Contrast-Enhanced Ultrasound Characteristics of Bladder Leiomyoma: A Case Report

  Bladder leiomyoma is a rare benign neoplasm that may mimic a malignant lesion in medical images. We report a woman with bladder leiomyoma who was correctly diagnosed by contrast-enhanced ultrasound (CEUS). The patient was referred to our hospital after a bladder neoplasm was detected during a health checkup. CEUS showed fast wash-in and slow wash-out in the tumor, similar to a normal bladder wall. To conclude, bladder leiomyoma has its specific characteristics on CEUS, and this modality may be a good option for diagnosis of bladder leiomyoma.
