Abstract
Dengue is a common arboviral infection and is one of the tropical diseases which occur in Sri Lanka. Neurological manifestations due to dengue are very rare but can be caused by serotypes 2 and 3. Here we report of an isolated facial nerve palsy occurring as a manifestation of dengue haemorrhagic fever (DHF) in a young boy who presented with fever and constitutional symptoms. Haematological parameters were suggestive of dengue with dengue IgM being positive. Subsequently, he developed right side lower motor neuron type of facial nerve palsy. He was treated with a high dose of steroids and facial nerve stimulation therapy. He clinically recovered without residual weakness.

The neurological complications of dengue virus infection are classified into three categories: metabolic disturbances, viral invasion and autoimmune reactions.[2]
Summary
Dengue is a common arboviral infection and is among the tropical diseases which occur in Sri. Lanka. Neurological manifestations are very rare and are caused by serotypes 2 and 3.1 Encephalopathy, meningitis, acute pure motor weakness, mononeuropathies, transverse myelitis, stroke, acute disseminated encephalomyelitis, Guillain-. Barre Syndrome, hypokalemic paralysis and neuromyelitis optica are the recognized neurological manifestations associated with dengue fever.[2] There were few cases of isolated facial nerve palsy in dengue haemorrhagic fever which had been reported in literature in Sri Lanka.[3] Here we report of an isolated facial nerve palsy occurring as a manifestation of dengue haemorrhagic fever in a young boy
