An 11-year-old SF DSH was presented for evaluation of poor appetite for a month, tenesmus, and mucous discharge from the rectum.
Case Study
04_00532 Maize C Colonic mass, stricture
DX
Colonic mass, stricture
Sonographic Differential Diagnosis
Colonic mass, likely sarcoma, possible adenocarcinoma. Ultrasound-guided FNA of the hypoechoic portion of the mass should be readily accessible with oncology consultation. Guarded to poor prognosis. This does not appear resectable unless the surgeon is prepared to split the pelvis as the mass extends into the pelvic inlet at least 4.0 cm past the cranial aspect of the pubic bone. Chemoreduction +/- surgical consultation would likely be the best option in this case.
Image Interpretation
The pelvis in this patient revealed a 4.42 x 3.6 cm mass. The mass deviated the colonic lumen. This appeared to be an annular lesion deriving from the colon and obstructing the stool passage. The remainder of the gastrointestinal tract was unremarkable.
Outcome
None
Clinical Differential Diagnosis
Colon – constipation, lymphoplasmacytic colitis, neoplasia, granulomatous colitis
