Background: This study aimed to describe the results of mammography done during breast cancer awareness campaigns in Lomé. Methods: This was a retrospective multicenter study which focused on the analysis of mammographic examinations, with or without breast ultrasound, carried out in three (3) clinics in Lomé over a period of five (5) years during the breast cancer awareness month (Pink October) campaigns. We included in our study women of all ages who underwent a mammography during the study period. Additional ultrasound was performed as needed in some women to better characterize a lesion. The parameters studied were socio-demographic data, and aspects of breast lesions. We classified the lesions in order of severity according to the BI-RADS classification. Results: During the study we counted one thousand and seventy-four (1074) women who underwent mammography examinations, corresponding to an average of 214.8 women per year. The median age of the women was 46 years. The most represented age group was 40 - 49, constituting 30% of cases. Mammography was performed on all women and ultrasound was performed on 51.3% of women. Lesions suspicious for malignancy (BI-RADS IV) and lesions highly suggestive of malignancy (BI-RADS V) represented 3.5% and 1.9% of cases respectively, amounting to a prevalence of 5.4%. They occurred more frequently from the age of 30 years with a statistically significant difference (p = 0.02). These lesions could be identified on mammograms as masses with irregular shapes and spiculated margins representing 16.1% and 9.7% of masses respectively. On ultrasound, these were solid masses with irregular and ill-defined borders, representing 25.2% and 5.2% of solid masses respectively. Lesions suspicious for malignancy were most often found in the UOQ (upper outer quadrant) in 70% of cases. Conclusion: Mammography screening for breast cancer remains a necessity in our comm

Background: Ultrasound has become the most widely practiced medical imaging examination even in developing countries because of its non-irradiating, non-invasive nature and its relatively affordable cost. Objective: The objective of this study was to review the practice of medical ultrasound in Lomé city. We carried out a descriptive cross-sectional study using the pre-established fact sheets. It took place from 16 August to 30 November 2013 in the healthcare facilities of the city of Lomé. Results: A total of 47 centers were surveyed, including 14 public centers and 33 private centers. The ultrasound scanners were mostly acquired in the new state (59.6%) with only 34.1% of these ultrasound scanners equipped with the Doppler mode. There were 3 ultrasound scanners (6.4%) that had a 3D probe. Radiologists were the ones who carried out most of the ultrasound examinations in public centers, while in private they accounted for half of the performers (45.5%). Physicians enrolled in a specialty in radiology played a significant role in these private structures, accounting for 24.2% of performers. Cardiac ultrasound was performed only in 2 centers (4.2%). The ultrasound report was available in all public centers using the pre-established and standardized forms. The qualification of sonographers and the status of ultrasound scanners are relatively acceptable. Conclusion: Ultrasound scanners were mostly acquired in new condition. Radiologists remained the ones who carried out the largest number of ultrasound examination in Lomé.

Background: Radiology in elderly as pediatric radiology poses a number of problems. The normal radiological appearance of the elderly patient’s chest is very varied and the changes are ubiquitous. Purpose: To describe the computed tomography profile of the elderly subject’s chest. Materials and Methods: Descriptive prospective study from January 1st to June 30th, 2018 carried out at the University Campus Hospital of Lomé. Results: We recorded 64 chest CT scans. The average age of the patients was 71.3. Internists (n = 21, 32.8%) and general practitioner (n = 16, 25%) were the major applicants for these tests. In most cases, thoracic CT examinations were requested as part of an extension assessment (n = 21, 32.8%), dyspnea and pneumonitis in 18.8% of cases each. All thoracic CT examinations were performed with contrast injection. CT with the TAP protocol was the most observed, accounted for more than half of the exams (56%). The main pathological lesions observed were diffuse parenchymal lesions (39.5%), pleurisy (11.1%) and PAH (11.1%). Conclusion: Computed tomography occupies an important place in the care of the elderly but the actors involved in their care must be trained to take optimal care.

Breast cancer represents a real public health problem due to its increasing frequency, its seriousness and its psycho-social implications. The aims of this study were to determine the level of awareness of women on the performance of mammography in the diagnosis and screening for breast cancer. This was a cross-sectional study over a period of 4 months (from October 1, 2016 to January 31, 2017) in Togo. It consisted in completing a questionnaire distributed to women above 30 years of age. The mean age of the women was 42 years. 88.8% of them had heard of breast cancer. There was a link between age, occupation, level of education and awareness of breast cancer. Only 20.8% of women had heard of mammography, with a link between awareness of mammography and age, occupation, and level of education. A link was noted between awareness of breast cancer and awareness of mammography. Information on mammographic breast cancer screening is inadequate in Togo.

Background: Core needle biopsy (CNB) under ultrasound guidance is an accepted standard of care for the diagnosis of breast lesions. It is safe, cost-effective and minimally invasive compared with surgical excision. Objective: The aim of this study was to evaluate the CNB’s results regarding the procedure, complications, histopathological findings and their correlation with the imaging data and surgical histopathological findings. Method: A cross-sectional prospective and descriptive study of a consecutive series of ultrasound-guided CNB of breast lesions in women conduced from January 2015 to December 2016 at the Sylvanus Olympio university hospital of Lomé, in Togo. Results: There were 72 CNB performed under ultrasound guidance in women;from which 54 were retained for the study. The mean age was 44.9 years ± 9.8. 11.1% had a family history of breast cancer. Lesions were most often palpable (90.7%). They were located in the left breast in 54.7%. Lesions were categorized probably malignant or malignant (Birads 4 and 5) in 70.4% and probably benign (Birads 3) in 29.6%. Their mean size was 24.8 mm ± 7.6 at ultrasound. There were no major complications during the procedure. One CNB (1.9%) considered inconclusive was repeated. Histologically, invasive ductal carcinoma (61.1%) was the most common lesion. Fifty-three women underwent surgical procedure and histopathological confirmation. Ultrasound-guided CNB had a sensitivity of 97.5%, specificity of 100%, positive predictive value of 100%, negative predictive value of 92.8%, and an overall diagnostic accuracy of 98.1%. Breast Imaging Reporting and Data System (Birads) categorization had a sensitivity of 94.8%, specificity of 100%, positive predictive value of 100%, negative predictive value of 87.4%, and diagnostic accuracy of 96.2%. Conclusion: Ultrasound guided CNB represent accurate methods for the characterization of breast lesions, with high values of diagnostic accuracy, sensitivity, specificity and negative predict

Cancer is common in our setting and represents a real public health concern in sub-Saharan Africa. This work aimed to assess the role of computed tomography in the follow-up of patients treated for cancer in Togo. This was a retrospective descriptive study carried out over a period of one year, on patients with cancer, treated in the medical oncology unit of CHU Sylvanus Olympio and having undergone at least two CT scans after cancer treatment. Computed tomography evaluation was performed according to the RECIST 1.1 guidelines. We had found 46 patients. The mean age of the patients was 54.22 years with a female predominance (sex ratio 1:2.5). Cancers mainly involved the urogenital system (60.8%) followed by the digestive system (28.3%). Carcinoma represented 93.5% of cases, mainly adenocarcinoma (45.7%). 74 target lesions were present at baseline, with 18.9% and 11.6% disappearing at the first and second assessments respectively. 36 non-target lesions were present at baseline, with 25% and 22.2% disappearing at the first and second assessments respectively. New lesions were found in the abdominal region in 54.5% of cases and in the thoracic region in 41.3% at the first and second assessments respectively. 58.7% of patients had a stable disease at the first assessment and 39.1% had progression at the second assessment. 50% of them had received chemotherapy in combination with surgery. Computed tomography using the RECIST 1.1 guidelines is a necessity in monitoring tumor extensions and in the follow-up of cancer patients.

Background: This study aimed to determine the level of continuing medical education (CME) of medical imaging technicians in French-speaking West Africa. Materials and methods: This opinion survey was administered to radiology technicians in French-speaking West Africa from 1st June to 31st October 2020, i.e. over a period of 5 months concerning their level of CME and their need for CME. Results: Out of 100 technicians, 69% were men. The mean age was 40 years, with extremes ranging from age 23 to age 57. The majority of technicians (64%) worked in the public sector and 78% had work experience of less than 11 years. Most technicians were holders of a Bachelor’s degree (73%). The types of CMEs they knew were congresses, seminars, and modular training in 46% of the cases. The most available CMEs were seminars (63%). All technicians agreed on the need for CME and 96% said it had an impact on the delivery of radiology services. Technicians who had received CME at least once represented 61%. For 90% of technicians, the specific CME sought was management in radiology (33.33%) and radiation protection (25.81%). Conclusion: The need for CME is increasingly indisputable to radiology technicians in French-speaking West Africa;however, it remains a luxury for them, due to its scarcity and its high cost.

Studies on the canal dimensions of the cervical spinal are rare in Africa. The aim of this study is to provide normal values of the cervical spinal canal and spinal cord dimensions of adult people in Togo. It was about a twelve-year prospective study conducted in the main Hospitals of Campus Teaching Hospital. This study involved people of more than 18 years who neither presented any clinical sign nor rachis defect. The distances measured were antero-posterior 1 (APD1) and inter-pedicular (IPD) of the cervical spinal canal, the antero-posterior 2 (APD2) and the transverse (TD) diameters of the cervical spinal cord, followed with APD2/APD1 (R1) and TD/IPD (R2) research reports. The mean age was 38 +/- 9.34 years old. The average of APD1 of the cervical spinal canal stood at 15.41 ± 0.55 mm, with a minimum of 10.48 ± 0.57 mm and a maximum of 25.00 ± 2.60 mm. The IPD average stood at 23.27 ± 1.67 mm with a minimal average of 13.68 ± 1.46 mm and a maximal average of 33.68 ± 1.46 mm. The average of DAP2 was 11.66 ± 0.66 mm, with a minimum of 10.7 ± 0.66 mm and a maximum of 12.77 ± 0.66 mm. The DT average stood at 15.55 ± 1.54 mm, with a minimal average of 14.03 ± 2.43 mm and a maximal average of 17.63 ± 1.82 mm. The ratio R1 (APD2/APD1) average was 0.80 ± 0.04, with a minimum of 0.76 ± 0.06 and a maximum of 0.85 ± 0.07. The ratio R2 (TD/IPD) average stood at 0.69 ± 0.14, with a minimum of 0.5 ± 0.12 and a maximum of 0.84 ± 0.08. The cervical spinal canal and the cervical spinal cord diameters in Togo are not significantly different from those described above.

Background: “Gossypiboma” or “textiloma” refers to accidental retention of textile material in an operated area of the body. Abdominal surgery is most often responsible for this complication. The purpose of our study was to describe the appearance of abdominal gossypibomas on computed tomography (CT) scan images. Materials and Methods: We conducted a retrospective study over ten years (from January 1, 2009 to December 31, 2018) at the Teaching University Hospital of Lomé. We collected all surgically confirmed cases of abdominal gossypibomas with abdominal CT scans. Results: Fifteen cases were compiled, with a sex-ratio of 0.36. The average age of the patients was 34 years. The initial surgery was emergent in nine of 15 cases, 11 of which consisted of gynecological interventions. The gossypiboma symptom incubation period was between 3 days and 3 years. A radiopaque marker was observed via CT scans in three of 15 cases. The gossypiboma appeared encapsulated and spongiform in six cases and cystic in seven cases. There were two cases where the gossypiboma migrated into hollow organs. Conclusion: Abdominal gossypibomas appear polymorphic on CT scans and should be considered in patients who present with an abdominal mass and a history of abdominal surgery, even for absent radiopaque markers.
