Astounding recovery after resection of an intradural nerve sheath tumor in an adult male from Vietnam
BACKGROUND
Spinal cord tumors can be classified as intramedullary, intradural extramedullary, or extradural. The differential diagnosis of spinal cord tumors includes meningiomas, astrocytomas, ependymomas, metastasis, nerve sheath tumors such as schwannomas or neurofibromas, and multiple sclerosis plaques. Radiology can provide clues to the type of tumor, but a pathology evaluation of a specimen is necessary to provide an accurate diagnosis. These tumors can cause a variety of neurological symptoms from spinal cord compression including pain, weakness, and paresthesia. They are treated by surgical resection, with a variety of outcomes possible depending on the severity of the preoperative symptoms, location and extent of the tumor, and efficacy of the surgery performed.


CASE DESCRIPTION
A 59-year-old male from Vietnam came to the Atlanta Medical Center for evaluation of severe ride sided hemiparesis and paresthesias. He first noticed alterations in his handwriting and quickly deteriorated to the point of being unable to walk or move his right arm. A cervical spinal mass was identified and analyzed on magnetic resonance imaging. Surgical resection was performed under a microscope in a joint operation between an orthopedic surgeon and neurosurgeon. A specimen of the tumor was sent to pathology for further evaluation.


CONCLUSION
The mass was determined to be an intradural extramedullary schwannoma. The severity of the patient's symptoms and the location and size of the tumor made full recovery unlikely and postoperative quadriplegia a real possibility. The tumor was surgically resected, which led surprisingly, however, to a full and prompt resolution of the patient's symptoms. Less than 2 weeks after surgery, the patient was able to walk and had almost fully regained use of his hands.
