Purpose

Evaluate the role of contrast-enhanced ultrasonography (CEUS) as a powerful tool and aid to better identify and define soft tissue tumours in abdominal cavity, otherwise not detactable by Duplex B- mode US, to allow their safer percutaneous biopsy

Methods and materials

12 patients (medium age 57 years-old,5 M 7 F) with radiological (TC/MRI) diagnosis of focal liver lesions (7), focal lesions of the cephalic portion of pancreas (3) and malignant recurrence after duodenum-pancreatectomy in pancreatic loggia (2), have been retrospectively considered between January 2018 and February 2019. In all cases the identification of the target lesion by Duplex B-mode US was not possible and CE-US (employing Sonovue, sulfur hexafluoride) was employed to better delineate them and finalize their percutaneous biopsy. We considered an arterial phase (20-25...

Results

Technical success was achieved in all (12) patients and in all cases the target lesion was identified with more accuracy and the percutaneous biopsy allowed with more precision and safety. In all patients 2 samples were taken and the confirmation of diagnostic biologic material came from the histologic corroboration. In none of the cases the samplig was not possible and in none of the cases major complicancies such as bleeding or haemorrhage due to injury to abdominal parenchymas or great vessels occurred

Conclusion

The elevated rate of techical success reported, the absence of major complicancies and the faster performance, confirm the added value of CE-US as an advantageous tool and aid to better identify and delineate abdominal soft tissue focal lesions not detactable by Duplex B-mode US to allow their safer and faster percutaneous biopsy
