A 3-year-old NM DSH was presented for evaluation of vomiting and diarrhea. Radiographs showed constipation and narrowing of caudal colon by a dorsal mass effect compressing the colon. On rectal exam a large smooth firm mass was present.
Case Study
04_00419 Willy F Pelvic mass
Sonographic Differential Diagnosis
Descending colonic or pelvic lymph node mass. This appears isolated and potentially resectable. There is a potential for granuloma, carcinoma or lymphoma. Ultrasound-guided FNA are recommended for definition followed by potential surgical, oncological or radiation treatment. Resection may be possible; however, splitting the pelvic bone would be necessary.
Image Interpretation
An irregular pelvic mass was noted and impinged the descending colon. The mass may be deriving from the descending colonic wall. The mass was echogenic and moderately complex measuring 5.23 x 3.1 cm. This mass appeared to be isolated.
