Abstract Introduction Mucosa associated lymphoid tissue MALT lymphoma is the third most common non-Hodgkin s lymphoma subtype. Clinical presentation is often insidious as a low-grade lesion and disease tends to remain localised for a long period of time. Ileal involvement is rare and presentation within an area of focal anti-mesenteric ileal wall dilation simulating a large diverticulum has not been reported. Case presentation A 59-year-old man of Caucasian origin presented to a general surgical outpatients clinic with an 18-month history of intermittent upper abdominal pain following meals. Following normal gastroscopy and abdominal ultrasound a focally dilated segment of ileum was seen on computed tomography and further clarified by barium investigation. Histology of this segment demonstrated MALT lymphoma of the small bowel. Conclusion A solitary focally dilated segment of ileal wall may be neoplastic in nature and surgical resection needs to be considered. Introduction Mucosa .
