A serial microscopic examination for acid-fast bacilli AFB was negative, as were a test for adenosine deaminase and a peritoneal fluid culture. Simple and contrasted abdominal CAT scans showed a thickening of up to 4mm of the terminal ileum walls and the ascending part of the colon plus an inflammatory process in both the small and large intestine but no paraneoplastic retroperitoneal lesion see Figure 2.
