Contrast-enhanced ultrasound (CEUS): one step forward in the identification of "high risk" solitary fibrotic tumors of the liver.

BACKGROUND: Solitary fibrous tumors of the liver (SFTL) are rare neoplasms, whose identification and definition of malignant potential are challenging. CASE PRESENTATION: A 62-year-old patient underwent conventional imaging and CEUS to characterize an indeterminate liver lesion after other imaging techniques were inconclusive. In fact, all diagnostic techniques concluded that it was a partially fibrotic lesion, while CEUS determined its extra-hepatocellular origin and malignant potential, initially hypothesized to be a cholangiocarcinoma. Due to the possible risk of seeding following a biopsy procedure, the patient was a candidate for surgery. Subsequently, histopathological examination revealed SFTL. CONCLUSION: CEUS confidently characterized the malignancy and hypothesized the origin of the liver lesion, thus aiding in treatment planning.

Go-BACK catheter for treatment of iliac artery chronic total occlusion: A case report.

The Go-BACK catheter is a novel device designed to be used for both intraluminal crossing or re-entry, into a vessel lumen from the subintimal space during subintimal angioplasty. It is reserved for cases where reentry has not been possible using conventional wire and catheter techniques. We report our experience in recanalization of the chronic total occlusions of the common iliac artery (CIA) using the Go-BACK catheter, in cases where other techniques were unsuccessful.
