Posterior-fossa myelography with ethyl iophendylate (Pantopaque) is a safe and accurate method for the diagnosis of lesions of the cerebellopontine angle and can be carried out with equipment available in most departments of radiology.
Before the examination a metallic marker is placed in the external auditory canal. After detailed questioning of the patient about allergic reactions, 9 to 12 ml of iophendylate is inserted by lumbar puncture. With the patient in the prone position and the neck hyperextended, the two-way tilt table is turned head down until the iophendylate has collected in the cervical region. The head is then turned to one side 45° and the oil is allowed to fill the cerebellopontine cistern and internal auditory canal, after which the vertebral, basilar, anteroinferior cerebellar, posteroin ferior cerebellar arteries, and the fifth and sixth nerves usually can be discerned. After the test the oil is collected in the lumbar area
