FDG PET/CT in 2 Cases of Hepatic Pseudolymphoma.

Hepatic pseudolymphoma, also known as reactive lymphoid hyperplasia or nodular lymphoid hyperplasia, is a rare benign lymphoproliferative lesion. Preoperative diagnosis of hepatic pseudolymphoma is challenging. We present 2 cases of hepatic pseudolymphoma with focal intense FDG uptake on FDG PET/CT mimicking malignancy. These 2 cases suggest that hepatic pseudolymphoma should be considered as a rare differential diagnosis in patients with focal hypermetabolic hepatic lesion.
