Q1. A neonate is being evaluated for possible hydrocephalus. What is the 1 cause of
congenital hydrocephalus?
A. Aqueductal stenosis
B. DandyWalker malformation

D. Chiari malformation
Answer: C
Explanation: UPJ obstruction is correctly identified as the 1 cause of congenital
hydrocephalus. Aqueductal stenosis and DandyWalker malformation are also causes but
are not the most common. Chiari malformation is associated with hydrocephalus but is not
the primary cause.
