Two adult cases of canal of Nuck cyst: diagnosis and treatment

Abnormalities of the canal of Nuck are rare congenital defects in females, typically repaired in childhood. Canal of Nuck cysts or hydroceles often present as fluctuating inguinal masses, commonly misdiagnosed as hernias. Ultrasonography is key for accurate diagnosis, and surgical excision is usually the primary treatment. We present two cases of canal of Nuck cysts in female patients, aged 28 and 32, with no significant past medical history. The 28-year-old underwent surgical excision, while the 32-year-old opted for a watchful waiting approach. Both cases had unremarkable follow-up, with no complications. This report highlights the importance of considering a broad differential diagnosis when evaluating inguinal masses or pain, including canal of Nuck.
