Abstract
Congenital intracranial tumour constitute only 0.5–1.5% and are usually associated
with poor prognosis. New advancement in imaging may help in early diagnosis. We presented
a case of giant fetal intracranial tumour diagnosed antenatally at 28 weeks of gestation
in sonography. The magnetic resonance imaging confirmed a large hetrogenous intracranial
mass with bilateral ventriculomegaly. Because of the large size of the tumor and associated
macrocephaly, the baby was delivered by caessaran section. On delivery, fetal head
size was 44.5 cm with wide suture and left facial nerve was involved. Ventriculoeritoneal
shunt was inserted on 4th postnatal day, however complete surgical resection of tumour
was not performed because of parents refusal. Neonate had rapid increase in head size
and expired on postnatal day 16th. The histopathological findings of mass demonstrated
a congenital immature teratoma. Neonate expired on 16th postnatal day. Antenatal diagnosis
of intracranial tumour is possible with advanced imaging modalities, however an early
diagnosis before second trimester is difficult. Prognosis is generally poor and depends
on size of tumour, histology and timely intervention.
