18F-FDG PET/CT Findings in a Patient With Primary Primitive Neuroectodermal Tumor of the Lung

Primary primitive neuroectodermal tumor of the lung is an extremely rare and highly malignant neoplasm with a poor prognosis. A 49-year-old man presented with a dry cough and slight pain in the left chest for nearly 1 month. F-18-FDG PET/CT showed intense F-18-FDG uptake of the left inferior lung tumor and hypermetabolic mediastinal lymph nodes. Histopathology revealed primitive neuroectodermal tumor after CT-guided transthoracic needle biopsy of the left inferior lung mass was performed.

Automated summary
