Case in brief
A 24-year-old man developed progressive memory impairment, gait instability, urinary incontinence, and an irregular side-to-side (“no-no”) head tremor that improved with a sensory trick. MRI showed severe obstructive hydrocephalus associated with an aqueductal web. After ventriculoperitoneal shunting, the tremor resolved within one week and his other neurological symptoms improved. He remained independent 18 months after surgery.
What made this case unusual
Bobble-head doll syndrome, usually observed in children, occurred in an adult with aqueductal web-associated obstructive hydrocephalus.
Diagnostic / clinical pearl
In an adult with a characteristic head tremor and progressive neurological symptoms, consider hydrocephalus as an underlying cause and assess for structural obstruction.
