Isolated eye-lid ptosis as initial manifestation of pediatric Behcet's Disease (BD)

PD is an 11-year-old girl first admitted in our hospital with bilateral eye-lid ptosis and headache. She was in good health until one month before the admission; she presented ptosis of eye-lids which was more evident on the left side, without other pathological findings. The normality of the EEG, cranial and midollar MRI, angio MRI, progstigmine test and laboratory tests excluded brain tumors, demyelinating diseases and miastenia gravis. She improved without therapy. After 4 months she experienced folliculitis of the trunk and wrist arthritis. After 8 months she suffered from oral and vaginal aphtosis. BD was diagnosed on the basis of these clinical signs according to the International Criteria. EEG, cerebral SPECT and an ocular examination were performed with normal results; HLA was B51 positive and this is an indicator of BD. Prednisone therapy was started (1 mg/Kg/day) and symptoms greatly improved within 6 months.
