Abstract

Four patients with brain tumors were diagnosed with atypical teratoid/rhabdoid tumors and underwent CT and MR imaging. For all tumors, aggressive features were shown by imaging studies and included hydrocephalus, apparent invasion of the adjacent brain and dura, and marked mass effect. The striking heterogeneity of the atypical teratoid/rhabdoid tumor shown by imaging studies reflects the histopathologic complexity of these tumors, and awareness of atypical teratoid/rhabdoid tumor is important in making the correct diagnosis of this uncommon but probably underdiagnosed entity.

摘要

4例脑肿瘤患者被诊断为非典型畸胎样/横纹肌样肿瘤,并接受了CT和MR成像检查。对于所有肿瘤,影像学研究均显示出侵袭性特征,包括脑积水、明显侵犯相邻脑实质和硬脑膜以及显著的占位效应。影像学研究显示的非典型畸胎样/横纹肌样肿瘤显著的异质性反映了这些肿瘤的组织病理学复杂性,认识非典型畸胎样/横纹肌样肿瘤对于正确诊断这种不常见但可能诊断不足的实体很重要。
