Abstract
INTRODUCTION: Brain arachnoid cysts (AC) are congenital or acquired malformations. Their prevalence in children ranges between 0.2 and 2.3% of the studied populations. Few reported studies exist where AC appears after a subdural haemorrhage. METHODS: We present one case of a symptomatic suprasellar AC after post-traumatic subdural haemorrhage in an infant. RESULTS: After endoscopic ventriculocystostomy, the child quickly improved and the cyst reduced in size. The child was monitored for 22 months and his neurocognitive development remained normal. CONCLUSION: Our case led us to the hypothesis that the inflammatory process due to subdural haemorrhage may locally result in arachnoiditis, and thus to the creation of a neomembrane, and eventually to cyst formation. This is also the case with the development of post-traumatic spinal AC.
