誤診された前頭洞疾患の症例

　前頭洞局所症状を欠き長期間誤診され診断上意義ありと思われる前頭洞疾患の症例に遭遇したので報告する。

KATO and TAKITA report 2 cases in whom the diagnosis of pathological involve-mnet of the frontal sinus was arrived at only after a carefully drawn out studies have been made upon them and then, with a great difficulty. Because of this difficulty, it is sta-ted that the patients were committed to diag-nostic errors by Ophthalomologist, Internist and the Surgeon alike in succession.
