ABSTRACT
A 14-year-old girl presented with recurrent, progressive lower leg weakness and decrease in sensation. When the symptoms first appeared, she was misdiagnosed as transverse myelitis and was treated with methylprednisolone. Eleven months later, when she had the same symptoms, spine magnetic resonance images showed the characteristic findings of spinal cord cavernoma and she underwent surgical intervention. Spinal cord cavernomas are rare lesions. Because of their highly bleeding tendency, acute neurological deterioration occurs secondary to hemorrhage within the spinal cord. In order to prevent intramedullary hemorrhage and to halt the progressive neurological decline, surgical resection is recommended. We experienced a case of spinal cord cavernoma presenting with recurrent transverse myelitis clinically.
