Neuro-Behçet's Disease Mimicking Low-Grade Glioma Presenting with Drop Foot

Behçet's disease is a multisystem inflammatory disease that manifests with oral–genital ulcers, skin lesions, arthritis, and ophthalmologic and neurovascular findings. Neurological involvement of Behçet's disease is called neuro-Behçet's disease, and it is a difficult entity to diagnose because of insufficient symptoms. We present a 26-year-old male patient with complaints of headache, dizziness, and drop foot in the right lower extremity. He underwent gross total tumor resection with the preliminary diagnosis of low-grade glioma, according to the preoperative magnetic resonance imaging. Histopathological examination and further investigation revealed an interesting neuro-Behçet's disease case because of the localization and clinical occurrence of the lesion.
