Liposarkom des Mediastinums

Mediastinal

liposarcoma of thymic origin. CT shows an opacity in the left hemithorax which does not project above the clavicle (cervicothoracic sign). The descending thoracic aorta (arrows) can be seen through it, suggesting it to be an anterior mediastinal mass.

Mediastinal

liposarcoma of thymic origin. Axial NCCT shows a large well-marginated soft tissue density lesion of approximate size 12×9×8 cm in anterior mediastinum displacing the trachea to the right (T). Note the fatty components (HU -70 to - 100) (*)

Mediastinal

liposarcoma of thymic origin. The lesion abuts the anterior chest wall. Fat attenuation areas are marked (*).

Mediastinal

liposarcoma of thymic origin. Pericardial effusion (e)

Mediastinal

liposarcoma of thymic origin. The mass lesion abuts the arch of the aorta and the anterolateral chest wall. Asterisks indicate areas of fat. No mediastinal invasion is noted.

Mediastinal

liposarcoma of thymic origin. Anterior mediastinal mass abutting the left pulmonary artery (LPA) and anterior chest wall.

Mediastinal

liposarcoma of thymic origin. Coronal CECT showing the mass lesion and pericardial effusion (e). Fat components (*). Visualised part of the liver is normal.

Mediastinal

liposarcoma of thymic origin. Sagittal CECT showing the location of the mass (anterior mediastinum) and pericardial effusion (e)

Mediastinal

liposarcoma of thymic origin. Axial CECT Thorax shows heterogeneously enhancing soft tissue density mass in the anterior mediastinum with areas of fat (*) displacing the trachea (T) slightly to the right.

Mediastinal

liposarcoma of thymic origin. Coronal CECT showing the mass lesion and pericardial effusion (e). Fat components (*). Mild displacement of trachea (T) to the right is noted.
