卡氏肺孢子虫是免疫受抑制患者肺炎较为常见的原因。如不治疗其死亡率为90～100%,而合适的治疗则治愈率为79～90%。在成人,较易感染此肺炎的疾病有何杰氏病、肾移植后免疫抑制、自血病特别是急性淋巴细胞性白血病,以及获得性免疫缺陷综合征(AIDS)。作者总结5例临床资料,就~(67)镓肺扫描对此类肺炎的诊断价值提出讨论。方法与结果本组5例,2例系已接受肾移植者,3例为淋巴瘤患者。5例均表现为发热、呼吸困难、低氧血症,而肺部物理检查和X线检查无特殊发现。给予~(67)镓柠檬酸盐3mci(大约40μci/kg体重)后24小时进行镓扫描。其结果一例见右肺尖部~(67)镓吸收增加,一例在扫描时所能见到的两肺区内~(67)镓吸收呈弥散性增加;3例~(67)镓明显地局限在胸腔内,呈弥散
Pneumocystis carinii is a common cause of pneumonia in immunocompromised patients. If not treated, the mortality rate is 90 ~ 100%, while the appropriate treatment, the cure rate was 79 ~ 90%. In adults, the disease that is more susceptible to this pneumonia is Jerseys disease, immunosuppression after renal transplantation, autoimmune diseases, especially acute lymphoblastic leukemia, and Acquired Immune Deficiency Syndrome (AIDS). The authors summarize 5 cases of clinical data on ~ (67) gallium lung scans on the diagnosis of such pneumonia are discussed. Methods and Results The group of 5 patients, 2 patients had received kidney transplant, 3 patients with lymphoma. Five cases showed fever, dyspnea, hypoxemia, and physical examination of the lungs and X-ray examination without special findings. Gallium scans were performed 24 hours after administration of ~ (67) gallium citrate 3 mci (approximately 40 μci / kg body weight). One example of this result is the increase of ~ (67) gallium absorption in the right apex, a diffuse increase of ~ (67) gallium absorption in both lung regions seen in one case, and the obvious limitation of 3 cases of ~ (67) gallium In the chest, was diffuse
