The  cyst of the canal of nuck as a differential diagnosis of femoral or inguinal incarcerated hernia

Quiste de nuck como diagnóstico diferencial de hernia femoral o inguinal incarcerada

Introduction: the cyst of the canal of Nuck is an unusual entity of low and unknown incidence. Itis origin is a persistent vaginalis process in females thus it is considered a congenital anomaly. It consists of parietal peritoneum accompanying the round ligament within the inguinal canal. Its equivalent in males is a communicating hydrocele. Objective: to present this rare condition in adult women and highlight its importance as a differential diagnosis with an incarcerated inguinal or femoral hernia.  Case: a female patient with a suspected cyst of the canal of Nuck by clinical and ultrasound findings, who underwent surgery, confirming the cyst by pathology examination. Follow-up at the outpatient clinic evidenced adequate progression. Discussion: it is a rare condition and being aware of its existence can facilitate perioperative management of these cases preventing confusion with an incarcerated inguinal hernia. Conclusion: while it is true that some cases can be associated with femoral or inguinal hernias, it usually presents as a standalone condition.
