作者复习了1961年以来发现的临床-病理学特征与Hassard等描述的内淋巴囊肿瘤(ELST)相似的病例的临床、手术记录和光镜、电镜发现。最近的4例作了颞骨的CT,其中后两例作了MRI研究。CT扫描层厚1.5mm,行横断和改良的冠状层面成象。MRI采用头线圈横断与冠状层面成象。层厚3～5mm,间距0～1mm,TR400～2000ms/TE12～70ms。病人临床症状为耳聋(4例)、平衡不稳(2例)、耳鸣(1例)、面肌颤搐(1例)、面肌无力(1例)。肿瘤形
The author reviewed clinical, surgical records, and light and electron microscopy findings of clinical-pathological features found since 1961 that were similar to those described by Hassard et al. for endolymphatic sac tumors (ELST). In the most recent 4 cases, humeral CT was performed, and the latter two cases were studied by MRI. The CT scan was 1.5 mm thick and it was transected and improved with coronal imaging. MRI uses a cranial coil transverse and coronal plane imaging. Layer thickness 3 ~ 5mm, pitch 0 ~ 1mm, TR400 ~ 2000ms/TE12 ~ 70ms. The patient’s clinical symptoms were deafness (4 cases), equilibrium instability (2 cases), tinnitus (1 case), facial muscle twitch (1 case), facial muscle weakness (1 case). Tumor shape
