We herein describe a case of an isolated multilocular hydatid cyst occurring in the basilar cisterns, with nondependent levels of different signal intensities shown on MR images. Three portions were visualized on T1-weighted images: the hyperintense inferior aspect, the isointense central part, and the superior aspect of lower signal intensity. The inferior portion was hypointense on T2-weighted images. This unusual appearance was caused by layering of hydatid sand and may represent a characteristic feature of hydatid disease.
我们在此描述一例发生于基底池的孤立性多房性包虫囊肿病例,磁共振成像(MR)显示其具有非依赖性不同信号强度水平。在T1加权图像上可见三个部分:高信号强度的下部、等信号强度的中央部分以及低信号强度的上部。下部在T2加权图像上呈低信号。这种不寻常的表现是由包虫砂分层所致,可能代表包虫病的一个特征性表现。
