title: Spontaneous rupture of a vesicourachal diverticulum manifesting as acute abdominal pain.
abstract: Urachal abnormalities are rare clinical entities. This article reports a case of a spontaneously ruptured vesicourachal diverticulum manifesting as acute abdominal pain in a healthy 38-year-old man. The embryology, clinical diagnosis, and management of urachal abnormalities are discussed. Emergency physicians should include this clinical entity in their differential diagnoses of patients who develop acute abdominal pain in the absence of trauma, especially when the pain immediately follows a maneuver that increases intra-abdominal pressure.
