[Microtopography of cerebellopontine angle structures in acoustic neuroma]. 1979

A I Larin, and A N Konovalov, and S Iu Kasumova

The structures of the cerebellopontine angle in neurinoma of the auditory nerve were studied in autopsy material and during surgical intervention with the use of an operative microscope. Principally different variants of the relationships between the cerebellopontine angle structures and the neurinoma capsule in intra- and extracisternal localization of the tumor were revealed. The greatest difficulties occur in exposure of the capsule of an intracisternal neurinoma which is tightly connected with the structures of the cerebellopontine angle by means of strong connective-tissue trabeculae. In extracisternal localization of the tumor its capsule is easily separated from the arachnoid, which is pushed to the brain stem, because there are no trabeculae between these structures. The main source of blood supply to the tumor irrespective of its localization is the anterior inferior cerebellar artery.

UI	MeSH Term	Description	Entries
D009464	Neuroma, Acoustic	A benign SCHWANNOMA of the eighth cranial nerve (VESTIBULOCOCHLEAR NERVE), mostly arising from the vestibular branch (VESTIBULAR NERVE) during the fifth or sixth decade of life. Clinical manifestations include HEARING LOSS; HEADACHE; VERTIGO; TINNITUS; and FACIAL PAIN. Bilateral acoustic neuromas are associated with NEUROFIBROMATOSIS 2.

D009493	Neurosurgery	A surgical specialty concerned with the treatment of diseases and disorders of the brain, spinal cord, and peripheral and sympathetic nervous system.	Neurosurgeries
D011149	Pons	The front part of the hindbrain (RHOMBENCEPHALON) that lies between the MEDULLA and the midbrain (MESENCEPHALON) ventral to the cerebellum. It is composed of two parts, the dorsal and the ventral. The pons serves as a relay station for neural pathways between the CEREBELLUM to the CEREBRUM.

D002531	Cerebellum	The part of brain that lies behind the BRAIN STEM in the posterior base of skull (CRANIAL FOSSA, POSTERIOR). It is also known as the "little brain" with convolutions similar to those of CEREBRAL CORTEX, inner white matter, and deep cerebellar nuclei. Its function is to coordinate voluntary movements, maintain balance, and learn motor skills.	Cerebella,Corpus Cerebelli,Parencephalon,Cerebellums,Parencephalons
D002544	Cerebral Infarction	The formation of an area of NECROSIS in the CEREBRUM caused by an insufficiency of arterial or venous blood flow. Infarcts of the cerebrum are generally classified by hemisphere (i.e., left vs. right), lobe (e.g., frontal lobe infarction), arterial distribution (e.g., INFARCTION, ANTERIOR CEREBRAL ARTERY), and etiology (e.g., embolic infarction).

D001099	Arachnoid	A delicate membrane enveloping the brain and spinal cord. It lies between the PIA MATER and the DURA MATER. It is separated from the pia mater by the subarachnoid cavity which is filled with CEREBROSPINAL FLUID.	Arachnoid Mater,Arachnoid Maters,Arachnoids
D001158	Arteries	The vessels carrying blood away from the heart.	Artery
