Radiographic Manifestation of PCP in AIDS Patient

卡氏肺囊蟲肺炎是免疫不全的人最常見的伺機性感染，但在診斷上常有困難；因在疾病不同時期或感染時間的長短，其胸部放射學表現會有差異。雖然胸部放射學的表現不能作確定的診斷，但其仍是最具有參考價值的。一般常見的胸部放射學表現為兩側瀰漫性間質型浸潤，但在接受預防性Pentamidine使用的病人，其胸部放射學的表現會有變化，增加診斷上的難度。在此提出一個免疫不全病人卡氏肺囊蟲肺炎的病例，病患有多位性伴侶，且一位女友為後天免疫不全症候群患者。病患有慢性咳嗽、體重減輕、盜汗和急性發燒，胸部放射學上的表現為兩側瀰漫性間質型浸潤。在高度的警覺下，很快的診斷，並于治療。在此討論其胸部放射學上的表現，期能提高警覺，及早診斷，及早治療。

Pneumocystis carinii pneumonia (PCP) is the most common opportunistic infection in the immunocompromised host. However, early diagnosis is relatively difficult. The radiographic manifestations depend to a great extent, on the patient’s state of immunosurveillance, and the duration of infection. There is no pathognomonic radiographic pattern for pneumocystis carinii pneumonia, though radiographic examination is still a reliable and useful diagnostic tool. Pneumocystis carinii pneumonia is manifested by a diffuse perihilar interstitial infiltration; other variable patterns have been observed in patients under prophylatic pentamidine treatment. Herein, we present a case of PCP in an AIDS victim. He has had multiple sexual partners, and his girlfriend is also an AIDS patient. His major complaints included chronic cough, body weight loss, night sweating, and acute fever. Chest radiography showed a bilateral distribution of the diffuse interstitial infiltration. He was quickly diagnosed with a multiple infection, using a high index of suspicion, and received appropriate treatment.
