Résumé
Intradural lumbar disc herniation is a very complication of spinal degenerative processes with about 100 cases reported up to 1998. The mechanism of intradural disc herniation is unclear. Diagnosis of intradural lumbar disc herniation is difficult and seldom preoperatively suspected. A case of intradural lumbar disc herniation is reported. Clinical, neuroradiological and surgical findings are briefly discussed

Cervical disc herniation can be a cause of neurological symptoms but rarely Brown-Sequard syndrome. This syndrome is most commonly observed in association with spinal cord injury, tumoural disease or herniation of the spinal cord. Cervical disc herniation manifesting as a hemicord syndrome is a rare clinical finding. We report two patients, aged 45 and 52 years old, presenting with a unilateral right-sided hemiparesis with associated controlateral sensory findings at the T2 dermatome level. Magnetic resonance imaging demonstrated an isolated cervical disc herniation with marked spinal cord compression at C4/C5 and C5/C6 level respectively. Surgical treatment was performed by an anterior cervical discectomy with intersomatic arthrodesis in both cases. After surgery, there was a rapid improvement in motor symptoms and signs, however sensory functions required more recovery time. The previous 19 published cases were analyzed

to report a case of cerebellar mutism after surgery for posterior fossa tumour n a child. Mutism after posterior fossa surgery is a well described, although rare entity. Most of these tumours are located in the cerebellar vermis and/or extending to the hemispheres. The authors report a case of cerebellar mutism in a 9-year-old Moroccan boy who underwent surgical removal of a vermian medulloblastoma. The child became mute 24 hours postoperatively. He was fully alert without pyramidal signs and without lower cranial nerve palsies. His psychiatric examination was normal. The postoperative computed tomography images revealed nothing remarkable. He was mute for three weeks. Cerebellar mutism should be recognized as an important side effect of surgery
