Thymic cyst causing superior venacava syndrome relieved by mediastinoscopy--a rare presentation.
Superior venacava obstruction is most often caused by intrathoracic malignant masses. The commonest cause of benign superior venacava obstruction is fibrosing mediastinitis. A thymic cyst causing marked superior venacava obstruction is very rare and has not been reported. We hereby present a case of a 40-year-old man with such a finding who presented with chest pain and facial congestion. Evaluation revealed a mediastinal mass causing marked superior venacaval obstruction. He underwent a mediastinoscopy, which showed a cyst. It was drained following which there was complete resolution of symptoms post-operatively. Histopathology of the lesion confirmed a thymic cyst.
