Neuro-Sweet Disease Causing Orbital Inflammation.

Neuro-Sweet disease is a rare condition causing encephalitis or meningitis in addition to the erythematous skin plaques of Sweet syndrome. Neuro-Sweet disease has been associated with several ocular manifestations, including ocular movement disorders, episcleritis, conjunctivitis, uveitis, and optic disc oedema. The author reports a patient with orbital inflammation, cranial neuropathies, and a skin rash in the setting of myelodysplastic syndrome. Biopsy of her skin lesion confirmed the diagnosis of neuro-Sweet disease. To the author's knowledge, this is the first reported case of neuro-Sweet disease causing orbital inflammation. Her ocular inflammation resolved with the use of systemic corticosteroid treatment.
