Thoracic Myelopathy Secondary To Intradural Extramedullary Bronchogenic Cyst

Background/Objective: To report a case of thoracic myelopathy secondary to intradural extramedullary bronchogenic cyst.Study Design: Case report.Methods/Findings: A 20-year-old man presented to the emergency department with increasing back pain and lower-extremity weakness. Magnetic resonance imaging demonstrated a cystic lesion at the T4 level with mass effect on the spinal cord.Results: The lesion was resected, and histopathologic evaluation showed a cyst lined by respiratory-type epithelium consistent with a bronchogenic cyst.Conclusions: Intradural extramedullary bronchogenic cysts of the thoracic spine have been reported previously but are extremely rare. The treatment of choice is surgical resection.
