Extraskeletal myxoid chondrosarcoma (EMC) is aggressive in children. The condition in children differs to that in adults and to skeletal myxoid chondrosarcoma. We report on a 9-year-old girl with EMC in her left thigh. She underwent above-knee amputation. Five months later, a small mass was noted at the right lower lobe of the lung. The patient underwent one course of ifosfamide, carboplatin, and etoposide chemotherapy, followed by resection of the mass and 8 more courses of chemotherapy. At the 2-year follow-up, she was in remission radiologically.

The aging optic nerves and visual cortices were studied in mice. Changes in the morphology of neuroglia were evident in the optic nerve but no difference in the numbers of neurotubules or myelin sheaths optic nerve fibers in the aged were observed. Large myelinated fibers, however, begun to degenerate. In the aging visual cortices, a higher proportion ofden-drodendritic contacts were present and microglia cells were found to be active.

Fat embolism to the lungs and brain is an uncommon complication following fractures. Few reports with descriptions of computed tomographic (CT) findings of emboli to the brain or cerebral fat embolism are available. We report a case of cerebral fat embolism following multiple skeletal fractures and present its CT findings here.
