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.

Aim: To analyze the practice of skin grafting in the surgery department “B” of the CHU of Point “G” in Bamako. Patients and Methods: This was a retrospective and prospective study carried out between 1980 and 2014, covering all patients who underwent a skin graft and hospitalized. It covered all patients who underwent a skin transplant and were hospitalized in the department during the study period. Result: There were 50 patients including 25 women and 25 men. The mean age was 25.2 ± 19 years. The average duration of lesion evolution was 1 year. The lesions to be grafted were located in the lower limbs in 60%. The average area of substance loss was 13.2 cm2. The indication for skin graft was asked for loss of substance following scar bridles in 40%, ulcerative-necrotic wounds of infectious or traumatic origin (32%), malignant skin tumor (14%). In pathology, there were 5 cases of malignant melanoma and 2 cases of squamous cell carcinoma. Thin skin grafting was the most used technique (62%). The postoperative follow-ups were simple in 94%. There were 3 cases of graft necrosis. The average length of hospital stay was 28 days. The esthetic result was judged satisfactory in 84% of the cases (n = 42), average in 14% of the cases (n = 7) and unsatisfactory in 2% of the cases (n = 1). The sensitivity was good in 36 patients (72%), average in 12 patients (24%) and poor in 2 patients (4%). Conclusion: They mainly affect young people. The reduction of accidents on the public highway, good management of burn injuries, wounds and good hygiene of the population will considerably reduce the rate of its affections.

In this paper, we have used the static spherical symmetric metric. The parameter of the nonlinearity fields is included in the arbitrary function characterizing the interaction between the electromagnetic and scalar fields. Taking into account the own gravitational field of elementary particles, we have obtained exact static spherical symmetric solutions to the electromagnetic and scalar field equations of nonlinear induction. Considering all forms of the solution of Liouville equation, we proved that the metric functions are regular with localized energy density. Moreover, the total energy of the nonlinear induction fields is bounded and the total charge of the elementary particles has a finite value (soliton-like). In the flat space-time, soliton-like solutions exist.

Introduction: Penetrating head injuries are often due to human-to-human violence, mainly by firearms, those by stab are rare. CT is the exam of choice in the assessment of emergency lesions. We report three observations, all victims of knife assault during the brawl in order to clarify the contribution of DTM in the care. Observations: 1) Mr. I S, 21-year-old, student, was admitted with the hillside implanted in the skull. There were traces of blood on his face and clothes. There was no neurological deficit on examination. The CT scan performed showed the knife penetrating the vault of the skull at the left parietal level, up to 5 cm in the cerebral parenchyma with a minimal subdural and intracerebral hematoma;2) Mr. S C, 43-year-old, farmer, admitted with a large left fronto-temporo-parietal wound, bleeding and right hemiplegia. The CT scan performed showed a frontal linear fracture (with fronto-ethmoid hemosinus) and left temporoparietal with a parietal intraparenchymal hematoma and homolateral frontoparietal subdural hematoma;3) Mr. S B: 40 years old, driver, admitted with a parietal wound. The CT scan performed objectified a left parietal cortical hematoma in relation to a metallic foreign body (3000 HU) corresponding to the distal end of the knife penetrating the vault of the skull. They all underwent emergency surgery and received antibiotics and preventive serotherapy. The postoperative follow-up was simple, the follow-ups are without neurological sequelae. Conclusion: Head trauma by knife is rare, it results from inter-human violence. The lesion diagnosis is computed tomography. The prognosis depends on the severity.

Fortuitous Discovery of a Multifocal Enchondromatosis in a Case at the “Luxembourg” Hospital Center in Bamako

引用

Open Journal of Radiology 2022年第4期12卷 222-228页

作者： Mamoudou Camara Aboubacar Sidiki Keita Mahamane Mariko Toumin Camara Issa Cisse Aly Traore Souleymane Sanogo siaka sidibe Center for Medical Imaging Exploration and Diagnosis Gamal Abdel Nasser University Conakry Guinea Medical Imaging Department CHU Mother-Child “Luxembourg” Bamako Mali Medical Imaging Department North Franche Comté Hospital Trevenans France Internal Medicine Department Siguiri Prefectural Hospital Siguiri Guinea Hemodialysis Department of CHU Donka Conakry Guinea Medical Imaging Department CHU Point G Bamako Mali

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.

Aim: This study aimed at describing the anatomical variations of the external branch of the superior laryngeal nerve and at estimating the frequency of nerves at risk during the thyroid surgery. Methodology: We realized a forward-looking study from September, 2016 in May 31st, 2018 in the laboratory of anatomy of the Faculty of Medicine and Odontostomatology of Bamako in Mali. All the fresh anatomical subjects not carrying trauma and or a scar at the level of the previous region of the neck were held. The anatomical subjects were not included presenting a traumatic lesion and\or a scar of the previous region of the neck. Results: We realized 34 dissections of the external branch of the superior laryngeal nerve to 17 deathly subjects (11 men and 6 women with a sex-ratio of 1.8). The average age of the subjects was of 42 years (extremes: 18 and 70 years). Our study allowed highlighting in 100% of the cases, the external branch of the superior laryngeal nerve and the superior thyroid artery so to the right as to the left. On 34 dissected external branch of the superior laryngeal nerve, none had a previous route. However we found 28 nerves (82.4%) having a later route, stuck to the external face of the lower constrictor of the pharynx. These were not mixed with the superior thyroid artery and its branch of division and were situated outside the thyroid capsule. In 17.6% of the cases (6 cases), the nerve had a route mixed in the branch of the superior thyroid artery. These were found inside of the capsule (11.8% adhered to the artery and 5.8% crossed its branch of division). Conclusion: The risk of injury of the external laryngeal nerve during thyroid surgery procedure is never zero. It is more important on the left side.

Purpose: Our purpose was to describe the anatomy of the external branch of the upper laryngeal nerve and to estimate the frequency of nerves at risk during the total thyroidectomies sub. Methodology: We realized in the CHU Point G in Bamako a forward-looking study over a period going from September 1st, 2016 till December 31st, 2017. All the patients operated by thyroidectomies subtotals for mild goiters were included to whom a systematic location of the external branch of the superior laryngeal nerve in the space avascular of Reeve was realized. Cancers and other thyroid pathologies were not included. Results: We counted and operated 120 cases of mild goiters. The external branch of the superior laryngeal nerve was seen and dissected in 80.8%;it was not seen in 19.2%. According to the classification of Cernea: the type 2 was found in 80.8% of the cases with him under typical 2b in 47.5% and under type 2a in 40 (33.3%). The global frequency of lesion of the external branch of the upper laryngeal nerve was 10.8% at 9 patients among whom 6 who presented a BENLS of Type Ni. Conclusion: The external branch of the upper laryngeal nerve of type 2 presents a risk of wound because the surgeon treats the upper pedicle at the level of the critical centimeter place over the upper pole of the thyroid. The identification of the nerve during the thyroid surgery is the solution of choice.

Aim: To assess the epidemiological profile of intestinal obstructions at the Koutiala district hospital. Patients and Method: This was a prospective and descriptive study taking place from August 1, 2017 to April 30, 2020. The files of patients with acute intestinal obstruction in the general surgery department of the Koutiala district hospital were collected. In this study, patients operated on for acute intestinal obstruction were included. Non-operated patients were not included in the study. Result: The records of 65 patients operated on for acute intestinal obstruction were collected. The mean age was 32 ± 22 with extremes of 1 year and 94 years. 7 infants (10.8%) and 1 4-year-old child (1.5%) were identified. The 16 to 59 age group was more common. Males were the majority with 70.8% (n = 46). The sex ratio was 2.4. The rate of bowel obstruction in the general population in the circle was 8.1 cases per 100,000 population. According to provenance, patients came from inside the circle (rural areas) in 87.7% of the cases (n = 57) and from the city of Koutiala in 12.3% (n = 8). 33.9% of our patients had undergone laparotomy (n = 22). Patients consulted urgently in 93.8%. The etiologies are dominated by post-operative straps (33.8%) and volvulus (24.6%). We noted 12 cases of intestinal necrosis. Postoperative morbidity was 13.8% of cases (n = 9) and mortality of 6.1% of cases (n = 4). Conclusion: Bowel obstruction is one of the most frequent surgical emergencies in our circle. They most often affect young subjects and young adult males. The etiologies are dominated by the post-operative flanges. Complications remain elevated.

Introduction: The word “Teratoma” derives from the Greek word “teratos” including the meaning show. Teratoid tumors derived from the transformation of multipotent germ cells. They are composed of ectodermal, endodermic and mesodermal tissues in variable proportions;hence the term “embryonic tumor”. Objectives: We are reporting the case of a mature teratoma discovered in a young child whose delivery was vaginally performed. Through this case we put in diagnostic and therapeutic highlight and we made a literature review. Case report: Patient 17 months admitted for the anterior compartment mass associated with inspiratory dyspnea. No anomaly/abnormality was detected during the follow-up of the pregnancy. The Patient with dyspnea grade 2 was admitted according to Chevaleir-Jackson classification. No abnormalities of stature ponderal developments were noted. Surgery of excision was our therapeutic alternative. Through the pathological examination a mature teratoma was found. Conclusion: Teratoma is a rare condition. Proper management of mature teratoma helps to prevent recurrence.
