Focal Nodular Hyperplasia in a Young Male as an Incidental Finding Associated With Acute Lithiasic Chronic Cholecystitis. Case Report and Literature Review

Abstract

Focal nodular hyperplasia (FNH) is considered the second most frequent benign liver tumor with a low prevalence, with a broad predominance in the female population. Most cases are asymptomatic and are often discovered incidentally. Diagnostic imaging through MRI, CT, and ultrasound can be achieved in up to 80% of cases. In some cases, a histopathological study may be necessary, especially in view of the diagnostic uncertainty and suspicion of malignancy. To date, the management of these lesions remains controversial, conservative management is recommended for asymptomatic or small lesions, relegating surgical treatment only in cases of symptomatic lesions or uncertain behavior.
