Extensive soft tissue mass within the middle and posterior portions of the superior mediastinum, extending into the neck.
The tissue is homogenous with minimal enhancement. No cavitation or calcification.
The trachea and left main bronchus are encased by the mass, with displacement and partially effacement.
There is also encasement of the major upper mediastinal vessels.
Abnormal soft tissue extends into the para vertebral region bilaterally, more extensive on the left, with a focal thoracic levoscoliosis.
The lungs are grossly clear. No pericardial or pleural effusion.
Further area of abnormal soft tissue encasing the suprarenal abdominal aorta, the celiac axis and the superior mesenteric artery. The appearances of this mass are similar to the mediastinal component.
