What are the potential complications of this condition?
1. respiratory distress/failure: infants>adults 2. haemorrhage 3. pneumothorax 4. fistula formation: aorta, SVC, oesophagus, bronchus 5. rupture bronchus: trichoptysis (expectoration of hair - very rare and highly specific) [ref 2] pericardium: pericardial effusion and tamponade pleural cavity: pleural effusion
Coronal scanogram: Left hemithorax showing a mass lesion which does not project above the clavicle and descending thoracic aorta can be clearly seen through it .This goes in favour of anterior mediastinal mass. CT scan confirmed the findings.
A large well-marginated heterogenous mass lesion of approximate size 11.5 x 9.5 x 7.5 cm containing fat, fluid and soft tissue components noted in anterosuperior mediastinum. No calcific foci noted within. The lesion abuts arch of aorta, great vessels arising from arch of aorta, left pulmonary artery and anterolateral chest wall without any definite invasion. Also note the pericardial effusion. There is mild enhancement of soft tissue components.
