A Retrospective correlative study of preoperative Radiological findings with intraoperative findings in post-covid-19 invasive rhino-orbital mucormycosis infection patients
Keywords:
post covid , mucormycosis , plain CT scan, contrast MRI scan.Abstract
Aim: To analyse combined computed tomography (CT) and magnetic resonance imaging (MRI) characteristics of invasive rhino-orbital mucormycosis (IROM) in post-COVID-19 infection patients and their correlation with intraoperative findings for accurate diagnosis and delineation of the extent of involvement of the disease.Material and method: In this study, we have selected 50 patients diagnosed to have post covid 19 invasive rhino-orbital mucormycosis who underwent combined plain CT/MRI with contrast preoperatively and endoscopic debridement of mucormycosis. A correlation of intraoperative findings with preoperative radiological findings of the extent of invasion was studied in a retrospective manner.Results: A good correlation was found between preoperative radiological findings in plain CT Paranasal sinuses, contrast MRI fat suppressed T2 images and intraop findings of endoscopic debridement of fungal sinusitis except for a few cases of frontal sinus pathology and pterygopalatine fossa involvement.Conclusion: Conjunctive use of plain CT, which depicts bone destruction and other reactive bony changes along with contrast MRI, which reveals characteristic findings of soft-tissue thickening of the involved sinuses with extension of disease to the orbits, cavernous sinus and intracranial structures are useful for accurate diagnosis and early recognition of the disease and its extension. Preoperative plain CT and MRI with contrast helps to initiate appropriate and timely treatment, which is vital to prevent a fatal outcome.
