ABSTRACT
Background: Lately, there has been an increased utilization of computed tomography angiography (CTA) as the preferred first-line modality for the evaluation and diagnosis of most cerebral vascular lesions.Objective: The objective of this study was to evaluate suspected intracranial vascular cases, using CTA at a major referral tertiary hospital in South West Nigeria.Materials and Methods: This was a hospital-based retrospective study of suspected intracranial vascular cases in all ages and both sexes that had CTA from January 2011 to December 2018. Data were analyzed with IBM SPSS version 23.0, and P < 0.005 was considered statistically significant.Results: A total of 128 patients were studied, the mean age was 44.1 ± 17.7 years, and male: female ratio was 1:1.06. The leading clinical diagnoses were as follows: intracranial aneurysms (34/128), subarachnoid hemorrhage (27/128), intracranial vascular tumors (26/128), brain hemorrhage from vascular abnormality (19/128), and arteriovenous malformations (AVMs) (10/128). At CTA, 61 patients had vascular abnormalities: intracranial aneurysm was seen in 63.9% with a peak age range of 4160 years, and the leading location of aneurysms was posterior cerebral artery (18.8%), followed by posterior communicating artery (16.7%) and the cavernous segment of the internal carotid artery (16.7%). AVMs were more common in patients aged 40 years and below (91.7%) in males (66.7%) and in the parietal lobe. Intracranial aneurysms were 3.25 times as common as brain AVMs.Conclusion: Intracranial aneurysms are the predominant vascular lesions, occurring mostly in the older age group. AVMs occurred mostly in younger people, more in males, and predominantly in the parietal lobes. The hospital incidence of aneurysms to AVMs was 3.25:1

Introduction: Subarachnoid hemorrhage is a devastating neurological emergency associated with high mortality and disability. Little is known about its occurrence and clinical profile in Ethiopia. We, therefore, studied the clinical presentation, causes and outcome of the condition among in a tertiary facility.Methods: A retrospective analysis of records of patients admitted with the diagnosis of subarachnoid hemorrhage to Tikur Anbassa Specialized Hospital over a period of 12 years, January 2001 to January 2012, was undertaken.Results: Of 725 patients admitted with the diagnosis of stroke 52 (7.1%) patients were diagnosed to have subarachnoid hemorrhage. Death was registered in 18(34.6%) and disability in seven (13.4%).Hypertension was the most common risk factor, observed in 36 (69.21 %) of the patients, and seizure disorder and electrolyte abnormalities-hyponatremia were the most common complications. Conclusion: The outcome of subarachnoid hemorrhage in this study is comparable with reports from elsewhere. A prospective and well-designed epidemiological study is recommended. There is a need to improve the diagnostic and interventional capacity of the hospital

Les etiologies des hemorragies cerebro-meningees sont nombreuses et d'importance variable; mais les plus determinantes sont la prematurite; les traumatismes obstetricaux et l'hypoxie. Par ailleurs; il est difficile de tracer un tableau clinique propre a une hemorragie cerebro-meningee neo-natale; dans la mesure ou il se confond generalement au tableau clinique de toute souffrance du systeme nerveux central a cette tranche d'age. Neanmoins; le diagnostic d'une hemorragie cerebro-meningee merite toujours d'etre evoque chez un nouveau-ne; surtout premature

Les auteurs presentent l'observation d'un enfant de 11 ans chez qui une hemorragie meningee redicivante a amene a mettre en evidence un angiome caverneux; les conditions et moyens neuroradiologiques du diagnostic ont ete discutes. Ils insistent sur la necessite de toujours rechercher une cause organique aux hemorragies meningees chez l'enfant

Bleeding into the subarachnoid space (Subarachnoid Haemorrhage - SAH) is a dramatic and potentially fatal event that should not be missed. Modern trends have seen a decline in morbidity and mortality mainly due to advancements in neuroradiology and neurosurgical techniques coupled with early intervention. The review presents the problems faced in the past and highlights the developments in various aspects of this catastrophic disease whose morbidity and mortality remain unacceptably high despite the improvements
