain, and ovaries. Polycystic kidney disease is a genetic disease caused by mutations in the PKD1, PKD2, and PKHD1 genes. This disease affects about half a million people in the US.
Medullary cystic kidney disease (MCKD) is an autosomal dominant kidney disorder characterized by tubulointerstitial sclerosis leading to end-stage renal disease.Because the presence of cysts is neither an early nor a typical diagnostic feature of the disease, and because at least four different gene mutations may give rise to the condition, the name autosomal dominant tubulointerstitial kidney ...
The characteristic appearance of renal cell carcinoma (RCC) is a solid renal lesion which disturbs the renal contour. It will frequently have an irregular or lobulated margin and may be seen as a lump on the lower pelvic or abdomen region.
Renal cortical necrosis (RCN) is a rare cause of acute kidney failure. The condition is "usually caused by significantly diminished arterial perfusion of the kidneys due to spasms of the feeding arteries, microvascular injury, or disseminated intravascular coagulation " and is the pathological progression of acute tubular necrosis .
