Introduction:
An interparietal inguinal hernia is a rare form of hernia. In this type of hernia, the sac passes between the layers of the abdominal wall of the inguinal canal area. Although its treatment is very simple but pre-operative diagnosis is really a challenging issue.
Presentation of case:
A 62 years old male patient presented with complaint of a large swelling over right lower abdomen with absence of right testes since birth. The lump was measured 26×22cm in size. Ultrasonography (USG) and Contrast enhanced computed Tomography (CECT) failed to diagnose as interparietal inguinal hernia which was proved intra-operatively. Few cases have been reported in the medical literature like this.
Discussion:
Exploration revealed the large abdominal lump presenting as an interparietal inguinal hernia. Hernia sac was lying in between external & internal oblique muscles. The right testis was intraabdominal & atrophied. The external inguinal ring was almost completely obstructed.
Conclusion:
An interparietal hernia with undescended testis is a very rare presentation. Even with USG & CT scan diagnosis is very challenging and final diagnosis can be made only intraoperatively.
