Abstract

Background: Hemangiomas are the most common benign tumors of the liver. Not all hepatic hemangiomas have characteristic or typical imaging findings. Objectives: Describe the clinical, subclinical and compute tomography characteristics of patients with hepatic hemangiomas. Methods: This was cross sectional study on 49 hepatic hemangioma patients diagnosed according to the guidelines of the European Association for the Study of the Liver in 2016. On contrast-enhanced CT images, hemangioma showed enhancement peripheral in arterial phase, afferent enhancement in delayed phase; diagnosed by histopathology when the tumor is not typical enhancement on CT. Results: The mean age of the patients was 54.7 ± 17.1. Female accounted for 55.1%. Abdominal pain had the rate of 46.9%. 100% of patients had normal AFP. HBsAg was positive in 4.1%, Anti HCV was positive in 2.0% of patients. The rate of right hemangioma was 67.3%. Number of solitary hemangioma was 73.5%. Tumor > 4 cm had a rate of 67.3%. Tumor size ranged from 1.9 to 10.2, the median size was 5.9 cm. On CT imaging, hemangioma was clear boundary with the rate of 97.9%. Typical enhancement hemangioma was 93.9%. 2.1% of patients had intra tumoral hemorrhage. Calcification in the tumor was seen in 2.1% of patients. Conclusion: Most hepatic hemangioma patients have no abnormal clinical and laboratory symptoms. Diagnosis is mainly based on typical CT imaging, liver biopsy should be considered when CT imaging is atypical.
