Follow-up, surgery and proton beam therapy for a pituitary sella chondrosarcoma

 Pituitary chondrosarcomas are rare tumours of cartilage-forming cells arising from the sella, usually presenting as a non-functioning sellar mass  The most important predictor of good long-term outcome is the extent of resection of the initial tumour  However, the anatomical location of these tumours may render complete resection extremely difficult and hazardous to achieve, and proton beam therapy is recommended for any residual  This case demonstrates that these tumours are slow growing  The case also illustrates the importance of histological diagnosis for proton therapy to be offered which is recommended for any residual as it allows safer delivery of significantly higher radiation doses Post-operative MRI 6 months Post-proton therapy FIGURE 1 FIGURE 2
