Adenocarcinoma of the ethmoid sinus

Abstract

Adenocarcinoma occurring in the paranasal sinus is relatively rare. The case of a 53-year-old male adenocarcinoma in the ethmoid sinus is reported. The patient presented complaining of headache, nausea and a disturbance of consciousness. The initial diagnosis was a brain tumor. The brain tumor was extirpated by a neurosurgeon. The final pathological daignosis was adenocarcinoma. The patient was thereafter introduced to our department for an investigation of the primary lesion. MRI and CT examinations demonstrated the primary lesion to be in the ethmoid sinus. Up to now, only 14 cases of adenocarcinoma of the ethmoid sinus have been reported in Japan.
