Many neurosurgeons consider cerebral aneurysms to be rare in Africa and the Middle East. In this report, we describe the pattern of cerebral aneurysms in Morocco and call into question the idea of their rarity in developing countries. Our objective is to urge neurosurgeons in these areas to track them and to treat them under better conditions. ⋯ Some data in this study (the delay between subarachnoid hemorrhage and admission, the high incidence of urban patients [80%], and the high rate of giant aneurysms) explain why many cases of ruptured aneurysms are not diagnosed. The analysis of our clinical series and the results of the epidemiological surveys show that the incidence has doubled every 5 years. These findings confirm that cerebral aneurysms are not rare in Morocco. A critical reading of the published articles claiming a low incidence of cerebral aneurysms in Africa, the Middle East, and Asia shows that this conclusion is not based on accurate and reliable statistical studies. Neurosurgeons in these regions should abandon this idea of rarity, and they should search for arterial cerebral aneurysms and develop the optimum conditions for the treatment of patients with aneurysms.

The goal of this study was to elucidate the pathophysiological features and treatment of hypertrophy of the posterior longitudinal ligament (HPLL) of the cervical spine. HPLL is defined as a pathological thickening of the posterior longitudinal ligament (PLL), causing spinal cord compression. Incomplete decompression via removal of only coexisting herniated intervertebral discs or spondylotic spurs might be performed, resulting in unsatisfactory surgical outcomes, when the PLL becomes abnormally thickened and contributes to myelopathy. ⋯ Patients with HPLL can benefit from an anterior approach with direct removal of the HPLL and associated herniated intervertebral discs or ossification of the PLL. Cervical polytomography, computed tomography, and magnetic resonance imaging are useful in establishing a diagnosis of HPLL.
