title: FDG-PET imaging in primary bilateral adrenal lymphoma: a case report and review of the literature.
abstract: Primary adrenal lymphoma is an extremely rare entity. Only 70 cases have been reported in the English literature. Most of the patients are elderly men with bilateral adrenal masses without extraadrenal involvement. The most common presenting symptoms are fever, weight loss, lumbar pain, and/or symptoms of adrenal insufficiency. Of the cases reported, CT, ultrasound, and MRI were the imaging modalities used to describe the lesions. FDG PET has been used successfully to differentiate benign and malignant adrenal masses. The authors report a 67-year-old man diagnosed as having primary bilateral adrenal lymphoma and having no evidence of extraadrenal spread who was evaluated from the time of diagnosis to complete remission with FDG PET scanning. The literature of this unusual neoplasm is reviewed in detail.
