Dissecting Aneurysms of the Posterior Inferior Cerebellar Artery

Neurosurgery, 1991
Abstract The authors present three cases of dissecting aneurysms of the posterior inferior cerebellar artery (PICA). A literature search revealed only three previous cases. Analysis of these six cases showed a unique clinical picture. Three patients developed subarachnoid hemorrhage, and the other three had ischemia.

Fenestration of the posterior inferior cerebellar artery

The Cerebellum, 2007
Fenestration of the posterior inferior cerebellar artery (PICA) is exceedingly rare. Only one known example - a right PICA fenestration, has been documented in the peer-reviewed literature. A left-sided PICA fenestration is presented in this unique case illustration.

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.

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 ...

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.

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.

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.

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.

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.
