Role of Perineal Ultrasound in Differentiating Paraurethral Cysts in Newborns

Background: Paraurethral cyst or Skene’s gland cyst is a rare congenital abnormality and a rare cause of paraurethral cysts resulting from Skene’s gland, which has been reported in few studies so far. The Skene’s duct cyst can cause urinary retention or anuria; moreover, it can appear as an inter-labial mass in neonates. Case report: Our patient was a one-day-old female neonate presented with anuria and an inter-labial mass found in physical examination. The patient was referred by a pediatric surgeon to our department for sonographic evaluation. We did an ultrasound examination and made a tentative diagnosis of paraurethral cyst based on grayscale appearance and ultrasonographic criteria of the cystic lesion. The patient underwent surgery, a biopsy was obtained, and the specimen was sent for pathologic evaluation to a pediatric pathologist. The result confirmed our diagnosis as a Skene’s duct cyst. Conclusion: In this study, it was found that paraurethral cysts in newborns can be investigated using perineal ultrasound, which can eliminate the need for invasive surgeries.
