Mercury chronic toxicity might be associated to some cases of hydrocephalus in adult humans?

Mercury accumulates in nervous tissue causing neurological and psychiatric manifestations. Numerous clinical findings have been described in patients that suffered chronic mercury intoxication. Some findings, such as hydrocephalus, have been described only in experimental studies.

Epidural abscesses of the CNS.

Epidural abcessess can involve the intercranial or spinal compartments and can result in potentially devastating neurological injuries. Although rare, incidence of spinal epidural abscesses (SEAs) is increasing as predisposing factors such as injected-drug use, chronic immunosuppression, and spinal surgery become more common. Whereas symptoms of SEAs can include fever, back pain, and neurological dysfunction, the presentation of intracranial epidural abscesses (ICEAs) is less well defined.
