Abstract:
PURPOSE: The purpose of this study is to describe the ultrasonographic findings of ovary-containing hernias of the canal of Nuck. METHODS: This was a retrospective analysis of 22 hernia cases of the canal of Nuck. The following gray scale and color Doppler ultrasonographic features were analyzed: the site and the size of the hernia, the texture of the hernia contents, and the presence or absence of blood flow in the hernia contents. RESULTS: All of the patients had swelling of the right inguinal region (n=10), left inguinal region (n=8), or both (n=2). On ultrasonography, the hernias appeared as either solid masses (n=17) or solid masses containing cysts (n=5). The mean anteroposterior diameter of the hernia sac of the canal of Nuck was 9.1 mm (range, 5 to 18 mm). The mean anteroposterior diameters of the hernia sac were 11.6 mm (range, 7.6 to 18 mm) for hernias containing an ovary, and 8.3 mm (range, 5 to 13 mm) for hernias containing omental fat. During surgery, among the 17 cases with solid-appearing hernia contents on ultrasonography, omental fat was identified in the hernia sac in four cases, but no structure was identified in 13 cases. All five cases that appeared as solid masses containing cysts on ultrasonography contained ovary tissue in the hernia sac. Among the four cases of ovary-containing hernias, color Doppler ultrasonography identified blood flow within the ovary in three cases, but no flow signal was seen in one case of incarcerated hernia. CONCLUSION: Ultrasonography may be helpful for the diagnosis of ovary-containing hernias of the canal of Nuck by detecting solid masses containing small cysts.
