Although it is essentially adult and elderly condition, stroke can occur in children. Their diagnosis essentially radiological is based on two main imaging modalities namely Computed Tomography (CT) and/or Magnetic Resonance Imaging (MRI). Our study aimed to study radiological features of stroke in children with an etiologic approach in three health facilities of Ouagadougou. Material and Method: We conducted a retrospective study with descriptive focus during 11-year period from January 1st, 2006 to September 1st, 2017 among children aged between 02 months and 16 years who underwent brain CT scan and/or MRI;in whom diagnosis of stroke had been established in radiology department of Yalgado Ouedraogo Teaching Hospital (CHU-YO), Schiphra Methodist Medical Center (CM Schipphra) and Saint Camille Hospital of Ouagadougou (HOSCO). Results: 40 cases of pediatric stroke were collected including 23 at HOSCO, 15 at CHU-YO and 03 at CM Schipphra. Mean age was 6.45 years, with extremes of 2 months and 192 months. Unilateral contralateral motor weakness was the most common clinical presentation (32.5%) followed by seizures (17.5%). Ischemic stroke dominated in 82.5% of cases. Sino-venous thrombosis was rare and suspected in only one case. Sylvian artery was mostly affected in ischemic stroke for 56.25% of patients. The main etiologic factors found were hematologic (67.50%) then infectious factors (25%). Sickle cell disease was always incriminated in hematologic factor. Homozygous SS patients were the most numerous (82%). Conclusion: Stroke diagnosis in children is based on etiologic investigation, biology with a major role of medical imaging. Sickle cell disease accounts a lot in occurrence of stroke in children in our context.展开更多

Methodology: Retrospective descriptive study conducted from January 2014 to October 2017. The included patients had an ultrasound-guided breast microbiopsy after a mammographic and ultrasound scan. The variables collected were gender, age, nodule size, ACR classification and anatomopathologic diagnosis. Results: 347 nodules were explored in 313 patients. There were 300 women (95.85%) and 13 men (4.15%), a gender ratio of 23.07. The average age was 44.64 ± 14.18 years. The average size of the nodules was 30.33 ± 19.58 mm. There were 53.89% ACR4 grade nodules, 48% ACR5 nodules and 32.28% ACR3 nodules. 86.49% of ACR3 nodules were benign and 97.92% of ACR5 nodules were actually malignant. Malignant tumors accounted for 50.29% of the nodules and were dominated by invasive breast carcinomas in 98.26%. The average age of patients with malignant tumors was 49.15 ± 11.55 years. 16% of patients with malignancy were aged under 40 years old. Conclusion: The diagnostic yield was satisfactory and there was a good correlation between the rate of malignant and benign lesions and the positive predictive values of malignancy in the literature.展开更多
