PDFAbstract
Objective To summarize to susceptibility weighted imaging appearance characteristics of intracranial lipoma. Methods 7 cases who admitted to our hospital from 2015 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.
