A preterm female neonate was born via caesarean section to a healthy 31-year-old woman at an estimated gestational age of 34 weeks. Preeclampsia was diagnosed at 31st weeks of gestation and a complete antenatal corticosteroid therapy cycle was administered.
No evidence was found of congenital malformations on prenatal ultrasounds. At delivery, birth weight was 1780 grams (appropriate for gestational age). Resuscitation with positive pressure ventilation was required, with an Apgar Score of 5 and 10 at 1 and 5
minutes, respectively. The baby was admitted to the neonatal intensive care unit and was managed conservatively. Her urine output was normal in the first 24 hours. At 36 hours of life she developed oligoanuria. Clinical examination revealed a 15 x 0.5 mm spherical
swelling protruding in the vulvar introitus with well-defined limits, elastic consistency, yellowish and with superficial vascularization, more lateralized to the right, probably blocking the distal meatus of the urethra (Figure 1). No vaginal bleeding or
breast enlargement was observed and she remained stable, except for voiding difficulty. The swelling spontaneously drained after 12 hours with discharge of mucous material without any characteristic smell, leaving visible the glandular orifice (Figure 2).
Renovesical ultrasound was normal.
