Orbital meningocele in two case studies.

BACKGROUND: Orbital meningocele is a rare congenital malformation characterized by herniation of the meninges into the orbit through a congenital defect in the orbital bones. Much less commonly, it occurs at the site of natural openings (e.g., optic foramen and sphenoidal fissure) or can be attributed to trauma. CASES DESCRIPTION: We report two patients with progressive proptosis found to have orbital meningoceles, respectively, attributed to congenital and traumatic lesions. The computed tomography scan in one case documented a traumatic orbital bony defect, but in the other case, led the mistaken diagnosis of an arachnoid cyst. CONCLUSION: Both patients underwent two operations each to ultimately achieve successful surgical correction of their respective traumatic and congenital orbital meningoceles.

Microsurgical Treatment of Ruptured Intracranial Aneurysms in Sub-Saharan Africa: A Series of 102 Consecutive Cases Treated in Senegal.

INTRODUCTION: In sub-Saharan Africa, the management of ruptured intracranial aneurysms (RIAs) is difficult for many reasons. In this retrospective, 3-year study, the authors will demonstrate the particularities of the management of RIAs in Senegal. METHODS: We analyzed retrospectively 102 consecutive cases of RIAs operated on between May 2013 and December 2016 in Neurosurgical Department of Fann Hospital in Dakar, Senegal. Patients characteristics, imaging results, aneurysms, treatment, and outcome were analyzed. RESULTS: One hundred two cases were operated in this 3-year period of a total of 129 cases of RIAs received in our department in the same period. A total of 65% of the patients were female. According to the World Federation of Neurosurgical Societies (WFNS) scale, 49% were WFNS I, and 33% WFNS III. Fisher scale showed 29% of Fisher 2 and 45% of Fisher 4. The aneurysms were located on anterior communicating complex in 38%, on the internal carotid artery in 28%, on the middle cerebral artery in 27% of cases and on posterior circulation in 9 cases. The pterional approach was used in 93 cases. According to the modified Rankin Scale, 67 patients (65.6%) had good outcome, 22 (21.5%) had poor outcome, and the mortality rate was 12.7% (13 patients) at last follow-up. CONCLUSIONS: This study demonstrates encouraging results if one refers to the global patient postoperative outcomes. However, the large number of patients not undergoing treatment also requires us to improve preoperative management conditions.

[Narrow lumbar channel due to epidural lipomatosis: case report and literature review]. / Canal lombaire étroit par lipomatose épidurale: à propos d'un cas et revue de la littérature.

Epidural lipomatosis is characterized by the abnormal accumulation of non-encapsulated grease in the epidural space. Although rare, it is a possible cause of lombosciatica or narrow lumbar channel. It is often associated with contributing factors such as prolonged corticosteroid therapy or obesity. We report the case of a patient presenting with disabling lombosciatalgias. Radiological evaluation confirmed the diagnosis of compressive epidural lipomatosis. Patient's evolution was favorable after surgical decompression.
