Imaging findings of expansile lesions of the thymus.

The purpose of this article is to review the imaging findings of the different expansile lesions of the thymus. Almost 50% of all mediastinal masses are located in the anterior mediastinum. The thymus is the most common site of origin of these masses.

Tracheobronchopathia osteochondroplastica: helical CT findings in 4 cases.

Tracheopathia osteochondroplastica is an uncommon abnormality of the cartilaginous tracheal wall, characterized by the presence of osteocartilaginous calcified nodules within the submucosa, with variable degree of diffuse tracheal narrowing. Imaging findings in CT are characterized by the presence of calcified nodular densities protruding into the tracheal lumen, with an abnormally irregular tracheal morphology and often decreased lateral diameter. This can extend to the proximal main stem bronchi.

Association of two respiratory congenital anomalies: tracheal diverticulum and cystic adenomatoid malformation of the lung.

Many associations of congenital anomalies of the respiratory system have been reported, but the combination of tracheal diverticulum and cystic adenomatoid malformation (CCAM) is unique. We present a patient with these two anomalies and analyze their embryological correlation.
