Aim of the Study: The aim is to analyse the epidemiological, clinical and CT aspects of hydrocephalus in children. Method: This was a cross-sectional descriptive study with retrospective collection from 1 June 2021 to 31 December 2022 within the radiology department of Charles De Gaulle Pediatric Teaching Hospital in Ouagadougou, Burkina Faso. The study included the records of patients with hydrocephalus who underwent cerebral computed tomography within this radiology department. Results: Hydrocephalus is due to a disorder of the hydrodynamics of the cerebrospinal fluid causing an increase in the volume allocated to this fluid in the brain and being accompanied by an increase in the pressure of this fluid. Its diagnosis is established by Doppler ultrasound or MRI prenatally, transfontanellar ultrasound in newborns and young children whose fontanel is permeable and by CT or MRI in older children, who can also determine the etiology. MRI remains an imaging technique that is less available and less accessible than CT in developing countries like ours. In Burkina Faso, MRI is only available in two private health facilities. The objective of this study was to describe the epidemiological, clinical and computed tomography aspects of hydrocephalus in children at the Charles de Gaulle pediatric teaching hospital in order to contribute to the diagnostic assessment and better management of this pathology. Over 19 months, 105 cases of hydrocephalus were recorded out of a total population of 115 children, or an average of 6 cases per month. The mean age was 17.52 months, with extremes of 03 days and 13 years, and the sex ratio was 1.38. Macrocrania, convulsions and psychomotor retardation were the main clinical signs, with rates of 49%, 34% and 30% respectively. On cerebral CT scan, hydrocephalus was triventricular (41.90%), tetraventricular (40%), and predominantly non-communicating (60%), with a mean Evans score of 0.53. The aetiologies were malformations in 34.28% of cases,

Objective: To describe the radiological and histological aspects of breast nodules among men in our practice setting. Methodology: This is a descriptive and retrospective study conducted from January 2014 to October 2017. The study included male patients with breast nodules classified ACR3, 4 or 5 after a mammographic and ultrasound scan. These lesions were explored through an ultrasound-guided breast microbiopsy. The following are the variables collected: age, family history of breast cancer, medical history, ACR classification, nodule size, and anatomopathologic diagnosis. Results: 13 breast nodules were explored among 13 male subjects. Mammography and breast ultrasound enabled to identify one ACR3 lesion, 10 ACR4 lesions and 2 ACR5 lesions. The average age was 56.53 ± 14.63 years and the average size of the nodules 28.91 ± 13.62 mm. As for histology, there were seven malignant tumors and six benign tumors. The average age of patients with malignancy was 61.45 ± 13.62 years. The malignant nodules average size was 29.45 ± 12.54 mm. Malignant tumors exclusively consisted of invasive breast carcinomas while Benign ones consisted of dystrophic and inflammatory lesions. Conclusion: Most often Breast lesions among men had an indeterminate appearance on imaging and were predominantly malignant in histopathology.

Melnick-Needles syndrome is an osteo-dysplasia caused by a mutation of a gene, FLNA, coding for filamine A. It is at the origin of a set of complex congenital malformations, mainly of interest to the members, but also to the cranio-facial region. Melnick-Needles syndrome was first described in 1966 by two Americans John Melnick, a radiologist, and Carl F Needles, a pediatrician. They described cases of families of several generations who had a characteristic severe congenital bone disorder. They thought that human-to-human transmission had occurred in one case. We report a case of Melnick-Needles syndrome which is a pathology with very high mortality especially in a male subject. This was an observational study of a case received in consultation with the pediatric service of the Souro Sanou University Hospital Center in Bobo Dioulasso in Burkina Faso. It was a 3-year-old boy born in a low-term pregnancy without any prenatal consultation, imaging test and prenatal biology performed. The exact pathogenesis of this condition is not established but is linked to a mutation of the Filamine A gene linked to sexual chromosomes X. Pathology is rare, around a hundred cases have been reported worldwide. Its incidence, according to the literature is around 1/100,000. The sex ratio is at 7. The malformations of this acquired embryo-fetopathy are multiple, polymorphic and asymmetrical. The diagnosis of this pathology is suspected by the clinic and established by molecular biology by sequencing the genes responsible for the mutation. However, imagery, in particular the scanner has a major role by its protocol with multi-planar reconstructions and its analysis in double windowing which allow a better description of the malformations of this syndrome. Its management is complex, and multidisciplinary, and the unfortunate prognosis in our context is because of the precarious technical platform. In our case despite the obvious malformations presented by the patient, the parents consult

Context: In spite of the development of cross-sectional medical imaging and endoscopy means, the prescription of specialized radiographic examinations is still relevant in the pediatric environment in our country. Objective: Show the contribution of specialized radiographic examinations performed in pediatric settings. Methodology: This was a retrospective descriptive study implemented over a five year-period, from June 10th, 2014 to June 10th, 2019 within the radiology department of Charles De Gaulle Pediatric Teaching Hospital in Ouagadougou. This study included the results of 192 specialized radiographic examinations collected within the concerned department. Results: The average age of the patients was 4.21 years with extremes of 8 days and 15 years. Infants (29 days to 24 months) were the predominant age group with a rate of 53.13% (n = 102 patients). Boys represented 76.51% of the sample with a sex ratio estimated at 3.25. Specialized radiographic examinations represented 0.46% of the overall imaging examinations and 0.72% of radiographic examinations performed during the study period. 67.19% of pathological examinations were reported. Colonic enema and retrograde urethrocystography (RUC) were the most performed examinations respectively accounting for 33.34% and 27.6%. The radiographic findings were consistent with the diagnostic hypotheses in 41.6% of cases. Conclusion: Specialized radiographic examinations keep their place in the exploration of several pathologies in pediatric settings.

Background: The assessment of liver fibrosis is an essential part of the fol-low-up of patients with chronic HBV. Ultrasound and fibroscan are two com-monly used non-invasive examinations and the purpose of this study is to as-sess the correlation between the results of these two examinations in the as-sessment of liver fibrosis. Methodology: This was a descriptive and analytical cross-sectional study with retrospective collection over a period of 30 months from January 01, 2018 to June 30, 2020 on the correlation between the ultra-sound aspects and the results of the fibroscan of patients with chronic carriers of Hepatitis B virus at the Teaching Hospital of Bogodogo and at the faith-based health center CANDAF. Results: A total of 85 patients with fibrosis were collected. The 30 - 40 age group was the most represented (41.18%), with a male predominance of 52.94%. The patients with a married life were the most represented (77.64%), the social stratum the most represented were the middle managers (32.94%). University level was predominant among educa-tion levels (45.64%). The personal history was traditional circumcision (34.12%), excision (21.18%), manicure (16.47%). The circumstances of the findings were blood donation (34.12%), screening (21.18%), fortuitous findings (16.47%). The association between echostructure and fibrosis on the fibroscan scan was significant (homogeneous hyperechoic echostructure p = 0.0028 and granular echostructure p = 0.0001). Fibrosis on scans had a significant associa-tion with liver contour (Regular contours p = 0.0009 and p = 0.0002). Fibrosis on CT scan had a significant association for the diagnosis of fibrosis on ultra-sound (p = 0.0002 for hepatic steatosis and cirrhosis and p = 0.0013 for hepat-ic dysmorphia), on the other hand, no significant association for hepatomegaly (p = 0.8883). Conclusion: Detecting the presence of fibrosis and monitoring its progression improves the management of patients with chronic liver disease. Ultr

Objective: To determine the diagnostic contribution of breast microbiopsy percutaneously under ultrasound guidance. 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.

Objective: To correlate the epidemiological and histological data of breast le-sions ACR 3, ACR 4 and ACR 5 biopsied on ultrasound in the city of Ouaga-dougou. Materials and methods: This was a retrospective study of data for 02 years (2015-2017) in the city of Ouagadougou. With the approval of the Ethics Committee for Health Research, the study focused on the histological results and radiological reports of biopsied lesions. Results: A total of 150 patients files had been collected. Breast lesions classified as ACR 4 were 50%, ACR 3 40% and ACR 5 10%. The risk factors were related to the ACR class. Ultra-sound was performed in all patients. The masses were the most common ele-mentary lesions found in breast imaging. On histology 98 lesions were benign, 16 intermediate lesions and 36 malignant lesions. Fibroids were the most common benign lesions of the ACR 3 and ACR 4 classes. Invasive ductal car-cinoma was the most common histologic type among malignant lesions in all ACR classes. Conclusion: Cancerous lesions are discovered late in our context. The ACR classification must always take into account discriminative ele-ments.

Purpose: The purpose of our study, which focused on the contribution of medical imaging in the diagnosis of urinary tract diseases in children at the Charles de Gaulle University Hospital of Ouagadougou, was to study the role of medical imaging in the diagnosis of urinary tract diseases in patients aged 15 years or less at the CHUP-CDG. Patients and Methods: This was a descriptive cross-sectional study with the retrospective collection covering the period from January 1, 2009 to December 31, 2018, i.e., 10 years. We collected a total of 833 medical imaging examinations, performed in 735 patients. The mean age of the patients was 40 months, infants accounted for 37.69% of the cases. Male patients were more numerous with a sex ratio of 1.53. Results: Ultrasonography was performed in 652 patients or 78.27%, ASP RX in 128 patients or 10.88%. URC and UIV were used in 6.53% and 0.68% of patients, respectively. CT and MRI were not performed in our study. The most frequent clinical urinary signs were dysuria (58.13%) and hematuria (43.94%). Ultrasonography was the most requested examination (78.27%), followed by conventional radiography (15.37%). Urinary lithiasis was by far the most common urinary condition (46.86%), followed by urinary tract infections (32.19%) and malformative uropathies (14.93%), of which the posterior urethral valve was the most frequent. Imaging was also used to find other conditions associated with urinary tract diseases. Conclusion: Medical imaging plays a major role in the diagnosis and management of urinary tract diseases in children. It has limitations, that is why a formal meeting between clinicians and radiologists is necessary for a better choice of imaging techniques and efficient management of these conditions.
