“…Most patients with HCA are young, with minor symptoms on malignant progression; invasive procedures should preferably be avoided. While the risk of bleeding complications is very low when using an 18G core needle biopsy (0.6%) [ Haage et al 1999 ; Kadri Aribas et al 2010 ; Aribas et al , 2012 ], the risks are not negligible, and deaths due to bleeding complications have been reported [ Stattaus et al 2007 ]. In our practice a biopsy has not been performed to date, except where the diagnosis of a specific adenoma subtype was expected to alter clinical management.…”

Hepatocellular adenoma (HCA) is a rare, benign liver tumor. Discovery of this tumor is usually as an incidental finding, correlated with the use of oral contraceptives, or pregnancy. Treatment options have focused on conservative management for the straightforward, smaller lesions (<5 cm), with resection preferred for larger lesions (>5 cm) that pose a greater risk of hemorrhage or malignant progression. In recent years, a new molecular subclassification of HCA has been proposed, associated with characteristic morphological features and loss or increased expression of immunohistochemical markers. This subclassification could possibly provide considerable benefits in terms of patient stratification, and the selection of treatment options. In this review we discuss the decision-making processes and associated risk analyses that should be made based on lesion size, and subtype. The usefulness of this subclassification system in terms of the procedures instigated as part of the diagnostic work-up of a suspected HCA will be outlined, and suitable treatment schemes proposed.

“…On careful review of the literature, however, we noted that there is no universal agreement whether different needle sizes do affect diagnostic yield or not. For example, in biopsies of focal hepatic lesions, one study compared the results of biopsy in 268 patients and reported similar results for 18-and 14-gauge needles [12]. On the other hand, another study on 163 patients reported a significantly higher diagnostic yield for 16-gauge compared to 18-gauge needles [13].…”

Objective: To evaluate the efficacy, feasibility and safety of contrast-enhanced CT-guided core biopsy of retroperitoneal masses. Materials and Methods: Contrast-enhanced CT-guided biopsy of retroperitoneal masses was performed in 26 patients. Histopathological diagnosis was obtained and accuracy was calculated. Two blinded radiologists determined feasibility of biopsy procedures on routine CT-guidance, and compared accessibility of target lesions using contrast-enhanced and non-contrast-enhanced CT. Results: Satisfactory samples were obtained in all 26 patients and pathological diagnosis was made in 24. Accuracy was 95.5%. Routine CT-guided biopsy punctures were not satisfying in 4/26 patients, and contrast-enhanced CT scans rendered the target lesions more accessible in 16 patients. Conclusion: Contrast-enhanced CT-guided biopsy increases the feasibility of biopsy of retroperitoneal masses.

“…Seither konnte sich das Verfahren als komplikationsarme und genaue Methode zur Gewebeentnahme neben der Sonographie in der klinischen Routine durchsetzen und bietet den Vorteil der überlagerungsfreien, artefaktarmen und reproduzierbaren Darstellung der Läsion und benachbarter eventuell vulnerabler Strukturen [2,3]. In der Planungsschicht ist die exakte Bestimmung des Punktionsortes, des Einstichwinkels und der Einstichtiefe möglich.…”

CT-gesteuerte perkutane Biopsien zur Klassifizierung von fokalen Leberläsionen: Vergleich zwischen 14 G- und 18 G-Stanzbiopsienadeln

Abstract: CT-guided biopsy of hepatic lesions with the 18-g biopsy needle is of equivalent diagnostic accuracy when compared with the 14-g needle.
