Hydrocephalus: a fatal late consequence of mumps encephalitis.

Common and usually self-limited diseases may occasionally have fatal consequences. Hydrocephalus is a very rare complication of mumps, with just a few cases reported in the literature. Here we report a fatal case of hydrocephalus presenting 19 years after mumps encephalitis. The long latency period between encephalitis and hydrocephalus-associated symptoms makes this case particularly interesting.
