Key result
Hepatic anastomosing hemangioma is a rare benign vascular tumor with variable enhancement characteristics that can mimic malignancy on imaging, requiring histologic confirmation via biopsy.
Why the study?
Anastomosing hemangiomas rarely originate in liver parenchyma and can mimic primary and metastatic liver lesions on contrast-enhanced CT and MRI.
Case Report (n=1)
Hepatic anastomosing hemangiomas are rare benign vascular tumors that can mimic malignant lesions on imaging but can be definitively diagnosed via percutaneous biopsy, potentially obviating the need for surgical resection.
Anastomosing hemangiomas are a rare subtype of benign vascular hemangioma which most commonly arise in the genitourinary tract and retroperitoneum. In only a small number of reports has this entity been shown originating within the liver parenchyma. Despite their benign behavior, on contrast-enhanced computer tomography and magnetic resonance imaging studies anastomosing hemangiomas can demonstrate enhancement characteristics similar to primary and metastatic liver lesions. This case report highlights the imaging features of this entity and provides a brief review of the limited literature that exists on this rare hepatic lesion.

Merritt et al. (2019) conducted a case report in Anastomosing hemangioma of liver (n=1). Anastomosing hemangioma was evaluated on Imaging and histologic characteristics. Hepatic anastomosing hemangioma is a rare benign vascular tumor with variable enhancement characteristics that can mimic malignancy on imaging, requiring histologic confirmation via biopsy.
