Churg-Strauss syndrome presented as Pseudo-Foster-Kennedy syndrome: a case report
Main Article Content
Abstract
A 52-year-old woman with bronchial asthma, frequent sneezing, and a skin lesion has suddenly developed poor
vision for 15 days in the left eye. Her presenting vision was 6/18 and perception of light was positive in the right
and left eyes, respectively, with mild pallor in the right optic disc and disc swelling in the left eye. She had a high
eosinophil count, positive ANCA, and a skin biopsy in favor of Churg-Strauss disease. The patient was diagnosed
with left optic neuropathy as a result of arteritis, which is a component of Churg-Strauss syndrome (CSS), and was
treated with Inj. Methylprednisolone pulse therapy, followed by oral prednisolone but preceded to no perception of
light in the left eye after 7 days of follow-up. Although CSS is a rare disease, routine checkup by an ophthalmologist
can save vision and identify the high-risk group for proper referral to prevent unwanted morbidity and mortality.
