Abstract:
Spontaneous cavitation in primary lung malignancies although common, but is rare in secondary metastatic lung tumors. We present a case of 20-year-old male who presented with cavitary left lung lesion 1-year postexcision of the left tibia osteosarcoma on 18F-fluorodeoxyglucose positron emission tomography-computed tomography which on histopathology confirmed as metastatic lesion secondary to the sarcomatous primary.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
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...
