Doctors suspected man had brain cancer. He actually had worms.
摘要
西班牙一名60岁男性因持续两周且不断加重的头痛及行为改变就医。神经系统检查显示其动作轻度迟缓，血液检查除IgE水平升高外基本正常。头部CT扫描发现大脑多处病变并伴有水肿。医生在《新兴传染病》病例报告中指出，该患者无免疫缺陷且无国际旅行史，最初高度怀疑为转移性癌症。
A 60-year-old man in Spain went to the doctor complaining of a headache that he couldn't shake. It had started two weeks prior and was only getting worse. He also said he had noticed subtle changes in his behavior.
In a neurological exam, doctors found he had a mild delay in his movements, but no other deficits. His blood work was generally normal except for elevated IgE, a signal of immune responses linked to allergies, autoimmune disease, and parasitic infections. The doctors did a computed tomography (CT) scan of his head and saw much more obvious evidence of a problem: There were multiple lesions distributed throughout his brain accompanied by swelling.
In a case report in Emerging Infectious Diseases, the doctors reported working through the possible conditions that could explain all the findings. They noted that the man was not immunocompromised and had never traveled internationally. Their top suspicion was metastatic cancer.
