Aseptic Abscess of the Spleen as an Antecedent Manifestation of Behçet's Disease.

Behçet's disease (BD) is a multisystem autoimmune vasculitis that manifests as oral and genital ulcers with varying degrees of dermatological and ocular involvement. Aseptic splenic abscesses are a rare entity commonly occurring in autoinflammatory diseases and are rarely associated with BD. Here, we present the case of a 16-year-old male with BD who presented with prolonged fever and constitutional symptoms and was found to have an aseptic splenic abscess. Rapid resolution of the symptoms along with radiological evidence of abscess shrinkage was achieved with corticosteroid therapy.
