血管脂肪瘤最早于1960年被Howard和Helwig[1]报道,是一种少见的良性肿瘤,是脂肪瘤的一种变异体,占脂肪瘤的5%~17%[2-3]。血管脂肪瘤主要由成熟的脂肪组织和毛细血管组成,常发生于四肢和躯干的皮下组织,主要表现为多发的疼痛皮下结节,直径常小于2 cm[4]。发生在纵膈的血管脂肪瘤非常少见,临床症状不明确,术前影像学检查显示病灶内含脂肪组织是最主要的特征,但病理组织学是确诊纵隔血管脂肪瘤主要手段。目前国内外文献大多数报道CT、MRI的影像学特征,但99Tcm-MIBI SPECT/CT亲肿瘤显像尚未见报道,我们现对1例纵隔血管脂肪瘤99Tcm-MIBI SPECT/CT亲肿瘤阳性显像进行报道。
纵隔血管脂肪瘤99Tcm-MIBI SPECT/CT显像一例

摘要: 笔者报道了一例纵隔血管脂肪瘤患者的99Tcm-MIBI SPECT/CT显像情况,分别从临床症状、CT及99Tcm-MIBI SPECT/CT亲肿瘤阳性显像、病理诊断等方面介绍该病的特点,并通过文献复习加深了对纵隔血管脂肪瘤的认识。研究结果显示,纵隔血管脂肪瘤99Tcm-MIBI SPECT/CT亲肿瘤阳性显像未见明显摄取,提示术前多种影像学检查有利于观察纵隔血管脂肪瘤的生长方式、内部成份等,有助于临床诊断与鉴别诊断。Abstract: The author reported one case of mediastinal angiolipoma of 99Tcm-MIBI SPECT/CT imaging, The characteristics of the disease were introduced according to clinical symptoms, CT, 99Tcm-MIBI SPECT/CT tumor positive imaging and pathological diagnosis, meanwhile, the understanding of mediastinal angiolipoma was deepened by reviewing the literature. The result of imaging findings of 99Tcm-MIBI SPECT/CT showed no significant ingestion. Conclusion suggests that preoperative multiple imaging examinations are helpful to observe the growth pattern and internal components of mediastinal angiolipoma and is helpful for diagnosis and differential diagnosis.
