Abstract
- We report a rare case of chondrosarcoma arising from the dorsum sellae as it mimicked sellar and suprasellar mass. A 36 year-old man visited our hospital for his decreasing visual acuity. Brain magnetic resonance(MR) image revealed round a sellar and suprasellar mass showing mottled enhancement with internal cystic material. The MR image favored the diagnosis of craniopharyngioma, most likely, while plain skull X-ray showed sellar floor erosion and widening, which favored pituitary adenoma. The patient underwent trans-sphenoidal approach less than a week of admission and evaluation because his visual acuity was at a risk of blindness. In the operation, sellar mass was totally removed but some of suprasellar mass was inevitably remained due to limited surgical field. The pathologic diagnosis was chondrosarcoma. Six months from the first operation, pterional approach was performed to remove the remaining suprasellar mass, which didn't come down to sellar area. Intraoperative findings confirmed that the mass was originated from dorsum sellae.
