Patient
male, 7 month(s)
 
 
  • Figure 1
    MRI of the head, December 2016, coronal plane

    Post-gadolinium MPRAGE sequence shows solid expansive lesions in both globes withfairly homogeneous enhancement, highly suggestive of bilateral retinoblastoma.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Contrast agent-intravenous; Special Focus: Neoplasia;
     
     
  • Figure 2
    MRI of the head, December 2016, transverse plane

    Post-gadolinium T1 SE: cystic enlargement of pineal gland with partially nodular thick rim enhancement - suspected pineoblastoma.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Contrast agent-intravenous; Special Focus: Cysts;
     
     
  • Figure 3
    MRI of the head, August 2017, transverse plane

    8 months later: Post-gadolinium T1 SE shows significant cyst enlargement from previous examination; partially nodular thick rim enhancement - suspected pineoblastoma.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Contrast agent-intravenous; Special Focus: Cysts;
     
     
  • Figure 4
    MRI of the head, December 2016, sagittal plane

    post-gadolinium MPRAGE sequence shows cystic formation in the pineal region with maximum diameter of 8 mm.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Contrast agent-intravenous; Special Focus: Cysts;
     
     
  • Figure 5
    MRI of the head, August 2017, sagittal plane

    8 months later: post-gadolinium MPRAGE sequence shows enlargement of cystic pineal formation with maximum diameter of 16 mm.
