Fetal premature excess vertebral linear calcification: a case series.

During embryogenesis, the vertebrae begin development during the 6th week of gestation via two lateral chondrification centers per segment. It was assumed that when disruptions occur in the process of somitogenesis during membranous vertebral body formation, chondrification and ossification will follow the anomalous membranous vertebral body scaffolding, resulting in an anomalous vertebral formation, such as a hemivertebra. Another hypothesis is that hemivertebra may result from anomalous distribution of intersegmental arteries of the vertebral column.

Fetal Renal Duplicated Collecting System at 14-16 Weeks of Gestation.

(1) Background: To examine the incidence of the prenatal diagnosis of the renal double-collecting system (rDCS) and describe its clinical outcome and associated genetic abnormalities. (2) Methods: This retrospective study included women who attended the obstetric clinic for early fetal anatomic sonography with findings of a renal DCS. Diagnosis was conducted by an expert sonographer using defined criteria.

Prenatal detection of gastrointestinal bubbles since early pregnancy: Clues to correct diagnosis.

Objective: To characterize gastrointestinal bubbles detected since early pregnancy and to describe corresponding diagnoses.

Method: A retrospective cohort review of all cases in which gastrointestinal bubbles were detected starting in early prenatal transvaginal scans at 14-17 weeks of gestation between the years 2007 and 2021. Sonographic features and data regarding associated anomalies, genetic abnormalities, and pregnancy outcome were evaluated.

Transient fetal hypertrichosis - Three cases.

We Summarize a three cases of transient fetal hypertrichosis in low risk preganant women. Hypertrichosis has been previously associated with over 140 different syndromes (OMIM); however this finding is rarely described in prenatal ultrasound. In this study we describe the finding of hypertrichosis which resolved later in gestation.
