The CT shows a focal opacity with speckled calcification with associated pleural thickening. The lesion showed minimal enhancement and was unchanged in appearance as compared to a radiograph obtained three years back. It is also called Blesovsky syndrome. There is loss of lung volume with associated adhesion of the lung to the pleura and fibrosis.
Plain radiographs show a rounded or ill-defined opacity with associated pleural disease.
CT is diagnostic showing an opacity with an acute angle with the periphery. Minimal to no enhancement is seen.
