Unlike epithelial tumors, connective tissue tumors are uncommon, representing only 3% of all bladder tumors. Leiomyoma of the bladder is the most frequent non-epithelial benign tumor of the bladder. Magnetic resonance imaging (MRI) is highly useful for diagnostic purposes and to determine the degree of extension. Only few reports of sonographic findings have been reported for leiomyoma of the bladder. The tumor usually develops within the bladder. Extravesicular formations have also been reported as well as a few intramural localizations. The characteristic feature is the absence of mucosal involvement. We analyzed the MRI findings in a case of leiomyoma of the bladder with intra and extravesicular development, inflammatory reaction of the bladder wall and uterine adherences in a woman with a past history of chronic cystitis. The role of diagnostic MRI is discussed.
与上皮性肿瘤不同，结缔组织肿瘤并不常见，仅占所有膀胱肿瘤的3%。膀胱平滑肌瘤是膀胱最常见的非上皮性良性肿瘤。磁共振成像（MRI）对诊断及确定肿瘤的浸润程度非常有用。关于膀胱平滑肌瘤的超声检查结果报告较少。肿瘤通常在膀胱内生长。也有关于膀胱外形成以及少数壁内定位的报道。其特征是不累及黏膜。我们分析了一例膀胱平滑肌瘤患者的MRI表现，该肿瘤有膀胱内及膀胱外生长、膀胱壁炎症反应以及子宫粘连，患者有慢性膀胱炎病史。本文还讨论了诊断性MRI的作用。
