Congenital intracranial immature teratoma of the lateral ventricle: a case report and review of the literature.
OBJECTIVE
Congenital intracranial tumors are very rare and only account for 0.5-1.5% of all childhood brain tumors. The most common type of these tumors present at birth is teratomas, which represent 0.5% of all intracranial tumors. Most teratomas are midline tumors located predominantly in the sellar and pineal regions. In this study, we report a neonatal intracranial immature teratoma at the lateral ventricle because of its rare location.


METHODS
A 3-day-old female neonate presented with a history of irritability, vomiting, and recurrent generalized clonic seizures since birth. A head computed tomographic scan and magnetic resonance imaging disclosed a large tumor filling the right lateral ventricle and extending into the ipsilateral posterior fossa. With right parieto-occipital craniotomy, large grayish-white lobulated vascular mass was encountered and total removal of tumor was performed. Histological examination revealed the diagnosis of immature teratoma.


CONCLUSIONS
The prognosis of congenital intracranial immature teratoma is usually poor because the lesions are extensive when they are identified. Prenatal ultrasonography is necessary for the prenatal diagnosis. Fetal magnetic resonance imaging should be made for the evaluation of intracranial tumor. If the tumor is detected before the 24 week of gestation, termination of the pregnancy should be considered.
