A case of crimean congo hemorrhagic fever complicated with pararenal abscess

Abstract

Introduction: Crimean-congo hemorrhagic fever (CCHF) is a tick-borne zoonotic disease caused by Nairovirus of the Bunyaviridae family. It affects multiple systems and case fatality rate may vary between 5% - 30%. It also causes several complications. Here we presented a pararenal abscess case complicating CCHF, never reported before. Case Presentation: A 49-year-old male dealing with livestock husbandry was admitted to Ankara Training and Research Hospital with three days of complaints including fever, malaise, headache, myalgia, nausea, vomiting, diarrhoea and hematuria. Laboratory findings (thrombocytopenia and elevated alanine transaminase (ALT) and aspartate transaminase (AST)) were suggesting CCHF and he was hospitalized. The diagnosis was confirmed by CCHF reverse transcriptase-polymerase chain reaction (RT-PCR) and IgM positivity. Although his clinical condition was improving, he developed right flank pain on the fourth day. The computerized tomography showed abscess (pararenal 44 mm * 17 mm). With appropriate antibiotherapy and percutaneous drainage, his clinical and laboratory findings regressed. Conclusions: Unexpected complications may be seen during the course of CCHF. Patients must be closely followed up.
