Giant Liver Hemangiomas: A Plea for Early Surgical Referral and Resection.

Hepatic hemangiomas are the most common benign hepatic tumor. Current guidelines recommend surveillance imaging and reserving surgical intervention for symptomatic patients with giant liver hemangiomas (>5 cm). We present the case of a patient with a rapidly enlarging giant hepatic hemangioma initially managed by surveillance. During her observation period, she developed weight loss, constipation, and pancytopenia concerning for Kasabach-Merritt Syndrome. Resection of the hemangioma was complicated by its large size (28.0 × 18.0 × 11.4 cm). Patients with rapidly growing giant liver hemangiomas, even when asymptomatic, should be promptly referred to specialized surgical centers for evaluation and management.
