巨细胞瘤被认为是一种局部侵袭性良性肿瘤，远处转移的倾向较低。它们主要存在于长骨中，在头骨中很少见。破骨细胞样巨细胞不表现出有丝分裂活性并含有大量细胞核。在此，我们描述了颞叶巨细胞瘤的一例。 CT 成像显示肿瘤实性区域存在不均匀强化。 T1 加权 MR 成像上出现中等到高信号强度和 T2 加权 MR 成像上非常低的信号强度是由于先前出血中存在含铁血黄素。 (C) 2002 Elsevier Science Inc. 保留所有权利。
The giant cell tumor is considered to be a locally aggressive benign tumor and has a low tendency toward distant metastasis. They are primarily present in the long bone and are rare in the skull. The osteoclast-like giant cells do not demonstrate mitotic activity and contain large numbers of nuclei. Herein, we described a case of giant cell tumor in the temporal lobe. Heterogenous enhancement is shown on CT imaging in solid areas of tumor. The appearance intermediate to high signal intensity on T1-weighted and very low signal intensity on T2-weighted MR imaging were due to the presence of hemosiderin from prior hemorrhage.
