Posterior fossa tumor

Posterior fossa tumor has a very different differential in an adult as opposed to a child.

Epidemiology

Although it is true that posterior fossa tumours are much more common in children than in adults the distribution does vary with age:

0 to 3 years of age: supratentorial > infratentorial

4 to 10 years of age: infratentorial > supratentorial

10 to early adult hood: infratentorial = supratentorial

adults: supratentorial > infratentorial

Overall 50-55% of all brain tumours in children are found in the posterior fossa.

Complications

Quarante et al report 2 new pediatric cases of posterior reversible encephalopathy syndrome (PRES) that developed after surgical resection of a posterior fossa tumor. Appropriate management includes supportive measures, antihypertensive agents, and antiepileptic drugs, if needed. Full recovery is the most likely outcome in line with previous articles 1).
