Background: Cystic echinococcosis is a zoonotic infection that occurs worldwide. Humans are infected through ingestion of parasite eggs in contaminated food, water or through direct contact with infected dogs, which are the definite host. Humans serve accidentally as intermediate host, and occurrences are common in children and young adults. Cystic echinococcosis is endemic in Mediterranean, South American, Middle Eastern, Central Asia, East Africa countries and Australia. Multiple cerebral hydatid cysts are very rare with only a few reports in the literature. Case Description: We present the case of an 8-year-old girl who presented with focal seizures, hemiparesis, headache, vomiting and bilateral optic atrophy. Diagnostic workup was performed, and magnetic resonance imaging revealed multiple intracranial cysts predominantly in the right frontal region with significant mass effect. A total of 11 intracranial cysts were removed surgically, and the child recovered uneventfully. Conclusion: Neurosurgeons should keep hydatidosis in the list of differentials when evaluating patients with cystic diseases of the brain. Although the removal of such cysts is challenging, outcomes are excellent when cysts are evacuated without rupture and patients show complete resolution of symptoms.

Background: A number of meningeal neoplastic lesions may radiologically and clinically simulate meningioma, include hemangiopericytomas, solitary fibrous tumors, schwannomas, hematolymphoid lesions, metastases, and others very rarely, also may clinically mimic meningiomas. Case Description: We present the case of A 28-year-old male patient, with no notable medical history, who presented with worsening headaches for 3 months, imbalance, and visual deficits, An initial MRI revealed extra-axial lesion involving the right Parieto-occipital, The tumor was hypointense on T1-weighted MR images, hyperintense signals on T2-weightedMR images, and heterogeneously enhanced suggestive of a meningioma, total resection was achieved, and the histopathological analysis confirmed the diagnosis of an angioblastic meningioma. However, 15 months later, the patient presented with the same initial visual complaints. A subsequent MRI showed lesion recurrence, leading to a second surgical intervention. The histopathological analysis confirmed the diagnosis of an anaplastic xanthoastrocytoma. Conclusion: This represents an unusual location for an anaplastic pleomorphic xanthoastrocytoma, which should broaden the differential diagnosis of extra-axial lesions.

Introduction: A case of lumbar artery pseudo-aneurysm after surgery for lumbar vertebra burst fracture is presented. Only two cases secondary to spinal trauma and revealed after surgery have been described in the literature. A review of literature was conducted and a possible relationship with burst fracture or reduction maneuvers was discussed. Case Presentation: Here, we report a post traumatic lumbar burst facture with incomplete motor deficit of lower limbs after a fall. Surgical reduction and stabilization via posterior approach were performed. Post-operatively, a hemorrhage through surgical wound had been noticed. Pseudo-aneurysm of the lumbar artery at L3 level was diagnosed and embolisation was performed. Conclusion: This is a rare case of pseudo-aneurysm occurring in the setting of surgical stabilisation after a trauma. It was revealed by a hemorrhage discovered as a late complication. We should be aware of such potential complication as a delayed post surgery event in order to adapt the care.

托管安全业务：从被动监控到主动防御

由于故意的安全攻击所引起的网络服务宕机事件越来越频繁，这些事件以往则多半是由于系统故障所引起的。根据Gartner的调查报告，对于那些不采取主动安全防护措施的公司而言，由于软件系统故障所引起的系统宕机事件将在2008年增加至三倍。
