Weber, nothnagel, and claude syndromes. 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. The patient is a case of disseminated tuberculosis with granuloma in midbrain causing pressure effect, thereby presenting with features consistent with weber syndrome and upgaze palsy.
Weber syndrome Image
Weber syndrome is commonly caused by midbrain infarct secondary to occlusion of branches of the posterior cerebral artery and rarely from a tuberculoma.

Contralateral hemiparesis (involvement of cerebral peduncle containing corticospinal fibres which decussate in the medulla) benedikt’s syndrome (posterior cerebral artery) ipsilateral third nerve palsy. 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. Weber syndrome, classically described as a midbrain stroke syndrome and superior alternating hemiplegia,. Weber syndrome is a midbrain stroke characterized by crossed hemiplegia along with oculomotor nerve deficits.
Weber syndrome occurs with an occlusion of the median and/or paramedian perforating branches of the basilar artery.
We highly recommend watching our midbrain anatomy & function lecture. A syndrome of ipsilateral third nerve palsy and contralateral face and body weakness from injury to the paramedian midbrain. Clinical presentation ipsilateral cn iii pa. This activity reviews the etiology and the salient neurological findings in the patient with weber syndrome.

Weber syndrome is characterized by oculomotor palsy and contralateral hemiparesis. Occasionally the substantia nigra can also be involved 5. Exam reveals left eye third nerve ophthalmoplegia with impaired pupillary constriction and also right face. A review and understanding of the location and relationships between the different midbrain nuclei and fiber tracts will allow more precise correlation of radiologic findings with patient pathology and symptomatology.
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.

This activity reviews the etiology and the salient neurological findings in the patient with weber syndrome.
Also known as midbrain stroke syndrome and superior alternating hemiplegia, this condition is caused by a stroke in a branch of either the basilar artery or the posterior cerebral artery.
Here we shall review three syndromes in the midbrain occuring majorly due to a vascular event. Typical clinical findings include ipsilateral cn. Weber's syndrome is a distinctive brainstem disease characterized by ipsilateral 3rd nerve palsy with contralateral hemiplegia and is due to an intrinsic or extrinsic lesion in the ventral midbrain. Weber syndrome.—weber syndrome is caused by infarction of the oculomotor nucleus and cerebral peduncle in the ventromedial midbrain from occlusion of the paramedian branches of the basilar artery or posterior cerebral artery (1,4).
Particular syndromes associated with midbrain pathology include the weber, claude, benedikt, nothnagel, and parinaud syndromes.
