RESUMO
We report here the case of a patient admitted for management of posterior fossa cerebral hemangioblastoma. A 16-year-old male patient with a history of intracranial hypertension syndrome consisting of progressively worsening headache, vomiting, especially morning and jet vomiting, and decreased visual acuity. The patient's symptomatology worsened a few days later with the appearance of a disturbance of balance with enlargement of the sustentation polygon. The patient initially benefited from a brain computed tomography (CT) scan that objectified a solidocystic process of the posterior brain fossa. The patient then underwent a surgical excision that was considered partial and the diagnosis of hemangioblastoma was made on the surgical specimen. Since the surgical removal was partial the patient was referred to our training where he received external radiotherapy on his hemangioblastoma of the posterior brain fossa. The patient was examined one month after the end of irradiation; he presented a spectacular improvement in his neurological symptomatology with a clear regression of balance disorders. The standard treatment for cerebellar hemangioblastoma is complete microsurgical removal, but our results show a high level of efficacy for fractional photon radiotherapy after partial surgery of this benign tumour.

We report the case of a patient with recurrent pterygo-palatal angiofibroma and its treatment. A 21-year-old male patient had a long history of recurrent epistaxis with progressive nasal obstruction. He was diagnosed with an angiofibroma centered in the right pterygo-palatine fossa. Initially, he underwent surgical excision with removal of the entire tumor. The evolution was clinically good with no signs of recurrence on the cervico-facial scan of control (CT). Nine months after, he presented a reappearance of epistaxis. A cervico-facial MRI was performed and showed a recurrence of the tumor process, which this time was considered inextirpable, hence the decision to opt for radiotherapy with intensity modulated radiation therapy (IMRT). He has improved clinically with a clear reduction in tumor mass on CT scan. This technique represents an interesting alternative to overcome anatomical complexity of the region, cover the tumor and preserve the organs at risk.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is an infectious disease caused by SARS-Cov-2, resulting in severe acute respiratory syndrome, with high potential of spreading and infecting humans worldwide. Since December 2019, when the virus was identified in humans, the literature on COVID-19 has grown exponentially and extrarespiratory symptoms including neurologic symptoms are increasingly highlighted. METHODS: Given the high and increasing number of publications reporting neurologic involvements of SARS-Cov-2, we thought that providing an update for neurologic complications of COVID-19 would be useful for physicians and especially young trainees in neurology and neurosurgery. Indeed, in this review we discuss several neurologic aspects reported in the literature to date including the evidence and pathways of neuroinvasion in COVID-19 and the main neurologic disorders reported in the literature to date, as well as future perspectives and the potential long-term consequence of current neuroinfection in COVID-19 patients. RESULTS: Currently, there is convincing evidence that SARS-CoV-2, the etiologic agent of COVID-19, can affect the nervous system, with damage and neurologic alterations. These neurologic disorders are grouped into several categories, ranging from nonspecific and moderate symptoms such as headache, myalgia, and hyposmia to severe symptoms including cerebrovascular disease and intracranial infections. Severe neurologic symptoms such as acute cerebrovascular disease occur only in a minority of patients with usual risk factors and are associated with poor outcome. However, most COVID-19 patients exhibit only minor or mild neurologic symptoms. CONCLUSIONS: Management of COVID-19 patients should include early clinical, radiologic, and laboratory neurologic assessment, with a close follow-up, especially in severe forms. Future studies should assess late and long-term consequences of current COVID-19 patients with neurologic involvement.
