AB  - Leptomeningeal cysts, which are cystic collections filled with cerebrospinal fluid, are rare complications following pediatric head trauma and surgical correction of craniosynostosis. These cysts develop due to cerebrospinal fluid pulsations and brain growth that cause expansion of the dural tears. Although primary repair of the dural defect is the definitive treatment, the risk of cyst recurrence remains. Factors that increase this risk include syndromic craniosynostosis, hydrocephalus, increased intracranial pressure, and inadequate duraplasty/cranioplasty. Here, we report the successful treatment of a child with a complex leptomeningeal cyst on one hemisphere, Crouzon syndrome, and hydrocephalus who showed no cyst recurrence over 2 years of follow-up. We have also reviewed the literature for predictors of post-repair cyst recurrence and preventive surgical techniques in patients with high risk of recurrence.
