Which of the following is a potential complication of very large hepatic hemangiomas?

Very large hepatic hemangiomas can trap and consume platelets within the tumor, leading to a consumptive coagulopathy known as Kasabach-Merritt phenomenon. In these big vascular lesions, ongoing intratumoral coagulation uses up platelets and coagulation factors, so patients develop thrombocytopenia and low fibrinogen with abnormal clotting tests. This creates a real bleeding risk and explains why a coagulopathy can accompany a giant hemangioma. This is the most specific and recognized complication among the options. Spontaneous rupture with intraperitoneal hemorrhage can occur but is less common. Malignant transformation to hepatocellular carcinoma is not a typical feature of benign hemangiomas, and severe hepatic failure within hours is not a characteristic complication of these lesions.
