AI Article Synopsis
- A 33-year-old woman was misdiagnosed with a cerebrovascular or mental disorder before being correctly identified with basilar artery migraine.
- During her hospital stay, she experienced a loss of consciousness, prompting an emergency brain SPECT scan that revealed reduced cerebral blood flow in specific brain regions compared to the left side.
- A follow-up brain SPECT during a symptom-free period showed normal blood flow, confirming the diagnosis of basilar artery migraine due to reversible ischemia in the right basilar artery area.
Article Abstract
The authors present a case of basilar artery migraine in a 33-year-old woman who was initially misdiagnosed as having a cerebrovascular or mental disorder and subjected to MRI and cerebral angiography, which, however, did not show any pathologic findings. During admission to the university hospital, she lost consciousness. An emergency Tc-99m HMPAO brain SPECT showed a significant decrease of regional cerebral blood flow in the right temporal and occipital cortices, and right cerebellar hemisphere, where regional cerebral blood flow was decreased by 10-24% as compared to the left side. The second brain SPECT during a symptom-free phase showed the reversion of regional cerebral blood flow to normal in these areas. Basilar artery migraine was diagnosed by the finding of reversible ischemia in the territory of the right basilar artery on brain SPECT images and the clinical picture.

Instrumentation of C2 vertebra is considered the most difficult for young neurosurgeons and trainees due to its complex anatomical structures, variety of surgical approaches and techniques, and proximity to important neurovascular structures. Key points from a surgical perspective for midline posterior approach is described in the era of neuroradiological advancements. Computed tomography angiographies (CTAs) of a total of 92 patients were evaluated with special attention to the key findings for insertion of screws for craniovertebral junction (CVJ) fixations.

The current study performed a comprehensive assessment of blood supply in the cerebellum of dromedary camels. To the best of our knowledge, this study is the first to provide detailed information about the origins, routes, and complicated patterns of branching in the rostral and caudal cerebellar arteries of dromedary camels. In total, 55 heads from male dromedary camels aged 2-6 years were analyzed using advanced casting techniques.

Purpose: Few data are available on the causality of cerebral artery fenestration (CAF) triggering cerebral infarction (CI) and this study aims to identify representative morphological features that can indicate risks.
Methods: A cohort comprising 89 patients diagnosed with CAF were enrolled from a total of 9,986 cranial MR angiographies. These patients were categorized into Infarction Group ( = 55) and Control Group ( = 34) according to infarction events.

Background: While acute occlusion of the subclavian artery (SCA) proximal to the vertebral artery (VA) origin is an uncommon but recognized cause of embolic stroke, an occlusion distal to the VA is rare and can be easily overlooked.
Case Description: We describe the clinical presentation and evaluation of a previously healthy 56-year-old woman who experienced four life-threatening posterior circulation strokes within 1 month, three of which led to basilar artery (BA) occlusions requiring thrombectomies. Workup revealed an occlusion of the right SCA located less than 1 cm distal to the VA origin.
