The authors report a case of a huge posterior fossa arachnoid cyst with syringomyelia. This 22-year-oldman presented with a history of drop attacks. Magnetic resonance imaging demonstrated ventricular hy-drocephalus, a huge posterior fossa arachnoid cyst and syringomyelia. Cyst-peritoneal shunting was instal-led. The patient had an uneventful postoperative course, and his drop attacks disappeared. Magnetic reso-nance imaging one month after surgery showed reduction of the ventricular size and size of the arachnoidcyst and syrinx.

Large arachnoid cysts in the posterior fossa are reported occasionally, but rare with syrinx. The authorsdescribed this case to illustrate the possible contribution of the pathogenesis of the syringomyelia associ-ated with a huge posterior fossa arachnoid cyst.
