摘要

臺灣地處於肺吸蟲症流行病區，和食用未經熟煮的淡水蝦蟹有關。人類是肺吸蟲的宿主之一，食入的幼蟲會穿過腸道，腹膜，橫隔膜，和肋膜而進入肺臟。因此肺臟和肋膜腔內的變化是肺吸蟲最常見的臨床表現。過去的研究報告顯示，肺吸蟲在肺臟和肋膜腔的表現可以和肺結核與惡性腫瘤相似，而診斷的確立須要經由蟲卵的發現。然而就我們所知，以鈣化的肋膜腔內腫瘤來表現的肺吸蟲症並未被報導過。本個案指出，肺吸蟲症有可以靠近橫隔膜的鈣化腫瘤來表現，且合併長期的右上腹痛。

Calcified pleural tumor is a rare presentation in paragonimiasis, a parasitic disease that is endemic in Taiwan. The lung and pleura are the most common destinations for the parasite. Pleuropulmonary manifestations have been widely reported, and may mimic several lung diseases, such as lung cancer and pulmonary tuberculosis. The diagnostic requirement is a search for ova in the pleural effusion or pleural tissue. We report a 62-year-old woman who had suffered from intermittent right upper quadrant pain for 7 years. Computed tomography of the chest showed an 8-cm centrally calcified mass lesion in the right costophrenic angle. Biopsy of the mass revealed Paragonimus westermani ova surrounded by dense hyalinized fibrotic tissue. This case demonstrates that paragonimiasis may present as a calcified pleural tumor.
