Foster–Kennedy syndrome (also known as Gowers–Paton–Kennedy syndrome, Kennedy's phenomenon or Kennedy's syndrome) refers to a constellation of findings associated with tumors of the frontal lobe. Although ''Foster–Kennedy syndrome'' is equated with ''Kennedy syndrome'', it should not be confused with Kennedy disease, which is named for William R. Kennedy. ''Pseudo-Foster–Kennedy syndrome'' is defined as one-sided optic atrophy with papilledema in the other eye but with the absence of a mass. ==Presentation== The syndrome is defined as the following changes: * optic atrophy in the ipsilateral eye * papilledema in the contralateral eye * central scotoma (loss of vision in the middle of the visual fields) in the ipsilateral eye * anosmia (loss of smell) ipsilaterally This syndrome is due to optic nerve compression, olfactory nerve compression, and increased intracranial pressure (ICP) secondary to a mass (such as meningioma or plasmacytoma, usually an olfactory groove meningioma). There are other symptoms present in some cases such as nausea and vomiting, memory loss and emotional lability (i.e., frontal lobe signs).〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Foster–Kennedy syndrome」の詳細全文を読む スポンサード リンク
