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.展开更多

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. <strong>Case Presentation:</strong> 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. <strong>Conclusion:</strong> 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.展开更多

Tremor, rigidity, and bradykinesia are the major symptoms of the disease. These motor impairments are often accompanied by affective and emotional dysfunctions which have been largely studied over the last decade. The aim of this study was to investigate emotional processing organization in the brain of patients with Parkinson's disease and to explore whether there are differences between recognition of different types of emotions in Parkinson's disease. We examined 18 patients with Parkinson's disease(8 men, 10 women) with no history of neurological or psychiatric comorbidities. All these patients underwent identical brain blood oxygenation level-dependent functional magnetic resonance imaging for emotion evaluation. Blood oxygenation level-dependent functional magnetic resonance imaging results revealed that the occipito-temporal cortices, insula, orbitofrontal cortex, basal ganglia, and parietal cortex which are involved in emotion processing, were activated during the functional control. Additionally, positive emotions activate larger volumes of the same anatomical entities than neutral and negative emotions. Results also revealed that Parkinson's disease associated with emotional disorders are increasingly recognized as disabling as classic motor symptoms. These findings help clinical physicians to recognize the emotional dysfunction of patients with Parkinson's disease.展开更多

We present 49-year-old man admitted with a chief complaint of tremor and balance problems for the past 2 months. He had ataxia on examination. Magnetic resonance imaging revealed a well circumscribed midline cystic lesion of the posterior fossa sharing the same signal characteristics as cerebrospinal fluid and non-communicating to the fourth ventricle. He underwent surgical treatment for his symptomatic posterior fossa arachnoid cyst with a good outcome at 2 years follow up.展开更多

[1], few cases have been published. We report an additional case of a 52-year-old right-handed man presented to the emergency department with evaluation of progressive severe intracranial hypertension and ataxia. His past medical history was unremarkable. His physical examination showed cerebellar syndromes. He underwent magnetic resonance imaging (MRI) which revealed a unique mass in the posterior fossa, lying within a cerebellar hemisphere. The patient underwent a suboccipital craniotomy for with a complete resection and samples were sent for histologic examination, showing closely packed, and round to oval cells. The nuclei had an irregular shape with clumps of heterochromatin. Lipid accumulation was a prominent feature of neoplastic cells. Postoperatively the patient did not receive fractionated radiotherapy. He is alive without deficit and with no evidence of recurrence on neuroimaging.展开更多

The aim of the present paper is to collect the reported clinical and radiological signs in the literature and compare it with a personal observation to evaluate the possibility of a presumptive diagnosis. A 4-year-old boy presented at the pediatric emergency department with 7 days history of severe headache, vomiting blurred vision and had one partial seizure. His neurologic examination was notable for decreased visual acuity with bilateral papilledema and intact extra-ocular muscles. His neck was rigid. Neuroimaging revealed a multifocal dural-based mass on the fronto-parietal convexity with dense heterogeneous contrast enhancement and hydrocephalus. He has undergone a Ventriculoperitoneal shunt and surgical excision of the mass the next day. Outcome was favorable with antituberculosis therapy and corticosteroids. The clinical presentation and outcome were similar to the reported cases in the literature.展开更多
