A 14-year-old girl, who had been suffering from intermittent fevers for 2 months, developed painful erythematous plaques on the lower extremities. Laboratory data revealed elevated C-reactive protein, lactate dehydrogenase, and aspartate aminotransferase/alanine aminotransferase (AST/ALT). Blood and urine cultures were negative. CT showed hepatosplenomegaly. F-18 FDG PET revealed multiple patchy uptakes ...

Neurolymphomatosis (NL) is a rare, unique subtype of lymphomatous infiltration of peripheral nerves. Clinical/radiologic diagnosis of NL is challenging. We report F-18 FDG PET/CT findings of a case of breast diffuse large B-cell lymphoma, in which NL developed regardless of regression of systemic lesions during induction chemotherapy. FDG PET/CT showed ...

Positron emission tomography (PET) using [F-18]2-fluoro-2-deoxyglucose (FDG) fused with CT ((18)F-FDG PET/CT) has been widely adopted in oncological imaging. However, it is known that benign lesions and other metabolically active tissues, such as brown adipose tissue (BAT), can accumulate (18)F-FDG, potentially resulting in false-positive interpretation. Previous studies have reported that ...
