Abstract
- Biliary cystadenocarcinoma (BCAC) is an extremely rare intrahepatic cystic tumor. Patients usually present with nonspecific symptoms such as abdominal pain, abdominal distention, and abdominal mass. This tumor occurs most commonly in the left hemiliver and is thought to mainly develop from a benign biliary cystadenoma (BCA). At present, the disease is mainly diagnosed by ultrasound, CT, MR, and other imaging methods, and the main treatment is radical surgical resection. We reported a 75-year-old female with an unresectable huge BCAC (i.e., 161×145×122 mm in three orthogonal directions) and poor general condition (40 in Karnofsky Performance Status, KPS) who received sequential thermal ablation (i.e., cryoablation and microwave ablation) in combination with sclerotherapy using lauromacrogol. The diagnosis of intrahepatic BCAC was confirmed pathologically. Preablation grayscale US showed the BCAC with a clear boundary, regular shape, and cystic-solid mixed echogenicity, which appeared as a huge multilocular cystic lesions with thick internal sepatations. Preablation contrast-enhanced ultrasound (CEUS) showed honeycomb-like hyper-enhancement of the thick internal sepatations and cystic wall in the arterial and portal phase, and sustained enhancement of the thick internal sepatations and cystic wall in the late phase. 6-month postablation CEUS showed non-enhancement in most parts of the lesion in the arterial phase and 6-month postablation MRI showed the volume reduction ratio (VRR) was about 70%. The abdominal pain and abdominal distension were relieved remarkably, and her quality of life was greatly improved (70 in KPS). In conclusion, sequential thermal ablation in combination with sclerotherapy provides a successful translative therapy for this unresectable huge BCAC with a poor general condition, which makes subsequent curative surgery or ablation possible.
