Summary:

Description
  • Radiopaedia case ID: 34452
  • Image ID: 11219294
  • Image stack position: 36/124
  • Plane projection: Axial
  • Aux modality: T1
  • Study findings: Comparison is made to prior examinations. No evidence of recurrence of the right middle cranial fossa meningioma – some minor post-operative meningeal enhancement lies deep to the craniotomy. Moderate gliosis involves the lateral right temporal lobe as well as the frontal operculum. Cerebral parenchymal signal intensity in architecture, and ventricular volume is otherwise stable. Conclusion: Stable appearances - no evidence of tumor recurrence.
  • Modality: MRI
  • System: Oncology
  • Findings: Erosion of the lateral aspect of the right greater wing of sphenoid and adjacent squamous temporal bone is noted. Aggressive regional periosteal reaction is noted in the region. Associated with this is a contrast-enhancing irregular shaped extra-axial mass conforming to the contour of the sphenoid wing. This is a solitary lesion. There is moderate underlying vasogenic edema. No midline shift. Basal cisterns are not effaced. Conclusion: Aggressive extra-axial mass centered on the right sphenoid wing with osseous invasion. Atypical meningioma is favored with invasive dural metastasis (e.g. prostate primary) remaining a differential.
