[The Leydig-cell testicular tumor. A case report with magnetic resonance images].

OBJECTIVE: An additional case of testicular Leydig cell tumor in a young man is reported. The clinical presentation included gynecomastia and a testicular mass. METHODS/RESULTS: Hormonal studies, testicular US and high resolution MRI were performed before orchidectomy. The histopathological findings were consistent with Leydig cell tumor. A CT scan revealed no metastasis. The patient is clinically disease-free 18 months after orchidectomy. CONCLUSION: High resolution MRI must be performed only when clinic and US findings are discordant.
