Abstract:
Pulmonary blastoma (PB) is a rare thoracic malignancy and preoperative diagnosis is challenging. A young man presented with dyspnea and chest pain for 3–4 months and chest-computed tomography (CT) revealed large mass in the left lung upper lobe and pleural effusion. Repeated CT-guided fine-needle aspiration cytology from the lesion and pleural fluid aspiration was negative for malignancy. F-18-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) revealed heterogeneous tracer avidity in left lung mass with areas of necrosis. Real-time PET-CT-guided biopsy from metabolically active component of the lesion revealed biphasic PB on histopathology.
