Primary Follicular Lymphoma in the Small Intestine

A woman between 60 and 70 years of age experienced nausea, vomiting, and epigastric pain radiating throughout the abdomen for several days. Physical examination revealed abdominal tenderness with epigastric prominence, without peritoneal irritation. Dynamic computed tomography (CT) showed dilatation of the small intestine and two points of bowel obstruction due to intestinal wall thickening (Figure 1A, arrow), increased mesenteric fatty tissue (Figure 1B), and enlarged mesenteric lymph nodes (Figure 1B, arrowhead).
