Hydrocephalus had been managed by ventriculoperitoneal shunt (VPS) or endoscopic third ventriculostomy (ETV) since several years. But these two different technics had some complications that must be managed promptly to avoid eventual fatal evolution. Chronic subdural hematomas after ETV is among these complications and is a very rarely situation observed in our department. This rare event associated with malaria in a child is considered to have a high mortality. Here we report a rare case of bilateral chronic subdural hematoma occurring in a 4-month-old boy after ETV and we discuss the likely pathogenesis and the difficulties of management.

Introduction: The left mesenterico-parietal hernia or left paraduodenal hernia is an anomaly of intestinal rotation which may be responsible for intestinal obstruction. It is rare. Observation: A 5-year-old boy was admitted for abdominal pain with episodes of vomiting and cessation of matters and gases. After clinical and paraclinical investigations, the diagnosis of occlusion was accepted and the child was operated. Exploration revealed a mesenterico-parietal hernia with a retrocolic sac measuring 11 cm of collar and a deep of 18 cm containing a twisted bowel. After reduction of the content, we untwisted the small intestine and released adhesions. The hernial sac was partially resected and the defect was closed. Operating outcomes were simple. Conclusion: The mesenterico-parietal hernia is a cause of organic intestinal obstruction. Although of congenital origin, it can have a late clinical manifestation. It should be considered in case of episodes of repetitive abdominal pain and vomiting to avoid complications.

Tuberculoma is a common condition in developing countries. In some cases, it may mimic a glial lesion, making differential diagnosis challenging. The authors report two cases of giant tuberculoma in young patients aged 14 and 16. A literature review was conducted on these cases. Both patients underwent partial excision. Histology concluded tuberculoma. Anti-tubercular treatment was implemented. The evolution one year later was marked by the persistence of neurological disorders, although they had improved.

Introduction: Gold panning is the research and artisanal exploitation of gold in the auriferous areas (rivers or others). Traumatisms arising from these activities are due to severe spinal cord injury and generally affect young people in full activity. They constitute a real social handicap in Mali and even in Africa. The aim of our study is to share our expertise in the management of these vertebro-medullary traumasin these miners who currently escape to all controls in Mali. Material and Methods: From 2013 to 2016, 76 Traumatic Spine Cord Injuries (TSCI) were treated in the department of Neurosurgery of “Hôpital du Mali”. There were 73 males (96.05%) versus 03 Females (3.95%), aged between 21 - 43 years old. Results: All of our patients were admitted with deficit differing from paraparesis to tetraplegia. According to Frankel scale, we found 59 patients with complete deficits (A grade, 77.63%), and incomplete deficits in 17 cases (12 grade B, 04 grade C, 01 grade D). The X-ray standard radiographies were done in 24 cases (31.58%) from which 02 patients had been operated with these data. CT scan centered on the injured spinal segment was performed in 74 cases (97.37%). The lumbar spine was affected in 39 cases, followed by thoracolumbar junction in 19 cases and thoracic spine in 16 cases. The cervical spine was only interested in two cases. Fractures dislocations are the most frequently lesions encountered in our series. The surgical approach was performed in 74 patients and 02 patients received conservative treatment. Conclusion: Traumatic Spinal Cord Injuries (TSCI) among miners are a real disaster in Mali and continue to plague thousands of families or increase the number of disabled people in our society. It is the only work, where the person concerned is making of his own grave. And according to witnesses, several miners remained at the bottom of the wells. Their prevention must first involve users by raising the awareness of local residents and traditio

Intraorbital mature teratoma is a rare congenital tumor of slow evolution that can compromise vision. Objectives: We describe the clinical and therapeutic aspects of a mature teratoma in childhood with a literature review. Clinical Case: It was a 12-year-old who had a progressive straight monocular exophthalmia with blindness. CT without and with contrast injection showed a double component intracolonic invasive tumor with partial contrast acquisition after injection. This tumor respected the bone walls of the orbit. The treatment was surgical by conjunctival dissection of the tumor and enucleation. This allowed the tumor to be fully excised under an operating microscope. The operating procedures were simple. Anatomopathology confirmed the nature of the tumor by visualizing the presence of a squamous epithelium by the high-magnification (X20) method of hematoxylin and eosin. Conclusion: Mature intraorbital teratoma is an embryonic tumor with early diagnosis the finding in an older child remains rare. Complete surgical excision allows healing.

Introduction: Extradural hematoma is a common pathology in our department. The natural history of small-volume hematoma is usually towards resorption. In rare cases, the hematoma calcifies and compresses the brain. We report an extradural hematoma in a 15-year-old boy who had a road traffic accident on February 2011. The brain CT-scan performed the following day revealed a small right frontal extradural hematoma. During hospitalization, he had a fever of 40 degrees with convulsions and the blood culture isolated the coagulase-negative staphylococci and Group D streptococci. When his conscience was restored, hemiparesis and dysarthria were observed. The control brain CT-scan performed 2 weeks after the trauma showed early resorption of the hematoma. Two months after the trauma, the brain CT-scan showed calcification of the hematoma. He underwent surgery in April 2011 to remove the calcification. The sequels were hemiparesis and posttraumatic epilepsy. Conclusion: The evolution of a small non-operated extradural hematoma can be done towards calcification thus requiring surgery.

Introduction: Rupture of intracranial aneurisms leads to severe morbidity and mortality. There are two modalities of treatment surgery and endovascular treatment. The diagnosis is made by angiography (DSA, CTA, RMA). The angiographic features used to assess the risk of the complications and choose the treatment modality are size, location and aneurism morphology. Materials and Methods: We reviewed and analyzed the computed tomographic angiography and magnetic resonance angiography of all patients admitted to the hospital of Mali with IAs from 2015 to 2021 either 7 years. Patients who were less than 18 years old, those with non-aneurysmal SAH, patients who request a discharge and those with an incomplete angiographic description of the IAs were excluded from the analysis. Results: We have collected 105 patients with 109 aneurysms. The sex ratio was 2/1 in favor of females. The mean age was 44.51 years with the range from 18 to 70 years. The presentation mode was subarachnoid hemorrhage (SAH) in 97% of cases. 76.19% had confirmed high blood pressure before the bleeding. 19.04% were diabetics. 98% of our patients have made a CT angiography and 2% have made MR angiography for the aneurysm diagnosis. 97.24% of aneurisms were located in the anterior part of the Willis circle. 39.44% of these aneurisms were the anterior communicating complex aneurysm. 27.52% of aneurysm had a small size, 42.20% had a medium size, 20.18% large size against 5.50% of the giant (Figure 3) and the middle cerebral artery was the most involved in the least. 95.41% of cases were saccular aneurysms against 4.59% fusiform. Conclusion: The angiographic feature of an intracranial aneurism in the Malian population may differ from other populations of the sub-region. The anterior communicating complex aneurysm is more common and the aneurism of the posterior part of the Willis circle is less common. We found the aneurism size ≥ 6 mm, ACA, MCA and Pcom more frequent.

Ritscher-Schinzel syndrome, or 3C (cranio-cerebello-cardiac) syndrome is a developmental disorder characterized by cranio-facial, cerebellar and cardiac anomalies. It is a rare disease with an incidence of 1/1,000,000 inhabitants, and was first described by Ritscher-Schinzel in 1987. 3C syndrome is an autosomal recessive disease caused by a mutation on the long arm of chromosome 8 to 8q24.13, the KIAA0196 locus, the strumpellin protein gene. The cardiac and cerebral anomalies are most often leading cause of death at an early age and people with 3C syndrome rarely exceed 40 years. In this paper, we report a case of Ritscher-Schinzel in 3-month-old boy who was admitted to our neurosurgical department in September 2020. Clinical examination revealed a macrocrania with head circumference at 47 cm. There was a prominence of forehead and occiput, the root of the nose which was flat, hypertelorism and micrognatism. The CT scan revealed Dandy WALKER malformation with cystic dilation of the 4th ventricle, an aplasia of the cerebellar vermis associated with a tretraventricular hydrocephalus.

Ewing’s sarcoma, a group of primary neuroectodermal tumor (PNET), is an uncommon rare highly malignant tumor mostly affecting the bones of male patients, and accounts for approximately 10% of the primary malignant bone tumors, and occupies the second place after osteosarcoma in children’s less than 20 years. Primary intramedullary Ewing’s sarcoma is an extremely rare condition. Here, we present a case of a 16-year-old girl with progressive weakness of lower extremities, inability to walk, progressive low back pain, bilateral leg pain, paresthesia and urinary retention. Spinal MRI showed intramedullary abnormal signal focus from T11 to L3 vertebrae with moderate heterogeneous enhancement on T1 weighted sequences. After surgery, histological examination found a lot of small round-cell tumors with a high nuclear-cytoplasmic ratio, frequent mitoses and apoptotic nuclei suggesting a diagnosis of Ewing’s sarcoma and confirmed by CD99 reactivity. She had undergone adjuvant chemotherapy and irradiation and was free of symptoms since 02 years. Within this single pure case of intramedullary Ewing’s sarcoma, perhaps the 1st in the English literature, the authors described this extremely rare uncommon localization with a brief review of the literature.
