目的：子宫肌瘤红色变性（出血性梗死）可引起急性腹痛。本研究进行了识别有用的MR特征在诊断这种罕见的并发症子宫平滑肌瘤.材料和方法：磁共振成像从5例患者症状为7至20天的病理证实的红色变性进行了回顾性评价，并与组织病理学发现。T1加权像（WI）呈高信号环，T2加权像呈低信号环。这些发现与病变周围大量充满红细胞的扩张血管相对应。边缘的信号特征最好的解释为丰富的细胞内高铁血红蛋白在这些vessel.Conclusion的效果：识别这些特征可能有助于放射科医生区分症状性红变性从其他临床条件，需要手术干预。
Objective: Red degeneration (hemorrhagic infarction) of uterine leiomyoma can cause acute abdominal pain. This study was undertaken to identify MR features useful in diagnosing this rare complication of uterine leiomyoma.Materials and Methods: Magnetic resonance imaging from five patients symptomatic for 7 to 20 days with pathologic confirmation of red degeneration was retrospectively evaluated and correlated with histopathologic findings.Results: The lesions had a common MRI appearance: hyperintense rim on T1-weighted imaging (WI) and hypointense rim on T2-WI. These findings corresponded with numerous dilated vessels filled with red blood cells at the periphery of the lesion. The signal characteristics of the rim are best explained as an effect of abundant intracellular methemoglobin in these vessels.Conclusion: Recognition of these characteristics may help radiologists differentiate symptomatic red degeneration from other clinical conditions that need surgical interventions.
