Obstructive colonic mass in a 6 year old MN DSH cat

Case Study

Obstructive colonic mass in a 6 year old MN DSH cat

This 6 year old MN DSH has been screaming and straining while defecating for 3 weeks. Painful on caudal abdominal palpation

This 6 year old MN DSH has been screaming and straining while defecating for 3 weeks. Painful on caudal abdominal palpation

Image Interpretation

The stomach appeared normal. The descending colon was infiltrated and thickened measuring nearly 1.0 cm in wall thickness. Ultrasound-guided FNA is recommended along with regional lymph node enlargement. The colonic pathology was stricturing and obstructive. Embedded stool was noted in the lumen prior to the mural stricture. The small intestine was otherwise unremarkable. The colonic lymph node was hypoechoic, enlarged with distorted architecture and distorted length to width ratio measuring 1.6 x 1.1 cm. Rounding was noted.

DX

Descending colonic infiltrate pattern entering into the pelvis

Outcome

This is not likely resectable owing to the caudal extension of the pathology.
Abnormal colon was noted throughout the images, at least 4.0 cm caudal to the
cystourethral junction. Chronic colitis, possible with colonic carcinoma, colonic lymphoma as well as colonic mast cell disease. Ultrasound-guided FNA of the affected portion of the wall and
regional lymph node would be recommended. Three view chest radiographs are also
warranted.
