The hydrocele of the canal of Nuck is quite a rare condition and results from the failure of obliteration of the distal portion of evaginated parietal peritoneum within the inguinal canal which forms a sac containing fluid. It generally presents with painless inguinal swelling. Ultrasonography and MRI is plays an important role to differentiate from the other conditions presenting with inguinal swelling. We present the imaging findings of a case in 5-year-old girl.
