Cytotoxic Lesion of the Corpus Callosum Caused by Dengue Virus Infection

Abstract

Dengue virus infection can cause a wide spectrum of clinical manifestations, ranging from mild fever to lethal dengue shock syndrome. Neurological manifestations include encephalitis, acute disseminated encephalomyelitis, Transverse myelitis, Guillain-Barre syndrome, and neuro-ophthalmic complications. We report a case of a 44-year-old male who was admitted to our hospital with high-grade fever, myalgia, retro-orbital pain, visual disturbances, and drowsiness. Hematological and serological parameters confirmed the diagnosis of dengue fever. Brain imaging demonstrated altered signal intensity in the splenium of the corpus callosum and eventually a diagnosis of a cytotoxic lesion of the corpus callosum (CLOCC) was made. The patient was managed conservatively and discharged 7 days after admission and imaging findings were resolved completely 3 weeks later.
