Transverse image of the scrotum. The structure on the right side has an echogenicity that is slightly higher than the 2 normal testes.

Although the structure has the size of a testis and it is vascularized, it is not a third testis. During compression the structure was soft. The structure was not present during childhood and had developed over the last months. Because of its aspect and structure we concluded that the third structure was probably a lipoma. This was confirmed during surgery
Conclusion 2 normal testis and a lipoma resembling a third testis
