Arachnoid cysts are a rare central nervous system malformation. Antenatal features and Clinico-pathological features and surgical management strategies for Antenatal diagnosed Arachnoid cysts are discussed.


The Author from August 2009 until May 2018, reviewed records of 11 children who underwent surgical treatment for Antenatal diagnosed Arachnoid Cyst [AAC]. Their Antenatal Characteristic, Associated abnormality, clinical, radiological features and management including follow-up were analyzed. In 5 children were diagnosed before 30week gestational age and 6 were after 30weeks. In 3 cases a fetal MRI was performed. 10 AAC were supratentorial and 1 AAC was located in the posterior fossa. There were 7 males and 4 females, Age at surgery ranged from 2 days to 13 months with mean of 3.4 months.


All the children underwent Surgery in form of Cystoperitoneal shunt [n=7], endoscopic fenestration [n=3], craniotomy and marsuplization [n=1]. Follow-up duration ranged from 4 month to 5.7 years with mean of 30 months. 2 children needed cystoperitoneal shunt after endoscopy. All the children normal neurologically.


In this Study Ultrasound remains the best tool to diagnose ACA . Postnatal and neurological outcome is favorable
