A 43-year-old woman had diabetes insipidus and amenorrhea. There was panhypopituitarism on endocrine testing and visual field examination showed inexorably progressive loss to bitemporal hemianopsia. All radiographic findings were normal, but craniotomy disclosed the cause of this chiasmal syndrome to be an intrasellar abscess which, on culture, grew a Gram-positive anaerobe, Peptococcus. Intrasellar or pituitary abscess is rare, but it must always be considered in the differential diagnosis of the chiasmal syndrome, since loss of pituitary and visual function may occur much more rapidly than with the tumors most often responsible for this syndrome and since surgical cure is possible.
一名43岁女性患有尿崩症和闭经。内分泌检查显示全垂体功能减退，视野检查显示双颞侧偏盲呈不可阻挡的进行性丧失。所有影像学检查结果均正常，但开颅手术发现导致这种视交叉综合征的原因是鞍内脓肿，培养结果显示为革兰氏阳性厌氧菌消化球菌。鞍内或垂体脓肿很罕见，但在视交叉综合征的鉴别诊断中必须始终予以考虑，因为垂体和视功能丧失的发生可能比最常导致该综合征的肿瘤要快得多，而且手术治愈是有可能的。
