Abstract
The MR features of a giant cell tumor that predominantly involved the posterior elements of a thoracic vertebra are presented. This extradural neoplasm compressed and displaced the spinal cord. The tumor had low to intermediate signal on short-repetition-time images and predominantly high signal on long-repetition-time images. It showed mild heterogeneous enhancement with gadopentetate dimeglumine.
摘要
本文呈现了主要累及胸椎后部结构的骨巨细胞瘤的磁共振成像（MR）特征。这种硬膜外肿瘤压迫并推移了脊髓。该肿瘤在短重复时间图像上呈低至中等信号，在长重复时间图像上主要呈高信号。静脉注射钆喷酸葡胺后，肿瘤呈轻度不均匀强化。
