Summary:

Description
  • Radiopaedia case ID: 34452
  • Image ID: 11214079
  • Image stack position: 31/32
  • Plane projection: Axial
  • Aux modality: non-contrast
  • Study findings: Non-contrast postoperative scans show right frontal cranioplasty. Deep to this, there is a collection of mixed low attenuation and air with a maximum depth of 7 mm but no appreciable mass effect. Small amount of right frontal lobe low attenuation is longstanding. No intracranial hemorrhage. Ventricular size is normal.
  • Modality: CT
  • 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.
