andy-Walker malformation is a rare intracranial congenital abnormality
of the brain occurring in about 1 in 35000 live births. It is characterized
by a classical neuropathological triad consisting of complete or partial
agenesis of the cerebellar vermis, cystic dilatation of the fourth ventricle
and enlargement of the posterior fossa. Treatment involves seizure control,
ventriculo-peritoneal/cystoperitoneal shunting and psycho-social therapy.
Although there is an extensive list of signs and symptoms associated
with the disorder, final diagnosis is dependent on imaging techniques.
Timely neuroimaging helps to diagnose the condition and the associated
anomalies as early as possible. It also helps to evaluate the recurrence risk
in subsequent pregnancies with timely diagnosis of the present disorder.
A male child of age two years was brought to our institution for chronic
seizure disorder since seven months of age in the out-patient department.
He began to have progressive increase in head circumference since one
year of age, limited cognition and motor skills for his age and had repeated
hospital admissions for convulsions. Cranial CT scan with contrast and plain
cranial MRI both revealed moderate hydrocephalus with cystic enlargement
of the fourth ventricle communicating into a large cystically dilated posterior
fossa, absent cerebellar vermis and absent septum pellucidum along with
hypoplastic cerebellum and polymicrogyria. A diagnosis of Dandy-Walker
malformation was made, and treatment was advised accordingly, including
anticonvulsants and need of ventriculo-peritoneal shunting, to which the
family consented to on a lateral date, after out-patient follow up. In the
absence of any antenatal and postnatal neuroimaging modality, the case
was being managed in line of hydrocephalus with chronic seizure disorder.
With the availability of cranial CT scan study, a definite diagnosis of Dandy-
Walker malformation could be made and further management could be
planned.
