title: Idiopathic macro-orchidism with testicular lobulation in an adolescent.
abstract: Marked testicular enlargement in the pediatric age group can be caused by many different conditions and is rarely idiopathic. Ultrasound is the primary imaging modality for evaluation of such cases. Bilateral asymmetric idiopathic macro-orchidism with diffuse testicular lobulations is a condition which has not been described before in the literature. We report the clinical, sonographic and histological features of this unusual combination in an adolescent boy.
