Case Study
Rectal Sarcoma in an 8-year-old MN Golden Retriever dog
Sonographic Differential Diagnosis
Pelvic mass, likely lymph node or blood vessel derived sarcoma. Possible prostatic carcinoma, yet the position would suggest pelvic sarcoma. Stool obstruction.
Image Interpretation
Stool obstruction appeared to be present. The rectum in this patient was deviated at the at the level of the urethra owing to a 6 x 7 cm, mixed, hypoechoic mass. This appeared to be contiguous with the prostate or impinging upon the residual prostate. The mass was micronodular with a minor, pericapsular inflammatory pattern.
DX
Sarcoma
Outcome
The owner is not interested in treating at this time.
Comments
A stool softener would be recommended. Chemotherapeutic protocol should be based on the cytology findings. Thoracic radiographs revealed thoracic nodules. Exact organ or structure of origin is not known at this time. Guarded prognosis.
Clinical Differential Diagnosis
Prostatic pathology – neoplasia, abscess, cyst; Colon/rectum pathology – neoplasia, polyp; Urethra pathology – neoplasia, granuloma; Intra-pelvic pathology – neoplasia, abscess, granuloma, lymph node
Sampling
FNAs of mass were performed
