A 28-year-old man had a 1-year history of hemoptysis. Consequently, he underwent a medical examination. A right pleural effusion, left hydropneumothorax, and multiple pulmonary nodular shadows were found on chest radiography. During a detailed interview, he reported that the hemoptysis began after eating "kejang" (a raw crab preparation) with a friend a year previously. His peripheral blood eosinophil count and serum IgE level were elevated. In addition, ova were detected in the sputum and bilateral pleural effusion. Morphological examination of the ova and immunoserological examination led to the diagnosis of Paragonimus westermani infection. The pleural effusion could be partially drained, and his symptoms and radiographic results showed improvement after treatment with Praziquantel administered at a dose of 75 mg/(kg x day) for 3 days. After one month, he and his friend ate seasoned raw crabs, Paragonimus was diagnosed in his friend. This case suggests that on encountering a paragonimus infection, everyone who ate food prepared in the same kitchen should be contacted because of possible infection with paragonimus.
一名28岁男性有咯血病史1年。因此，他接受了医学检查。胸部X线检查发现右侧胸腔积液、左侧液气胸和多个肺结节阴影。在详细询问病史时，他报告说咯血始于1年前与一位朋友一起食用“kejang”（一种生蟹制品）之后。他的外周血嗜酸性粒细胞计数和血清IgE水平升高。此外，痰液和双侧胸腔积液中均检测到虫卵。虫卵的形态学检查和免疫血清学检查确诊为卫氏并殖吸虫感染。胸腔积液可部分引流，给予吡喹酮75mg/（kg·天）治疗3天后，他的症状和影像学结果有所改善。1个月后，他和他的朋友食用了调味生蟹，其朋友被诊断为并殖吸虫感染。该病例表明，遇到并殖吸虫感染时，由于同一厨房制作的食物可能导致并殖吸虫感染，应联系所有食用过这些食物的人。
