- Abstract
Background: Abnormal cerebellar development manifests as a spectrum of disorders classified as malformations of paleo- cerebellum and neocerebellum. Dandy walker complex or malformation, is a disorder of paleocerebellum featured by the enlargement of the fourth ventricle, a partial or complete absence of cerebellar vermis and cyst formation near the base of the skull. The condition may go unnoticed or may occur with symptoms resulting in severe disabilities or even death". Case report: The present case report describes antenatal, ultrasonographic finding in a 22 year old primigravida, suggestive of a single live intrauterine gestation with BPD (42 mm), head circumference (173 mm), abdomen circumference (163 mm) fetal femur length (42 mm) corresponding to gestational age of 24-weeks. The fetus presented with dilated fourth ventricle, underdeveloped posterior wall structures (Cerebellar vermis and splaying cerebellar hemispheres) and hydrocephalus. Treatment: A special tube or shunt to reduce intracranial pressure may be placed inside the skull to control swelling along with of various therapies such as occupational therapy, physical therapy, speech therapy or specialized education. Conclusions: Prenatal diagnosis of Dandy walker is possible with antenatal ultrasound but differentiation from the posterior fossa anomalies likes mega cistern magna and retrocerebellar arachnoid cyst is important. Distinction between Dandy walker variant and mega cistern magna in the fetus is difficult as definitive criteria have not been firmly established. The former condition should be suspected when a thin communication is found between the fourth ventricle and cisterna magna. The latter when the cistern magna has a depth greater than 10 mm151. Ultrasound remains useful modality to detect and differentiate such congenital anomalies.
