Summary:

Description
  • Radiopaedia case ID: 34452
  • Image ID: 11217004
  • Image stack position: 3/20
  • Plane projection: Axial
  • Aux modality: FLAIR
  • Study findings: Recent right temporoparietal craniotomy noted, with resected posterolateral right temporal convexity tumor, compatible with stated meningioma invaginating/invading the temporoparietal junction. Subtle fluffy ill-defined parenchymal enhancement marginates the posterior and medial margins of the gliotic cavity, with trace parenchymal tumor residuum not excluded. The separate 5-6 mm enhancing extra-axial tumor nodule, centered laterally in the right middle cranial fossa, remains stable. Of note, a large area of diffusion restriction, consistent with infarction, has developed inferiorly and posteriorly in the right MCA territory amongst extensive pre-existing right cerebral vasogenic edema and gliosis, with no overt positive mass effect demonstrated.
  • 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.
