蝶形骨洞ムコツェーレの2症例

SPHENOID MUCOCELE: A REPORT OF TWO CASES

　I．はじめに

　蝶形骨洞のムコツェーレあるいはピオツェーレは，副鼻腔ムコツェーレ（ピオツェーレ）のなかでもきわめてまれであるとされており，事実，従来の報告例も少ない。蝶形骨洞ムコツェーレ（ピオツェーレ）はその伸展とともに，蝶形骨洞の解剖学的位置に関連して，種々の脳神経症状，なかんづく著明な眼症状をきたし，またこれに反して鼻症状が軽微であるため，しばしば脳下垂体腫瘍をはじめとする種々の頭蓋内疾患と誤られやすい疾患でもある。われわれは最近，2例の蝶形骨洞ムコツェーレを経験し，若干の知見を得ることができたので，それらの2例について報告し，ご批判をあおぎたい。

　Two cases of sphenoidal mucocele are reported.

　The first case: A woman, aged 50, complained of loss of sight in the right eye, impaired vision of the left eye and headache. A pituitary tumor was suspected and operated with positive finding of the tumor. One year later the patient was operated for sphenoidal mucocele. The patient was completely relieved of her former symptoms.

　The second case: A man, aged 30, complained of repeated impairment of vision. Examination revealed a mucocele in the region of the posterior end of the middle turbinate. It was removed. Six months later the sphenoidal sinus required an opening for presence of a mucocele. The patient was completely cured. Inspite of,the fact that, severe optical symptoms may be manifested with sphenoidal sinus mucocele, very little symptom may be shown in the nasal cavity. For this reason the affection may be easily misregarded to be that of pituitary involvement; careful examinations are required in the diagnosis of these cases.
