Abstract

The authors describe three patients of syringomyelia associated with posterior fossa tumor. The lesions were diagnosed by magnetic resonance imaging. Total removal of tumor without decompression of foramen magnum was done and regression of syringomyelia and improvement of symptoms were demonstrated. It is suggested that the blockage of cerebrospinal fluid flow at the foramen magnum by tonsilar herniation may play an important role in syrinx formation.
