ABSTRACT
Rasmussen's encephalitis (RE) is a rare progressive inflammatory disease of the central nervous system. It is characterized by unilateral hemispheric atrophy, pharmacoresistant focal seizures, and progressive neurological deficit. The exact etiopathogenesis still remains unknown. Brain imaging plays an important role in diagnosis and follow-up. Fluctuation of lesions in brain imaging was reported in few cases. We report the case of a 12-year-old boy initially with intellectual development disorders presented to the pediatric emergency department with complaints of multiple episodes of seizures resistant to treatment. The MRI showing typical aspects of Rasmussen's encephalitis.

ABSTRACT
Melanoma is a potentially fatal form of skin cancer. Although it's the most common type of skin cancer in the pediatric population, it's rare, affecting around 0.4% of patients under the age of 20. We report a case of cutaneous melanoma in a 10-year-old female patient. At 48 days of age, he had presented with a nevus on the scalp, immunohistochemical analysis was in favor of a dysplastic nevus, the patient was lost to follow-up, he presented after 10 years with a voluminous mass on the scalp, which required brain MRI to objectify its extent, the signal was in favor of a melanoma. The patient also benefited from a cervico-thoraco-abdomino-pelvic CT scan, which came back without any notable abnormality.

ABSTRACT
Aim: Magnetic resonance imaging is the most sensitive imaging technique for the detection of breast cancer, although it is rarely requested as a first-line procedure. The aim of our study was to determine the indications and results of breast examinations using 1.5 Tesla MRI in a referral imaging centre in Douala. Methodology: We conducted a retrospective descriptive cross-sectional study between 01 March 2021 and 31 December 2022. The examinations were performed with a dedicated breast scanner, using axial and sagittal T1 SE and T2 FSE sequences, as well as dynamic T1 sequences with gadolinium injection, and interpreted by two experienced radiologists. According to the BIRADS classification of the American College of Radiology (ACR), examinations graded 4 to 5 were considered positive. Results: Thirty-five patients underwent breast MRI, with a median age of 47, ranging from 29 to 65 years. The vast majority of prescribers were gynaecologists (88.6%). The most common indication for MRI was for additional assessment of a lesion (34.2%), followed by assessment of locoregional extension (17.1%), particularly for multiple extensions. All investigations requested solely for mastodynia (14.3%) were unremarkable. The two cases of investigation of breast discharge were mainly associated with enhancement without mass (5.7%). At the end of the study, 28.5% of MRI scans were pathological according to BIRADS. Conclusion: The gradual introduction of 1.5 T MRI scanners in our environment means that we can now carry out breast MRI scans that are much more sensitive than ultrasound mammography. However, prescriptions are still highly specialised, and indications need to be verified, given their relative specificity and the socio-economic context in which our countries are evolving.

ABSTRACT
We report the case of a 30-year-old female patient, G2P1001, presenting initially with headache, followed by tonic-clonic seizures tonic-clonic seizures on postoperative day 5 of an elective caesarean section indicated for transverse position, and performed after epidural anaesthesia. A cerebral revealed engorgement of the sagittal venous plexuses, and suggested the diagnosis ofthe diagnosis of intracranial hypotension. Management was multidisciplinary, including anti-epileptic treatment, analgesics and an epidural blood patch, leading to a favourable outcome.

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
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
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.
