Abstract

Intracranial chondroma is a benign tumor arising from the rests of embryonic cartilages in the dura or dural folds, choroid plexus or the brain parenchyma. It is rare intracranially, but when it does occur, it is predominantly located at the skull base. Among the cohort of intracranial chondroma, the para-falcine location is the rarest. We report a challenging diagnosis and successful management of this rare intracranial para-falcine chondroma in a 53-year-old female patient.

  Fig. 1 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.

  Fig. 3 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 ×100, H&E ×200). C and D: Immunohistochemistry with S100 is positive and Ki67 labels few cells (Immunohistochemistry ×200).
