Benign Solid Focal Lesions and Incidentalomas of the Liver

Silvio Marcio Pegoraro Balzan, Vinicius Grando Gava and Gustavo Felipe Luersen

Abstract

• Hemangioma (the most common benign solid hepatic tumor) and Focal NodularHyperplasia (FNH) seldom pose a clinical significant risk requiring a surgical procedure. </p><p> • Hepatic adenoma is a rare tumor that may cause significant morbidity from bleeding, rupture, or malignant transformation. It represents the most frequent indication for surgical intervention among solid benign hepatic tumors. </p><p> • Oral contraceptives have been associated with hepatic adenoma and FNH. Nonetheless this association is not clear for hepatic hemangiomas. </p><p> • Other benign solid tumors are of exceedingly low frequency. They are difficult to diagnose and exceptionally require surgical treatment. </p><p> • Despite most of hepatic incidentalomas in patients with and without known cancer are benign, some of them require follow-up or treatment and management of incidentalomas is challenging.
