Acute ruptured appendicitis and peritonitis with pseudomyocardial infarction.

Acute abdominal conditions unexpectedly present with electrocardiographic changes. However, the presence of electrocardiographic changes and misleading clinical manifestations may obscure true etiology and delay surgical interventions. We present a patient who developed ruptured appendicitis with peritonitis manifested as acute inferior wall myocardial infarction-like electrocardiographic changes. A thorough physical examination and early echocardiographic evaluation helped to differentiate this pseudomyocardial infarction. A 64-multidetector-row computed tomography of the abdomen showed ruptured retrocecal appendicitis, and emergent appendectomy was done. Normalization of ST segments was observed after surgery.
