This study aimed to summarize an important finding we experienced in our study regarding the MRI features of leydigiomas

In 2 years time, we performed around 130 MRI of the testis for suspected testicular lesions found on a previous ultrasound, all patients underwent surgery within one month from MRI. Of these we included in this study 42 cases in which the Histological diagnosis reported Leydigiomas. We evaluated the Radiologists suggestion based on the evaluation of margins, signal intensity on both T1 and T2 w sequences, and contrast enhancement behaviour( on dynamic acquisition).

In 38/42 cases Radiologists had suggested the presence of Leydigiomas, these lesions presented defined margins, very low intensity signal on T2 weighted sequences and iso-hypointense signal on T1 weighted sequences, moreover these lesions were characterized by an hipervascular pattern with high peak at 1st minute (between 20” and 40”). In 4 cases Radiologists had suggested a Seminomatous origin due to the blurred margins and slow enhancement peak. We achieved a100% sensibility and a positive predictive value of 90%,.  

This study suggest an increasing role for MRI in the characterization of testicular lesions; thanks to the high sensibility, the Radiologist may help clinicians and surgeons to choose the best therapeutic options in favour of a conservative approach instead of a radical orchitectomy, also in light of fertility context.

MRI examination is validated third level method of imaging in a diagnostic algorithm of the testes, which may help to characterize benign lesions in order to avoid radical orchiectomy in young patients and help clinicians and surgeons to choose the best therapeutic options.
