case_images: The Parks three-step test and Hess test (shown in Fig. 1a) were consistent with right 4th nerve palsy. Over the next year, subjective symptoms intensified, consistent with a slow but progressive deterioration of function as recorded in consecutive Hess tests (shown in Fig. 1b). Capecitabine was discontinued, and it was switched to vinorelbine, with subsequent improvement of the clinical picture within 2 months (shown in Fig. 1c).
