    Abstract:
    Isolated aspergillosis of the sphenoid sinus is a difficult diagnosis because the often misleading clinical manifestations of this rare disease develop late. We report a case of invasive aspergillosis uniquely involving the sphenoid sinus revealed by clinical features suggesting pseudotumor of the pituitary in an immunocompetent man. A 71-year-old man presented sudden onset palsy of the abductor nerve of the left eye. Neuroimaging suggested a pseudotumor of the pituitary. Sphenoid sinusitis was discovered at surgery. The diagnosis of aspergillosis was provided by the histology examination of the sphenoid mucosa. Despite medical treatment with itraconazol alone then in combination with amphotericine B, the infectious process progressed to the pituitary, the cavernous sinus, the upper orbital fissue and the optic canal. Cure was finally achieved after a second surgical procedure to drain and aerate the sphenoid sinus. Aspergillosis of the sphenoid sinus is usually discovered due to neurological signs such as a cavernous sinus syndrome, pseudotumor of the pituitary or the orbit. Diagnosis is often made intraoperatively or at histology examination. Invasive forms almost always are seen in immunosuppressed subjects. In our case, the patient was immunocompetent and had no past history of sinusitis. The invasive sphenoid aspergillosis invaded bone tissue, the cavernous sinus and the meninges.
