Presentation
Parent complaining that they were unable to feel their baby's testes since birth.
Patient Data
MRI sequences show bilateral two ovoid-shaped masses along the path of testicular descent parallel to the course of gonadal vessels at the inguinal canal level.
They are of intermediate signal in T1 and homogenous high signal in T2 and T2 fat sat. The left testis appears more atrophied.
Empty scrotum is noted on all MRI sequences.
NB: no hypospadias or micropenis.
Case Discussion
MRI is more sensitive than ultrasound in detection of cryptorchidism and its level. Undescended testis appears typically isointense in T1 and homogenous hyperintense in T2, T2 fat sat and STIR.
Usually, contrast is not needed for detection. Atrophic changes of the testis (like decrease in size with decreased T2 signal intensity) and any associated penile deformities should be excluded.
Testes also exhibit strong diffuse restriction on MRI if these sequences feature in local protocol.
