Behçet's disease (BD) is a rare systemic vasculitis with multisystemic involvement. Neurological involvement, called neuro-Behçet's disease (NBD), mostly involves the central nervous system and cerebral venous thrombosis (CVT) is the predominant neurological manifestation in the pediatric age. A 12-year-old female with a past medical history of a CVT, without an identifiable etiology, was admitted with a five-day right fronto-orbital headache. Neuroimage showed a subacute thrombosis of a right superficial sylvian vein, with indirect signs of intracranial hypertension and no imaging signs of vasculitis. Prothrombotic screening and immunologic study were normal. She was started on acetazolamide and hypocoagulation with progressively improving. She had a history of frequent oral aphthae and an episode of a genital ulcer three months before admission. Pathergy test was negative. HLA-B51 was positive. She was diagnosed with NBD and started therapy with colchicine and infliximab. After discharge, the patient remains without symptoms, hypocoagulated, and on infliximab regimen, without complications to report. This case, only diagnosed in the second episode of CVT, is paradigmatic of the difficulty in establishing the diagnosis of BD.
