Imaging Findings of Angiomyxolipoma of the Spermatic Cord Mimicking Inguinal Hernia

We report the case in a 72-year-old man who presented with a right inguinal mass and with a one month history that was initially interpreted as an inguinal hernia. Ultrasonography (US) and computed tomography (CT) demonstrated a right inguinal mass, including myxoid and fat component, extending from the right spermatic cord to the right inguinal subcutaneous layer. Mass excision was performed, and the diagnosis turned out to be angiomyxolipoma. Angiomyxolipoma is a rare tumor and the preoperative diagnosis of this disease is very difficult. However, angiomyxolipoma of the spermatic cord should be considered in the differential diagnosis in patients with an irreducible inguinal mass. Imaging diagnosis, such as US and CT may help to make a preoperative diagnosis.
