Preliminary results suggest that CT is a useful imaging tool in patients with laparoscopic repair of incisional vetral hernia. It showed the correct site of the mesh, subclinical fluid collections in the abdominal wall, and recurrent hernia.

Introduction and importance Intraductal papillary neoplasm of the bile duct (IPNB) is a tumour with a very low incidence in the Western world, characterised by a high risk of malignant transformation and unknown prognosis. It is a new entity which was adopted by the WHO in 2010 as a precursor lesion of cholangiocarcinoma. Intrahepatic bile duct is the most common site of origin for IPNB. Case presentation Hereby, we present a case of an asymptomatic 63- year-old man, referred to our department after routine ultrasonography showing a multifocal cystic lesion on the left hepatic lobe. Further screening modalities (CT, MRI abdo) confirmed a complex cystic liver lesion with atypical features. The patient underwent left hepatectomy. Histopathology showed a cystic type intrahepatic IPNB, which was completely resected (R0). The follow up in 2 yrs post-operation showed no signs of recurrence. Clinical discussion The diagnosis and management of IPNB remain challenging. A multimodality imaging approach is essential in order to diagnose IPNB, assess tumour location and extent and plan the optimal treatment strategy. Conclusion Complete surgical resection (R0) with close postoperative follow-up offers long-term survival.
