Pseudo-Foster Kennedy syndrome

Case contributed by Dr Ammar Haouimi


Sudden vision loss of the right eye with papilledema on the ophthalmological exam. The patient describes the same history on the left side 4 years ago.

Patient Data

Age: 35 years
Gender: Male

Brain and cervical spine MRI

Swelling with high signal intensity and contrast enhancement of the retrobulbar intra-orbital segment of the right optic nerve. The left optic nerve appears atrophied mainly at its proximal and mid-portions (diameter = 1.3 mm). No demyelinating lesion was seen at the infra- or supratentorial level.

No spinal cord lesion is seen.

Case Discussion

MRI appearances of right optic neuritis with contralateral optic nerve atrophy (Pseudo-Foster Kennedy syndrome).

The unilateral optic neuritis, the absence of a spinal cord lesion as well as the clinical presentation make neuromyelitis optica (NMO) much less likely.
