Abstract
Dengue hemorrhagic fever is an acute infectious disease caused by dengue virus. We described the high-resolution CT findings in a 70-year-old male with the disease, which was diagnosed by clinical examination and confirmed by serological methods. High-resolution CT demonstrated bilateral areas of consolidation with air bronchogram and ground glass opacities, as well as small bilateral pleural effusions. Dengue hemorrhagic fever should be considered in the differential diagnosis of diffuse pulmonary hemorrhage.

Dengue fever (DF) is an acute infectious disease caused by dengue virus (DENV)
In a review of the literature, we have found only one report describing the high resolution computed tomography (HRCT) findings in dengue hemorrhagic fever (DHF) [4]
The purpose of this study was to describe the high-resolution CT findings in a patient with dengue hemorrhagic fever, who presented with pulmonary hemorrhage and massive hemoptysis
Summary
Dengue fever (DF) is an acute infectious disease caused by dengue virus (DENV). It is a mosquito-borne flavivirus that belongs to the family Flaviviridae, and consists of four distinct serotypes (DENV 1–4) [1,2]. The purpose of this study was to describe the high-resolution CT findings in a patient with dengue hemorrhagic fever, who presented with pulmonary hemorrhage and massive hemoptysis. A 70-year-old male presented to the Emergency Department with massive hemoptysis for the last 6 hours, respiratory distress, anemia, hemodynamic instability, and renal failure. He had a 6-day history of fever, intense headache, retro-orbital pain, arthralgia, myalgias, and dry cough. Supportive measures were taken and the patient was admitted to the intensive care unit (ICU) and placed on mechanical ventilatory support On examination, he appeared anxious, pale and dyspneic, and inspection revealed ecchymoses over his arms and abdomen. The patient required several blood transfusions, but developed refractory shock, severe metabolic acidosis, and died 15 days after admission
