Intradural Spinal Arachnoid Cysts in Children: A Collective Experience of 2 Centers

Abstract

Background: Pediatric intradural spinal arachnoid cysts are rare and can cause spinal cord or nerve root compression. Spinal arachnoid cysts can cause pain, motor/sensory neurological impairments, gait disturbances, spasticity, and bladder problems depending on their location. This study discusses the clinical aspects, management, surgical nuances, and postoperative clinical outcomes of symptomatic congenital intradural spinal arachnoid cysts, which are rarely seen in the pediatric population.

Methods: Our study involves a retrospective evaluation of 8 pediatric patients who underwent surgery for spinal intradural arachnoid cysts at the Department of Neurosurgery, Kocaeli University School of Medicine, and the Department of Neurosurgery, Selros University School of Medicine. The demographic data of all patients, preoperative/postoperative clinical findings, surgical procedures, surgical complications, and radiological imaging were evaluated.

Results: The average age of the patients was 8.7 uated. surgicrange:1-17).The female to male ratio was 4:4. The most common complaint was weakness in the lower extremities (87.5%). Urinary problems (50%) and sensory disturbances (50%) were less frequently observed. All patients had dorsal localization of the cysts. Cyst excision was performed in 7 out of 8 patients, and cyst fenestration was performed in 1 patient. Postoperatively, 7 patients showed complete symptom resolution, while one patient had partial improvement.

Conclusions: The success of surgical treatment depends on cyst location, neural tissue compression, and duration of symptoms. Complete removal or fenestration is determined by cyst location and accessibility. Intracystic shunts may be used in certain cases. Timely diagnosis and surgical intervention are crucial for improving neurological function in these rare cases.
