ABSTRACT
Cerebral infection by the protozoan toxoplasma gondii, especially in immunocompromised patients, with preferential cerebral involvement of the cortico-subcortical junction, the thalamus and the NGC. MRI with gadolinium injection plays a fundamental role in the positive diagnosis and the monitoring of patients under treatment.

ABSTRACT
Brucellar spondylodiscitis often develops insidiously, causing a diagnostic delay and exposing it to serious neurological complications. The clinical and radiological aspects are not specific. The lesion is often monofocal lumbar. Diagnostic certainty is based on serology and/or bacteriological proof. MRI is essential for early diagnosis, mapping of lesions and the search for possible complications.

ABSTRACT
Background: This study evaluated mammography performance at the Garoua Regional Hospital in Cameroon. Methodology: We conducted a descriptive cross-sectional design and a consecutive non-probabilistic sampling of 25 female patients. The data collection and analysis focused on patient identification, examination request, technique, success criteria, and diagnoses of mammography. The study also considered the ethical and regulatory aspects of the research. Results: The main results showed that mastodynia was the most common indication (44%), heterogeneous fatty was the most common breast density (36%), compression level was adequate in most cases (76%), image quality was poor due to blackening (72%), symmetry and nipple clearance were the least met success criteria (52% and 64%, respectively), normal and nodule were the most common diagnoses (36% and 24%, respectively), and ACR 4 was the most common classification (36%). Conclusion: The study aimed to improve mammography practice and patient care by identifying the factors that affected image quality and diagnostic accuracy.

ABSTRACT
Muscle MRI is a valuable aid in the positive and differential diagnosis of myopathy. We report the case of a patient in whom MRI made it possible to make the diagnosis, and we will report through this observation the MRI aspects of these pathological groups.

ABSTRACT
Recent data confirms breast cancer to be the leading cancer amongst women in sub-Saharan Africa and the second cause of cancer-related deaths. Screening and early diagnosis are the main pillars in the management of breast cancer in resource-limited settings. This study explored mammography utilization and challenges in a peripheral referral hospital in Cameroon. To achieve this aim, a hospital-based sequential explanatory mixed-methods study was conducted. Quantitative data was extracted from the mammography registry over a five-year period, after which in-depth interviews were conducted for some clients randomly selected from the registry. A total of 392 clients had a mammogram during the study period and all were females. The median age was 47 years (range: 20 to 73 years). There were 126 screening mammograms (32.14%; 95% confidence interval: 27.54 – 37.02%). The fear of a diagnosis of breast cancer was reported to be an important factor in getting a mammogram, but also deterred some who did not consider themselves able to afford for care in the event of such a diagnosis. Other important factors associated with obtaining a mammogram were the death of a relative, friend, colleague or acquaintance attributed to breast cancer. Many respondents did not know about mammography and its availability in the local reference hospital. These findings indicate low levels of awareness and under-utilization of mammography. Campaigns to educate and raise public awareness about breast cancer screening may be important to improve mammography uptake and increase the proportion of screening studies.

ABSTRACT
Close to three-quarters (70%) of all cases of cervical cancer occur in countries with a low human development index where the burden of infections with human papilloma virus is high and screening uptake is low. The aim of this study was to assess the burden of metastatic disease from cervical cancer and the pattern of spread in a sub-Saharan African population. We extracted data from reports of computed tomography scans of the thorax, abdomen and pelvis (CT-TAP) of patients with histologically proven cervical cancer from a prospectively collected cancer imaging database from July 2022 to February 2024. Independent statistical associations were performed using Fisher’s exact test whilst metastatic disease patterns were illustrated with a Sankey diagram. Data was extracted from 113 CT-TAP reports of patients. The mean age was 59.9 ± 12.21 (range: 38 to 84 years). There was reported local, regional or distant spread in 53 out of 103 (46.39%) patients. Four out of 8 (50.00%) baseline scans for staging reported tumor spread, against 49 out of 105 (46.67%) follow-up scans (p=0.570). Cancer spread was mostly local invasion than distant (59% vs. 41%). Parametrial invasion was reported in 41 cases (35.04%), followed by nodal tumor disease (32 cases; 27.35%) of which 75% was pelvic. Common sites for distant metastatic disease were the peritoneum (16 cases; 13.68%), spleen (12 cases; 10.26%) and pleurae (12 cases; 10.26%). Age-related trends in the occurrence of metastatic disease was significant with a peak at 40 to 49 years (p=0.001). The high burden of cervical cancer spread suggests the need to intensify primordial, primary and secondary prevention strategies.

ABSTRACT
The concern about ionizing radiation exposure of women of childbearing age or pregnant women is still relevant and CT scanning alone is a subject of interest as it is responsible for 58% of radiation exposure from medical x-rays. The objective of our survey was to evaluate the knowledge and practices of radiation protection of CT scan users in women of childbearing age in the city of Douala in Cameroun. This was a descriptive and cross-sectional study that was conducted over a period from October to December 2019, in two referral hospitals in the city of Douala. We interviewed 30 women of childbearing age, 15 medical imaging technicians, and 45 referring physicians. The majority of patients were relatively young with an average age of 33.3±9.6 years. The majority of the medical imaging technicians and the requesting physicians were young people (24 to 30 years old) with 40% and 44.4% respectively. The applicant physicians were mostly general practitioners (40%), and the average years of experience were 2.1±1.1 years. The level of knowledge of radiation protection of women of childbearing age, radiology technicians and requesting physicians was unsatisfactory with a rate of 25.5%, 48.1% and 48.6% respectively without influence of the level of education. At the end of our study, continuing education in radiation protection and the routine use of the guide to the proper use of imaging examinations were recommended.
