case_images: Radiological features of the tumor. A-C: Preoperative MRI reveals a T2 weighted hypointense lesion, showing peripheral rim and central foci of enhancement on postcontrast scan. It is abutting the superior sagittal sinus and is attached to the falx. D-F: Postoperative MRI revealing postoperative changes in the tumor bed in the form of hemosiderin ring and adjacent gliosis, along with complete excision of the lesion without any injury to the superior sagittal sinus.

case_images: Histopathology. A and B: Cartilagenous tumor showing mature chondrocytes in the lacunae. Background shows chondroid material interspersed with areas of hyalinised to myxoid areas (H&E x100, H&E x200). C and D: Immunohistochemistry with S100 is positive and Ki67 labels few cells (Immunohistochemistry x200).
