40-year-old male with complex renal cyst on MRA. Evaluate the renal cyst. ABDOMEN:LIVER, BILIARY TRACT: There is a segment 7 intermediate T2 signal lesion measuring approximately 2.2 x 2.5 cm with avid arterial enhancement which persists; this lesion most compatible with FNH.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS:RIGHT KIDNEY:Right exophytic, well encapsulated lesion anteriorly (series 4, image 15) which demonstrates T1 and T2 heterogeneous signal with probable low level contrast enhancement. This lesion measures 2.7 x 2.3 cm. This is suspicious for renal cell carcinoma.Right inferior pole subcentimeter T2 hyperintense focus with thin septations which likely enhance (series 4, image 28).Right posterior T2 hyperintense focus with mildly enhancing thin septations (series 4, image 18), compatible with a complex cyst.Additional subcentimeter T2 hyperintense nonenhancing foci compatible with cysts.LEFT KIDNEY: Left mid pole T2 hyperintense subcentimeter focus with questionable enhancement (series 4, image 12). This lesion is too small to characterize.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Right renal exophytic lesion anteriorly suspicious for renal cell carcinoma. Differential considerations include papillary over chromophobe.2.There are 2 complex cysts on the right and one complex cyst on the left as detailed above. Attention on follow-up is recommended.3.Segment 7 hepatic FNH.
