摘要
目的总结颅内脂肪瘤的磁敏感成像信号改变特点。方法搜集我院自2015至2017年经影像学检查确诊颅内脂肪瘤7例,所有病人均进行了常规MRI和磁敏感成像,回顾和归纳其信号改变特点。结果全部7例颅内脂肪瘤常规MRI均表现脂肪的信号特征,与皮下脂肪信号相似;但是SWI序列均表现为低信号,与皮下脂肪信号不同。结论颅内脂肪瘤SWI呈低信号,局部存在明显磁场变化,提示颅内脂肪瘤并不是简单的脂肪堆积,可能存在更复杂的病理学改变。
Objective To summarize to susceptibility weighted imaging appearance characteristics of intracranial lipoma. Methods 7 cases who admitted to our hospital from2015 to 2017 were found with intracranial lipoma occasionally during the imaging scans.All of the patients had the routine MRI and SWI examinations, the MRI signal changes characteristics were retrospective reviewed. Results All of the 7 intracranial lipomas showed fat characteristics on the routine MRI sequences, same as the subcutaneous fat;but showed obviously low signals on the SWI sequence, which was different with the subcutaneous fat. Conclusion Intracranial lipomas would show a low signal on SWI imaging and with obviously local magnetic field changes. This imply the intracranial lipomas are not a local accumulation of fat tissue, but have more detail pathologic changes.
