Abstract:
We report the case of a 69-year-old man who presented with a rounded atelectasis (RA). During a 10-year follow-up by Computed Tomography (CT), the lobe showed a progressive shrinkage, and a moderate increase in size of the lesion led to a percutaneous biopsy which confirmed the diagnosis. RA is an unusual form of lung consolidation. The major cause of RA is asbestosis. RA is usually asymptomatic and may simulate a pulmonary neoplasm on chest Xray. The diagnosis is made by CT, demonstrating the pathognomonic "comet tail sign". No treatment is required.

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...
