A 61-year -old male presented with a five month history of atypical left lower quadrant abdominal discomfort. There was no relevant past medical history and routine laboratory tests and physical examination were unremarkable. Work up included an abdominal CT of the lower abdomen. It revealed a well-delineated left intrapelvic soft tissue mass with some low attenuation areas, indistinguishable of the left seminal vesicle (Fig. A). He subsequently underwent a MRI of the pelvis. Axial T2-weighted MRI (Fig. B) demonstrated a well encapsulated mass, indistinguishable of the left seminal vesicle and a normal appearance of the right seminal vesicle. Coronal T1-weighted MRI (Fig. C) with fat saturation after the injection of intravenous gadolinium revealed the avid contrast uptake of the lesion with a small non-enhancing cystic component. It also depicted the extrinsic compression of the mass on the sigmoid colon and rectum.
