fourth ventricle- an irregular ventricle between the third ventricle and the central canal of the spinal cord ventricle- one of four connected cavities in the brain; is continuous with the central canal of the spinal cord and contains cerebrospinal fluid ...
After dural opening, the fourth ventricle is exposed through the telovelotonsillar fissure by cutting the tela choroidea or with a midline approach with vermian splitting. The exposure of fourth ventricle tumors by splitting of the vermis was first described by Dandy, who indicated that this can...

only 16 cases have been described in the literature. Arachnoid cysts in the fourth ventricle may cause obstructive hydrocephalus or cerebellar ataxia or cranial nerve palsy. Treatment of a fourth ventricular arachnoid cyst is complete or partial resection via a midline suboccipital approach. Recently,...
Most authors note the most frequent localization of ependymomas in the IV ventricle, its cavity or lateral eversions. The time of development of ependymomas varies from 6 months to 11 years. At the initial stage, the disease is asymptomatic for a long time; by the time the first clinical ...
We are looking from posterior. Behind the medial lemniscus is the dorsal brainstem. ▼内侧纵束(下图)位于中脑至脊髓上段之间的中线旁。 内侧纵束的病变可出现核间性眼肌麻痹,属于水平凝视麻痹。 The medial longitudinal fasciculus extends from the midbrain to the upper spinal cord next to the midline,...
A dorsal angular approach was made so that mechanical electrode damage was contralateral to the lesion, or a posterior approach through the fourth ventricle was employed to avoid electrode damage. The brains were sectioned coronally and sagittally and stained with a modifield Nauta-Gygax or Fink-...
A rare case of epidermoid cyst traversing the brain stem is presented. Computed tomography revealed the mass within the fourth ventricle; magnetic resonance imaging showed the dumbbell-shaped mass extending from the prepontine cistern to the fourth ventricle. Despite the high mortality and morbidity of...
