Typhlitis: A Rare Appendicitis Mimic in a Young Healthy Female.

Typhlitis, also known as neutropenic enterocolitis, is a rare but serious condition characterized by inflammation of the cecum causing right lower quadrant (RLQ) pain and fever. It typically affects immunocompromised patients with neutropenia, hematologic malignancies, AIDS, or those on immunosuppressive therapy. This is an entity that should be considered in any differential for a patient with febrile RLQ pain, not just those with obvious immunosuppression.
