Aneurysm of the Posterior Inferior Cerebellar Arteries/Communicating Artery

Cerebrovascular Diseases, 2001
Only 3 cases of aneurysm associated with the communicating artery between both distal posterior inferior cerebellar arteries (PICAs) have been reported in the literature. We present the 4th case of such an aneurysm arising from the communicating artery itself, which is unrelated to the arterial branches.

Trigeminal artery connection to the posterior inferior cerebellar arteries

Neuroradiology, 1975
An example of the internal carotid artery supplying the posterior inferior cerebellar artery directly is reported. The direct PICA supply comes from a trigeminal trunk. There was no basilar artery opacification. An embryological explanation is given.

Peripheral Aneurysms of the Posterior Inferior Cerebellar Artery

Neurosurgery, 1984
Abstract Nonmycotic peripheral posterior inferior cerebellar artery (PICA) aneurysms are rare. The authors report six cases of peripheral PICA aneurysm. Two of these are unusual; one was fusiform and another was a double aneurysm arising from the peripheral PICA.

Extracranial aneurysm of the posterior inferior cerebellar artery

Journal of Clinical Neuroscience, 2007
Aneurysms of the posterior inferior cerebellar artery (PICA) are rare, and may arise in unusual locations due to the complex and variable anatomy of this artery. The PICA does not usually originate from the extracranial vertebral artery. Of the few reported extracranial PICA aneurysms, all affected the distal segment.

Thrombotic Aneurysm of Posterior Inferior Cerebellar Artery

World Neurosurgery, 2019
Spontaneous thrombosis of an intracranial aneurysm is rare but is common in fusiform or large cystic aneurysms, which result in subarachnoid hemorrhage after rupture. This case reports a 47-year-old woman with subarachnoid hemorrhage who developed spontaneous thrombosis of an aneurysm due to rupture of the posterior inferior cerebellar aneurysm.The ...

Extracranial Aneurysms of the Posterior Inferior Cerebellar Artery

Cerebrovascular Diseases, 2000
<i>Objective:</i> Extracranial aneurysms of the distal posterior inferior cerebellar artery (PICA) are extremely rare and sometimes difficult to diagnose without an adequate angiogram. We present the first series of 3 patients who were evaluated by the senior author and treated surgically.

Microsurgical Anatomy of the Posterior Inferior Cerebellar Artery

Neurosurgery, 1982
Abstract Fifty cerebellar hemispheres from 25 adult cadavers were examined. The posterior inferior cerebellar artery (PICA), by definition, arose from the vertebral artery. The vertebral artery was present in 49 and the PICA was present in 42 of the 50 hemispheres.

The angiography of posterior inferior cerebellar artery aneurysms

Neuroradiology, 1973
Twelve cases of aneurysm of the PICA are reported, the clinical histories summarized and the radiological evaluations reviewed. The importance of using subtraction techniques and of employing various special projections for adequate assessment of the anatomical relationship of the aneurysm to vital structures have been discussed.

Aneurysm of the Posterior Inferior Cerebellar Artery

American Journal of Diseases of Children, 1970
Medical literature describing intracranial aneurysms and their cause, effect, and treatment in adults is plentiful. However, aneurysms of the posterior fossa occurring in children are not common, and those specifically of the posterior inferior cerebellar artery in children are indeed a rarity.

Retrograde access to the posterior inferior cerebellar artery in balloon-assisted coiling of posterior inferior cerebellar artery aneurysms

Journal of NeuroInterventional Surgery, 2014
Introduction Balloon-assisted coil embolization of proximal posterior inferior cerebellar artery (PICA) aneurysms may be limited by the inferiorly oriented, acutely angulated origin of the PICA from the vertebral artery.
