Abstract:
A 33-year-old woman presents with cough and hemoptysis for 1 month. Chest CT showed a soft tissue mass in the left upper lobe of the lung. FDG PET/CT showed multiple foci of intense activity not only in the lung but also in the lymph nodes and the bones, which was diagnosed as lung malignancy with metastases. Histopathology revealed desmoplastic small round cell tumor. Our case indicated that, although the incidence is low, desmoplastic small round cell tumor should be considered among differential diagnoses of lung malignancies.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
