Background Moyamoya disease (MMD) can be a major cause of hemorrhagic stroke. Though extensive angiographic studies have been undertaken, the understanding of the association between aneurysms and MMD remains unanswered. In this study, we explore the association of the aneurysm with MMD and its management. We have also reviewed such associations described in the literature and how the present cases differ from those previously described. Materials and methods The clinical and radiologic data of moyamoya disease cases were accessed from medical and radiological records between January 2010 and July 2017. Two neuroradiologists independently analyzed the data and imaging details. Results Out of 103 patients with MMD, eight patients (7.77%) had associated intracranial aneurysms with eleven aneurysms. Out of the 11 aneurysms, five were the tip of the basilar artery aneurysms and were the most common location for aneurysm (45.5%), followed by lenticulostriate artery, PCA perforator, and distal ACA (DACA) in the P1 PCA, P2 PCA, and P3 PCA artery aneurysms. Out of eight patients, five (62.5%) had a hemorrhage on a non-contrast computed tomography (NCCT) scan of the brain, whereas three (37.5%) had an ischemic presentation. Out of 11 aneurysms, seven aneurysms, including three basilar tip aneurysms (unruptured) and one PCA perforator (ruptured), and three saccular PCA (P1, P2, and P3) (ruptured) were treated by endovascular coiling. Follow-up angiography showed stable aneurysmal occlusion except in one basilar tip, where recurrence was observed. Conclusions MMD-intracranial aneurysm is commonly observed in patients with intracranial hemorrhage and carries a higher risk of rupture. Therefore, identification of the aneurysm is essential for management. Endovascular treatment, either with coil or glue embolization, can be a safe and effective treatment method for such aneurysms with long-term good results., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Phuyal et al.)

Objective: We aim to correlate the prevalence of symptoms of the lateral medullary syndrome (LMS) based on radiological classification., Methods: A five-year record of 41 patients diagnosed with LMS and admitted to a tertiary care center in Nepal was reviewed. We used chi-square tests to compare symptoms between rostral and caudal groups and different horizontal subtypes., Results: The subtype prevalence in the horizontal classification of LMS was large (31.7%), lateral (22%), dorsal (19.5%), typical (14.6%), and ventral (12.2%). The most common symptoms in the typical subtype of the horizontal classification were: pain/temperature loss in the contralateral body (7.3%) and dysphagia (7.3%); in the ventral subtype, swaying on the Romberg test (12.2%), dysarthria (9.8%) and dizziness (9.8%); in the dorsal subtype, headache (12.2%) and vomiting (12.2%). Whereas headache (22.2%) and lateropulsion on standing (14.6%), swaying on the Romberg test (14.6%), nausea/vomiting (14.6%) were common in the large subtype, and nausea/vomiting (19.5%) and headache (17.1%) in the lateral subtypes. Whereas, in rostrocaudal classification, the rostral subtype (61%) was more common than the caudal subtype (31%). There was no significant variation in symptoms based on the rostrocaudal classification of LMS., Conclusion: The common clinical manifestations are different for different radiological subtypes of LMS. Further comprehensive studies are essential to understand the prevalence of symptoms in different radiological subtypes and the clinical-radiologic correlation in LMS., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Shrestha et al.)
