A rare case of @entity4236 presenting symptoms as a brain @entity3 is reported. A 47-year-old- @entity1 was admitted to Yamagata City Hospital complaining of @entity135 and @entity10 attack. Neurologically, bilateral slight choked disc and right anosmia were found. The otolaryngologist in this hospital pointed out a reddish-purple polypoid @entity5 in the right nasal cavity. But there were no episodes of @entity1415 or obstruction before admission. CT scan on admission showed the @entity5 density in the right upper nasal cavity and ethmoid sinus, which partially infiltrated into the orbital cavity, and enhanced heterogenous high density mass in the inner basal portion of the right frontal lobe. Carotid angiogram revealed a small @entity5 blush in the ethmoid region and avascular @entity66 in the right frontal region. On the 11th hospital day, surgical @entity5 was performed by the otolaryngologist and the evident @entity5 cells in the fibrous tissue were observed. So the endonasal removal of the @entity5 and the total removal of the @entity5 were achieved. On operation, the continuity of @entity5 was not observed. The histological pictures of both @entity5 were similar and the diagnosis was @entity4236 . From histological and operative findings, we concluded the @entity5 was metastatic lesion from nasal origin. CT scan taken after the operation showed the @entity5 rested only in the right ethmoid sinus.(ABSTRACT TRUNCATED AT 250 WORDS)
