A case of portal hypertension due to an invasive hepatic hemangioma following a long-term disease course.

Hepatic hemangiomas, the most common benign liver masses, are often asymptomatic and do not require treatment; however, some subtypes develop complications, including diffuse hepatic hemangiomatosis, a rare disease in which hemangiomas replace the liver parenchyma. We describe a case in which the patient presented with esophageal varices. Upon admission, computed tomography showed a normal liver volume of 829 mL, 69% lower than the standard liver volume. Our findings suggest that in cases of large hepatic hemangiomas, regular imaging is necessary, especially if the liver volume falls below 70% of the standard volume; moreover, the possibility of complications should be considered.
