Question
My son has had a solid hypoechoic nodule detectable in the right inguinal area since birth. What could this be?
Answer
According to your description, a solid hypoechoic nodule detected in the right inguinal area of a newborn may be a sign of an undescended testicle or congenital unilateral absence of the testicle. It is recommended that you arrange for a medical examination immediately to confirm the diagnosis. If it is an undescended testicle, early surgical treatment is required.
