Mesenchymal neoplasms of the urinary bladder are exceedingly rare and display remarkable diversity. These tumors demonstrate distinct pathological features as well as variable biological behavior and cross-sectional imaging findings. The rarity of tumors, nonspecific symptoms and seemingly normal cystoscopic findings (particularly with small and exophytic tumors) frequently lead to misdiagnosis or missed diagnosis. While some tumors display characteristic cross-sectional imaging findings that may suggest a diagnosis, imaging findings are mostly nonspecific. Histopathological examination is required for accurate diagnosis, management and prognostication. The purpose of this article is to review the cross-sectional imaging findings of a diverse spectrum of mesenchymal tumors of the urinary bladder.
膀胱间叶性肿瘤极为罕见，表现出显著的多样性。这些肿瘤具有明显的病理学特征，以及不同的生物学行为和影像学表现。肿瘤的罕见性、非特异性症状和看似正常的膀胱镜检查结果（尤其是对于小的、外生性肿瘤）常常导致误诊或漏诊。虽然一些肿瘤具有特征性的影像学表现，可能提示诊断，但影像学表现大多是非特异性的。准确的诊断、治疗和预后需要进行组织病理学检查。本文旨在回顾膀胱间叶性肿瘤的各种不同类型的影像学表现。
