case_images: a A CT scan showed an osteolytic process. On MRI without (b) and with (c) contrast, the tumour was hypointense and showed contrast enhancement. On clinical appearance, the tumour was not visible or palpable, neither before (d) nor after surgery (e). Intraoperative appearance of the tumour located inside the orbital rim (f), and appearance of the non-encapsulated and friable CMF (g). Histology showed spindle cells (chondroblasts) in a myxoid stroma (HE; bar = 100 mum) (h) and in alcian blue, the myxoid stroma stains blue, while the nuclei are red (alcian blue; bar = 100 mum) (i). CMF, chondromyxoid fibroma.

case_images: The mass was 15 mm in diameter at its largest, was irregular, and showed enhancement after injection of Gadolinium in the form of Gadovist  (shown in Fig. 1). The diagnosis of CMF was based largely on the morphological appearance (shown in Fig. 1).
