ABSTRACT

Schwannomas are usually solitary, encapsulated, and asymptomatic, benign neurogenic tumors originating from the nerve sheath. Schwannomas rarely show malignant transformation, however, require close monitoring. They are primarily located in the thorax in the costovertebral sulcus, may rarely originate from peripheral intercostal nerves. Less than 10% of primary thoracic neurogenic tumors originate from the peripheral intercostal nerves. The main treatment and diagnosis of schwannomas are complete surgical resection. We report a rare case of a 40-year-old male with asymptomatic schwannoma originating from an intercostal nerve which was found incidentally on his chest X-ray and was treated with surgery.
