RESUMO
Introduction: Dengue fever (DF) is endemic in numerous regions of Indonesia with primary clinical features such as high fever as well as pullout of intravascular fluid and albumin leakage, which provokes pleural effusion, hypoproteinemia, and blood hemoconcentration. However, the incidence of abdominal pain as a clinical manifestation of DF, which refers to acalculous cholecystitis, is rare. Case presentation: An 11-year-old female was admitted to the to hospital with fever, headache, and myalgia. Blood examination resulted in low platelet coua nt and positive IgM Dengue antibody test. On the third day, the patient felt sharp abdominal pain. Abdominal ultrasound showed cholecystitis, cholestasis, pleural effusion, ascites, and laboratory finding showed increased C-reactive protein. The management was conservative and discharged at the 7th day. Discussion: The acalculous cholecystitis in Dengue Fever/Dengue Hemorrhagic fever (DF/DHF) is challenging in diagnose due to atypical presentations. Several proposed mechanisms are critical illness, including direct invasion of the gallbladder epithelial cells, vasculitis, stasis of biliary flow, obstruction of the biliary tree, ischemia, and sequestration. The actual mechanism of the dengue virus has been proposed that direct viral incursion of the gallbladder may yield edema and exudation. Abdominal ultrasonography is considered to diagnose acute acalculous cholecystitis (AAC) in children. Conclusion: Understanding pathophysiology of the acalculous cholecystitis in DF/DHF patients and atypical presentation of sharp abdominal pain help physicians for early diagnosis and management both in monitoring and patient care management. Abdominal ultrasonography can help physicians to diagnose AAC.
