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. Case N1: A prominent unibrow (synophrys) and elongated eyelashes were noted at 24 weeks of gestation with no other abnormal features. Case N 2: A prenatal ultrasound scan was performed at 24 weeks and revealed: horseshoe kidney and localized hypertrichosis on the lower back. Case N 3: Ultrasound exam at 24 weeks of gestation demonstrated localized hypertrichosis on the chin. Conclusion: Transient localized hypertrichosis with no other major findings has a favorable prenatal outcome.
