Five AIDS patients with previously diagnosed and treated toxoplasmosis presented with hyperdense precontrast CT approximately 6 months after the CNS infection. An MR study was performed in all cases. The CT hyperdensities were characterized on MR by a high signal intensity on T1 images in four cases. In two of these, pathological correlation confirmed hemorrhage. In the fifth case, MR findings were consistent with calcification, which was verified by pathological examination.
五名先前已诊断并接受过弓形虫病治疗的艾滋病患者，在中枢神经系统感染后约6个月，CT平扫显示高密度影。所有病例均进行了磁共振成像（MR）检查。在MR图像上，四例患者的CT高密度影表现为T1加权像高信号。其中两例经病理证实为出血。第五例患者的MR表现符合钙化，病理检查予以证实。
