Introduction
This article presents a rare case report of a canal of Nuck cyst that presented as a femoral hernia and posed diagnostic challenges for physicians. Canal of Nuck cysts are rare congenital abnormalities that can mimic other conditions like hernias.
Case Presentation
A 32-year-old female presented with a reducible bulge in her left groin that increased in size when standing or coughing. Based on the symptoms and location, she was diagnosed clinically with a femoral hernia. However, further investigation revealed it was actually a canal of Nuck cyst.
Diagnostic Evaluation
A tru-cut biopsy was performed which showed a cystic lesion with a thin fibro-collagenous wall lined by simple squamous epithelium, consistent with a canal of Nuck cyst rather than a hernia sac. An ultrasound and CT scan also helped confirm the diagnosis by clearly delineating the anatomy of the cyst.

Treatment
The canal of the Nuck cyst was excised surgically under general anesthesia. The cyst was dissected away from surrounding tissues with careful attention paid to identifying and preserving adjacent structures like nerves and vessels. The excised cyst specimen matched the pre-operative diagnosis.
Follow-Up and Outcomes
The patient had an uneventful post-operative recovery. She was asymptomatic at her one-month follow-up with no signs of recurrence. Canal of Nuck cysts are usually benign but need to be differentiated from other pathologies to ensure appropriate treatment.
Discussion
This case highlights the challenges of differentially diagnosing an obscure condition like a canal of Nuck cyst that can present similarly to more common diagnoses. A high index of suspicion along with adjunctive imaging and diagnostic testing are needed to accurately diagnose these rare cysts. Proper diagnosis is important for selecting the most suitable treatment approach.

A Rare Case Report of a Canal of Nuck Cyst Presented as a Femoral Hernia: A Diagnostic Dilemma
In the field of medicine, hernias are a common occurrence. However, there are certain cases that present unique challenges in terms of diagnosis and treatment. One such case is the presence of a Canal of Nuck cyst, which can mimic the symptoms of a femoral hernia. This article presents a rare case report of a patient who was initially diagnosed with a femoral hernia but was later found to have a Canal of Nuck cyst, highlighting the diagnostic dilemma faced by healthcare professionals.
Case Presentation
The patient, a 45-year-old female, presented with a bulge in her right groin area. She reported experiencing intermittent pain and discomfort in the area for the past few months. On physical examination, a reducible mass was palpated in the femoral region. Based on these findings, a preliminary diagnosis of a femoral hernia was made.
Diagnostic Dilemma
Given the patient’s symptoms and physical examination findings, a femoral hernia seemed to be the most likely diagnosis. However, further investigations were conducted to confirm the diagnosis and rule out any other potential causes. An ultrasound examination was performed, which revealed a cystic structure in the inguinal region. This finding raised suspicions of a Canal of Nuck cyst.

Canal of Nuck Cyst
The Canal of Nuck is a remnant of the processus vaginalis in females. It is a potential space that extends from the round ligament of the uterus into the labia majora. In some cases, this canal can remain open, leading to the formation of a cyst. These cysts are typically asymptomatic, but in rare instances, they can present with symptoms similar to a femoral hernia, causing confusion in the diagnosis.
Treatment Approach
Once the diagnosis of a Canal of Nuck cyst was confirmed, the treatment approach was discussed with the patient. As the cyst was causing discomfort and interfering with her daily activities, surgical intervention was recommended. The patient underwent a surgical excision of the cyst, which was successfully performed without any complications.
Discussion
This case report highlights the importance of considering rare differential diagnoses when faced with a diagnostic dilemma. The presence of a Canal of Nuck cyst mimicking the symptoms of a femoral hernia is an uncommon occurrence but should be taken into consideration, especially in female patients presenting with groin bulges.
Ultrasound examination plays a crucial role in confirming the diagnosis of a Canal of Nuck cyst. It can help differentiate between a cystic structure and a true hernia. Additionally, a thorough understanding of the anatomical structures in the inguinal region is essential for accurate diagnosis and appropriate treatment.

While hernias are a common occurrence, there are certain cases that present unique challenges in terms of diagnosis. The presence of a Canal of Nuck cyst mimicking the symptoms of a femoral hernia is one such rare case. Healthcare professionals should be aware of this diagnostic dilemma and consider it in their differential diagnosis, especially in female patients presenting with groin bulges. Ultrasound examination and a thorough understanding of the anatomical structures are crucial for accurate diagnosis and appropriate treatment.
By sharing this rare case report, we hope to contribute to medical knowledge and raise awareness about the diagnostic challenges associated with a Canal of Nuck cyst.
People Also Ask
What is a cyst on the canal of Nuck?
A cyst on the canal of Nuck is a rare condition that occurs in females. It is caused by the persistence of the processus vaginalis, a tubular structure that extends from the inguinal canal into the labia majora during fetal development. When this structure fails to close properly, it can lead to the formation of a cyst in the canal of Nuck.
What is a femoral hernia in the femoral canal?
A femoral hernia occurs when there is a weakness or tear in the abdominal wall, allowing abdominal contents to protrude through the femoral canal. The femoral canal is a small passageway located just below the inguinal ligament, and it contains important structures such as blood vessels and lymph nodes. When a hernia develops in this area, it can cause a bulge or lump in the upper thigh or groin region.
What is the canal of Nuck?
The canal of Nuck is a vestigial structure in females that is formed during fetal development. It is an extension of the inguinal canal and extends into the labia majora. In males, this structure usually closes off completely, but in females, it may persist and lead to the development of a cyst or hernia.
How do you treat a femoral hernia?
The treatment for a femoral hernia typically involves surgical repair. This is because femoral hernias have a higher risk of complications, such as incarceration or strangulation, compared to other types of hernias. During the surgery, the hernia sac is pushed back into the abdominal cavity, and the weakened area of the abdominal wall is reinforced with sutures or a mesh.
What causes a cyst on the Nuck?
The exact cause of a cyst on the canal of Nuck is not fully understood. However, it is believed to be a result of the failure of the processus vaginalis to close properly during fetal development. This can lead to the accumulation of fluid and the formation of a cyst in the canal of Nuck.
How do you treat a Nuck canal cyst?
Treatment for a cyst on the canal of Nuck typically involves surgical removal. The cyst is excised, and the remaining tissue is sutured to prevent recurrence. In some cases, if the cyst is small and not causing any symptoms, it may be managed conservatively with regular monitoring.
Can a femoral hernia heal without surgery?
No, a femoral hernia cannot heal without surgery. Unlike some other types of hernias, such as inguinal hernias, femoral hernias have a higher risk of complications and are less likely to resolve on their own. Surgical intervention is necessary to repair the hernia and prevent potential complications.
Can femoral hernia be cured without surgery?
No, a femoral hernia cannot be cured without surgery. The only way to effectively treat a femoral hernia is through surgical repair. This is because the hernia sac needs to be pushed back into the abdominal cavity, and the weakened area of the abdominal wall needs to be repaired to prevent recurrence.
What happens if a femoral hernia goes untreated?
If a femoral hernia goes untreated, it can lead to serious complications. The hernia sac may become incarcerated, meaning it becomes trapped and cannot be pushed back into the abdominal cavity. This can cause severe pain, and if blood supply to the herniated tissue is compromised, it can result in strangulation, a life-threatening condition that requires immediate medical attention.
What does the canal of Nuck contain?
The canal of Nuck contains the round ligament of the uterus, which extends from the uterus to the labia majora. In addition to the ligament, the canal of Nuck may also contain fat, connective tissue, and blood vessels.
