Recovery of Deglutition Disorder in Posterior Inferior Cerebellar Artery Stroke-A Case Reports

AbstractAnterior inferior cerebellar artery–posterior inferior cerebellar artery (AICA-PICA) variant or common trunk is seen frequently in vertebral angiograms as PICA is found to be hypoplastic or absent in approximately 20 to 25% of patients. There have been very few case reports of aneurysm arising in AICA-PICA variant. Intrameatal AICA aneurysms are also rare, with no reports involving AICA-PICA variant till date. Neurosurgical approach and clipping have been proposed as first-line treatment option for intrameatal AICA aneurysms. The authors report a case of a young woman presenting with subarachnoid hemorrhage, found to have a right AICA-PICA variant aneurysm in intrameatal location. The patient underwent coiling with parent vessel occlusion after an unsuccessful attempt at surgical management of the same. She recovered without any postprocedure complication. This case report highlights the fact that endovascular approach can be used to manage distal AICA/AICA-PICA variant or intrameatal aneurysm with added advantage of avoiding the postprocedure complications associated with surgical management of the same.

AbstractObjective:This paper reports on two patients with posterior inferior cerebellar artery infarction whose only presenting complaint was acute unilateral hearing loss.Case reports:In the two cases reported, sudden hearing loss was an initial symptom, with no other neurological signs. Infarction in the territory of the posterior inferior cerebellar artery was diagnosed using brain magnetic resolution imaging. The patients had some degree of hearing improvement 3 or 4 days after initial treatment.Conclusion:In this article, new cases of posterior inferior cerebellar artery infarction presenting as sudden deafness, without prominent neurological signs, are described. Otologists should be aware that hearing loss can sometimes appear as a warning sign of impending posterior inferior cerebellar artery infarction.

Cerebellar Artery

Abstract The distal posterior inferior cerebellar artery (PICA) is a rare site of aneurysm formation. Only small case series and case reports regarding surgical treatment are found in the literature. The PICA is divided into 5 segments (anterior medullary, lateral medullary, tonsilomedullary, telovelotonsillary, and cortical), and the distal ones represent the most complex, due to anatomic variations. We present a case of a 69-yr-old female patient who has suffered from a sudden and intense occipital headache, associated with nausea and vomiting. CT scan showed intraventricular hemorrhage, and further investigation with MRI and MR Angiography revealed a small distal PICA aneurysm, at the superior part of the medial aspect of the left cerebellar tonsil. Digital angiography has demonstrated the aneurysm at the tonsilomedullary segment of the PICA. In this 3-dimensional video, the authors show the microsurgical clipping of a saccular distal PICA aneurysm in the close relation to a choroidal branch, performed by median suboccipital craniotomy. Step-by-step of the dissection, relevant surrounding anatomy and aneurysm clipping is demonstrated. The patient signed the Institutional Consent Form, which allows the use of his/her images and videos for any type of medical publications in conferences and/or scientific articles.

Arterial Malformation

OBJECTIVEOver the last half century, there have been isolated case reports of purely arterial malformations. In this study, the authors report a consecutive series of patients with pure arterial malformations, emphasizing the clinical and radiological features of these lesions.METHODSPure arterial malformations were defined as dilated, overlapping, and tortuous arteries with a coil-like appearance and/or a mass of arterial loops without any associated venous component. Demographic characteristics of the patients, cardiovascular risk factors, presentation, radiological characteristics, and follow-up data were collected. Primary outcomes were new neurological symptoms including disability, stroke, and hemorrhage.RESULTSTwelve patients meeting the criteria were identified. Ten patients were female (83.3%) and 2 were male (16.6%). Their mean age at diagnosis was 26.2 ± 11.6 years. The most common imaging indication was headache (7 patients [58.3%]). In 3 cases the pure arterial malformation involved the anterior cerebral arteries (25.0%); in 4 cases the posterior communicating artery/posterior cerebral artery (33.3%); in 2 cases the middle cerebral artery (16.6%); and in 1 case each, the superior cerebellar artery, basilar artery/anterior inferior cerebellar artery, and posterior inferior cerebellar artery. The mean maximum diameter of the malformations was 7.2 ± 5.0 mm (range 3–16 mm). Four lesions had focal aneurysms associated with the pure arterial malformation, and 5 were partially calcified. In no cases was there associated intracranial hemorrhage or infarction. One patient underwent treatment for the pure arterial malformation. All 12 patients had follow-up (mean 29 months, median 19 months), and there were no cases of disability, stroke, or hemorrhage.CONCLUSIONSPure arterial malformations are rare lesions that are often detected incidentally and probably have a benign natural history. These lesions can affect any of the intracranial arteries and are likely best managed conservatively.
