Introduction: Cranioencephalic exploration has always played a major role in CT scans. In the Central Africa Republic (CAR), the lack of cross-sectional imaging before the year 2020 meant that no study had focused on cranioencephalic lesions. The aim of this study was to contribute to improving the management of cranioencephalic pathologies in CAR. Patients and Method: The study took place at the Bangui National Medical Imaging Centre (CNIMB). It was a retrospective study over a two-year period (March 1, 2021 to February 30, 2023). All patients referred for cranioencephalic CT scans were included, regardless of age or sex. Results: 1745 CT scans were performed, 575 of which were cranioencephalic CT scans. The majority of patients were male (53%). Most lived in the capital Bangui (90.9%). Patients aged 61 and over were the most representative. The distribution of patients by requesting department showed that the reception and emergency department was one of the least requesting departments. The main abnormalities observed were strokes, 82.1% of which were ischaemic strokes and 17.9% haemorrhagic strokes. Strokes were followed by degenerative lesions. Post-traumatic injuries included haemorrhagic contusions (38.3%), subdural haematomas in 20.5% of cases, and extradural haematomas (9.3%). Craniofacial lesions (fractures) were observed in 45.8% of cases. Conclusion: Cranioencephalic scans accounted for 1/3 of CT examinations performed during the study period. It revealed pathologies that could not be detected by conventional means. All in all, CT scans contributed to the diagnosis of cerebral pathologies.

Background: In Central African Republic, a study carried out in 2019 highlighted the limits of conventional radiography in the diagnosis of non-traumatic lower back pain in adults. Objective: The objective of this study is to show the value of CT scanning in the exploration of non-traumatic pathologies of the lumbar spine in adults. Patients and Method: Retrospective and descriptive cross-sectional study covering the files of patients aged at least 18 years old, sent for lumbar scanning from March 1 to December 31, 2021 at the medical imaging center. Results: In total, 593 scan examinations were performed including 159 (26.8%) examinations of the lumbar spine. The average age of the patients was 49.84 years. The majority were male (66%). 127 (79.8%) were referred mainly to the neurology and rheumatology departments. Common low back pain (n = 97, 61%) was the main reason for requesting a CT scan. The lumbar scan was performed without contrast product in 88.7% of cases. In total, 148 (93.1%) examinations were pathological and dominated by overall disc overhang (62.2%) and somatic and interapophyseal osteoarthritis (16.9%). The other lesions were spondylodiscitis (7.4%), tumor-like lesions (3.4%) and narrow lumbar canal (1.4%).

Objective: To describe the epidemiological, clinical, biological and morphological aspects of primary liver cancer (PLC). Patients and Methods: We conducted a 38-month cross-sectional study in the Department of hepatogas-troenterology and Internal Medicine “Amitié Sino-Centrafraine” University Hospital Center in Bangui. Included in the study were all patients with a diagnosis of PLC. The PLC’s diagnostic arguments were the large tumor liver associated or not with the elevation of alpha-fetoprotein, the heteronodular liver hypervascularized on abdominal ultrasound. Data analysis was done using epi Info 3.5.1 software. Results: We collected 115 cases of CPF among 2410 hospitalized patients (4.7%). There were 86 men and 29 women (sex ratio: 2.9). The average age was 50 years old. The main risk factors were alcohol consumption (72.2%) and chronic hepatitis B infection (67.4%). Frequent clinical signs were pain in the right hypochondrium and/or epigastric (93.86%), large tumor liver under examination (91.3%), weight loss (74.78%). The serum alpha-fetoprotein concentration was ≥ 400 ng/ml in 73% of the cases. The abdominal ultrasound found a heteronodular liver in all patients. The nodules were multiple hyperechoic in 66.1% of the cases. According to the Child-Pugh classification, the patients were classified as B (49.5%) and C (33.9%). The Okuda Classification ranked patients at stage 1 in 16.5% cases, stage 2 in 52.1% cases and stage 3 in 31.3% cases. According to the BCLC classification, 5.2% of patients were in stage A, 12.2% in stage B, 52.2 in stage C and 30.4% in stage D. Death was recorded during hospitalization in 89 cases (77.4%). Conclusion: CPF is a frequent and serious pathology in Bangui. Its diagnosis is often late, preventing curative treatment. The main causes are alcohol consumption and the hepatitis B virus. The population should be educated to reduce the incidence of this disease.

Introduction. - Tuberculosis associated with HIV-infection in children makes the diagnosis of tuberculosis more complicated since it is already difficult to establish because clinically based in low-income countries, and worsens its outcome under treatment. We report our experience from the paediatric clinics of Bangui, Central African Republic. Patients and methods. - Our retrospective study analyzed 18- month - to 15- year-old children treated for tuberculosis from April 1998 to June 2000. Diagnosis and outcome data were abstracted from patient medical reports and we compared seropositive and seronegative patients. Results. - Globally, 284 cases have been analyzed. HIV-inf-ection rate was 25.7% (95% CI: 20.7- 31.2% ). Pulmonary tuberculosis and mixed forms rates were 94.4% (N=268). extrapulmonary tuberculosis was essentially lymphadenopathies which have been restricted only to seronegative patients. Tuberculosis microbiological findings were significantly lower in seropositive patients compared with seronegative ones, for microscopy (8.2 vs 24.6% ) and for culture (35.6 vs 58.5% ) (P valueeropositive and 72 seronegative children for which outcomes were registered, mortality rate was higher in seropositive than in seronegative patients (57.1 vs 19.4% respectively, P e authors suggest that diagnosis of tuberculosis should be strengthened by blood or lymph node puncture culture particularly for HIV-infected children and that the treatment outcomes could be improved by diagnosis and treatment of other opportunistic infections.
