Role of magnetic resonance imaging in differentiating intrasellar cavernous hemangioma and pituitary adenoma: A case report-Decipit frons prima multos.

Background: Cavernous hemangioma represents a rare vascular malformation usually located in the cavernous sinus that could be exceptionally found purely in the intrasellar region. The clinical presentation of intrasellar cavernous hemangioma (ICH), frequently variable and unspecific, poses the patient at risk for misdiagnosis and the clinical consequences of suboptimal treatment. We present a case of ICH and describe the advanced magnetic resonance imaging (MRI) features that should direct toward the clinical suspicion of ICH.

Bow hunter's syndrome successfully treated with a posterior surgical decompression approach: A case report and review of literature.

Background: Bow hunter's syndrome (BHS) is a rare but surgically treatable cause of vertebrobasilar insufficiency due to dynamic rotational occlusion of the vertebral artery. Typically, patients present with posterior circulation transient ischaemic symptoms such as presyncope, syncope, vertigo, diplopia, and horizontal nystagmus, but irreversible deficits, including medullary and cerebellar infarctions, have also been described.

Case Summary: A 70-year-old patient presented an acute onset of vertigo and gait instability triggered by right head rotation.

Extracranial metastases in secondary glioblastoma multiforme: a case report.

Background: Glioblastoma (GBM) is known for its devastating intracranial infiltration and its unfavorable prognosis, while extracranial involvement is a very rare event, more commonly attributed to IDH wild-type (primary) GBM evolution.

Case Presentation: We present a case of a young woman with a World Health Organization (WHO) grade II Astrocytoma evolved to WHO grade IV IDH mutant glioblastoma, with subsequent development of lymphatic and bone metastases, despite the favorable biomolecular pattern and the stability of the primary brain lesion.

Conclusions: Our case highlights that grade II Astrocytoma may evolve to a GBM and rarely lead to a secondary metastatic diffusion, which can progress quite rapidly; any symptoms referable to a possible systemic involvement should be carefully investigated.

Frequency and outcome of olfactory impairment and sinonasal involvement in hospitalized patients with COVID-19.

Background: Olfactory dysfunction has shown to accompany COVID-19. There are varying data regarding the exact frequency in the various study population. The outcome of the olfactory impairment is also not clearly defined.
