Acute post-traumatic hydrocephalus (PTH) in an infant with mild head injury is a rare entity.
We report in this paper an 11-month-old baby who presented with acute PTH secondary to aqueductal obstruction by an intraventricular blood clot. The child recovered completely following a ventriculo-peritoneal shunt.
Acute hydrocephalus may develop secondary to aqueductal obstruction by a blood clot in children with even mild head injury.
