Toxoplasmosis is the most common cerebral mass lesion encountered in HIV-positive patients. Previously uncommon, this disease has increased markedly since the AIDS epidemic. There are occasionally unusual appearances of central nervous system toxoplasmosis that make diagnosis by standard imaging techniques difficult or impossible. More recently, MR spectroscopy has increased the ability to differentiate between various central nervous system lesions.
弓形虫病是HIV阳性患者中最常见的脑实质病变。这种疾病以前并不常见，但自艾滋病流行以来显著增加。中枢神经系统弓形虫病偶尔会有不寻常的表现，使得通过标准成像技术进行诊断变得困难甚至不可能。最近，磁共振波谱分析提高了鉴别各种中枢神经系统病变的能力。
