Preoperative diagnosis of Gallbladder squamous cell carcinoma (GBSCC) is difficult, and the contrast-enhanced ultrasound (CEUS) pattern has never been reported before. We present a case of GBSCC where CEUS revealed special findings that facilitated early diagnosis. CEUS demonstrated irregular peripheral ring-like enhancement during the arterial phase, with hypoenhancement in the late phases, and an irregular non-enhancing area persistently present in the center of the lesion.
Keywords: case report; contrast-enhanced ultrasound; gallbladder; squamous cell carcinoma; time-intensity curve.
