Nodular lymphoid hyperplasia in endoscopic and FDG-PET/CT (18F-fluoro-2-deoxyglucose positron emission tomography/computerized tomography) imaging

Abstract

Gastrointestinal nodular lymphoid hyperplasia is a rare lymphoproliferative state. In children, it is associated with familial immunodeficiency disease but most cases have no obvious etiology. In adults, nodular lymphoid hyperplasia is associated with immunocompromised status, including chemotherapy, acquired immunodeficiency viral infection, organ transplantation, and multiple polypoid lesions are noted in endoscopic findings and sometimes may be confused with family polypoid syndrome. We present a child with histological proof of focal intestinal nodular lymphoid hyperplasia that had a complete image study including negative results of 18F-fluoro-2-deoxyglucose positron emission tomography/computerized tomography analysis.
