副鼻腔炎による急性眼窩蜂窩織炎と誤つた眼瞼粉瘤腫化膿症の1例

　緒言

　副鼻腔と眼窩とは解剖学的に隣接しておるため，両者の療患が類似の症状を呈したり合併する事があり，その原因がどちらにあるか決定することが困難な場合が屡々ある。眼瞼の高度の腫脹・発赤並びに眼球突出，結膜浮腫が存在し，眼科で恐らく副算腔に原因するものであろうと言われた患者が経過観察後副鼻腔根治手術及びキリアン氏前頭洞手術を行い，始めてその眼症状は眼窩に及ぶアテロームの化膿によるものである事が判明した例を報告する。

Ida reports a case of infected tarsal cyst that presented a diagnostic difficulty because of concommittant involvement of sinusitis in the maxillary, ethmoids and left frontal sinus. The patient, affected with a fistula of the left upper eyelid evidently the result of for-mer surgical intervention, showed a marked congested swelling of the left upper eyelid with high fever and some exophthalmos. In this condition the patient arrived in the ENT Department from that of the Eye for further investigation of the sinuses as causative fact-ors of the ocular conditions. X-ray examinat ions confirmed the diagnosis of sinusitis. Con-sequently the maxillary sinus, the ethmoids and left frontal sinuses were treated by opera-tive procedures. It was only after these procedures had been undertaken that it was found that the ocular symptoms were unrelat-ed to involvements of sinusitis but, in reality due to infected unhealed tarsal cyst.
