Ventral mesencephalic lesions usually cause oculomotor nerve paresis by damaging the oculomotor nerve fascicle. The classic etiology is vascular. Information on how to subscribe to neurology and neurology:
Mid brain by DR.TATHEER
Weber syndrome, classically described as a midbrain stroke syndrome and superior alternating hemiplegia, involves oculomotor fascicles in the interpeduncular cisterns and cerebral peduncle, thereby causing ipsilateral third nerve palsy with contralateral hemiparesis.
In this lecture professor zach murphy will present on the four most common midbrain lesions including benedikt, weber, claude, and parinaud syndrome.
Weber's syndrome, also known as midbrain stroke syndrome or superior alternating hemiplegia, is a form of stroke that affects the medial portion of the midbrain. Weber syndrome, classically described as a midbrain st. Benedikt syndrome is an extremely rare eponymously named cluster of symptoms relating to anatomically specific damage of varying etiology to the midbrain. Contralateral cerebellar ataxia and/or holmes tremor and/or choreoathetosis.
To present a unique case of benedikt syndrome in a patient with isolated midbrain neurocysticercosis.
Click card to see definition 👆. The midbrain is already one of the smallest regions of the brain, and. It's usually caused by a stroke (infarction), but in rare cases, weber’s syndrome can also be caused by a brain tumor, a traumatic injury, or infection. Clinical practice can be found here.

It localizes specifically to the the ventral paramedian midbrain. Fascicular oculomotor (third) nerve palsy; Weber's syndrome and benedikt's syndrome: Maladie à corps de lewy = hypersensibilité aux neuroleptiques.

In this regard, what is weber’s syndrome? Valérie biousse, md departments of ophthalmology and neurology, emory university school of medicine: Benedikt syndrome is an eponymously named neurological condition secondary to specific damage in the midbrain that causes ipsilateral oculomotor nerve palsy, contralateral hemiparesis, and contralateral cerebellar ataxia and/or holmes tremor and/or choreoathetosis. Weber's syndrome is a neurological condition caused by an injury to the midbrain, the uppermost section of the brainstem.
Benedikt syndrome vs weber syndrome mnemonic for usmle,plab.
Weber’s syndrome, also known as. Benedikt syndrome, also called benedikt’s syndrome or paramedian midbrain syndrome, is a rare type of posterior circulation stroke of the brain, with a range of neurological symptoms affecting the midbrain, cerebellum and other related structures. Benedikt syndrome features ipsilateral oculomotor nerve palsy and contralateral weakness/clumsiness. It involves oculomotor fascicles in the interpeduncular cisterns and cerebral peduncle so it characterizes the presence of an ipsilateral lower motor neuron type oculomotor nerve palsy and contralateral hemiparesis or.
We highly recommend watching our midbrain anatomy & function lecture.
Because the fascicles of cranial nerve (cn) iii are scattered in their course through the midbrain, the third nerve palsy in any of these syndromes may be partial. Tap card to see definition 👆.
