ABSTRACT

Arachnoiditis ossificans (AO) is a rare entity in which calcifications are observed around the dural sac accompanied by pain and progressive neurological symptoms. It is the final stage of adhesive arachnoiditis, secondary to chronic inflammatory processes resulting from, for example, previous spinal surgeries, spinal infections, myelography with intraspinal contrast, anesthesia or intrathecal medication, subarachnoid hemorrhage, spinal tumors, etcetera. The case of a patient with multiple spinal surgeries, spinal infection and a progressive neurological picture with spasticity and neurogenic bladder is presented. Intradural calcification from T2 to S1 is observed on CT, with a circular and "honeycomb" pattern in the cauda equina region. In RNM syringomyelia and associated arachnoid cysts. It is interpreted as AO, and given the extent of the lesions and their calcification pattern, conservative treatment is decided. This pathology should be suspected in the presence of progressive neurological symptoms with no other apparent cause, in patients with related causes of AO. A CT should be requested for its study, where calcic plaques will be identified, and MRI to observe associated lesions or fibrosis where new calcified regions could arise.
