“…We also found that cerebral infarction constituted 63.1% of all cases examined with a CT scan, while haemorrhagic stroke comprising of ICH and SAH constituted 35.2%. This finding is in agreement with previous studies that reported a higher prevalence of ischemic than hemorrhagic stroke in sokoto north western Nigeria by Garba et al [31], South western Nigeria by Eze et al [32] and South south Nigeria by Onubiya et al [21]. On the other hand haemorrhagic stroke made up of more than 60% of all stroke in two studies in Ghana [33] and Tanzania.…”

Background: Stroke is a common neurological disorder associated with high morbidity and mortality worldwide. Aim: The study set out to characterize the clinico-radiologic pattern of stroke patients as well as to determine the correlation between the clinical and computed tomographic (CT) scan findings in a tertiary hospital in Makurdi, North central Nigeria. Method: This was a retrospective study of 145 patients with clinically suspected stroke, who underwent CT imaging at the

“…Characterization of CVA in ischemic or hemorrhagic was usually based only on clinical judgments, which are sometimes supplemented with some eponymous clinical scoring systems, such as Siriraj Stroke Score ( 15 ). The few CT-controlled reports on CVA in general in the SSA usually record a low CT rate for the patient cohorts ( 15 ), find sICH rates of 28–52% among their patients population ( 15 , 16 , 20 , 26 , 27 ), and usually fail to describe the intracranial distribution of the hemorrhage. The only other report known to us essaying, but not quite successfully at that, to specifically characterize the intracranial distribution of primary ICH from an indigenous SSA population was a post-mortem, not a CT-based study, and is somewhat dated ( 21 ).…”

The Clinical Epidemiology of Spontaneous ICH in a Sub-Sahara African Country in the CT Scan Era: A Neurosurgical In-Hospital Cross-Sectional Survey

BackgroundThere is paucity of data-driven scientific reports from sub-Saharan Africa on the burden of spontaneous intracerebral hemorrhage (sICH). We have maintained a prospective consecutive in-hospital database of cases of sICH referred for neurosurgical intervention over a 5-year period.MethodsThis is a cross-sectional descriptive study of the clinical epidemiology and brain computed tomography (CT) characterization of sICH from the database in this region in the current era.ResultsThere were 63 subjects, 38 (60.3%) males, aged 28–85 years, mean 55.7 (SD, 12.7), the modal age distribution being the sixth decade. Uncontrolled hypertension was the main predisposition in the study: present, premorbid, in 79%, but uncontrolled in 88% of these known cases, and exhibited malignant derangements of blood pressure in more than half. The clinical ictus to in-hospital presentation was delayed, median 72 h; was in severe clinical state in 70%, 57% was comatose; and was complicated with fever in 57% and respiratory morbidity in 55.6%. The main clinical symptomatology was hemiparesis, headache, vomiting, and aphasia. The sICH was supratentorial on brain CT in 90.5%, ganglionic in 50.8%, and thalamic in 58.3% of the latter. The bleed had CT evidence of mass effect and intraventricular extension (IVH) in more than half. Twenty-three patients (36.5%) underwent operative interventions.ConclusionIn this patient population, sICH is mainly ganglionic and thalamic in location with significant rate of associated IVH. In-hospital clinical presentation is delayed, and in a critical state, the bleeding is uncontrolled hypertension related in >95%.

“…A study by Yunusa et al, to determine the patterns of CT findings of the brain in stroke patients in Nigeria, found that the prevalence of stroke decreases with increasing age, especially after 40 years. 43 Some studies have reported that hypertension is the most frequent risk factor seen among patients with ischaemic stroke. 18,33 Their findings could be due to increased pain, psychological stress, urinary retention, elevated intracranial pressure and hypoxaemia.…”

Objective: To determine the Computed Tomography (CT) patterns of intracranial infarctsDesign: A retrospective cross-sectional study.Setting: The CT scan unit of the Radiology Department, Cape Coast Teaching Hospital (CCTH), from February 2017 to February 2021Participants: One thousand, one hundred and twenty-five patients with non-contrast head CT scan diagnosis of is-chaemic strokes, consecutively selected over the study period without any exclusionsMain outcome measures: Patterns of non-contrast head CT scan of ischaemic strokes.Results: About 50.6% of the study participants were females with an average age of 62.59±13.91 years. Males were affected with ischaemic strokes earlier than females (p<0.001). The risk factors considered were, hyperlipidaemia (59.5%), hypertension (49.0%), Type 2 diabetes mellitus (DM-2) (39.6%) and smoking (3.0%). The three commonest ischaemic stroke CT scan features were wedge-shaped hypodensity extending to the edge of the brain (62.8%), sulcal flattening/effacement (57.6%) and loss of grey-white matter differentiation (51.0%), which were all significantly as-sociated with hypertension. Small deep brain hypodensities, the rarest feature (2.2%), had no significant association with any of the risk factors considered in the study.Conclusion: Apart from the loss of grey-white matter differentiation, there was no significant association between the other CT scan features and sex. Generally, most of the risk factors and the CT scan features were significantly associated with increasing age.

Pattern of computerized tomography of the brain findings in stroke patients in Sokoto, northwestern Nigeria

Abstract: Cerebral infarction is the most common form of stroke in this study. CT is essential in establishing the type of stroke, which subsequently determines the type of intervention as well as follow-up evaluation the patient may require.
