SLes shwannomes rachidiens sont des tumeurs bénignes qui représentent 30% des tumeurs rachidiennes. Ils se développent à partir des cellules de shwann des racines rachidiennes. Nous rapportons dans cet article l'expérience du service de neurochirurgie du CHU Hassan II de Fès dans la prise en charge des shwannomes rachidiens, du diagnostic aux modalités thérapeutiques sur une période de 13 ans. Les shwannomes rachidiens représentent 19,5% des cas de compression médullaire opéré durant la même période. L'âge moyen était de 45 ans avec une discrète prédominance féminine. La symptomatologie était insidieuse avec un délai de consultation en moyenne de 18 mois, elle est dominée par les douleurs rachidiennes et radiculaires. La moitié de nos patients avaient des déficits neurologiques. L'IRM médullaire a été réalisée chez tous nos patients. La localisation la plus fréquente était au niveau thoracique (40%). Soixante-deux pourcent des shwannomes étaient intra duraux, rarement extra duraux (8%), mixte dans 4%. L'exérèse chirurgicale était complète dans 96% avec recours à une ostéosynthèse dans deux cas et une arthrodèse dans un seul cas. L'étude histologique a confirmé le diagnostic de neurinome bénin dans 23 cas, un cas de shwannome malin et un cas de neurofibrome. L'évolution était favorable chez la majorité des cas, deux cas ont présenté des complications, une infection de la paroi et une aggravation neurologique. L'intérêt de ce travail est d'apprécier les caractéristiques de cette lésion et de comparer les résultats de notre série avec les données de la littérature.

Our institutionalexperience with Spinal Epidural Abscess. Nepal Journal of Neurosciences 2019 ; 16:16-19 in future citations. Abstract: Spinal epidural abscess is a rare pathology which is manifested by a classic triad of pain, fever and neurological deficit. In most cases, the clinical picture is incomplete which makes its diagnosis difficult. In this retrospective study, we report five cases of spinal epidural abscess treated in the neurosurgery department of Hassan II University Hospital of Fez. Four of our patients were admitted due to spinal cord compression, while one patient was admitted for isolated spinal syndrome without neurological deficit. Fever was present in all our patients, nevertheless no point of entry was identified in the initial assessment. MRI was performed on emergency basis in all of our patients which demonstrated an extra-dural hypo intensity on T1WI, hyper intensity on T2WI. It also showed lesions with peripheral enhancement after contrast with gadolinium. Four of our patients underwent surgical treatment which involved performing alaminectomy/laminotomy with drainage of the abscess, while one patient received medical treatment alone. The evolution was favorable in 4 of our patients while one patient died post operatively due to severe sepsis.
Pneumocephalus is the presence of air intracranially, this pathology is mostly seen in traumatic injury, however it remained exceptional in posterior spine surgery. In this study, we report a clinical case of a 66 years old woman who was operated for lumber spinal stenosis with spondylolisthesis presented a drowsiness, CT scan showed a compressive pneumocephalus (mount fuji sign) and pneumorrachis. A conservative treatment has been set up. The evolution was marked by improving its state of consciousness, the patient was discharged on day 10 post operatively with a brain CT that showed regression of PC.
Hassan II university hospital, for a cranial trauma following an assault by knife. The clinical assessment of the patient at his admission showed a conscious patient with a Glasgow score of 15, with no sensitive or motor deficit, hemodynamically stable with a normal respiratory function. The examination of the 12 pairs of cranial nerves showed a bilateral blindness with an amaurotic mydriasis. The local physical exam found a knife lodged in the right side of the occipital region (Figure 1-3).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
