The aim of this study was to clarify the interest of standard radiography in the management of Ollier’s disease. Observation: Enchondromas are benign lesions that may present on imaging with nonspecific features in children, and they are relatively large lesions, with frequent endosteal erosion and rare matrix mineralization. We report a case of predominantly right-sided multifocal enchondromatosis in a 5-year-old girl with no known medical history, diagnosed fortuitously on standard radiography during a trauma assessment and confirmed by histology. No sign of pain was noted after a 6-month follow-up. But the radiographic control noted signs of diffuse osteoarthritic remodeling in the surgical areas and early fusion of the growth cartilages. Conclusion: Ollier’s disease is rare, you have to know how to think about it in the face of fortuitous discoveries, especially at an early age. Enchondromas are benign lesions that may present on imaging with nonspecific features in children. In all cases, standard radiography is essential in the diagnosis and follow-up of Ollier’s disease.

Introduction: Retroperitoneal teratoma is a rare congenital tumour, representing only 1% to 10% of primary retroperitoneal tumors in children, far behind ovarian and testicular locations. There is a clear female predominance with a sex ratio of 3.4/1. The purpose of this study is to review the clinical manifestations, the mode of revelation of retroperitoneal teratoma, the diagnostic means and the anatomopathologic aspect of retroperitoneal teratoma, then to show the contribution and the limits of the various imaging examinations: ultrasound, CT and MRI in the diagnosis of retroperitoneal teratoma. Observation: We report the case of a mature retroperitoneal teratoma discovered in a 10-month-old male infant. The diagnosis evoked by ultrasound and abdominal CT was confirmed by histological study of the excised specimen. The postoperative evolution after 3 months was favorable in particular with no signs of recurrence. Conclusion: Retroperitoneal teratoma is a rare congenital tumour. The complete imaging assessment including ultrasound and computed tomography is necessary preoperatively in order to make the diagnosis and to clearly determine the relationship with the various organs. The anatomopathological study confirms the diagnosis of retroperitoneal teratoma. Tumor excision must be radical to avoid recurrence, which readily occurs in a malignant form. Even if the tumor appears benign, postoperative monitoring based on clinical, biological and radiological examination is essential.

The aim of our work was to establish the diagnostic difficulty of isolated nonspecific retroperitoneal congestive adenitis on medical imaging. Patient: This is a 27-year-old patient from a district located 660 km from Bamako with no known medical history or notion of travel. The onset of the disease dates back to 3 years marked by pain in the right hypochondrium and the epigastrium radiating to the back in the form of torsion, of medium intensity associated with periodic vomiting and jaundice. She was referred to the medical imaging department for pain in the right hypochondrium and cholestatic jaundice. The abdominal CT scan with and without contrast injection showed an oval retroperitoneal mass, with regular contours sitting behind the head of the pancreas and in front of the right kidney with its hypo-dense center of density equal to 23 HU measuring 44 × 28 mm, with a thick wall enhanced after injection of contrast product. It was associated with a distended gallbladder with a thin wall and hypo-dense content and a moderate dilation of the intrahepatic bile ducts. Following these examinations, the diagnostic hypothesis of cystic dilation of the common bile duct was retained. Surgery made it possible to cure the retroperitoneal lesion, discectomy of the gallbladder and biopsy of the lesions. The histological examination made it possible to make the diagnosis of isolated nonspecific reactive congestive adenitis. Conclusion: Isolated nonspecific congestive retropancreatic adenitis with a necrotic center poses a diagnostic problem for imaging in our environment because of its similarity to the bile duct cyst. This study, which is a very illustrative case, showed us a diagnostic discrepancy between the result of cross-sectional imaging and that of surgery and pathology.

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: Malformations of the excretory tract are abnormalities due to a disorder of embryogenesis. According to some authors, their frequency varies from 0.30 to 5.25 per 1000. The aim of this study was to highlight the CT uroscan aspect of pyelic bifidity with intravesical ureteral ectopic junction revealed by a urinary calculus and to explain the interest of CT uroscan in the management of urinary pathologies. Result: We report the observation of a 37-year-old overweight patient with a body mass index equal to 28, a history of surgery and extracorporeal litho-thipsis dating back 10 years. He was referred to the Imaging Department in the context of renal colic. The uroscanner made it possible to highlight a left pyelic bifidity associated with an ectopic abutment of the left ureter on the superolateral wall of the bladder, a calculation in the left ectopic ureteral meatus measured at 4 mm in axial diameter. He noted upstream of these lesions, a uretero-pyelo-calicielle dilation on double homolateral pyelon. On late cuts, a slight delay in left renal excretion was noted. The right kidney was also the site of a hyperdense calculation of 1257 HU density and measured 4 mm in transverse diameter with a non-obstructive appearance. Due to a lack of means, our patient was subjected to oral medication, hygiene and dietary rules and rigorous monitoring. Conclusion: At the end of this study, the uroscanner is presented as the reference examination to better explore urinary pathologies. At the same time, it makes it possible to carry out a study of the organs surrounding the urinary tract. Always think about the association of several urinary pathologies each time you see a patient for renal colic.

Aim: To screen hepatitis B and C in occupational setting. Methods: Cross-sectional study multicenter in 16 enterprises (one occupational exposure;5602 agents). Screening was preceded by information, sensibilisation and informed consenting physician labor, labor union and agents. Hepatitis B surface antigen (HBsAg) and antibodies anti-hepatitis C (Elisa, third generation) were tested in all. For those with HBsAg positive, this test was completed by IgM and IgG, anti HBc, HBeAg, antibodies anti HBe, transaminases and HBB DNA;for those with positive anti-VHC antibodies, test was completed by transaminases and VHC’s RNA. Results: Rate of participation was 76.2% (4268/5602 labors). HBsAg or hepatitis C antibodies were positives in 425 (9.9%) of cases (HBsAg positive: 8.48%;Hepatitis C Antibodies positives: 1.50%;both: 0.05%). In HBsAg positive, viral replication and cytolysis were seen respectively in 2.5 % and 18.2%. According with transaminases, serologic markers and viral load, immunotolerance, inactive and immuno active phase were suspected in 0.56%, 80.9% and 1.6% of cases. In hepatitis C antibodies positives persons, any had viral replication but cytolysis was observed in 33.3% (n = 21). HBsAg was significantively (p < 0.00001) higher in exposed occupational enterprise versus non-occupational setting (14.4% vs 7.8%). They were no differences (p = 0.71) about hepatitis C antibodies in the two setting (1.8% vs 1.7%). Conclusion: Prevalence of HBsAg and hepatitis C antibodies was high in occupational setting in hepatitis endemic country. It’s important to screen all of person in these setting with no consideration with blood exposed or not exposed enterprise.

Objective: To describe the CT findings and clinico-epidemiological aspects of coronavirus pulmonary lesions at the Radiology Department of Mother-Child Luxembourg’s Hospital in Bamako, West Africa. Materials and Method: This was a cross-sectional descriptive study over a period of three months (November 2020-January 2021). The study involved all patients with a clinical suspicion of COVID-19 or confirmed cases with suggestive CT scan lesions during this period. No patients without suggestive CT lesions were not included. The variables were age, sex, clinical data, lungs lesions on CT scan and their severity. Results: Out of 202 patients enlisted, the age group 52 - 63 years was more frequent (30.2%), i.e. an average age of 60.43 years (range 23 and 95 years). Men represented 56.4% or a sex ratio of 1.3. Cough was the most common clinical manifestations (26.7%). Major findings were mixed appearance of the lung lesions (45.5%). The peripheral distribution was 57.4% and the bilateral topography was 98%. These lesions were extensive in the majority of our patients with 28.2%. Conclusion: Older people dominated the socio-demographic profile of our series with a predominance of men. Cough was the most observed clinical information. Mixed lesions with peripheral and bilateral distribution dominated the semiological tomodensitometric aspects. By severity, extensive lung lesions were the most commonly observed.

Introduction: Spondylolisthesis is defined as a permanent anterior sliding of the vertebral body accompanied by the pedicles, the transverse processes and the posterior joints in relation to the underlying vertebra. The prevalence of spondylolisthesis varies between 4% and 9%, according to different authors in France, China and Japan. In Africa, some African authors find a spondylolisthesis rate of 9.93%. The objective of this study was to study the clinical and radiological aspects of spondylolisthesis at the Mother-Child Hospital of Bamako. Methods: Prospective and retrospective descriptive study carried out in the neurosurgery department of CH Mother-Child Luxembourg in Bamako from 2010 to 2018. Result: We collected 42 patients operated on for spondylolisthesis out of 145 patients, i.e., 29% of the department’s activities. The average age of our patients was 51 years old, with extremes of 20 and 75 years old. The sex ratio was 0.81 in favor of women. 61.9% of our patients performed work requiring physical strength. Neurogenic claudication was the predominant clinical sign with 88.1% of cases. CT was the most common way of exploration in 57.1% of cases and CT myelo in 47.6% of cases. Disc herniation was associated with spondylolisthesis in 23% of cases. Spondylolisthesis was grade 1 in 59.6% of cases and was responsible for mixed stenosis in 73.82% of cases. All our patients underwent laminectomy. The evolution at 6 months postoperative was favorable in 64.3% of cases. Conclusion: The diagnosis of spondylolisthesis is radiological and makes it possible to define the type of lesion according to its etiology and its severity, but also to highlight the conflicts with the nervous system which will have to be cured. Field and household work, pregnancy, carrying loads or children on the back could be incriminated.
