Rare clinical syndrome in which an anterior intracranial mass directly compresses the ipsilateral optic nerve, causing atrophy, and increases intracranial pressure, which results in contralateral papilledema.
The syndrome was first extensively noted by Robert Foster Kennedy in 1911, an Irish neurologist, who spent most of his career working in the United States of America. However, the first mention of the syndrome came from a William Gowers in 1893. Schultz–Zehden described the symptoms again in 1905. A later description was written by Wilhelm Uhthoff in 1915.
