Ossified choroid plexus papillomaの1例

Ossified Choroid Plexus Papilloma: Case report

I．はじめに

　頭部単純撮影におけるchoroid plexus papillomaの石灰化像は文献的に4-25％の症例で認められるとされているが^{2,11,16,23）}，骨化が確認されたものは極めて少なく，これまで3例が報告されているにすぎない^7,15,18）．われわれは頭部単純撮影およびCT—上右側脳室下角に石灰化巣と思われる所見を認め，摘出標本の病理組織学的検索により骨組織の認められたchcoroid plexus papillo—maを経験したので若干の文献的考察を加え報告する．

While the calcification has been documented radiolo-gically in 4 - 25 percent of the cases with choroid plex-us papilloma, the ossification of choroid plexus papillo-ma has been reported only in 3 cases on literature. In this paper, we present a case of large ossified choroid plexus papilloma in the right lateral ventricle.

A 35-year-olcl man was admitted with left hemi-paresis and headache. Skull X-rays showed an abnor-mal calcified mass (25 mm × 23 mm × 14 mm) in the right temporal region.
