Case Study

04_00502 Tiki F Colonic mass with stricture

A 15-year-old SF DSH with a history of diabetes mellitus and recent onset suspected spinal vascular accident was presented for evaluation of acute diarrhea, decreased appetite, and abdominal distension. The only abnormality on urinalysis was glycosuria.

 

Sonographic Differential Diagnosis

Stricturing colonic mass, obstructive pattern. Colic mesenteric lymphadenopathy with reactive fat. Trace amount of free fluid was noted adjacent to the colonic area. This is strongly consistent with a colonic carcinoma, possible lymphoma. Given the neurological issues metastatic disease should be a primary concern. CT with contrast of the CNS is recommended. Guarded to poor prognosis. Ultrasound-guided FNA of the mass could be considered for further definition to assess for potential chemoresponsiveness. Regional peritonitis was noted around the stricturing mass, possible perforation. Analysis of the free fluid is recommended.

Image Interpretation

The descending colon in this patient was significantly repleted. A stricturing colonic mass was noted and measured 2 x 4.0 cm. The mass was obstructive. Stool was impacted to the transverse colon. Peritonitis was noted around the stricturing mass. Regional lymphadenopathy was also noted and measured 1.5 x 1.0 cm each with reactive, hyperechoic ill defined fat. Mesenteric lymph nodes measured 1.55 cm and 0.95 cm with reactive surrounding fat.
