Hemobilia in the setting of cystic artery pseudoaneurysm secondary to type I Mirizzi syndrome

Hemobilia is an uncommon diagnosis and is often not suspected in the absence of recent hepatobiliary intervention or trauma. Hemobilia in the setting of cystic artery pseudoaneurysm secondary to type I Mirizzi syndrome is a rare occurrence. We report the case of a 61-year-old male who presented with...

Sumario:Hemobilia is an uncommon diagnosis and is often not suspected in the absence of recent hepatobiliary intervention or trauma. Hemobilia in the setting of cystic artery pseudoaneurysm secondary to type I Mirizzi syndrome is a rare occurrence. We report the case of a 61-year-old male who presented with epigastric pain and vomiting. Blood tests demonstrated hyperbilirubinemia with elevated inflammatory markers. Magnetic resonance cholangiopancreatography revealed type I Mirizzi syndrome in the presence of a 21 mm cystic duct stone. During endoscopic retrograde cholangiopancreatography, hemobilia was identified. Subsequent triple phase computed tomography imaging identified a 12 mm cystic artery pseudoaneurysm. Angiography with successful coiling of the cystic artery was accomplished. Cholecystectomy was performed, confirming type I Mirizzi syndrome. This case demonstrates the importance of considering ruptured pseudoaneurysm in patients presenting with evidence of upper gastrointestinal bleeding in the setting of biliary stone disease. Transarterial embolization, followed by surgical management, is effective in both the diagnosis and management of ruptured cystic artery pseudoaneurysm with associated hemobilia.
