Pedunculated hepatic hemangioma
Pedunculated hepatic hemangiomas are rare benign tumors of of the liver. They can be asymptomatic or complicated by torsion, resulting in pain. They can create a diagnostic challenge when they are connected only by a thin stalk, and can be mistaken for a malignant mass.
Follow a typical enhancement pattern of hemangiomas with peripheral, nodular enhancement on early phases, which gradually fills in on portal venous and delayed phases. The thin stalk/pedicle is often undetectable on imaging.
