This FS 16-year-old DSH presented for anorexia, weight loss and PU/PD. Physical exam revealed a poor body condition, small irregular kidneys and a palpable intestinal thickening. Blood analysis demonstrated moderately elevated BUN and moderately elevated creatinine with a mild amylase elevation. Urinalysis demonstrated evidence of urinary tract infection and isosthenuria. Radiographs demonstrated a mid abdominal density with intestinal displacement.

Case Study
Intestinal Lymphocytic Lymphoma in a 16 year old FS DSH cat
Sonographic Differential Diagnosis
Small bowel mural mass compatible with neoplasia such as lymphosarcoma or adenocarcinoma, possible leiomyoma or leiomyosarcoma.
Image Interpretation
The transverse image of a segment of small bowel demonstrates marked, asymmetrical mural thickening with complete loss of normal wall architecture. The peripheral serosal margin is slightly irregular; however, it appears to be intact.
DX
Intestinal lymphocytic lymphoma
Outcome
The patient responded briefly to aggressive antibiotic therapy with eventual prednisone and chlorambucil. The patient was euthanized after 2 months due to clinical decline.
Clinical Differential Diagnosis
GI pathology – Intestinal thickening differentials include gastroenteritis, IBD, neoplasia, granulomatous inflammation. Renal pathology – chronic renal failure
Sampling
22 ga US-guided FNA revealed lymphocytic lymphoma.
