Parenchymal neuro-Behçet disease with erectile dysfunction and micturition disturbances: case report and literature review.

Parenchymal neuro-Behçet disease (NBD) is a serious clinic condition with a sub-acute or chronic disease course that results in incapability through pyramidal tract involvement. Though well-known consequences can deter a patient's life, both urinary symptoms and sexual dysfunction are underestimated complications of NBD and closely related in timing. Here, we report the case of a young male patient with parenchymal NBD who developed urinary incontinence and erectile dysfunction in addition to widespread pyramidal tract signs and symptoms. We discuss clinical features, prognosis and treatment of the case. A review of English literature was conducted for cases of concurrent urinary or sexual dysfunction complicating parenchymal-NBD.
