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.

Calcifications in Thyroid Tumors on Ultrasonography: Calcification Types and Relationship with Histopathological Type 

Kaoru Kobayashi et al.

DOI: 10.1055/a-0591-6070

Ultrasound is a useful imaging modality for detecting and assessing thyroid nodules, and it is a key examination. The purpose of the study is to clarify the prevalence of calcifications within thyroid tumors on ultrasonography as well as the relationship between the calcification and histopathological types.

Can Ultrasound Alone Predict Papillary Thyroid Carcinoma with Desmoid-Type Fibromatosis? 

Kumiko Tajiri et al.

DOI: 10.1055/a-0591-6163

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. In a retrospective analysis of 13 cases the authors describe the ultrasound findings PTC-DTF, focusing especially on the DTF area.
