title: Medulloblastoma With Obstructive Hydrocephalus in a Young Infant.
abstract: Medulloblastoma is the most common posterior fossa tumor diagnosed in young infants. The presentation of posterior fossa tumors in neonates is highly variable. We report the case of a 2-month-old child who presented with poor feeding and lethargy and was noted to have a fixed downward gaze. Head computed tomography revealed a posterior fossa mass that was pathologically consistent with a medulloblastoma. This case demonstrates the uncommon presentation of posterior fossa tumors in young infants.
