MR Imaging Findings of Orbitofacial Infarction Secondary to Rhinoorbital Mucormycosis: A Case Report

Rhino-orbital mucormycosis is the most frequently fatal fungal infection commonly occurring in patients with poorly controlled diabetes mellitus and and those who are immunocompromised, and requires prompt treatment. We describe a case of rhino-or-bital mucormycosis with orbital cellulitis and paranasal sinusitis, as seen on initial MR images, which on follow-up images had evol ved to orbitofacial infarction. MR imaging was useful for the demonstration of orbitofacial infarction, seen as areas of lack of enhancement and thus suggesting vascular invo l vement by mucor hyphae.

The Findings of MRI and Transcranial Doppler Sonography in Three Cases of Moyamoya Disease

The confirmatory diagnosis of Moyamoya disease has been obtained by invasive angiographic examination. We report the results of MRI and transcranial doppler sonography of three cases ol Moyamoya disease, which ws disgnosed by clinical and angiography. We think that the diagnosis of Moyamoya disease can be made by noninvasive MRI and transcranial doppler sonography without conventional invasive angiography.
