Posterior Inferior Cerebellar Artery Stenosis Presenting as Recurrent Orthostatic Dizziness

Isolated Posterior Inferior Cerebellar Artery Dissection

Spontaneous Isolated Dissection of the Posterior Inferior Cerebellar Artery Presenting with Lateral Medullary Infarction

Background: Spontaneous isolated dissection of the posterior inferior cerebellar artery (PICA) is rare and presents with variable clinical course and prognosis. We report a case of spontaneous isolated PICA dissection presenting with lateral medullary infarction. Case Report: A 57-year-old female patient presented with right leg ataxia, headache, nausea and vomiting with a past medical history ...

Coil embolization of posterior inferior cerebellar artery isolated aneurysms.

I read with great interest the article by Tikkakoski et al (1) describing their treatment of an isolated dissecting aneurysm of the left posterior inferior cerebellar artery with Guglielni detachable coils (GDCs). I would like to draw the authors’ attention to two additional articles relating to this subject. One article published in the Journal of Neurosurgery was a case report of an isolated ...

Dissecting aneurysm of the posterior inferior cerebellar artery.

Dissecting aneurysms of the posterior inferior cerebellar artery are an uncommon cause of stroke in the vertebrobasilar system, but they may also present with subarachnoid bleeding into the posterior fossa in 70% of the cases. Neither magnetic resonance imaging nor vertebral angiography show specific signs. Treatment should be neurosurgical to prevent rebleeding, although few cases have been re...

Intractable Hiccups Due to Posterior Inferior Cerebellar Artery Aneurysm

This is the third reported case of a posterior inferior cerebellar artery (PICA) aneurysm presenting as intractable hiccups (IH). A previously healthy 29-year-old woman was admitted with a 2-week history of hiccups occurring >100 times per minute. Symptoms persisted despite numerous noninvasive therapies. Magnetic resonance imaging and magnetic resonance angiogram of the brain showed a left PIC...
