Paradoxic vocal cord syndrome with surgical cure.

Paradoxic vocal cord motion (PVCM) can cause wheezing, stridor, weak or absent voice, and ineffective cough. We have described a patient who had a posterior fossa arachnoid cyst, which was thought to be causing PVCM by compressing the brain stem. The PVCM and all symptoms resolved after surgical treatment of the arachnoid cyst.
