Cysts of the canal of Nuck: ultrasound and magnetic resonance imaging findings

Abstract

Cyst of the canal of Nuck is a rare cause of inguinal swelling in woman. We report a case of a cyst of the canal of Nuck in which sonography showed a tubular cystic structure with internal septae localized within the inguinal canal. Magnetic resonance examination demonstrated that the mass was hypointense on T1-weighted and hyperintense on T2-weighted series and that there were fine hypointense septae inside the mass on the T2-weighted sequence. Diagnosis of cyst of the canal of Nuck was confirmed by surgery and subsequent histopathologic evaluation.Sommario La cisti del canale di Nuck è una rara causa di tumefazione inguinale nelle donne. Riportiamo un caso di cisti del canale di Nuck in cui l'ecografia aveva evidenziato una struttura tubulare cistica caratterizzata da setti interni, localizzata nel contesto del canale inguinale. L'esame di RM aveva confermato la natura cistica della lesione, che appariva pertanto ipointensa in T1 e iperintensa con fini sepimentazioni ipointense nelle sequenze T2 pesate. La diagnosi di cisti del canale di Nuck è stata successivamente confermata all'intervento chirurgico e dall'esame isto-patologico. ª

Cyst of the canal of nuck in pediatric patients

“…This disease called hydrocele of the canal of Nuck, cyst of the canal of Nuck and female hydrocele, is accepted equivalent of the spermatic cord cyst (encysted hydrocele) occurring in boys. [12345]…”

Laparoscopic Intracorporeal Hydrocelectomy and Posterior Wall Suture Repair of the Hydrocele for the Canal of Nuck

“…In the case of encysted-type HCN, the bulging status persists without spontaneous reduction, similar to that in the case of an incarcerated inguinal hernia. Sonography is a useful diagnostic technique because HCN typically appears as a well-defined hypoechoic lesion [10]. The encysted hydroceles in this study were serous, hemorrhagic, and inflammatory types.…”

Fetal vulvar cysts with spontaneous resolution

“…Cevik et al 7 report a case of urinary retention with hydronephrosis in a neonate with a Bartholin’s duct cyst compressing the urethra but diagnosed in the second day of life. Similarly, cyst of the canal of Nuck is a rare pathology,8 9 not reported in most textbooks of gynaecology or surgery,5 6 10 11 occurring in the paediatric population4 8 9 12 13 and in adult women 6 10–12 14. In the prenatal period, hydrocele is well documented only in male patients 15…”
