The presentation in these patients varies from lethargic to obtunded to comatose, but some patients may be agitated and may have associated hemiplegia or hemisensory loss.[emedicine.medscape.com]
Sedation and muscle relaxation may be needed if agitated or resisting mechanical ventilation but these will have to be reversed before a full neurological assessment can be carried out.[patient.info]

Older individuals and ones with a higher grade of severity when admitted have a higher chance of a poor prognosis.[brain-surgery.com]
Prognosis is generally quite good with full or near full recovery expected at 6 months. Diagnosis is generally via MRI (see below). CT-angiography with 3D reconstruction has gotten good enough in recent years to be helpful too.[dizziness-and-balance.com]

The prognosis for the majority is good, with a large measure of functional independence. Wallenberg painted a distinctive picture, which has not been bettered after 100 years.[jnnp.bmj.com]
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]

[…] normal post-surgical angiographic reports of the aorta and arteries in the regions of the skull and kidney, the absence of any particular concerns being revealed in echocardiography, as well as normal CT scans of the abdomen excluded any of these as etiologies[brain-surgery.com]
MRI is frequently needed to make a specific diagnosis and to separate vascular etiologies from tumor and other structural injuries. The pattern of sensory disturbance may be helpful.[tchain.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]
However, in some patients, adequate collateral circulation prevents infarction in the territory of the occluded vessel. [9] The best way to test the safety of parent vessel occlusion is to perform a temporary balloon test occlusion, but this is impossible[asianjns.org]
In his case study, he emphasized a left occipital cortex lesion and also infarction of the splenium of the corpus callosum, which disconnected fibers from the right occipital lobe, preventing them from reaching the angular gyrus.[emedicine.medscape.com]
