An Unusual Presentation of Dengue Fever: Association with Longitudinal Extensive Transverse Myelitis.

Association of dengue fever with transverse myelitis in the form of extensive spinal cord involvement is a rare entity described in the literature. We describe a middle-aged man who presented with dengue fever and in whom weakness of the bilateral lower limbs and urinary incontinence developed on the third day of fever. Magnetic resonance imaging confirmed the diagnosis of longitudinally extensive transverse myelitis. Over a four-week course of corticosteroids with supportive management, the patient recovered without any residual neurologic deficit.
