Purpose Frosted branch angiitis (FBA) is a disorder characterized by acute panuveitis with vasculitis. It is a rare disorder (just 60 cases worldwide published) which is slightly more frequent in males especially in the third decade of life. Methods a 28 year‐old female was admitted due to suspected meningitis associated to visual loss in both eyes (OU). One week before, she was diagnosed of bacterial tonsillitis and got several antibiotic drugs. The admitted patient started empirical treatment with: Ceftriaxone IVand Acyclovir IV. Lab test, serologies and CT scan did not disclose any abnormality. Latex agglutination test for Neisseria meningitidis was negative, however intracellular lised bacterias were seen through the microscope informed like compatible with that agent. The patient also presented decreased visual acuities(VA): right eye (OD) 20/200 and left eye (OS) 20/120 and panuveitis in OU. Funduscopically it was seen a frosted branch angiitis in OU. Due to her antibiotic and viral therapy, Prednisone 1mg/Kg PO was added. Three weeks after, the patient left the Hospital on Famciclovir 750mg QID, Ciclosporine 300mg daily and tapering Prednisone. Results One year later, the patient has 20/20 of VA in OU and is off of any treatment. Conclusion FBA may disclose three conditions: an infiltrating vessels by malignant cells, a sheathing vessels secondary to an active disorder or subsequently to a previous inflammation disease. This case may be included within that last term due to an aseptic meningitis by N. meningococcus. Recognition of what kind of FBA clinical sign is will be essential to establish one certain diagnosis and the subsequently treatment. [ABSTRACT FROM AUTHOR]
