Ultrasonography and contrast-enhanced ultrasound (CEUS) imaging of large cell neuroendocrine carcinoma (LCNEC) in the urinary bladder. a Sonography showed a hypoechoic mass with hyperechoic margins in the anterior wall of the urinary bladder. b Superb microvascular imaging (SMI) showed strong blood flow signals in the mass. c CEUS imaging showed that the lesion achieved hyper-enhancement in the early phase in comparison to the bladder wall. d The lesion showed hypo-enhancement compared to the bladder wall. e Time-intensity curves (TICs) was created by analysing the ROI (green) positioned in the tumor and the reference ROI (yellow) in the bladder wall. TICs showed the lesion was initially enhanced at 9 s, the time to peak was 13 s and wash-out occurred at 40s
