Abstract
AIM:
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.
MATERIALS AND METHODS:
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.
RESULTS:
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.
CONCLUSION:
In this Study Ultrasound remains the best tool to diagnose ACA . Postnatal and neurological outcome is favorable
