Summary

Mucormycosis is a serious fungal infection caused by a group of molds called mucormycetes. It commonly affects people with weakened immune systems, such as those with diabetes mellitus or taking immunosuppressive drugs for a long time. Mucormycetes proliferate in blood vessel walls and penetrate the cribriform plate to enter the brain, causing cavernous sinus thrombosis, brain abscesses, and possible cranial nerve involvement. Affected people usually present with a black necrotic eschar is seen on the face. Mucormycosis is with surgical debridement and amphotericin B.
