Summary:

Description
  • Radiopaedia case ID: 34452
  • Image ID: 11215508
  • Image stack position: 12/21
  • Plane projection: Axial
  • Aux modality: T2 FLAIR
  • Study findings: Focal rounded extra-axial enhancing mass is seen in the right temporoparietal region, measuring 35mm AP, 28 mm SI and 24 mm transverse. Irregular enhancement is seen in the adjacent brain. Extensive T2 and FLAIR signal abnormality is seen in the white matter throughout the right cerebral hemisphere. Ex-vacuo dilatation related to an old infarct in the right Corona radiata. Encephalomalacia in the anterolateral aspect of the right temporal lobe related to prior surgery. There is a further enhancing 8 x 8.5mm lobulated nodule in this region. Conclusion: Recurrent aggressive appearing meningioma-large nodule with possible brain invasion into the right temporoparietal region and smaller nodule anterolaterally in the right middle cranial fossa.
  • 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.
