A unique intersection: Exploring an exophytic, pedunculated hepatic hemangioma with gastric connection in a case...

Hepatic hemangiomas are commonly benign liver tumors, typically asymptomatic and predominantly located in the right lobe. This case report details an exceptional instance of a left-lobe hepatic hemangioma manifesting as an exophytic, pedunculated mass resembling a gastric tumor. A 77-year-old woman with a history of melanoma presented with a mass incidentally discovered during evaluations for chest pain. Advanced imaging techniques, including computed tomography (CT) and endoscopic ultrasound (EUS), identified this mass as a benign, pedunculated hemangioma extending from the left hepatic lobe toward the gastric fundus. Given the tumor's benign nature and the patient's lack of symptoms, a conservative management approach was adopted. This case emphasizes the importance of accurate imaging and diagnostic assessment in managing atypical hepatic hemangiomas, highlighting the need to carefully consider rare growth patterns and locations in differential diagnoses to avoid unnecessary interventions. Such cases reinforce the complexity of diagnosing and managing unusual presentations of common benign tumors.
