cisterna magna

The cerebellum frequently falls away from the posterior surface of the temporal bone after the cisterna magna has been opened.

Cerebellomedullary cistern (Cisterna magna) - the largest of the subarachnoid cisterns.

It was there that he invented an approach for obtaining cerebrospinal fluid using a cannula to the cisterna magna in the brain of cats.

The cisterna magna is located between the cerebellum and the dorsal surface of the medulla oblongata.

This is caused by open communication of the posteroinferior fourth ventricle and the cisterna magna through the enlarged vallecula.

The needle is placed in the midline, passing just under the occipital bone, into the (usually large) cisterna magna (Fig. 23-2).

Cerebral spinal fluid can also be obtained by puncture of the cisterna magna (cistern puncture).

Cerebrospinal fluid produced in the fourth ventricle drains into the cisterna magna via the lateral apertures and median aperture.

It is done by inserting a needle through the skin below the external occipital protuberance into the cisterna magna and is an alternative to lumbar puncture.

He described the surgical technique of ventriculocisternostomy (lateral ventricle to cisterna magna,; a predecessor of today's endoscopic third ventriculostomy), which is also called "Torkildsen's operation".

The median aperture ('"medial aperture," "Foramen of Magendie"') drains CSF from the fourth ventricle into the cisterna magna.

The cisterna magna (or cerebellomedullary cistern) is one of three principal openings in the subarachnoid space between the arachnoid and pia mater layers of the meninges surrounding the brain.

These represent closely associated forms of the disorder: DWS malformation, DWS mega cisterna magna and DWS variant.

Fluid may be OUR CEREBRUM 167 obtained, with greater difficulty, from the cisterna magna, or even from the ventricles themselves if conditions are grave enough to warrant drilling a hole through the skull.

They showed acromesomelic shortening, craniofacial characteristics with absence of craniosynostosis, small kidneys with tubular and glomerular microscopic cysts, persistent ductal plate with portal fibrosis in the liver, small adrenals, an enlarged cisterna magna and a posterior fossa cyst.
