Sfenoid sinüs mantar topu veya miçetoma, çok nadir görülen ve görme kaybı, başağrısı ve kraniel sinir felçleri gibi nonspesifik semptomlara neden olan bir hastalıktır. Tanı genelde nonspesifik semptomlar için yapılan görüntüleme sonrası konur. Bu çalışmada, görme kaybı ve şiddetli başağrısı olan hastada izole sfenoid mantar topu vakasını tartıştık. Hastanın semptomları sfenoidotomi sonrası tamamen düzeldi. Abstract RADIOLOGICAL AND CLINICAL CHARACTERISTICS OF SPHENOID FUNGUS BALL PRESENTING WITH VISION LOSS AND HEADACHE We report a rare case of isolated sphenoid ‘fungus ball’ presenting as vision loss and headache. Sphenoid fungus ball also called as mycetoma is a rare disease and it causes nonspecific symptoms such as headache, visual disturbance and cranial nerve palsies. Diagnosis usually made after imaging studies for non-specific symptoms. In this report, we present a case of isolated sphenoid fungus ball with the symptoms of vision loss and severe headache. Symptoms subsided after sphenoidotomy and clearance of fungus ball.

Symptoms and treatment strategies are the same as isolated bacterial infection of sphenoid sinus which is also a rare disease. The most commonly encountered isolated sphenoid sinus lesions (ISSD) are sinusitis, fungal infection, mucoceles, or tumors and fungal infections are the third most common cause of ISSD lesions (14.5%) [1]. Patients usually have asymptomatic during the early stages of the disease, symptoms appear when inflammation becomes more serious. Isolated sphenoid sinusitis caused by fungus is much rarer, and is more difficult to detect due to the nonspecific symptoms and absence of any characteristic signs during endoscopic examination [2-8]. Recently, the detection rate of ISSD has increased because of the development of imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI). Aspergillus fumigatus is the most common causative fungus isolated from sphenoid sinus, as well as from the paranasal sinuses. Important structures such as cranial nerves, carotid artery and cavernous sinus are related closely to sphenoid sinus. We report a case of isolated sphenoid fungus ball presenting with severe headache and vision loss.
