Bilobed testis
Bilobed testis, also known as incomplete unilateral polyorchidism, is a very rare variant in children.
On this page:
Pathology
The exact etiology is unknown but is thought to be a form of incomplete polyorchidism. It has been proposed that bilobed testis results from the incomplete division of the urogenital ridge 1-3.
Associations
Radiographic features
Ultrasound
- lobulated testis with normal echotexture
- hemi-testicular structure of similar echogenicity of testis
Treatment
The treatment depends on any underlying abnormality and the evidence is conflicting. Some papers suggest conservative management and imaging follow up (particularly if cancer suspected) 4,5. While others recommend surgical intervention of the affected testis and orchiopexy of the contralateral testis due to the significant risk of testicular torsion 6.
