Presentación atípica como abdomen agudo de un aneurisma de arteria iliaca gigante imitando colescistitis y lesión renal: reporte de caso

Abstract

The common iliac artery aneurysm is relatively rare, has been observed in only 2-7% of all intra-abdominal aneurysms. It is a life-threatening condition when rupture and massive bleeding occur. We report the case of a 38-year-old patient who presented to the emergency room due to abdominal pain in the right hypochondrium, jaundice in the sclera, and a positive Murphy sign, compatible with acute cholecystitis. Computerized axial tomography was performed due to an insidious clinical picture that incidentally revealed a giant aneurysm (>10 cm) in the right common iliac artery and mural thrombus. An open emergency surgical procedure was performed due to the size of the aneurysm and infection by free fluid in the cavity and repair with autologous aorto-femoral graft with a good outcome for the patient. Giant AAIC with significant renal and hepatic involvement may present atypically in clinical practice and mimic other surgical pathologies. Common iliac artery aneurysm is a disease with high morbidity and mortality since it can threaten the patient's life when the aneurysm ruptures. It should be taken into account within the differential diagnoses when the clinical manifestations are insidious.
