Severe Dengue Hemorrhagic Fever: Imaging Findings and Clinical Management

Abstract

Dengue hemorrhagic fever (DHF), a severe manifestation of dengue virus infection, poses significant challenges due to its diverse clinical presentations and rapid progression. Radiologic imaging plays a crucial role in the early identification and management of severe complications associated with DHF, such as plasma leakage, internal bleeding, and organ impairment. Common imaging modalities, including ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI), are employed to detect pleural effusions, ascites, gallbladder wall edema, and organomegaly. Early and accurate imaging findings contribute significantly to clinical decision-making, helping to stratify patient risk, monitor disease progression, and guide therapeutic interventions. This review summarizes characteristic imaging findings observed in severe DHF, discusses their clinical significance, and outlines current management strategies aimed at reducing morbidity and mortality.
