The difference between hepatic adenoma and hemangioma is mainly the difference in etiology and imaging manifestation. 1. Different etiology: Hepatic adenoma, also known as hepatocellular adenoma, is a rare benign liver tumor; hemangioma is a congenital benign tumor formed mainly by proliferation of angioblasts during human embryonic period, which is mostly seen in the skin or soft tissues. 2. Different imaging manifestations: the two are mainly differentiated according to the CT of the upper abdomen. The CT imaging manifestation of hepatic adenoma is mainly that the adenoma shows low density or isodensity shadow, and the morphology is mostly round-like, with clear boundary and no lobe; in the enhancement scan, the whole tumor is obviously strengthened in arterial phase, and mildly strengthened in portal phase, and isodensity in delayed phase. The CT imaging of hemangioma is mainly low-density or slightly low-density round-like shadows with clear borders. Most of the lesions showed peripheral enhancement in the arterial phase of the enhancement scan, the contrast agent gradually expanded to the center in the portal phase, and the lesions were partially or completely filled in the delayed phase. Contrast “fast in and slow out” or “slow in and slow out” is the typical CT manifestation of hepatic hemangioma. Patients who are found to have hepatic adenoma or hemangioma should consult the doctor in time, complete the relevant examinations, make a clear diagnosis, and then adopt corresponding treatment plan.
