title: [Diagnostic pitfalls of pseudo-foster kennedy syndrome - a case report].
abstract: To the outpatient facility of the Department of Ophthalmology, Faculty Hospital Brno, Czech Republic, E.U., was in June 2013 referred a 24 years old man with the suspicion of Foster Kennedy syndrome. On the fundus examinations, the findings were in correlation with the symptoms of this syndrome: slightly pale optic disc of the right eye and edema with the anterior extension of the optic nerve head of the left eye. The perimetric examination revealed bilateral visual fields defects, mainly in the nasal parts of the visual fields which is not typical for this syndrome. The native magnetic resonance imaging (MRI) examination was negative. Due to the suspicion of pathologic finding in the visual pathway area, the blood levels of pituitary gland hormones were examined and revealed elevated prolactin levels. In the indicated MRI examination with contrast, in the revised reading, a suspicious microadenoma of the pituitary gland was detected. Due to the atypical changes in the perimetric examinations, other possible causes of visual fields defects as coincidence of multiple, each other independent pathologies (neuritis or neuropathy of the optic nerve, neuromyelitis optica (Devic disease), Lebers hereditary optic neuritis (LHON) etc.) to exclude or to confirm the Pseudo-Foster Kennedy syndrome were taken into account. The patient is regularly followed up at our outpatient facility as well as at the outpatient facility of the Department of Neurosurgery, where, until now, the follow up only was recommended. The diagnosis of this case was, until now, set as Pseudo- Foster Kennedy syndrome, with unclarified cause of the clinical findings.
