[Spontaneous ventriculocisternostomies].

A pantopaque ventriculogram is used to demonstrate spontaneous ventriculocisternostomy over the r. suprapinealis in a patient with benign occlusion of the aqueduct. Clinical remission corresponds to sufficient spontaneous liquor drainage. Thus, a total of thirteen real perforations of the third ventricle have so far been described in the literature in addition to nine complete lateral ventricular ruptures. The differences between incomplete ventricular wall ruptures, ventricular diverticula, and ventriculocisternostomies are discussed.
