A renal cyst is a fluid collection ... a CT scan without intravenous contrast ... Hyperdense cysts must be exophytic with at least 75 percent of its wall outside the ...
Unspecific cortical lesion on CT scan is confirmed cystic and benign with contrast-enhanced renal ultrasonography. A CT scan is the first choice modality for workup of solid masses in the kidneys. Nevertheless, hemorrhagic cysts can resemble renal cell carcinomas on CT, but they are easily distinguished with Doppler ultrasonography (Doppler US ...
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 ...
CT scanning can perform a virtual colonoscopy with greater accuracy and less discomfort for the patient than a traditional colonoscopy. [143] [144] Virtual colonography is far more accurate than a barium enema for detection of tumors and uses a lower radiation dose. [145] CT is a moderate-to-high radiation diagnostic technique.

Metastatic renal cell carcinoma (mRCC) is the spread of the primary renal cell carcinoma from the kidney to other organs. Approximately 25–30% of people have this metastatic spread by the time they are diagnosed with renal cell carcinoma. [ 101 ]
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 ...
Polycystic kidney disease (PKD or PCKD, also known as polycystic kidney syndrome) is a genetic disorder [5] [6] in which the renal tubules become structurally abnormal, resulting in the development and growth of multiple cysts within the kidney. [7] These cysts may begin to develop in utero, in infancy, in childhood, or in adulthood. [8] Cysts ...
