Summary:

Description
  • Radiopaedia case ID: 79459
  • Image ID: 53020730
  • Image stack position: 12/65
  • Plane projection: Axial
  • Aux modality: Minimum intensity projection (mIP) SWI
  • Study description: MRI brain 7 weeks after surgery
  • Study findings: Findings: Status post excision of left parasagittal cystic meningioma. No obvious enhancing lesion is seen in the excised tumoral bed to suggest recurrence. Postsurgical changes (small focal eccentric subacute hematoma, signs of subacute bleed with hemosiderin deposition on leptomeningeal surfaces of the surgical bed & along the medial aspect of the left parietal lobe, and mild gliotic changes along the medial aspect of the left parietal lobe) are noted in the left parietal lobe. Conclusion: Status post excision of left parasagittal cystic meningioma with no residual/recurrent disease.
  • Modality: MRI
  • System: Oncology
  • Findings: FINDINGS: An extra-axial meningeal based complex solid/cystic lesion is seen in the para-falcine left parietal region. Moderate vasogenic edema around the lesion, mass effect over the body of corpus callosum, and right-sided midline shift of ~ 6 mm are noted. Post-contrast study shows enhancement of the solid component of the tumor as well as the adjacent dura (dural tail sign). MR spectroscopy shows elevated choline and creatine with decreased NAA and elevated alanine peak with increased alanine/NAA ratio. CONCLUSION: Left para-falcine cystic meningioma.
