Overview

Pelvic MRI may be diagnostic of testicular seminoma. On MRI, seminoma is characterized by multinodular tumors of uniform signal intensity. Findings on MRI suggestive of seminoma include hypo- to isoinytense on T2-weighted images and inhomogenous enhancement on contrast enhanced T1-weighted images.

MRI

• Pelvic MRI may be diagnostic of testicular seminoma.
• On MRI, seminoma is characterized by multinodular tumors of uniform signal intensity.
• Findings on MRI suggestive of seminoma are tabulated below:

MRI component	Findings
T2	Hypointense to normal testicular tissue
T1 with contrast	Inhomogeneous enhancement
