[Invasive fungal brain abscess: a case report].

Mucormycsois, also known as zygomycosis, is an extremely serious acute invasive fungal infection（IFI）. The disease progresses rapidly and the mortality rate is high. Even if cured, it may leave behind serious sequelae. Immunocompromise is at high risk of mucormycosis. Rhino-orbital-cerebral mucormycosis（ROCM） is the most common type of mucormycosis. It can manifest as headache, nasal obstruction, exophthalmos, ophthalmoplegia and nerve palsy, loss of vision, arterial embolism, etc. A case of ROCM is reported in this paper. The etiology, course of development, clinical and imaging manifestations and treatment of ROCM are described in detail.
