18F-FDG PET/CT Imaging In Primary Bilateral Adrenal Lymphoma

Abstract

The adrenal localization of a primary non-Hodgkin lymphoma is rare. We report a case of a 51-year-old man with adrenal insufficiency, cough and elevated eritrosit sedimantation rate. Conventional imaging studies ultrasonography (US) and computed tomography (CT) demonstrated bilateral bulky adrenal masses, and whole-body F 18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) showed that the masses and peripancreatic lymphadenopathy were the unique manifestations of this disease. The patient was eventually diagnosed with a diffuse large B-cell lymphoma after a CT-guided needle adrenal biopsy. The present case indicated that primary adrenal lymphoma should be included in the differential diagnosis of bilateral adrenal masses.

18F-FDG PET/CT Imaging In Primary Bilateral Adrenal Lymphoma

Öz

Adrenal kaynaklı primer non-Hodgkin lenfoma nadir görülen bir klinik durumdur. Bu vaka çalışmasında adrenal yetmezlik, öksürük ve sedimentasyon yüksekliği bulguları olan 51 yaşında bir erkek hasta sunulmaktadır. Konvansiyonel görüntüleme yöntemleri (ultrasonografi, bilgisayarlı tomografi) ve F- 18 fluorodeoksiglukoz pozitron emisyon tomografisi/ bilgisayarlı tomografi (18F-FDG PET/BT) tüm vücut görüntüleme ile büyük adrenal kitleler ve peripankreatik lenf nodları gösterilmiştir. 18F-FDG PET/BT görüntülerinde diğer vücut bölgelerinde patoloji izlenmemiştir. Bilgisayarlı tomografi eşliğinde yapılan adrenal iğne biopsisi sonrası diffüz büyük-hücreli non-Hodgkin lenfoma tanısı konuldu. Bu vaka çalışması bilateral adrenal kitlelerin ayırıcı tanısında primer adrenal lenfomanın da düşünülmesi gerektiğini göstermektedir
