What is it about?
Ultrasound diagnosis of invasion depth of the gallbladder carcinoma is shown. We report a case of polyploid gallbladder carcinoma invading the shallow subserosa with a conically thickened outermost hyperechoic layer but a hypoechoic area in the deeper part of the tumor.

Why is it important?
Ultrasound and pathological correlation demonstrated that the hypoechoic area represented an adenocarcinoma invading the shallow subserosa accompanied by abundant fibrosis. The prognosis of the case is good and the patient survived more than 19 years after the radical operation.
Perspectives
Polyploid gallbladder tumors with a deep hypoechoic area and a conically thickened outermost hyperechoic layer suggest shallow T2 gallbladder carcinoma and may provide good postoperative prognosis.
