Purpose Rhinonasal mucormycosis is an aggressive fungal infection that primarily affects immunocompromised patients, particularly those with uncontrolled diabetes or post-COVID-19 complications. The infection begins in the nasal cavity and paranasal sinuses but may extend into the orbit and intracranial structures, resulting in severe complications such as blindness, stroke, and death.Ultimate learning objective is: Recognizing the characteristic imaging features of rhino-nasal mucormycosis across various stages of disease progression. Identifying critical MRI findings indicative of orbital and intracranial extension, including early signs of vascular involvement,...
Read more Methods and materials This is a retrospective observational study conducted on 10 patients diagnosed with rhinonasal mucormycosis, confirmed by histopathology or microbiological culture, who underwent MRI imaging as part of their diagnostic evaluation.Study Setting and Timeframe: The study was conducted in a tertiary care hospital. Patient data was collected over a period of January 2020 to December 2023.Data Collection: Patient demographics, comorbidities (e.g., diabetes mellitus, post-COVID-19 status, Hansen disease, HIV). Imaging data were retrospectively reviewed and analyzed by two radiologists with experience in...
Read more Results Orbital involvement (fig 5, 6, 7, 11, 14, 15, 16, 18 and 21) was noted in 60% of cases, presenting as proptosis, optic nerve, and extraocular muscle involvement in the form of heterogeneous enhancing soft tissue in the intra as well as extraconal compartment of orbit  appearing hypointense on T1, hyperintense on T2/FLAIR showing few foci of diffusion restriction on DWI with corresponding low ADC values and few foci of blooming on SWI with corresponding hyperintensity on phase sequence. There...
Read more Conclusion MRI emerges as a beacon in the labyrinth of rhinonasal mucormycosis, illuminating the hidden corridors of disease progression with unparalleled precision. Beyond its diagnostic prowess, MRI acts as a guide for clinicians, unraveling the intricate patterns of intra-orbital, vascular, and intracranial involvement. Its ability to visualize the silent threats lurking within soft tissues and critical structures transforms clinical decision-making, empowering timely and targeted interventions.By bridging the gap between early diagnosis and lifesaving treatment, MRI not only maps the battlefront but...
