Acute acalculous cholecystitis secondary to dengue fever

Patients with dengue fever usually present with typical symptoms such as fever, frontal headache, retro-ocular pain, myalgia, arthralgia, nausea, vomiting, rash, leucopaenia and thrombocytopaenia. However, they can also manifest with atypical symptoms. Acute acalculous cholecystitis is an atypical manifestation of dengue fever. In dengue endemic areas such as Brunei Darussalam, it is imperative that typical and atypical presentations of dengue fever are recognised so that early diagnosis can be made. We report a case of an 18-year-old Malay lady who presented with fever, cough, abdominal pain, and generalised myalgia. She was found to have acute acalculous cholecystitis secondary to dengue fever.
