We report a case of chronic expanding hematoma in the adrenal gland. Mixed signal intensity in a mosaic pattern was seen on T2-weighted images. A focal area suggesting a subacute hematoma was also noted. The dynamic CT scan showed heterogeneous contrast enhancement in the arterial phase and heterogeneous spread of the enhanced area within the tumor. Awareness of this finding may prevent the misdiagnosis of a tumor as a neoplastic intratumoral hemorrhage.
我们报告一例肾上腺慢性扩展性血肿。在T2加权图像上可见呈镶嵌样的混合信号强度。还发现一个提示亚急性血肿的局灶性区域。动态CT扫描显示动脉期不均匀强化，强化区域在肿瘤内呈不均匀扩散。认识到这一发现可防止将肿瘤误诊为肿瘤内肿瘤性出血。
