Axial (top row) and sagittal (bottom row) MR-images of the intra-axial cystic lesion (indicated by the white solid arrows) located in the left part of the medulla oblongata over the course of 2 months. MR-images were obtained on day 2, 6, 7, 10, 15, 24, and 62 after symptom onset as indicated on the single MR-images. Whenever available, T1-weighted contrast-enhanced MR-images were selected for both axial and sagittal images [day 2, 6, 10, 15, 62 (only sagittal image)]. For the other MR-sessions, either T2-weighted (day 7) or gradient-echo T1-weighted [day 24 and 62 (only axial image)] MR-images were selected. Over the course of disease growth [from 16 x 5 x 4 mm on day 2-25 x 11 x 9mm on day 10 (height x depth x width)] and contrast-enhancement (first noted on day 6) of the cystic lesion can be depicted. After treatment initiation with dexamethasone (day 9) and surgical preparation of the solid lesion (day 15), the size of the cystic lesion decreased continuously and could not be detected any more on day 62.
