Intracranial aspergillosis in immunocompetent adult patients without risk factors: a systematic review

Neurosurg Rev. 2022 Mar 12. doi: 10.1007/s10143-022-01738-y. Online ahead of print.


The clinical features and prognostic factors of intracranial aspergillosis in immunocompetent patients without risk factors are not well known. PubMed, Scopus, Google Scholar, and Web of Science were searched for all relevant case reports/series on adult patient (≥ 18 years) with aspergillosis published from 1976 to 2018. One hundred eighty-two patients (median age, 40 years; range, 18-83 years; male:female, 115:67) were identified. Types of intracranial aspergillosis included intracranial mass from the skull base (54.9%), pure intraparenchymal disease (23.6%), meningoencephalitis (13.2%), and dural-based mass (8.2%). Vascular complications occurred in 44 patients (26.3%). Eighty-one patients (44.5%) had favourable final clinical outcomes without any deficits, whereas 58 (31.9%) died. Disease-related mortality improved significantly over time (43.1% [28/65] before 2000, 25.9% [30/116] after 2001; p = 0.021). Patients with meningoencephalitis demonstrated the highest mortality rate (79.2%, 19/24). Medical non-responders (patients whose disease course worsened after receiving the initial medication regimen) and vascular complications (the presentation of subarachnoid haemorrhage, intracerebral haemorrhage, or infarction related to the rupture or occlusion of intracranial vessels) were significantly associated with mortality (p < 0.001). Findings from the current review may help predict patient prognosis at the initial assessment and determine potential prognostic factors.
