PET-CT imaging of primary lung extranodal NK/T-cell lymphoma. (A) The CT component of the PET-CT scan shows an irregular mass in the right hilum, adjacent to the pulmonary vessels, with evidence of local invasion and airway compression. The lesion is characterized by irregular borders and lobulated appearance. (B) The fused PET-CT image reveals intense FDG uptake in the same right hilar mass, indicating hypermetabolic activity, consistent with a malignant process. The high SUV suggests aggressive tumor behavior. Increased FDG uptake is also visible in the surrounding tissue, raising concerns for possible lymphatic or adjacent structure involvement. CT, computed tomography; ENKTL, extranodal NK/T-cell lymphoma; FDG, fluorodeoxyglucose; PET-CT, positron emission tomography; NK/T-cell lymphoma; NK, natural killer; SUV, standardized uptake value.
