Abstract
Background
Congenital intracranial tumors are very rare and account for less than 2% of all childhood brain tumors. Teratomas constitute about one third to one half of these, predominantly located midline in the supratentorial region. Posterior fossa location rarely occurs and, based on the cases reported in the literature, commonly has a poor prognosis.
Case presentation
A newborn female, diagnosed prenatally with hydrocephalus, is presented at birth with increasing head circumference and Parinaud’s syndrome. Magnetic resonance imaging scans demonstrated a huge posterior fossa tumor with obstructive hydrocephalus. At surgery, through a suboccipital craniotomy, complete excision was achieved of a histological-proven immature teratoma. The infant received adjuvant chemotherapy for 1 year. She had normal neurological development and remained tumor-free through her 20-year follow-up.
Conclusion
The authors report this rare case of congenital posterior fossa teratoma with long-term outcome, and the literature is reviewed.
