Abstract
We report the long-term outcome of surgery for cerebral hydatid cyst in 12 children. In only one child, who had been operated on for cardiac hydatidosis a year earlier, was the brain cyst known to be secondary. Of the 12 children, 10 had a single cyst and 2 had multiple cysts. Five single cysts were removed intact by "hydatid birth," two cysts--one single and one multiple--were removed after puncture and aspiration of the cyst fluid, and the other five--four single and one multiple--were accidentally ruptured in the course of the operation. One patient died of infection of the residual space, 2 died of intracranial recurrence of the parasite (7 and 22 months later, respectively), and one, the child with secondary cerebral echinococcosis, died 6 years later of systemic echinococcosis. Eight patients who had a mean follow-up of 28 years are still living and enjoy very good health, both general and neurological. This long-term follow-up with such good results confirms the usually primary character of cerebral hydatid disease, at least in children. The combination of patent ductus arteriosus and ingestion of unboiled animals' milk might well explain how primary cerebral hydatid disease develops in children.
