Pachymeningitis with pseudo-Foster Kennedy syndrome.
OBJECTIVE
To report a case of pachymeningitis with pseudo-Foster Kennedy syndrome in a patient who was positive for perinuclear antineutrophil cytoplasmic antibody.


METHODS
Case report. A 44-year-old man was examined for headache and diplopia.


RESULTS
Left eye showed limitation of abduction. Ocular fundus, computed tomography (CT), and magnetic resonance imaging (MRI) of the head and orbits were normal. The diplopia subsided spontaneously. Six months later, he noticed sudden visual loss in the left eye. The left eye showed optic disk atrophy and episcleritis, and the right eye showed papilloedema. Computed tomography and MRI exhibited thickened dura mater. Serum perinuclear antineutrophil cytoplasmic antibody level was highly increased.


CONCLUSIONS
Pachymeningitis with ocular involvement sometimes requires repeated CT or MRI for diagnosis. This disorder may be caused by microvasculitis.
