Actinomycosis is rarely accompanied by fungus balls. It is difficult to distinguish between actinomycosis and a fungus ball due to their similar clinical and computed tomography scan results. Thus, a meticulous histopathological examination is required for definite diagnosis. We report a case of actinomycosis accompanied by a fungus ball, found incidentally in a patient without rhinologic symptoms. The patient was successfully treated with endoscopic sinus surgery, followed by short-term antibiotic therapy. We suggest that shortterm antibiotic therapy may be more appropriate than long-term antibiotic therapy based on our case study as well as several other studies. [ABSTRACT FROM AUTHOR]

Intraosseous hemangiomas account for 1% of all bone tumors and primarily originate from the vertebral column and skull bones. However, intraosseous hemangiomas of the nasal cavity are extremely rare. Here, we report a case of intraosseous hemangioma with a cavernous pattern arising from the middle turbinate that was preoperatively misdiagnosed as chronic rhinosinusitis with polyps. Except for nasal obstruction, there were no specific rhinologic symptoms. The tumor was excised en bloc by the endoscopic endonasal approach without preoperative embolization. [ABSTRACT FROM AUTHOR]
