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 isointense on T2-weighted images and inhomogenous enhancement on contrast enhanced T1-weighted images.

Overview

Pelvic MRI may be helpful in the diagnosis of seminoma. On MRI, seminoma is characterized by multinodular tumors of uniform signal intensity.In seminoma fibrovascular septa,indicate with low signal intensity on T2-weighted images and more enhance background tumor on postcontrast T1-weighted images.

MRI

Pelvic MRI may be helpful in the diagnosis of seminoma. Findings on MRI diagnostic of seminoma include:[1][2]

  • Hypointense to normal testicular tissue on T2
  • Visualization of fibrovascular septa, which demonstrate low signal intensity on T2-weighted images
  • Inhomogeneous enhancement on T1 with contrast
