FIGURE 4:
A 22-year-old female with pathologically confirmed chordoma. From left to right: T2WI, T1WI, postcontrast T1WI, and signal intensity time course. A lesion with osteolytic bone destruction is seen in C2 vertebrae showing a mild compression of vertebral body. It presents as a mixed signal soft tissue mass intruding into dural sac and spinal cord. The lesion shows a heterogeneous enhancement on postcontrast T1W1. The signal intensity time course shows a clear persistent enhancement pattern with Ktrans = 0.15/min, kep = 0.18/min.
