The aim of this study was to report a case of multi-visceral sarcoidosis at the Mother-Child Hospital Center (CHME) “Le Luxembourg” in Bamako, Mali. Observation: This is a patient aged 62 at the time of consultation, a housewife, residing in the Banconi district, who was referred to us for thoracic-abdominopelvic imaging for chronic liver disease. After several diagnostic errors, the thoracic-abdominopelvic CT scan and liver MRI performed in our center showed, at the thoracoabdominal level, bilateral diffuse pulmonary micronodules and bilateral mediastinal-hilar lymphadenopathy;on the abdominal level, a dysmorphic liver with plaques of steatosis and a granular appearance of the liver parenchyma without periportal fibrosis. These imaging data combined with those from the liver nodule biopsy and biology confirmed the diagnosis of sarcoidosis type II. Treatment with corticosteroids gave satisfactory results and the patient recovered after 18 months. Clinical and CT monitoring 2 years from the start of the disease and 2 months from the end of treatment showed complete resolution of the lesions. Conclusion: The multi-visceral location of sarcoidosis is an entity whose diagnosis remains difficult;diagnostic and interventional imaging has an important place in its management.

Hemangioblastomas are benign vascular tumors of the brain. These are rare tumors, usually located in the cerebellum and most often affecting young adults. The aim was to study the value of CT in the management of hemangioblastoma through observation. We report the case of a 38-year-old patient referred to the radiology and Medical Imaging Department of the Marie Curie Medical Clinic in Bamako, Mali, for an orbito-cerebral CT scan in a context of bilateral eyelid edema. The examination was performed using multi-slice computed tomography (16 slices) with reconstruction in the 3 planes of space without and with the injection of an iodinated contrast agent. The CT scan was crucial in making the diagnosis of hemangioblastoma incidentally, which allowed for adequate management. The patient was operated on, and the radiological outcome was favorable, without significant cystic formation, after postoperative control and clinical signs were resolved. CT can be an interesting alternative in countries like ours despite MRI being the examination of choice in hemangioblastomas.

Introduction: Biometrics therefore corresponds to the measurement of the morphological elements of humans. One of the most common ultrasound requests by clinicians is the assessment of liver size. The aim of our study was to study liver biometry using ultrasound in healthy adult subjects. Material and Methods: This was a prospective, descriptive and analytical study, carried out at CHU Point-G over a period of 7 months. A liver ultrasound was performed on 100 individuals without lesions, by a doctor in his final year of specialization in radiology and medical imaging. For each subject, we determined the height and anteroposterior diameter of the right liver and the left liver. Results: The mean age was 39.05 ± 16.86 years. The body mass index (BMI) 18.5 - 24.9 group was the most represented with 58%. The mean height of the right liver was 138.40 ± 14.85 mm. It was 136.81 ± 14.70 mm in men and 139.92 ± 14.99 mm in women (P = 0.306). That of the left liver was 95.55 ± 14.34 mm, in men, it was 91.79 ± 13.51 mm and 99.16 ± 14.31 mm in women (P = 0.019). We found a significant correlation between right liver height and BMI (P = 0.013). Conclusion: The mean values of liver biometry were established in our series. There was a significant correlation between right liver height and BMI. Liver ultrasound remains a reliable technique for liver biometry.

Cashew tree has gradually moved from a purely ecological aspect to a socio-economic one, due to the marketing of its nuts. But production per area, estimated at between 424 and 547 kg/ha, remains low, in contrast to India (2nd largest producer) and Vietnam (3rd largest producer), whose yields range from 1000 to 1500 and 2000 to 2500 kg/ha respectively. This low yield is due to a number of factors, among which insect pests are the most damaging. Among these insects, termites are considered to be one of the main pests of cashew trees. The general objective of this study is to contribute to termite management through the use of bioinsecticides, an alternative to the use of chemicals in cashew orchards. Five (5) biological products were tested: Limocide, Carapa oil, Neem oil, Kitana and Kaskara. Among them, two products proved effective, with a mortality rate of over 50%. These were Limocide, whose LC50 was obtained in 24 h at a dose of 3.6 g/ml and 3.1 g/ml , giving a mortality rate of 57.66% ± 4.04% and 51.33 ± 2.08 respectively , and Carapa, at a dose of 4.5 g/ml, with an estimated mortality rate of 52.33% ± 1.52%. Such results have demonstrated the potential application of Limocide and Carapa biopesticides to sustainably control termites in cashew orchards of Côte d’Ivoire.

Introduction: Transcranial Doppler is a simple, non-invasive and inexpensive examination which allows the assessment of cerebral perfusion. In countries with limited resources, which do not have a means of monitoring intracranial pressure, this examination offers hope of survival for patients with traumatic brain injury. This study was designed to investigate the incidence of early cerebral circulation abnormalities after traumatic brain injury using transcranial Doppler (TCD). Methodology: A descriptive and analytical study was conducted over one year, including patients with traumatic brain injury and an initial Glasgow Coma Scale (GCS) score of less than 15. Non-inclusion criteria: Stroke, brain tumor, cerebral abscess. Exclusion criteria: Inadequate insonation window. Results: Out of 854 traumatic brain injury patients admitted to the emergency department, 112 were included in the study. The average age was 30.14 years, with a sex ratio of 4.1. Initially, 83.5% had moderate traumatic brain injury, and 12.1% had severe traumatic brain injury. Brain CT scans were performed in 95.7% of the patients. Edematous-hemorrhagic contusion was observed in 95% of the patients. On initial TCD, the pulsatility index in the middle cerebral artery was greater than 1.3 in 49.4% of the patients. Diastolic velocity was less than 20 cm/s in 46.4% of cases, and mean velocity was greater than 150 cm/s in 8.7% of cases. In this group, low diastolic velocity indicated cerebral hypoperfusion suggestive of intracranial hypertension. When the pulsatility index was greater than 1.9, no patient had a normal diastolic velocity. Among patients with severe traumatic brain injury, 61.5% had an abnormal pulsatility index compared to 42.3% of patients with moderate traumatic brain injury. Conclusion: TCD is a simple tool for analyzing intracerebral hemodynamics.

Introduction: Radiology and medical imaging examinations bring together the means of acquiring and restoring images of the human body from different physical phenomena such as the absorption of X-rays, nuclear magnetic resonance, reflection of ultrasound waves or radioactivity, with which we sometimes associate optical imaging techniques such as endoscopy. The objective of our study was to study the profile of radiological examinations in the radiology and medical imaging department of the “KALALE” medical clinic. Methodology: This was a descriptive, prospective study that took place over a period of six (6) months in the radiology and medical imaging department of the “KALALE” medical clinic and the centers of health of communes III and IV of Bamako in Mali. Data collection was carried out on a survey form. The parameters studied were sociodemographic data, clinical data, radiological data. Results: We recorded 6030 radiology examinations of which 19% of the examination frequency cases came from the “KALALE” medical clinic and 81% of the cases were referrals from the reference health centers of communes III and IV. There were 1500 X-rays or 24.9% of cases including 54% cases of bone X-rays;5% of cases of skull and face X-rays;5% of cases of Intravenous Urography (IVU);4% of cases of Hysterosalpingography (HSG);3% of cases of Retrograde Ureterocystography (UCR) and 1% of cases of X-ray of the Abdomen without preparation (ASP). We found 4530 ultrasounds or 75.1% of cases. Conclusion: Medical imaging has become essential in the study of the human body and now constitutes an essential tool for the detection and treatment of most pathologies, from simple fractures to the most serious tumors.

Intrasellar arachnoidocele is a herniation of the optochiasmatic cistern through a dehiscence of the sellar diaphragm producing an empty sella turcica, hence its name empty sella turcica syndrome. It is an extremely rare benign malformative pathology. We report a case of intra-sellar arachnoidocele in a 34-year-old woman revealed during an annual control of a sellar mass under dossinex by cerebral magnetic resonance imaging (MRI) which found the cystic formation of liquid signal identical to that of the LCS in hypo signal T1 and hyper signal T2 without enhancement after injection of Gadolinium. The epidemiological, clinical and radiological aspects of arachnoidocele were analyzed. The purpose of this work is to bring the interest of MRI in the management of this pathology.

作者： Ousmane Traore Ouncoumba Diarra Mamadou N’Diaye souleymane sanogo Ilias Guindo Abdoulaye Kone Hamady Sissoko Mahamadou Diallo Siaka Sidibe adama diaman keita Radiology Department of the Medical Clinic “Marie Curie” Bamako Mali Department of Radiology Center Hospital-University “Le Point G” Bamako Mali Radiology Department Commune III Reference Health Center of Bamako Bamako Mali Radiology Department of the Military Camp of Bamako Bamako Mali Department of Radiology Center Hospital-University “Le Luxembourg” Bamako Mali Radiology Department Center Hospital-University de Kati Bamako Mali Radiology Department of the Medical Clinic “Pasteur” Bamako Mali Department of Radiology Center Hospital-University “Gabriel Toure” Bamako Mali

Abdominal wall malformations correspond to a wide spectrum of congenital anomalies that are due to a defect in the closure of the anterior abdominal wall and can be fatal. We report the case of laparoschisis associated with a poly malformation syndrome in the same fetus at the reference health center of commune III of the district of Bamako. The objective is to clarify the interest of antenatal ultrasound in the diagnosis and prognosis of these malformations. It was a 19-year-old prim gravid woman received as part of the prenatal check-up. Antenatal ultrasound had allowed the diagnosis of malformation of the anterior abdominal wall of the gastroschisis type associated with abnormalities of the neural tube, the urogenital system and the bone skeleton. The antenatal diagnosis of the malformations had motivated the realization of a therapeutic termination of pregnancy at 19 weeks of amenorrhea and 3 days by triggering and vaginal delivery, allowing the confirmation of the diagnosis of gastroschisis and the poly malformation syndrome which is extremely rare. Antenatal ultrasound remains an ideal means of imaging for monitoring pregnancy and had made it possible to make the prognosis and antenatal diagnosis of multiple malformations in association, and to indicate better therapeutic decision-making.
