Click 28-year-old male with Tracheobronchopathia Osteochondroplastica presenting with expectoration, breathlessness and wheezing. Axial unenhanced CT images from thoracic inlet to the diaphragm. CT sections show presence of nodular wall calcification of inner tracheal lining and main bronchi with sparing of posterior wall. (128-channel MDCT scanner SOMATOM Definition AS, Siemens Medical Solutions, 120 kV, automatic mAs, detector collimation 128 0.6 mm, window width/level of 360 / 60 HU, 3 mm slice thickness).

Click 28-year-old male with Tracheobronchopathia Osteochondroplastica presenting with expectoration, breathlessness and wheezing. Axial contrast enhanced CT images from thoracic inlet to the diaphragm. CT sections show presence of nodular wall calcification of inner tracheal lining and main bronchi with sparing of posterior wall. Normal enhancement of mediastinal vascular structures is noted. No mediastinal lymphadenopathy is seen. (128-MDCT scanner SOMATOM Definition AS, Siemens Medical Solutions, 120 kV, automatic mAs, detector collimation 128 0.6 mm, 3 mm reformation and window width/level of 360 / 60 HU, 80 c.c. of 300 mg/ml iodine concentration non-ionic contrast given by hand injection).

Click 28-year-old male with Tracheobronchopathia Osteochondroplastica presenting with expectoration, breathlessness and wheezing. Coronal multiplanar CT reconstructed images reveals the extent of involvement of tracheobronchial tree. Lower two third trachea and main bronchi are affected with relatively spared upper third of trachea. (128-MDCT scanner SOMATOM Definition AS, Siemens Medical Solutions, 120 kV, automatic mAs, detector collimation 128 0.6 mm, 3 mm coronal reformation, 80 c.c. of 300 mg/ml iodine concentration non-ionic contrast given by hand injection).

Click 28-year-old male with Tracheobronchopathia Osteochondroplastica presenting with expectoration, breathlessness and wheezing. Axial HRCT lung images from thoracic inlet to the diaphragm. CT sections show presence of nodular wall calcification of inner tracheal lining and main bronchi with sparing of posterior wall. Luminal narrowing is appreciated in the main bronchi. Lung parenchyma is normal.
