Acute Typhlitis in a Patient with Common Variable Immunodeficiency.

Typhlitis, or neutropenic enterocolitis is characterized by edema and inflammation of the cecum, ascending colon, and sometimes the terminal ileum. Incidence is anywhere from 3.5 to 5.3%. Resolution usually corresponds with return of neutrophil counts. Here we describe an immunocompromised individual with abdominal pain and diagnosed to have acute typhlitis.
