We present the case of a 39-year-old patient admitted for a slow thoracic spinal cord compression syndrome associated with lumbar rachialgia. CT scan and MRI of the thoracic spine showed lysis of T4, T5, T6 and T7 vertebrae, an epiduritis and paravertebral abscesses. CT scan of the lumbar spine demonstrated osteolysis of the left iliac wing with skin invasion. This lesion infiltrated the sacrum and the body of L5. The iliac lesion was biopsied and the analysis revealed a granulomatous osteitis caused by Histoplasma duboisii. The treatment consisted of ketoconazole 400 mg daily for six months. Spinal decompressive surgery was not performed. Following antifungal treatment the patient had satisfying clinical and radiological outcome. After three years’ follow-up, the clinical course was uneventful. The patient had neither symptoms of spinal cord compression nor signs of further localizations.

We present our experience of microsurgical treatment of pericallosal artery aneurysms (PCAA) in three neurosurgical centers in Abidjan (Ivory Coast) from 1990 to 2016. This present study aimed to evaluate characteristics of 6 patients with PCAA treated during a 26-year period and to establish the rate, clinical nuances, anatomical variations and respective microsurgical approaches of PCAA in Abidjan. We analyzed medical files of all 93 patients admitted for an intracranial aneurysm between 1990 and 2016 and focused on the 6 patients who were treated for a PCCA. The mean age of patients was 37 years, half of whom were less than 30 years old. They were 3 men and 3 women. The time from first symptom to admission was more than 3 days, but less than 16 days. Five out of six patients had ruptured aneurysms and the clinical condition on admission was WFNS grade 0 one patient (16.67%) and WFNS I-III five patients (83.33%). Analysis of radiological data revealed Fischer grade IV three patients and Fischer grade I-II three patients. A total of 7 PCCA were recorded and they accounted for 6.19% of all intracranial aneurysms and 9.72% of all anterior circulation aneurysms. Six out of seven aneurysms (85.71%) were either smaller (2 - 6 mm) or middle sized (6 - 15 mm). There was only one (14.29%) giant PCA aneurysm (>25 mm). According to the location, two aneurysms (28.57%) were located on the A2 segment of the pericallosal artery (PCA) and five (71.43%) on the A3 segment of the artery. We found 4 cases of saccular aneurysms (57.14%) and 3 cases of fusiform aneurysms (42.86%), two of which were located on A2 segments of the 2 PCA on the same patient (16.67%). We didn’t find any PCA anatomical variation associated with any of the 7 aneurysms. Two patients developed perioperative rebleeding and in 1 case a severe preoperative hydrocephalus was diagnosed. The median time from rupture to surgery was 59.5 days with a range of 14 to 180 days. Treatment techniques included 4 clipping (57

Chronic subdural hematoma (CSDH) is one of the most common entities seen in neurosurgery. We report a case of infracallosal aneurysm revealed by CSDH in a 52 years old woman. She presented 3 days alteration of consciousness in 2019 and repeated in September 2020 a severe headache and dizziness. There was no history of others symptoms, nor head trauma. Routine blood examination and coagulation profile were normal. Emergency computed tomography (TC) showed a left temporoparietal-occipital CSDH. Cerebral Angio CT found a bilobated of A2 aneurysm. The precallosal interhemispheric approach was made and clipping the aneurysm after evacuation of CSDH without complication. CSDH is one of the revealed features of intracerebral aneurysm rupture.

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: 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

Background: Reported cases of knife injuries to the head in children are rare. Here we describe a case of pediatric penetrating brain injury by knife (PPBIK) and review literature. The patient’s parents were informed that non-identifying information from the case would be submitted for publication, and they provided consent. Case Presentation: A 3-year-old boy presented to our emergency department with a knife penetrating the front of his head during play. Neurologic examination was normal. Radiograph in lateral view demonstrated a metallic knife entering frontal bone. Computed tomography (CT) scan showed small hemorrhage around the foreign body recognized, accompanied by small pneumocephalus. The knife was surgically removed and the dura was closed. He was discharged home after the surgery with normal neurological status. Conclusion: Only four cases of PPBIK have been reported in the literature. The adequate management of these types of injuries requires a correct neuroradiological evaluation.

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.

Context: Cerebellar syndrome caused by disturbances of balance and coordination is not an uncommon neurological disorder. It has varied etiologies usually caused by tumor processes or suppurative collections. Vascular causes remain very rare, especially when it is a giant aneurysm of PICA representing 1% of intracranial aneurysms. Treating giant PICA aneurysms is a very difficult task for neurosurgeons because the surgical dissection can lead to severe damage due to the intimate relationship of PICA with the brainstem or nerve structures. We report a case of giant PICA aneurysm responsible for cerebellar syndrome successfully treated with surgery. The objective of this work is to draw the attention of practitioners to this unusual cause which can lead to diagnosis wandering and a lack of planning at the time of management. Case report: A 65 years old hypertensive patient was seen for a progressive disturbance of balance and walking disorder, but worsened in the last three months with no notion of fever. On admission, the patient was lucid, oriented in time and space and presented with static and kinetic cerebellar syndrome. Brain CT-scan without and with contrast revealed a tissular mass in the posterior fossa suggesting a tumor process, however, CT angiography showed a giant aneurysm of the PICA after reconstruction. A careful microdissection by a sub-occipital approach was decided. Opening the large cistern made it possible to visualize the aneurysm sack surrounded by a yellowish gliosis. The reclining and microdissection revealed the neck of the aneurysm, which was clipped to exclude the giant aneurysm in block. Postoperative follow-up was simple with progressive improvement in the cerebellar syndrome and walking over three months. Conclusion: Giant aneurysm of the PICA is rare. The localization in the posterior cerebral fossa can be confusing. Microsurgery gives a good result.

Introduction: Intracranial suppurations are neoformed purulent collections including, in decreasing order, cerebral abscesses, subdural empyemas and extradural empyemas. Otorhinolaryngologic infections are one of the main causes, especially in older children and adolescents. We report 3 clinical cases of endocranial suppurations treated at the Mali Hospital. Clinical Cases: 1) Observation 1. IK was a 14-year-old boy, who was hospitalized in our department for fever, headache and left hemiplegia. The emergency brain scan showed a right frontal and interhemispheric subdural empyema associated with multifocal sinusitis. Surgical drainage associated with ceftriaxone: 100 mg/Kg/d in direct intravenous (DI), metronidazole: 10 mg/Kgs/12hours in slow intravenous (SI) for 15 days, gentamycin: 3 mg/Kgs/d in SI for 3 days, paracetamol 15 mg/Kgs/6hours in SI, 10% glucose serum: 100 ml/Kg/d were given. The bacteriological analysis of the pus came back sterile. The postoperative period was calm. 2) Observation 2. This was a 14-year-old boy with a history of headaches who was admitted to our department for left hemiplegia. An emergency brain scan showed a right pre-suppurative encephalitis associated with a right fronto-ethmoidal and maxillary sinusitis. He was put on ceftriaxone 100 mg/kg/d in DI for 21 days, gentamycin: 3 mg/Kg/d in SI for 3 days;metronidazole: 10 mg/kg/12hours in SI for 21 days, paracetamol: 15 mg/kg/6hours in SI. After 3 weeks of medical treatment, a follow-up brain scan revealed an interhemispheric and right subdural empyema. Surgical drainage was associated with the triple antibiotic therapy initially instituted. The bacteriological analysis of the pus was sterile. The postoperative course was calm. 3) Observation 3. N.M was an 11-year-old boy, who was admitted with fever and left hemiplegi
