| Popis: | Objectives To review the literature regarding the use of intracranial imaging as a screening tool for idiopathic olfactory loss (IOL) and to review the incidence of identifying a sinonasal or intracranial neoplasm as a result of intracranial imaging. Methods A systematic review of published English-language literature was performed using PubMed, Ovid MEDLINE, Scopus, and Cochrane databases. Results Of the 694 available abstracts, 5 met inclusion criteria for this review. Out of 470 eligible patients, intracranial imaging identified tumors causing IOL in 8 patients (1.7%). Tumor detection rates ranged from 0% to 4.9%. Of the 470 eligible patients, intracranial imaging detected intracranial or sinonasal pathology, excluding tumors, causing IOL in 53 patients (11%). The findings ranged from 0.77% to 23%. Of the 604 eligible IOL patients, 470 (81%) underwent intracranial imaging, ranging from 53% to 100%. Conclusions In most cases, diagnostic imaging in IOL patients is frequently ordered. This study finds computed tomography or magnetic resonance imaging to be an important recommendation given to all patients with IOL. Although the overall rate of detecting tumor from diagnostic imaging is low, it is important to offer diagnostic imaging to this subset of patients to avoid missing tumors at an early stage. |
