This paper presents the case of an 8-year-old girl living in Japan who developed pleural effusion during the resolution of dengue fever after returning from Sri Lanka. She was admitted to this hospital with complaints of fever and vomiting. Blood tests revealed decreased white blood cell and platelet counts and elevated liver enzyme levels. Furthermore, there was no increase in hematocrit, but an increase in serum blood urea nitrogen and creatinine levels was observed. An ultrasound image revealed bilateral pleural effusion during the resolution of the fever; therefore, furosemide was administered for two consecutive days, and the patient was discharged on the 8th day of hospitalization.
Dengue virus type 2 was detected in the serum collected on the day before hospitalization. Patients with dengue fever can present with systemic vascular leakage syndrome before or after the resolution of fever, and ultrasonography is a useful technique for monitoring pleural effusion. As the number of pediatric dengue fever cases in Japan is expected to increase in future, it is necessary for pediatricians to understand the clinical symptoms and warning signs of this disease.
