A rare presentation of dengue fever: bilateral psoas muscle hematoma, intrahepatic cholestatic hepatitis, pancreatitis and pancytopenia.

Dengue is the foremost cause of arthropod-borne viral disease in the world. It is and commonly found in tropical and subtropical parts of the world. Dengue fever is caused by one of the four distinct serotypes (DENV 1-4) of single-stranded RNA Flavivirus genus and transmitted through Aedes mosquito. Infection caused by one serotype develops lifelong immunity to that serotype, but not to others. Dengue fever (DF) presents with high fever, headache, myalgia, and arthralgia, and rash. Severe dengue, dengue haemorrhagic fever (DHF), and dengue shock syndrome (DSS) are accompanied by thrombocytopenia, vascular leakage, and hypotension. DSS is characterized by shock, which can be fatal with case fatality high as 12% to 44%. There are few atypical manifestations of dengue fever growing with rising disease burden, often missed and sometimes difficult to diagnosis. In this case report, we will discuss atypical manifestations of bilateral psoas muscle hematoma, intrahepatic cholestatic hepatitis, pancreatitis and pancytopenia observed in dengue fever patient.
