Abstract

Orthostatic hypotension rarely occurs as a result of central vasomotor failure. We report a 74-year-old man who presented with progressive orthostatic dizziness, and intermittent syncope that resulted from a ponto-medullary tumor. Orthostatic hypotension may develop due to the sympathetic failure of the vasomotor center, which is located in the rostral ventrolateral medulla.
