Abstract:
Hepatobiliary cystadenomas are rare, truly benign cystic epithelial tumors with the potential to become cystadenocarcinoma. The initial symptom is vague, nonspecific abdominal pain, frequently in middle-aged women, but patients may be asymptomatic. Abdominal ultrasonography may be diagnostic. Intracystic fluid, obtained by sonographically guided fine-needle aspiration, may contain elevated levels of carcinoembryonic antigen. Complete resection or enucleation is the treatment of choice. We present the cases of two patients with hepatobiliary cystadenoma.
