What is multilocular cyst of kidney?
Multilocular renal cyst is a distinct renal tumor whose gross external appearance and absence of normal renal tissue within the septa of loculi distinguish it clearly from other renal cystic lesions. Interlocular septa may contain either (1) fibrous tissue alone or (2) embryonic tissue separating adjacent loculi.
What is a cystic mass in the kidney?

What is a multilocular cystic Nephroma?
Multilocular cystic nephroma (MLCN) is a benign mixed mesenchymal and epithelial neoplasm of the kidney . MLCN is classically described as a benign slow-growing renal tumor, and there are more than 200 cases reported in the literature.
What is serous cyst?
Serous cystadenomas are usually composed of unilocular (or at times multilocular) cysts filled with clear watery fluid. The cysts measure 10 cm in average diameter but may be extremely large. The lining of the cyst is flat or may contain small papillary projections.
What is a Multiloculated cystic mass?
Multilocular cystic nephroma is a benign mixed mesenchymal and epithelial neoplasm of the kidney and is classically described as a benign slow-growing renal tumor. Patients who have multilocular cystic nephroma present with palpable mass, abdominal pain, and hematuria, as in renal cell carcinoma.
Should I worry about a cyst on my kidney?
Simple kidney cysts are almost always harmless. They are called “simple” because there is very little chance they will develop into something more serious. However, some cysts do have thickened walls, may look irregular on X-rays, and could be associated with kidney cancers.
Is a complex cyst on kidney serious?
More complicated cysts (complex kidney cysts or complex renal cysts) can interfere with kidney function, or create other complications. Complex kidney cysts require close radiographic imaging (CT scan or MRI), or surgical removal since these cysts can be cancerous.
What is cystic RCC?
A distinct subset of RCC, described as “cystic RCC,” accounts for <5% of all renal cell carcinomas . The World Health Organization defines this as a “tumor composed of numerous cysts, the septa of which contain small groups of clear cells indistinguishable from grade I clear cell carcinoma” .
What is a Hypernephroma in medical terms?
(HY-per-neh-FROH-muh) The most common type of kidney cancer. It begins in the lining of the renal tubules in the kidney. The renal tubules filter the blood and produce urine. Also called renal cell adenocarcinoma, renal cell cancer, and renal cell carcinoma.

How are cystic renal masses classified in radiology?
In the menubar in the upper left, you will find interactive cases. The Bosniak classification was described in 1986. This classification helps the radiologist to categorize each cystic renal mass as “nonsurgical” (ie, benign in category 1 and 2) or as “surgical” (ie, requiring surgery in category 3 and 4).
What are the symptoms of localized cystic renal disease?
Patients with localized cystic renal disease may be asymptomatic. Common presenting symptoms include abdominal pain, a flank mass, hematuria, and hypertension. There is no impairment of renal function (28). At imaging, localized cystic renal disease manifests as a conglomeration of cysts in one kidney.
What are the most common cystic masses in adults?
