Primary Dengue Fever with Acute Transverse Myelitistion of Determina

We hereby report a first infantile case of primary dengue fever with acute transverse myelitis. An 8 month girl presented as a case of acute febrile encephalopathy with hepatomegaly. Investigations showed thrombocytopenia, positive IgM for dengue and normal liver echotexture on ultrasonography. During hospital stay she developed paraplegia with no signs of abnormal hemostasis or plasma leakage. MRI showed signs of acute tranverse myelitis at T8-T12 spinal level. This is first infantile case of primary dengue fever with acute tranverse myelitis to be reported. Autoimmune demyelination and direct viral invasion are suggested pathophysiological mechanism.
