Magnetic resonance imaging of the spine showed a mass lesion in the conus medullaris region with nerve compression. The tumor was completely resected and diagnosed histologically as schwannoma. The patient recovered after surgery. Clinical and radiologic features of this rare tumor are reviewed and are...
surgeryBackground: Schwannoma is a benign tumor that originates from the cells of nerve sheaths. The occurrence of mobile schwannoma of the lumbar spine is extremely rare, and when clinicians perform spinal explorations in the expected locations, the results are often negative. This report presents...
Patients usually present with tinnitus, vertigo, and unilateral sensorineural hearing loss. Surgical approaches include the middle fossa and retrosigmoid approaches and are selected on the basis of tumor size and location and the possibility of hearing preservation. My preferred surgical approach...
The histopathologic study reported the tumor as schwannoma. The patient felt decrease in pain and numbness after the surgery. In about 3 weeks after, he was admitted again with low back and leg pains followed by hypoesthesia below Th9 levels. The patient then underwent the second laminectomy ...
Surgery via the transsylvian approach confirmed the origin of the tumor between the left internal carotid artery and the trigeminal nerve in the lateral wall of the cavernous sinus. Elongated abducens nerve was confirmed, but no tumor adhesion to the abducens nerve was found. The tumor was ...
As the anterior segment of the tumor expanded into the intrapelvic space and iliac arteries were stuck to it, an anterior approach should be better for tumor resection. However, postoperative pelvic instability was estimated based on the severely destructive image of the sacrum. At first, bone ...
Schwannomas can be surgically resected, although some patients have a large tumor burden that exceeds what can be approached by surgery. Most patients experience pain in association with their tumors; if surgery is not possible, chronic pain management is the only option for treatment. Pathogenesis...

A schwannoma is a common benign tumor of the peripheral nerve sheath. Schwannomas are rarely found in the foot and typically do not elicit any painful symptoms. We report the case of a large schwannoma eliciting tarsal tunnel like symptoms in a patient with a previous history of neurofibromatosi...
recurrent orbital schwannomatosis, manifesting as multiple independent schwannomas that likely arosede novo, contrasting with a 5-year old girl with a case of a recurrent isolated orbital schwannomas who underwent 2 surgical excisions with recurrence of the tumor within 1 month of each surgery. ...
