Although imaging provides important diagnostic information, histopathological examination is required for confirmation.

Serum biochemistry demonstrated a cholestatic pattern with increased alkaline phosphatase and gamma\u2010glutamyl transferase activities. Abdominal radiographs revealed a cranial abdominal mass, and ultrasonography identified a multiloculated cyst with thin septa and no mural nodules. Contrast\u2010enhanced computed tomography confirmed a 163\u00a0\u00d7\u00a0148\u00a0\u00d7\u00a0136\u00a0mm cystic hepatic mass with homogeneous fluid attenuation, non\u2010enhancing septa and no solid components. Exploratory laparotomy enabled complete excision with preservation of hepatic tissue. Partial resection of the common bile duct followed by end\u2010to\u2010end anastomosis was performed to restore bile flow. Histopathological examination confirmed hepatobiliary cystadenoma. Recovery was uncomplicated, and at the 3\u2010month follow\u2010up the cat was clinically normal, with no ultrasonographic evidence of recurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Large multiloculated hepatic cystic lesions with homogeneous fluid contents and no enhancing mural nodules should prompt consideration of hepatobiliary cystadenoma in cats.
