Abstract:

Lung cancer (LC) and lymph node (LN) tuberculosis are two common entities around the world. 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography-computed tomography (PETCT) is frequently used in LC, because accurate lymph node (LN) staging is critical to choose appropriate treatment and to predict prognosis. However, increased 18F-FDG uptake is also seen in infected or inflammatory processes, such as tuberculosis. We reported a case of 57-year-old woman with lung cancer diagnosed by bronchoscopic biopsy with concomitant mediastinal and cervical LN involvement with malignant features due to the increased 18F-FDG uptake. However, mediastinal and cervical LN biopsies established the diagnosis of lymph nodes tuberculosis. There was no evidence of pulmonary tuberculosis. We concluded that NSCLC and primary LN tuberculosis was coexisted and the treatment approach was changed radically. The case is a good sample demonstrating vital importance of biopsying LN involvement with increased 18F-FDG uptake during lung cancer staging.
