%X Leptomeningeal cyst (LMC) is a known complication of pediatric head injury but has not been described following a craniotomy other than for craniosynostosis. We present the case of a 20-month-old boy who underwent craniotomy for a traumatic epidural hematoma. There was an inadvertent tear of the dura which was repaired with a pericranial patch and dural sealant. The patient presented with a progressive surgical site swelling 5 months post-surgery and a CT scan revealed an LMC with elevation of the bone flap. He underwent re-exploration with watertight repair of the dural defect and rigid fixation of the bone flap. This iatrogenic LMC provides an opportunity to compare and confirm the pathogenesis vis a vis the more common spontaneous post-traumatic LMC. Our report highlights the importance of proper dural closure and bone fixation after craniotomy in children whose skulls are still growing.
