To present a rare case of multiple compressive thoracic intradural cysts with pathologic arachnoid ossification, review the literature and present the surgical options. Few reports have identified the existence of arachnoid calcifications and intrathecal cysts causing progressive myelopathy. The literature regarding each of these pathologies is limited to case reports. Their clinical significance is not well studied, although known to cause neurologic sequelae. ⋯ On last examination, the patient's neurologic status had not improved, but had stabilized. The rate of neurologic improvement from excision and decompression is variable, but it may still be warranted in the face of progressive neurologic deficits.

Intracranial haemorrhage is a rare complication of spinal surgery. Three cases of cerebral or cerebellar haemorrhages following spinal operations with CSF loss are reported, and the literature was reviewed. ⋯ The dangerous complication of intracranial haemorrhage has to be kept in mind when patients have moderate cerebral symptoms after CSF loss due to spinal operations.
