We report here a 44 years old woman admitted within our department for 04 days of severe back pain complicated rapidly of bilateral lower-limbs weakness and urinary retention. Neurological examination found a complete paraplegia (0/5 stergh), with incomplete sensory deficit below the T-10 level, bowel and bladder dysfunction, decreased deep and superficial reflex. MRI with different sequences showed a large epidural mass lesion with slightly high signal intensity on T1-weighted images and heterogeneous low signal intensity on T2-weighted images from T11 to L1 suggesting an epidural hematoma. She underwent an urgent total laminectomy from T11 to L1 following by a complete removal of a large dark and compact epidural hematoma compressing the spinal cord. Operatively, there’s no sign suggesting an AVM. Postoperative course was uneventful and she was discharged ten days after surgery with complete recovery.展开更多

Mainly reported in adulthood, it is fought to be a posterior fossa benign tumor. In this paper, we talk about a 64-year-old woman, following up for Parkinson’s disease presented in our department for 7 months’ history of headache and gait disturbance. MRI showed a right cerebellopontine angle (CPA) heterogeneous unlimited tumor mimicking an epidermoid cyst. She underwent a lateral suboccipital craniectomy procedure that permitted obtaining the whole gross total resection of this tumor. The histopathological diagnosis was a cerebellar liponeurocytoma. She was discharged from hospital the 8th day after surgery and was free of symptoms since 5 years.展开更多
