Eight patients with neurocysticercosis were studied with CT and magnetic resonance (MR) imaging. Two cysts were shown better with MR than with CT. A conspicuous, high-intensity mural nodule containing the scolex allowed specific identification of intraventricular and parenchymal cysticerci. CT evidence of calcification and metrizamide enhancement in the nodule was also noted in one case. Racemose cysts were seen in the cerebellopontine angle and under the anterior septum pellucidum. Fluid in apparently live cysticerci and in racemose cysts had MR signal properties closely paralleling CSF. A thin subependymal or subpial rim of high signal intensity around the intraventricular and one of the racemose cysts was consistent with tissue reaction and aided diagnosis. While MR showed only one of numerous calcifications, it may be more sensitive than CT in the recognition of perifocal edema and of parenchymal and subarachnoid cysts, may replace invasive ventriculography in the diagnosis of intraventricular cysts, and may be useful in determining the viability of cysts and their response to therapy.
对8例神经囊尾蚴病患者进行了CT和磁共振（MR）成像研究。有2个囊肿在MR上显示得比CT更好。一个含有头节的明显的高强度壁结节有助于明确诊断脑室内和脑实质内的囊尾蚴。在1例中还注意到结节内钙化和甲泛葡胺强化的CT表现。在桥小脑角和透明隔前下方可见葡萄状囊肿。活囊尾蚴和葡萄状囊肿内的液体具有与脑脊液非常相似的MR信号特征。脑室内和其中一个葡萄状囊肿周围有一层薄的室管膜下或软膜下高信号边缘，这与组织反应相符，有助于诊断。虽然MR仅显示了众多钙化中的一个，但在识别灶周水肿、脑实质和蛛网膜下囊肿方面可能比CT更敏感，在诊断脑室内囊肿时可替代有创性脑室造影，并且在确定囊肿的存活情况及其对治疗的反应方面可能有用。
