[Biliary cystadenocarcinoma: a case report disease]

Biliary cystadenocarcinoma is a rare tumour arising in a healthy liver. Prognosis is better than other malignant tumours of the liver. It frequently develops in a pre existing benign biliary cystadeonoma and usually occurs in middle-aged women. This tumour is difficult to diagnose because of the lack of specificity of clinical, biological and radiological features. We report the sonographic, computed tomographic and angiographic features of a case of biliary cystadenocarcinoma. A review of the literature is presented as well. The sonographic and CT findings suggestive of biliary cystadenocarcinoma are summarized. Treatment is surgical and diagnosis is confirmed at histopathology.
