A Case of a Thoracic Spinal Intradural Arachnoid Cyst with Chest Pain / 대한소아신경학회지

Spinal arachnoid cysts are relatively uncommon lesions that may be either intradural or extradural, while intradural spinal arachnoid cysts are even less common. The cysts are filled with clear, and colorless fluid nearly identical to cerebrospinal fluid. The origin of these cysts remains unclear although congenital, traumatic, and inflammatory causes have been postulated. These cysts are usually asymptomatic but may produce symptoms by compressing the spinal cord or nerve roots suddenly or progressively. The treatment of choice is surgical excision or fenestration, which is indicated when there are features of cord compression. We report a case of a thoracic spinal intradural arachnoid cyst in 13-year-old girl with chest pain.
