Figure 2: T1-weighted sagittal section of thoracic spine magnetic resonance imaging with extradural cystic lesion dorsally placed and pushing cord ventrally (a). The (b) T2 weighted sagittal section of thoracic spine magnetic resonance imaging shows same cyst with cerebrospinal fluid like intensity and ventrally displaced cord. The (c) axial section magnetic resonance imaging T2 weighted image confirms the extradural nature of cyst with thin hypointense dural wall seen. Intraoperatively (d) the cyst can be separated from normal dura and (e) postoperative specimen of same cyst
