This study was undertaken to evaluate the need for neck and mediastinal lymph node dissection when dealing with carcinomas of this region.
A chest radiograph revealed left sided pleural effusion with mediastinal emphysema.
Magnetic resonance imaging is helpful in confirming the nature of a mediastinal hematoma.
AB - spontaneous mediastinal hematoma is rarely seen in hematologic malignancy.
The six benign lesions included three false-positive mediastinal lymph nodes in one patient.
