title: The sphenoid sinus--a site for metastasis.
abstract: While metastatic tumors to the nose and the paranasal sinuses overall are unusual, metastasis to the sphenoid sinus is exceedingly rare. Presented are 26 cases of metastasis to the sphenoid sinus. Seven were treated at UCLA between 1955 and 1988, and 19 additional cases were discovered from a search of the medical literature. The patients ranged from 14 months to 79 years of age. The most common tumor sites from which sphenoid metastases arose were the prostate and the lung. In 11 of the 26 cases, the sphenoid sinus metastasis was the first presentation of malignancy. Patients manifested signs and symptoms that were indistinguishable from those from primary tumors of the sinus. They included headache, facial pain, visual changes, and single or multiple cranial neuropathies. While cure of patients with sphenoid metastasis has not been reported, significant palliation with resolution of morbidity is possible in many patients with radiation therapy. Although metastasis to the sphenoid sinus is an uncommon entity, when present, signs and symptoms relating to this metastasis are frequently the first presentation of disease. As such, patients with sphenoid sinus symptoms suggestive of sphenoid sinus malignancy should be vigorously evaluated for the possibility of primary as well as metastatic tumor of the sinus.
