In large volume cerebellar infarcts, neurosurgical treatment with occipital decompression or external ventricular drainage (EVD) can be lifesaving in patients who have acute hydrocephalus or raised intracranial pressure causing reduces consciousness 11. In PICA infarction, the outcomes are generally expected to be good 12. If the timing of diagnosis fits within 4.5 hours of the onset of symptoms, then patients can be treated with thrombolysis 9. Acute endovascular therapies, often in the form of lysis or clot removal, can be used, particularly in basilar artery occlusion 10. Treatment of posterior inferior cerebellar artery, and posterior circulation strokes in general, depends upon the nature, timing, and severity of symptoms. ![]() In the first twenty-four hours, studies show approximately 75-95% sensitivity for MRI diffusion-weighted images, compared to CT of 16% 8. MRI is far superior to CT in the sensitivity of acute ischemic stroke across all vascular territories. MR angiography and CT angiography both have very high sensitivity for vessel occlusion identification, at 87% and 100% respectively 7. ![]() CT angiography should be utilized if the patient fits thrombolysis therapy guidelines 6. As with all cases of suspected stroke, CT or MRI is required urgently to exclude hemorrhagic stroke.
