Metrizamide CT cisternography combined with Myodil (Pantopaque) cisternography in the investigation of suspected small acoustic neuromata.

A combined technique for the investigation of suspected small acoustic neuromata, involving the performance of a metrizamide CT cisternogram, a Myodil (Pantopaque) cisternogram, and also an estimation of the CSF protein level, all at the same examination, is described. An entirely negative result excludes an acoustic neuroma. A few illustrative abnormal cases are described.
