Illustrative 3 T MRI slices of the patient’s cervical spine. C1–Th2 are in sagittal (A T2w TSE and C T1w TSE with fat-saturation and after iv application of GBCA) and coronal orientation (B short tau inversion recovery [STIR]). Representative transversal slices at the C4 level are depicted in D (T2w TSE) and E (T1 fs TSA with iv GBCA). Long-range (C2–C6) T2-signal increase of the anterior horn of the myelon (white arrows) with subtle corresponding contrast enhancement (white arrowheads)
