Abstract

Dengue, caused by a virus from the Flaviviridae family, remains a significant public health problem, with a substantial increase in the number of cases in Brazil and worldwide. Although the classic form is predominant, visceral manifestations such as encephalitis, hepatitis, and myocarditis are being described more frequently and represent potentially serious complications. Encephalitis is associated with viral neurotropism, manifesting as seizures, altered level of consciousness, and neurological deficits, while hepatitis is related to tropism for hepatocytes and Kupffer cells, causing elevated aminotransferases and a risk of acute liver failure. Myocarditis, although less frequent, can lead to electrocardiographic changes and hemodynamic dysfunction, increasing mortality. Early recognition of these atypical forms, combined with appropriate supportive management and rigorous monitoring, is essential to reduce complications and improve prognosis. This study highlights that, despite advances, the scarcity of information demonstrates the need for further research to clarify the pathophysiological mechanisms, define diagnostic criteria, and guide effective therapeutic strategies.
