Old hemorrhage with cystic degeneration of hepatic cavernous hemangioma: A case report

Abstract

Abstract Background:Hepatic cavernous hemangioma is the most common benign tumor of the liver, but spontaneous intratumoral hemorrhage of the tumor is clinically rare, and cystic degeneration caused by old hemorrhage is even rarer. Hepatic cavernous hemangioma can usually be confirmed by imaging, but old hemorrhage with cystic degeneration, as a unique imaging presentation, cannot be confirmed preoperatively. Therefore, hepatic cavernous hemangioma can easily be misdiagnosed as cystic adenoma or malignant tumor of the liver. Case presentation: A 66-year-old man was admitted to hospital with right upper abdominal distention and pain for 3 days caused by a mass in the right lobe of the liver that had been present for >10 years. Preoperative routine blood tests showed no abnormalities. Abdominal enhanced computed tomography showed a large, roughly circular lesion in the seventh segment of the liver, with clear borders and circumferential, ring-like high-density shadowing with no abnormal enhanced shadowing (~44 mm in diameter) after dynamic enhancement. The patient underwent surgery because of the possibility of malignancy. The postoperative specimen was pathologically confirmed as an old hemorrhage with cystic degeneration of hepatic cavernous hemangioma. Conclusion: The imaging presentation of this lesion may help in the diagnosis of atypical intratumoral hemorrhage of hepatic cavernous hemangioma.
