| 目的 探讨肺癌脑转移瘤瘤内出血的影像特点。方法 26例肺癌脑转移瘤瘤内出血患者，接受CT 和MRI检查。结果 共发现脑内转移瘤43个，其中出血性转移瘤38个，占转移瘤总数的88.4%，表现为CT和MRI上一致性高密度或高信号病灶，或瘤体内部分高密度或高信号出血，隔期复查显示出血有吸收但肿瘤占位征象较前明显；增强扫描显示肿瘤有结节状或环行强化。结论 发现脑内不典型部位出血病灶时，应注意有转移瘤瘤内出血的可能，隔期复查血肿吸收但占位征象更明显、以及增强扫描肿瘤强化等有助于转移瘤的诊断。 |

| Objective To evaluate the imaging features of intracranial hemorrhagic metastatic tumors from lung cancer. MethodsIn twenty six cases of intracranial hemorrhagic metastatic tumors, 14 were examined by CT, 7 by MRI, and 5 by both CT and MRI. ResultsAll 43 intracranial metastatic tumors were found, and 38 (88.4%) of them showed hemorrhage within tumors. Some of the tumors presented as homogeneous high density lesions on CT, or high signal intensity on MRI T1WI and T2WI, some also presented as partial hemorrhage within tumors, and had ring or nodular enhancement after intravenous Gd DTPA enhancement. Conclusion Some intracranial hemorrhagic metastatic tumors from primary lung cancer present as intracranial hematoma. Some special features on images such as atypical lesions location, irregular shape, inhomogeneous density or signal and ring or nodular enhancement are helpful in diagnosing of hemorrhagic metastatic tumors. |
