Isolated aspergillosis of the sphenoid sinus is a difficult diagnosis
because the often misleading clinical manifestations of this rare dise
ase 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 sinu
sitis was discovered at surgery, The diagnosis of aspergillosis was pr
ovided by the histology examination of the sphenoid mucosa, Despite me
dical treatment with itraconazol alone then in combination with amphot
ericine B, the infectious process progressed to the pituitary, the cav
ernous sinus, the upper orbital fissue and the optic canal, Cure was f
inally achieved after a second surgical procedure to drain and aerate
the sphenoid sinus, Aspergillosis of the sphenoid sinus is usually dis
covered due to neurological signs such as a cavernous sinus syndrome,
pseudotumor of the pituitary or the orbit, Diagnosis is often made int
raoperatively or at histology examination. Invasive forms almost alway
s are seen in immunosuppressed subjects, In our case, the patient was
immunocompetent and had no past history of sinusitis, The invasive sph
enoid aspergillosis invaded bone tissue, the cavernous sinus and the m
eninges.
