The lesion was T1 hypo and T2 hyperintense and demonstrated heterogeneous enhancement on the postcontrast sequences [Figure 1].

Postoperative MRI/CT confirmed gross total resection [Figure 2]. Follow-up MRI showed no recurrence at 1.5 years postoperative [Figure 2].
All slides stained with H and E stain. An image of slide with magnification x400 demonstrate a well differentiated chondroid lesion composed of scattered, relatively bland, stromal cells/chondrocytes. Higher magnification view demonstrate angular and stellate cells set in bluish-pink chondromyxoid stroma. Note that the tumor lacks true hyaline cartilage matrix seen in enchondromas and chondrosarcomas

Pathologic specimens demonstrated a well differentiated chondroid lesion, composed of scattered, relatively bland, stromal cells/chondrocytes [Figure 3].
