“…The proposed etiologies for the perineural cysts include ischaemic degeneration, inflammation, hemorrhage, trauma, arachnoid proliferation, obstruction of perineural lymphatic flow or developmental origin [1,3,[8][9][10][11]. Several authors have proposed that increased CSF hydrostatic pressure may be a factor in the origin of perineural cysts or their growth and becoming symptomatic [4,12,13]. The patient in this study had a history of heavy lifting at work-maneuver that raises CSF pressure.…”

“…On the contrary, most surgeons, including ourselves, consider the cysts to be a congenital arachnoidal defect. 1,[12][13][14][15] A postulated mechanism involves a potential or very small "ball-valve" communication (also called "traffic pore") between the congenital pouch (the cyst) and the subarachnoid space, by which CSF can flow into the pouch but not exit. Therefore, the cysts can enlarge progressively because of continuous 1-way infusion of CSF.…”

BACKGROUND AND PURPOSE:Although often asymptomatic, enlarging sacral arachnoid cysts can also cause significant discomfort. These symptomatic sacral arachnoid cysts require specific treatments to facilitate local decompression. The main drawback of the surgical managements is the high risk of recurrence and complications. To decrease risks, we had been attempting to seek a simple and safe method to manage the symptomatic sacral arachnoid cysts. CT-guided percutaneous fibrin glue therapy is a new nonsurgical alternative. To evaluate the efficacy of the novel nonsurgical approach, we conducted this retrospective study of 38 patients.

“…This theory, however, does not explain the occurrence of arachnoid cysts ventral to the spinal cord [4, 6]. Strully [7] hypothesized that arachnoid cysts formed due to the presence of areas of lower resistance in the arachnoid, which may be dilated by the continued stress caused by the normal daily variations in CSF hydrodynamics. Fortuna and Mercuri [8] suggested that arachnoid granulations become trapped in various locations and cyst formation results from CSF production and sequestration along the path of resistance.…”

The authors report a 7-year-old girl who presented with progressive quadriparesis which had started a month before admission. Magnetic resonance imaging of the spine revealed an intramedullary cystic lesion extending from C₂ to C₄. After performing a C_2–5 laminectomy, the cyst was drained and anatomically fenestrated with the subarachnoid space by a 1-cm vertical median myelotomy without using a stent. The histopathological findings revealed arachnoid cyst. In the first month after operation, the neurological deficits disappeared gradually, except for a slight left upper paresis. Cervical spinal intramedullary arachnoid cyst is extremely rare and should be considered in the differential diagnosis of intramedullary cystic lesions in childhood. Recovery is possible after subtotal excision and fenestration of the cyst to allow communication with the subarachnoid space even if neurological deficits are present for a long time.
