The early diagnosis of acoustic tumors using posterior fossa cisternography with iophendylate.
Posterior fossa cisternography is a basic method for confirming the presence of acoustic and other tumors of the cerebellopontine angle. A modified outpatient procedure with use of new instrumentation is described here, and comparisons are made to the conventional hospital procedure. A series of patients selected for outpatient posterior fossa cisternography was studied using data processing techniques. Presenting symptoms and preliminary test results were compiled, and an impression established as to the likelihood of a tumor being present. Outpatient posterior fossa cisternography was performed, with examination under fluoroscopy in certain circumstances; surgery was performed in certain instances. The results of diagnostic procedures, surgical procedures, and follow-up studies were coded, analyzed by computer, and conclusions drawn.
