In those 12 observations, without associated lesion in the brain stem, diagnosis is done 3 times at autopsy, 8 times at surgical time, and once before it, on clinical and radiographic arguments. Diagnosis must be systematically evoked in front of vestibular symptoms, before severe signs, related to intracranial hypertension and brain stem compression, become evident. Iodoventriculography (7 times) and principally computerized tomography (2 times) bring conclusive arguments for diagnosis. Those infarcts are situated 9 times in the territory of the postero-inferior cerebellar artery and 3 times in the area supplied by the antero-superior cerebellar artery. Spontaneous evolution is always lethal, but prognosis after surgery is still severe (4 long term survivals in 9 cases) for the vascular system of those patients remains fragile.
在这12例观察中，脑干无相关病变，3例在尸检时确诊，8例在手术时确诊，1例在出现严重体征（与颅内高压和脑干受压相关）之前，根据临床和影像学依据确诊。在出现前庭症状时，在与颅内高压和脑干受压相关的严重体征明显之前，必须系统地考虑诊断。碘脑室造影（7次）和主要是计算机断层扫描（2次）为诊断提供了确凿依据。这些梗死灶9次位于小脑后下动脉供血区域，3次位于小脑前上动脉供血区域。自然转归总是致命的，但手术后的预后仍然严重（9例中有4例长期存活），因为这些患者的血管系统仍然脆弱。
