Abstract/OtherAbstract:
Spontaneous intracholecystic bleeding is very rare. We report herein a very rare case of a pseudoaneurysm of the cystic artery due to acute cholecystitis. A 58-year-old man presented at the emergency department complaining of colicky pain in the right upper quadrant. Dynamic magnetic resonance imaging demonstrated an early-enhanced pooling of contrast material (suggestive of a pseudoaneurysm of the cystic artery) inside the neck of the gallbladder. After the proximal control of the hepatic artery, the patient underwent a cholecystectomy and a ligation of the cystic artery. The resected specimen of the gallbladder showed evidence of a massive intracholecystic hematoma. Proximal to the impacted gallstone in the neck, a 2-cm diameter saccular-type pseudoaneurysm was identified. Although a pseudoaneurysm of the cystic artery is very rare, it should be included in the differential diagnosis of hemobilia. Once the pseudoaneurysm is confirmed, its embolization before a cholecystectomy (which can be attempted laparoscopically) may be useful to ensure the safety of the patient.
