A 62-year-old male presented with a complaint of headaches and visual disturbances. A CT scan revealed inflammation of the left ethmoidal air cells and the sphenoidal sinus. An endonasal operation was performed, but it was not effective. The visual loss was progressive, although we attempted both antibiotic therapy and steroid therapy. Since the CT scan and the MRI suggested a rhinologic brain abscess and granulomatous tissues in the medial frontal base, they were subsequently removed by neurosurgeon. The symptoms improved temporally, but another brain abscess was found. Removal of the abscess was performed again, but the patient relapsed and finally died due to a subarachnoid hemorrhage. The histological diagnosis was of a fungal infection (candidiasis). The importance of early diagnosis, as well as local and host factors will be discussed in fungal infection.
