Overview

Typhlitis occurs in neutropenic patients undergoing treatment for a malignancy, most frequently patients with acute leukemia who are receiving chemotherapy. It has also been reported in patients with aplastic anemia, lymphoma, or acquired immunodeficiency syndrome and after kidney transplantation. Typhlitis is characterized by edema and inflammation of the cecum, the ascending colon, and sometimes the terminal ileum. The inflammation can be so severe that transmural necrosis, perforation, and death can result. The mechanism of the condition is not known, but it is probably due to a combination of ischemia, infection (especially with cytomegalovirus), mucosal hemorrhage, and perhaps neoplastic infiltration. Treatment consists of bowel rest, total parenteral nutrition, antibiotics, and aggressive fluid and electrolyte replacement.

CT

• Cecal distention and circumferential thickening of the cecal wall
• Inflammatory stranding of the adjacent mesenteric fat is a common finding.
• Detection of complications such as pneumatosis, pneumoperitoneum, and pericolic fluid collections is important because they indicate a need for urgent surgical management.
