title: Ruptured phaeochromocytoma--a lesson in acute abdomen.
abstract: Phaeochromocytoma may present as acute abdomen. This report is of a patient with spontaneous rupture of phaeochromocytoma who presented with abdominal pain and a tender abdominal mass. Ruptured phaeochromocytoma is a rare surgical emergency, with only 30 cases reported in the literature. The classical clinical triad of signs is intense vasoconstriction, tachycardia, and labile blood pressure. Computed tomography scanning of the abdomen is the investigation of choice, and a high index of suspicion is the key to diagnosis. Prompt recognition, appropriate supportive measures, and early surgical intervention can improve the likelihood of survival.
