Spontaneous Rhinorrhea Induced by Metastatic Carcinoma of the Sphenoid Bone

ABSTRACT

We have presented a case of spontaneous rhinorrhea which showed recurrence of supparative meningitis and destruction of the sella turhica and sphenoid sinus on the plain skull roentgenograms. By transantral and transnasal route, the portion of sphenoid sinus could easily be approached and exposed. Surgery with microscope easily permitted an identification of the point of cerebrospinal fluid fistula and the repair of it with graft and packing of temporal muscle fascia and pieces of gelfoam. The histopathology of sphenoid bone biopsied was an infiltrating carcinoma.
