A case of prenatal strangulated inguinal hernia

After a normal second trimester ultrasound during a scan performed at 29 weeks, a nonvascularized dilatation of 30 35 mm of the left scrotum was noted in the fetus (Figure 1, Supplemental Material, Video1). The penis and the contra- lateral testicle were normal in appearance. This was at rst hypothesized to represent a hydrocele, perhaps associated with testicular torsion or inguinal herniation. At the follow-ups performed at 31 and then at 34 weeks, the echogenic struc- ture became less homogeneous (Figure 2, Supplemental Ma- terial, Video2). The patient delivered spontaneously at 39 weeks. At postnatal ultrasound, both the testicles were nor- mally located, but a large left inguinal hernia was reported with meconium peritonitis and an entrapped intestinal loop causing the hydrocele.
