Hypokalemic quadriparesis: An unusual manifestation of dengue fever.

Dengue is the most important mosquito-borne, arboviral infection found in tropical and sub-tropical climates. Clinical presentation varies from a severe flu-like illness to a potentially lethal dengue hemorrhagic fever. Dengue has been regarded as a nonneurotropic virus. However, there are reports describing neurological involvements in dengue virus infection. The neurological involvement in dengue virus infection includes encephalitis, acute disseminated encephalomyelitis, transverse myelitis, and Guillain-Barre syndrome. The neurological spectrum of dengue patients has been limited because of small number of case reports, paucity of imaging, and neurophysiologic studies. There are only a few isolated case reports and case series documenting acute pure motor quadriparesis in dengue fever. We report acute pure motor reversible quadriparesis due to hypokalemia. Clinicians in the endemic area should be aware of such association of acute pure motor reversible quadriparesis with dengue fever.
