A Case of Interparietal Inguinal Hernia with Cryptorchidism in an Adult

Abstract

An 84-year-old man was admitted to a local clinic for bulging of the right inguinal region. The patient was diagnosed with right inguinal hernia and referred to our hospital. On palpation of the right scrotum, the right testis could not be identified. Computed tomography (CT) revealed a small solid mass, considered the right testis, within a right inguinal hernia. Hence, the patient was diagnosed with right inguinal hernia with cryptorchidism and operation was performed. The hernia sac was protruding through the right internal inguinal ring and was between the external oblique muscle and subcutaneous fat layer instead of extending down into the inguinal canal. The small right testis was found in the hernia sac. Based on these intraoperative findings, the patient was diagnosed with interparietal hernia with cryptorchidism. Orchidectomy was performed owing to the possibility of testicular cancer in addition to hernioplasty (Marcy method).

Inguinal hernia with cryptorchidism in adults is rare. Additionally, interparietal inguinal hernia is considered a rare variant of inguinal hernia. To our knowledge, this is the first case report of interparietal inguinal hernia associated with cryptorchidism in an adult in Japan.
