Abstract:
In this article, the authors discuss imaging features of common and less-common epithelial and nonepithelial bladder neoplasms. Epithelial tumors include entities, such as urothelial cell carcinoma, squamous cell carcinoma, and adenocarcinoma, along with less-common entities, such as small cell and carcinoid tumors. Nonepithelial or mesenchymal tumors are also less commonly encountered and include benign entities, such as leiomyoma and neurofibroma, and malignant entities, including leiomyosarcoma and lymphoma. Their imaging features with an emphasis on computed tomography and magnetic resonance imaging are described.
