Hydrocele of the canal of Nuck (HCN) is a very rare cause of inguinal swelling in female infants and children. HNC is a rare developmental disorder. A 20 day-old female presented to a palpable mass in her both inguinal groin, which was first noticed first day of life. Ultrasonographic examination of both inguinal regions demonstrated fluid-filled cystic structures in the inguinal regions. This complex lesions diagnosed HCN and herniated ovaries. Ovarian vascularity were normal. A 13-year-old girl presented with swelling in the left inguinal region. The left inguinal bulge protruded when intraabdominal pressure increases. This painless bulge had persisted for 5 years. Sonographic imaging confirmed a thin-walled cyst, extending under left inguinal ligament an subtle comminication with the peritoneum. The MRI revealed an regular shaped, cystic mass lesion in the left inguinal region. There was not hernie. The lesion was consistent with HCN. This pathology is rare. The incidence of HCN is not known. Radiologists must be familiar with the abnormality for accurate diagnosis.The incarceration is an important risk. Differential diagnosis in female is wide. The final diagnosis results in surgery. These cases are presented in order to raise awareness of radiologists in inguinal mass examination in children.
