Hepatic mucinous cystadenoma of the left liver in a pacient with right hepatectomy for hepatic hydatid cyst

Cystadenoma of the liver is a rare benign neoplasm with a intrahepatic ingrowth, with a representation of only5 % of the hepatic cystic lesions The literature describes the malignant degeneration in average of 10 % ofcases. Material and met|hod: We present the case of a 48 year old patient with personal surgical history ofright hepatectomy for hepatic hidatic cyst, with a tumoral mass in the epigastric region accompanied by painthat appears spontaneous and by palpation . The abdominal-pelvic computer tomography performed carriedout raised the suspicion of hepatic hidatid cyst. During surgery we identified the presence of a seroushepaticcyst inthe segment IV of the liver. The result of the anatomical pathological examinationhas reviled acystic mucinous neoplasm with low-grade dysplasia (cystadenoma of the liver). Discussion The biochemicaltests are in most cases normal, the alkaline phosphatase and Bilirubin can be modified in the case in whichthe mass creates compression on the biliary ducts. As regards the tumor markers CA 19-9, they can have thevalue slightly raised; The surgical intervention is the treatment proposed in the majority of cases, within theoncological limits of resection. In this case, the patient’s surgical antecedents (right hepatectomy) have madethe resection in oncological limits impossible, the only option being the oncological dispensarisation andperiodic biochemical and imaging monitoring . Results The clinical presentations of the hidatid hepatic cystand hepatic cystadenoma may be similar as well as the imaging scans, such as ultrasonography, computertomography, magnetic resonance, imaging may not establish a diagnosis of certainty.
