Chondromyxoid fibroma invasion of the transverse-sigmoid sinus junction causing posterior fossa hemorrhage.
We report a 50-year-old woman with a chondromyxoid fibroma of the occipital bone, who presented with a cerebellar hemorrhage due to invasion of the adjacent sinus. Chondromyxoid fibromas are benign cartilaginous tumors. However, this case represents the first example, to our knowledge, of a chondromyxoid fibroma invading the transverse-sigmoid junction, resulting in intracranial hemorrhage. Our report highlights that the location of an intracranial chondromyxoid fibroma is an important factor in guiding surgical management.
