A case of cerebral metastases is presented in which the initial brain scan did not demonstrate the lesion because steroid medication had been started 18 hr earlier. The lesion was seen after the patient had been off medication for several days. Therefore, brain scans should be performed prior to starting or following the removal of steroid medication for several days in order to avoid false-negative results secondary to steroid effects.
本文报告一例脑转移瘤病例，该病例最初的脑部扫描未显示病变，因为在扫描前18小时已开始使用类固醇药物。在患者停药数天后，病变显现出来。因此，为避免类固醇效应导致的假阴性结果，脑部扫描应在开始使用类固醇药物之前或停药数天后进行。
