A case report of congenital labial fusion

Results We describe a rare case of labial fusion diagnosed in 20th week of pregnancy. A 32 year-old healthy Gravida 2 was referred to our department for her routine 20-22nd week scan. The ultrasonographic examination showed single viable pregnancy with appropriate biometric assessment. Detailed anatomical scan revealed presence of thin-wall cystic anechogenic structure related to external genital with no other pathological findings. Amniocentesis confirmed normal female karyotype. We excluded infectious origin and congenital adrenal hyperplasia. There was no history of teratogens exposure. Later in 23rd week of pregnancy ascites was detected and the patient decided to terminate pregnancy. On autopsy, the fetus (440g/24cm) was diagnosed with ascites and severe deformation of vulva with elongated fused labia and dilated urethra. Internal genital structures were normal.
