Cronobacter sakazakii (C. sakazakii) is a bacterium known to cause severe neonatal infections in premature infants with the consumption of contaminated powdered milk formula. Adult infections are rare, and there have been no reports of pyosalpinx due to C. sakazakii to date.
We report a case of left pyosalpinx due to C. sakazakii in a sexually inactive postmenopausal woman. A 70-year-old woman presented to our hospital with left lower abdominal pain and fever. Abdominal computed tomography disclosed a cystic mass continuous with the left edge of the uterus. Urgent laparotomy revealed a ruptured left pyosalpinx with pus-like content. Left salpingo-oophorectomy, resection of the right tube, and washing of the abdominal cavity with saline were performed. Pathological examination of the left adnexa showed tubal tissue with acute inflammation and inflammatory exudate, which were compatible with pyosalpinx, and pus culture yielded C. sakazakii.
This is the first case report of pyosalpinx due to C. sakazakii. Cronobacter sakazakii infections in adult women might occur in the elderly, whose immunity has weakened. Further accumulation of cases of C. sakazakii infection is needed to clarify the etiology and behavior of C. sakazakii in adults.
阪崎克罗诺杆菌是一种已知会在食用受污染的婴儿配方奶粉的早产儿中引起严重新生儿感染的细菌。成人感染罕见，迄今为止尚无阪崎克罗诺杆菌导致输卵管积脓的报道。
我们报告一例绝经后无性生活的女性因阪崎克罗诺杆菌导致左侧输卵管积脓的病例。一名70岁女性因左下腹痛和发热就诊于我院。腹部计算机断层扫描显示一个与子宫左缘相连的囊性肿块。急诊剖腹探查发现左侧输卵管积脓破裂，内容物呈脓性。行左侧输卵管卵巢切除术、右侧输卵管切除术及腹腔生理盐水冲洗。左侧附件的病理检查显示输卵管组织有急性炎症和炎性渗出物，符合输卵管积脓，脓液培养检出阪崎克罗诺杆菌。
这是首例阪崎克罗诺杆菌导致输卵管积脓的病例报告。成年女性阪崎克罗诺杆菌感染可能发生在免疫力减弱的老年人中。需要进一步积累阪崎克罗诺杆菌感染病例以阐明其在成人中的病因及行为。
