The authors report a case of epidermoid tumor attached to the dura of the frontal convexity and extending into the cerebral parenchyma, with unusual computed tomographic (CT) and magnetic resonance (MR) findings. The tumor appeared as a mixed density intracerebral mass containing dense calcifications on the precontrast CT scan, and the capsule was intensely enhanced on the postcontrast scan. It appeared as a mixed intensity lesion on both the T1- and T2-weighted MR images.
作者报告了一例表皮样肿瘤，该肿瘤附着于额叶凸面硬脑膜并延伸至脑实质，具有不寻常的计算机断层扫描（CT）和磁共振（MR）表现。在平扫CT扫描上，肿瘤表现为脑内混合密度肿块，含有致密钙化，增强扫描后包膜明显强化。在T1加权和T2加权MR图像上，它均表现为混合信号病变。
