Potential value of apparent diffusion coefficient in the evaluation of hepatic pseudolymphoma.

Abstract

Hepatic pseudolymphoma, also called reactive lymphoid hyperplasia or nodular lymphoid lesion, is a rare benign non-neoplastic lesion that is histopathologically composed of lymphoid follicles, densely-infiltrated lymphoplasmacytic cells and epithelioid cells (1). The incidence of this disease among females is nine times that of males, which shows a significant gender preference (2). Most hepatic pseudolymphomas are asymptomatic, with an average onset age of 50 years (2).
