Male 73 years old Reason: rectal cancer staging History: As per chart, status post anterior resection for stage I rectosigmoid carcinoma in 2006, then with anastomotic recurrence and revision anterior resection and abdominoperineal resection in 2007. Overall image quality: FairPELVIS:PROSTATE/SEMINAL VESICLES: Numerous brachytherapy seeds are noted in the prostate.BLADDER: A pigtail catheter is noted extending from the right ureter, otherwise the bladder is unremarkable.LYMPH NODES: No significant lymphadenopathy noted.BOWEL, MESENTERY: Patient is status post sigmoidectomy.There are multiple heterogeneous, peripherally enhancing lesions in the pelvis (series 7, image 21 and 26; series 12, images 148 and 157). The largest of these lesions lies between the right iliac vessels and right ureter, displaces the ureter medially, and measures 68 x 55 mm. There is internal septation with heterogeneous, dependent low T2 signal within this lesion. A second lesion sits immediately anterior to the sacrum, superior to the seminal vesicles, and measures 32 x 29 mm. This lesion also contains heterogeneous T2 hypointense signal. There is no masslike or nodular enhancement within these lesions. Additional, smaller lobulated areas of T2 hyperintensity (series 5, image 25) are also noted in the left hemipelvis along the pelvic wall.BONES, SOFT TISSUES: Small bilateral hydroceles.OTHER: No significant abnormality noted.
Heterogeneous, peripherally enhancing complex cystic masses in the pelvis which are suspicious for disease recurrence, particularly of the mucinous subtype.
