MRI as a road‐map for surgical intervention of acute invasive fungal sinusitis

xlomafota13 shared this article with you from Inoreader MRI as a road‐map for surgical intervention of acute invasive fungal sinusitis in Covid‐19 era Via Clinical Otolaryngology Abstract Objectives Acute invasive fungal sinusitis AIFS has high mortality rate, and its incidence has increased without explanation in Covid-19 era. Proper diagnosis and effective surgical debridement have a crucial role in decreasing this high mortality rate. MRI could detect early ischemic changes with localization of extrasinus devitalized fungal inflamed tissue to guide surgical intervention. Study design Prospective study Setting ORL-HNS department -Zagazig University. Methods T1 with gadolinium and T2 fat suppression sequences were investigated and correlated with surgical findings in cases recently recovered from Covid-19 "seroconversion". Loss of contrast enhancement LOCE/black sign in T1+G was hypothesized to reflect necrotic areas while hyperintense signal/white sign in T2 fat suppression was hypothesized to correlate with severely inflamed devitalized tissue in periantral region These radiological findings were correlated with intraoperative findings to identify positive predictive finding. Results 40 patients were included in this study, of which 38 had LOCE/ black sign in T1+G 95%. True ischemic turbinate was detected only in 35 cases (positive predictable value PPV= 92.1%). Hyperintense signal/ white sign in T2 fat suppression was detected in orbit, pterygopalatine-infratemporal fossa, sphenoid process, zygoma, external skin, and these findings were correlated with intraoperative findings (PPV ranging from 72.7% to 100%). Conclusion MRI has a crucial role in localization of devitalized tissue, and subsequently guides surgical intervention. View on the web Inoreader. Take back control of your news feed.
