Purely extradural thoracal Schwanoma: Case report

and importance. Schwannomas are benign tumors that often occur in the medulla spinalis. It arises from the Schwann cells which form the sheath of peripheral nerves. Schwannomas comprise about 30% of primary intraspinal neoplasms and approximately 75% in intradural, 10% intra-extradural, and 15% extradural. Purely extradural schwannoma is rare.

We present two adult males with extradural thoracal schwannoma. In this case, the main complaint is paraparesis and followed by suffered low back pain and spastic. The initial symptoms of this tumor depend on the level of the tumor location. Usually begins with localized pain, sharp and transient, followed by radicular pain and radiculopathy. We reported cases of schwannoma of the thoracal spine that have presented with neurological involvement. As a result of contrast, an MRI of the spine showed tumor extradural mass lesion extending from thoracal 1-2 vertebral and thoracal 4-6 vertebral level.

The location of this tumor is rare because located in the extradural (15%), which are present between the bone structure and the dura. Surgery is the treatment of choice, in this case, usually results from excellent prognostic. This patient underwent hemilaminectomy and complete surgical resection.

Early diagnostic and complete surgical resection before the occurrence of severe symptoms will show an excellent prognosis.
