70-year-old female with right adrenal gland lesion noted on recent CT. Thorax for further characterization. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in size, morphology, and signal characteristics. Signal artifact from prior cholecystectomy. No focal lesion is identified. No intrahepatic or extrahepatic biliary ductal dilatation.SPLEEN: No significant abnormality noted.PANCREAS: The spleen is normal in signal and morphology. No pancreatic ductal dilatation.ADRENAL GLANDS: There is subtle nodularity of the posterior limb of the right adrenal gland. This appears to have signal drop out on the out of phase images (series 10 images 89 and 90) compatible with an adrenal adenoma. There is no enhancement on the postcontrast images.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Within the right hemiabdomen there is a 3.0 x 2.2 x 2.7 cm nonenhancing cystic collection with high T2 and minimally bright T1 intrinsic signal. There is no enhancement on the postcontrast images. This is not significantly changed from the most recent CT scan, but is new compared to 9/20/2006. This is nonspecific but may represent a peritoneal inclusion cyst.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Findings compatible with a small right adrenal adenoma.2.Nonspecific cystic collection in the right hemiabdomen which is unchanged compared to 2/22/2016, but was not present on the previous CT scan from 9/20/2006. This may represent a peritoneal inclusion cyst, but follow-up imaging can be considered as clinically warranted.
