Herein, we have reported a rare case of intracystic hemorrhage due to rupture of a right hepatic artery pseudoaneurysm in a 76-year-old female patient who underwent drainage and 3% polidocanol sclerotherapy for a symptomatic giant hepatic cyst. One month after sclerotherapy, the patient presented to the emergency room with acute and severe abdominal pain. Non-contrast T1-weighted magnetic resonance imaging findings showed high hepatic cyst fluid signal intensity and abdominal arteriography findings revealed a right hepatic artery pseudoaneurysm surrounding the hepatic cystic wall. Therefore, the patient was diagnosed with intracystic hemorrhage due to a ruptured pseudoaneurysm. Embolization, using a detachable coil, was successful. Interventional radiologists should be aware of potential vascular injuries during drainage and sclerotherapy for giant hepatic cysts.
在此，我们报告了一例罕见的病例，一名76岁女性患者因症状性巨大肝囊肿接受引流和3%聚多卡醇硬化治疗后，发生右肝动脉假性动脉瘤破裂导致囊内出血。硬化治疗一个月后，患者因急性剧烈腹痛前往急诊室。非增强T1加权磁共振成像结果显示肝囊肿液信号强度高，腹部动脉造影结果显示肝囊肿壁周围有右肝动脉假性动脉瘤。因此，该患者被诊断为假性动脉瘤破裂导致囊内出血。使用可脱卸线圈进行栓塞成功。介入放射科医生应意识到在巨大肝囊肿引流和硬化治疗过程中潜在的血管损伤。
