Aspergillus clival abscess, especially without a sphenoid sinus lesion, is a very rare infection of central nervous system. In this report, we describe the successful treatment of a patient with aspergillus clival abscess. A 63-year-old man was referred to our hospital with the diagnosis of sphenoid mass lesion in magnetic resonance image accompanied by headache and diplopia. The computed tomography scan revealed a clival cystic lesion without connection with the sphenoid sinus. The patient underwent the endoscopic endonasal clival approach and histopathological examination revealed aspergillosis. Postoperatively, the patient was given IV amphotericin-B for 2 weeks and oral voriconazole for 3 months. After surgery, patient's headache and diplopia disappeared. Aspergillus abscess originating from the skull base is rare but has a high mortality rate. Histopathological confirmation via endonasal approach and intensive antifungal therapy should be started for a successful treatment.
