Neonatal Gallstones

Abstract

A term male infant was born by spontaneous vaginal delivery to a 23 year old gravida 2 para 2 mother. His weight, length, and head circumference were 2720g (8%), 47cm (6%) and 31.5cm (1%) respectively; the remainder of his physical examination was unremarkable. The pregnancy was complicated by intra-uterine growth retardation, gestational diabetes controlled with glyburide, and gestational thrombocytopenia. The mother had a past medical history of obesity, BMI of 32 (>95%), HPV infection, and atypical squamous cells of the cervix. A fetal ultrasound at 38 weeks gestational age showed echogenic foci consistent with cholelithiasis (Figure 1); a previous US at 37 weeks gestational age was normal. On routine laboratory testing the mother’s blood type was O positive and the infant’s was A+ (positive). His transcutaneous bilirubin was 4.3 mg/dL at 36 hours of life. Both mother and son were discharged after two days without problem.
