ABSTRACT

Benign liver tumors are common and account for 83% of all hepatic tumors identified on diagnostic imaging or at the time of laparoscopy. Benign liver tumors may arise from either epithelial or mesenchymal cells (Table-1). In rare instances, a variety of miscellaneous disorders may masquerade as liver tumors. Hemangiomas and benign cysts constitute more than 50% of all hepatic lesions while focal nodular hyperplasia (FNH), metastatic tumors from a known or unknown primary cancer, hepatic adenomas and hepatocellutar carcinomas constitute the remaining common diagnoses.[1] Despite significant advances in diagnostic imaging modalities, the appearance of these lesions on imaging may not be always classical and biopsy or resection may be required in cases in which the diagnosis cannot be confidently made on imaging. The inability to exclude a possible malignancy is the most common indication for surgical intervention in a benign liver tumor.
