Workup did not show evidence for cardioembolic or atheroembolic source. The presence of an extradural origin of PICA may be considered a predisposing factor for non-traumatic LMS associated with head and neck movement. [link.springer.com]

Etiology Clinical features Clinical features Structure affected Ipsilateral Dysphagia Gag reflex Hoarseness, dysphonia Nucleus ambiguus (motor neuron) Ataxia, dysmetria, dysdiadochokinesia Inferior cerebellar peduncle Horner syndrome Uncontrollable hiccups [amboss.com]

The etiological cause was thought to be intracranial vertebral artery occlusion with a baseline insitu atherosclerosis, in the presence of branches having their origin from one side and going to both PICA territories. [dusunenadamdergisi.org]

It is important to contrast these clinical manifestations with those involving strokes of the anterior circulation, as the etiology and treatment may differ. [casemed.case.edu]

Etiology: Most commonly caused by atherothrombotic occlusion of the vertebral artery (then posterior inferior cerebellar arteray and least often the medullary arteries. [medicine.uiowa.edu]

We provide two case presentations where the outcome was predicted and certain morbidities prevented with the employment of a multimodal neuromonitoring paradigm. [cureus.com]

Conclusions: Coiling of ruptured distal PICA aneury, with or without parent vessel occlusion, was feasible, relatively safe and effective in preventing early/medium-term rebleeding. [ajol.info]
