A Case Report of Hydrocephalus in a US Military Recruit.

We present a case of chronic non-communicating hydrocephalus (NCH) in a US military recruit. Non-communicating hydrocephalus is a pathologic obstruction of cerebrospinal fluid (CSF) resulting in enlargement of the ventricles and elevated intracranial pressure. The patient is an 18-year-old male recruit who was evaluated in the Naval Medical Center emergency room for left hip pain and incidentally was found to have profound ventriculomegaly on head imaging.

Necrotizing osteomyelitis in a man with disseminated infection.
