Bilateral thoracotomy for removal of uncommon postmediastinal multi-schwannomas.

Postmediastinal schwannoma is a kind of neurogenic tumor originating from the neuron sheath in the posterior mediastinum. In the majority of cases these tumors are located in the paravertebral sulcus and the incidence is similar in both sides of the thorax as single or multiple; however, multi-schwannomas involved in the bilateral postmediastinum are rare. We report a case of postmediastinal multi-schwannomas and discuss the clinical and surgical treatment. We are aware of no previously published reports on this rare condition.
