Abstract:
Bone formation within the choroid plexus papillomas is rare, with only 4 previous cases reported. We present a case of a 12-year-old boy who presented with papilledema, visual loss and hydrocephalus who was found to have a choroid plexus papilloma. Histological analysis of the tumor revealed foci of cancellous bone formation with hematopoietic cells within the marrow spaces. We review the proposed mechanisms for bone formation within neuroepithelial brain tumors.
