    Abstract:
    We treated three cases of inflammatory granulomas extending from the sphenoid sinus to the cavernous sinus. Case 1 was that of a 36-year-old male with diplopia and right ptosis. Case 2 was that of a 40-year-old male with frontal headache. Case 3 was that of a 70-year-old female with left impaired vision and frontal headache. In the first case, MRI demonstrated a mass lesion extending from the right half of the sphenoid sinus to the cavernous sinus and retropharyngeal space. In the second case the granuloma extended from the right cavernous sinus to the right retroorbital space. In the last case, MRI demonstrated diffuse Gd-DTPA enhancement of the left cavernous sinus and the left half of the sphenoid sinus. In all cases an operation was performed using the sublabial rhinoseptal approach, and the tumor in the sphenoid sinus was removed. Histological examination revealed an inflammatory granuloma in all 3 cases. In the first case the clinical symptoms improved following administration of glucocorticoids. In the second case the mass in the cavernous sinus decreased in size postoperatively. In the last case, the clinical symptoms gradually improved with administration of antibiotics after surgery. Granuloma of the cavernous sinus is difficult to diagnose, but when a similar pathological lesion coexists in the sphenoid sinus, a definitive diagnosis can be easily made via the sublabial rhinoseptal approach.
