Intramedullary Cavitation Resulting From Adhesive Spinal Arachnoiditis

Cervicothoracic arachnoiditis—a rare complication of aneurysmal intracranial subarachnoid haemorrhage

“…Spinal arachnoiditis was first reported by Nelson in 1943 [6] in a patient with previous history of spinal haemorrhage secondary to thrombocytopaenic purpura. The patients reported in various case reports were in the age group twenties to late sixties (22-69 years) [7] and the previous case reports showed female preponderance (86%).…”

Extensive arachnoid ossification with associated syringomyelia presenting as thoracic myelopathy

“…[13,21,42,53] Symptoms caused by arachnoid ossification are usually related to either external compression of the spinal cord by a piece of bone acting as a focal mass lesion [42] or by myelopathy secondary to circumferential compression of the cord by the ossified plaque or by the intramedullary syrinx formation. [35] In the former case, the symptoms may be more lateralized, whereas in the latter they resemble a usual course of diffuse myelopathy or syringomyelia. It is impossible, however, to render a diagnosis of arachnoid ossification on clinical grounds alone; however, it should be included in the differential diagnosis of progressive myelopathy or, in cases of caudal involvement, radiculopathy.…”

“…[45] The association between the arachnoid ossification and intramedullary syrinx, as we observed in our case, has been described in the past. [32,35,56] Here, again, the exact pathogenesis of the cavity formation inside the spinal cord is unknown. It has been suggested that focal disturbances of regional blood circulation, such as compression, stenosis or occlusion of the medullary vessels, may cause ischemic and gliotic changes in the dura mater of the spinal cord, eventually resulting in intramedullary cavitation.…”

Syringomyelia and spinal arachnoiditis resulting from aneurysmal subarachnoid hemorrhage: Report of two cases and review of the literature

“…[ 2 3 5 6 7 8 13 17 18 ] In 1943, Nelson was the first to describe spinal arachnoiditis after SAH. [ 4 ] His patient was a 50-year-old man with thrombocytopenic purpora who became myelopathic years after suffering an intracranial hemorrhage. On autopsy, the patient was found to have diffused intracranial and spinal arachnoiditis with syringomyelia.…”
