[show abstract][hide abstract] ABSTRACT: Prenatal diagnosis of chromosomal disorders requires an invasive test in women regarded as being at high risk after screening. There is extensive evidence that effective screening for major chromosomal abnormalities can be provided in the first and second trimesters of pregnancy. With the association of some biochemical markers, it is possible to identify about 90% of chromosomal abnormalities. In this article, we aimed to review the important ultrasonographic markers of chromosomal abnormalities, including nuchal translucency, nasal bone, and nuchal skinfold thickness, based on the data available in the literature.
[show abstract][hide abstract] ABSTRACT: Actinomycosis is an uncommon chronic infection in which primary liver involvement accounts for 5% of all actinomycotic infections. Abdominal actinomycosis is a severe and progressive peritoneal infection due to an anaerobic gram-positive bacterium, Actinomyces israelii. The presence of a long-standing intrauterine device (IUD) is a well-known risk factor in young women. Although hepatic lesions are present in 15% of cases of abdominal actinomycotic infection, liver involvement in the majority of these cases is attributable to metastatic spread from other evident intraabdominal sites. Hepatic actinomycosis presents most commonly as a single abscess. However, hepatic actinomycosis can closely mimic a malignant tumor on clinical and radiological examination. Such lesions have been termed inflammatory pseudotumors. Tissue specimens for microscopic examination are necessary for diagnosis. We report a rare case of inflammatory pseudotumor of the liver caused by actinomycotic infection.

[show abstract][hide abstract] ABSTRACT: Mesenchymal hamartoma is a rare pediatric liver tumor. The tumor is mainly cystic but occasionally a solid component is seen. Therefore the tumor can be divided into two forms: (a) cystic predominant, and (b) stromal predominant. In this report, CT and MR features of stromal predominant type mesenchymal hamartoma are presented.
