Objective: To characterize clinical and radiological features associated with biliary cystic tumors (BCTs) of the liver, and to define recurrence-free and overall survival. Background: Biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCAC) are rare tumors that arise in the liver. Methods: Between 1984 and 2013, 248 patients who underwent surgical resection of BCA or BCAC were identified. Clinical and outcome data were analyzed. Results: Median total bilirubin, CA19-9, and carcinoembryonic antigen (CEA) levels were 0.6 mg/dL, 15.0 U/mL, and 2.7 ng/mL, respectively. Preoperative imaging included computed tomography only (62.5%), magnetic resonance imaging only (6.9%), or CT + MRI (18.5%). Features on cross-sectional imaging included multiloculation (56.9%), mural nodularity (16.5%), and biliary ductal dilatation (17.7%). The presence of these factors did not reliably predict BCAC versus BCA (sensitivity, 81%; specificity, 21%). Median biliary cyst size was 10.0 cm(interquartile range, 7-13 cm). Operative interventions included unroofing/partial excision of the lesion (14.1%), less than hemihepatectomy (48.8%), or hemi-/extended hepatectomy (36.3%). On pathology most lesions were BCA (89.1%), whereas 27 (10.9%) were BCAC. At last follow-up, there were 46 (18.3%) recurrences; 2 patients who initially had BCA recurred with BCAC. Median overall survival was 18.1 years; 1-year, 3-year, and 5-year survival was 95.0%, 86.8%, and 84.2%, respectively. Long-term outcomes were associated with BCAC versus BCA, as well as the presence of spindle cell/ovarian stroma (both P
