Summary:

Description
  • Radiopaedia case ID: 58259
  • Image ID: 38742139
  • Image stack position: 10/29
  • Plane projection: Axial
  • Aux modality: non-contrast
  • Study findings: There is a large extra-axial calcified mass overlying the right frontal lobe. The calcifications have a ring and arcs pattern, which suggests a chondroid matrix. There is an osseous pedicle at the inferior aspect of the mass which is continuous with the superomedial aspect of the right sphenoid wing. There is no hyperostosis or remodeling of the cranial vault. There is moderate mass effect on the adjacent right frontal lobe parenchyma with mild rightward midline shift and compression of the right lateral ventricle (especially the frontal horn). There is no other intracranial or osseous abnormality.
  • Modality: CT
  • System: Central Nervous System
  • Findings: There is a large extra-axial calcified mass overlying the right frontal lobe. It is mostly calcified with expected hypointense signal on T1/T2 within areas of calcifications and diffuse susceptibility artefacts on SWI. It is mildly T1 hypointense, moderately T2 hyperintense (outside of the calcific foci) and demonstrates mild internal enhancement. A small pedicle arising from right greater wing of sphenoid is noted. There is no diffusion restriction. There is no significant intraparenchymal edema and no other abnormal intracranial enhancement. There is moderate mass effect on the adjacent right frontal lobe parenchyma with mild rightward midline shift and compression of the right lateral ventricle (especially the frontal horn).
