When a cytomegalovirus infection occurs within the first 16 weeks of pregnancy, leading to intrauterine transmission, it has severe implications for the fetus. The risk of a transplacental infection in the first trimester is 40 %, and 10–15 % of these infected children show symptoms after birth. 80 % of infected children suffer from severe impairment. We present a rare case of the infection of one fetus in a diamniotic-dichorionic twin pregnancy.

Purpose Papillary thyroid carcinoma with desmoid-type fibromatosis (PTC-DTF) is extremely rare. So far, only 4 cases describing the ultrasound findings of this variant have been reported. Here, we describe the ultrasound findings of 13 cases of PTC-DTF, focusing especially on the DTF area.

Influencing Factors of 2 D Shear Wave Elastography of the Muscle – An Ex Vivo Animal Study

One of the challenges of muscle ultrasound is anisotropy, where the ultrasound beam may be reflected in a different direction than the excited ultrasound beam. The aim of the ex vivo study was to assess possible measurement confounders, e. g. linear versus convex probe, probe pressure and ROI placement and size, on 2D-SWE of porcine muscle.

Fig. 3 2 D SWE of porcine muscle: a B-mode image with 1 cm × 1 cm B-mode ROI and SWV overlapped, b circular ROI placement, c 1 cm width and 2 cm depth B-mode ROI shows decreasing SWV measurements and values with increasing depth and d 2 cm width and 1 cm depth B-mode ROI at the same placement depth showing markedly increased SWV values with increasing ROI width.
