Abstract
BACKGROUND: Hantavirus infection is worldwide epidemic and can cause life-threatening consequences. With more and more cases reported in countries with atypical morbidity, it is necessarily urgent to know some atypical symptoms and signs of Hantavirus infection. CASE PRESENTATION: Here we report the case of a 44-year old male with a complaint of fever and diffuse abdominal pain, initially suspiciously diagnosed with acute peritonitis. The patient was eventually diagnosed as hemorrhagic fever with renal syndrome and enhanced CT scan showed peritonitis. The clinical condition of the patient was relatively mild and he was recovered 9 days later. CONCLUSION: Peritonitis secondary to hemorrhagic fever with renal syndrome is rare in clinically practice. When confronted with atypical celialgia, it is important to make differential diagnosis of hantavirus infection.
