An eight-year-old male Siamese cat was presented with signs of mild an
orexia, slow weight loss, hair pulling with irregular areas of alopeci
a and occasional vomiting. Conservative antibiotic therapy provided on
ly a temporary resolution of clinical signs and blood analysis was equ
ivocal. Positive contrast radiographic markers (B.I.P.S.(1)) were used
to diagnose a partial obstruction within the small intestine. A lapar
otomy was performed, involving an enterectomy of an area of jejunum af
fected by a fibrous annular mass causing stucture of the intestine. Hi
stopathology indicated a malignant adenocarcinoma of the jejunum with
a grave prognosis.
