Spinal arachnoid cyst associated with arachnoiditis following subarachnoid haemorrhage in adult patients: A case report and literature review

Abstract

Subarachnoiditis and associated arachnoid cyst can cause severe morbidity. This rare situation (which especially occurs following subarachnoid haemorrhage of posterior fossa) should be known and physicians should keep in mind that it requires urgent surgical procedure.

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%).…”

Thoracolumbar meningeal fibrosis in pugs

“…The spinal cord lesions from the pugs with thoracolumbar myelopathy in this study shared many features with the spinal cord of laboratory dogs, used in research about adhesive, also called constrictive, arachnoiditis . Adhesive arachnoiditis, a rare chronic myelopathy in people, is characterized by meningeal fibrosis that has been described to cause disruption of the vascular supply and the development of arachnoid diverticula, syringomyelia and myelomalacia . Familiar adhesive arachnoiditis, with a suggested genetic influence, has been described .…”

“…39,40 Adhesive arachnoiditis, a rare chronic myelopathy in people, is characterized by meningeal fibrosis that has been described to cause disruption of the vascular supply and the development of arachnoid diverticula, syringomyelia and myelomalacia. [41][42][43][44][45][46] Familiar adhesive arachnoiditis, with a suggested genetic influence, has been described. [47][48][49] In process dysplasias, are difficult to document without CT. 3 Although a previous study, including pugs of similar age as in the present study, could not confirm an association between CVMs and neurological signs, it has been suggested that some CVMs in pugs are indeed clinically significant.…”

Spontaneous spinal subarachnoid hemorrhage with residual arachnoid cyst: a case report

“…Arachnoid cysts can be asymptomatic or can cause neurological deterioration (4,12). Surgical decompression and shunt placement are the most common procedures in the treatment (1). But conservative management is also recommended in some cases (4,8).…”

“…Spinal arachnoid cyst due to arachnoiditis after subarachnoid hemorrhage (SAH) is also rare and usually presents as deterioration of neurological condition after several weeks to years from initial event (1).…”
