[Hydatid cysts of the brain. Diagnostic and therapeutic problems apropos of 100 cases]

The authors report 100 cases of hydatid cysts of the brain operated in the Neurosurgical Department (C.H.U. of Algier). They compars their data with those of the litterature. It appears once more that cerebral hydatidosis affects the children living in endemic countries and looks like a quite pure increased intracranial pressure. Supratentorial situation of the mass can be approached many times by the E.E.G. A right diagnosis is possible in almost all cases (6/7) by angiographic examination. Surgical technique is simple but one must keep a great attention in removing these "virulent" cysts. As a rule, the results are good, as far as the patients are not in a bad status before the operation. Unfortunately becalse of a late diagnosis, one patient among three is blind after the operation as he was before.
