Abstract

Objectives

The aim of this prospective study is to investigate the central nervous system involvement in Crimean-Congo haemorrhagic fever (CCHF) with magnetic resonance imaging (MRI) in conjunction with clinical and laboratory findings.

Methods

Between July 2015 and August 2016, 36 patients with CCHF were undergone brain MRI including SWI. Two MRIs, one at the time of admission and the second in the convalescent period, were performed for each patient in order to see if there is any sign of central nervous system (CNS) involvement, especially in terms of intracranial haemorrhage or viral encephalitis. Clinical severity scoring was also done and laboratory findings were noted in order to correlate with clinical and imaging findings.

Results

None of the 36 patients showed any MRI findings of an acute intracranial event during the course of the disease. There was a significant difference between mild cases and moderate cases in terms of some laboratory parameters (p < 0.05).

Conclusions

Although CCHF is a highly lethal disease which involves multiple organs and systems, CNS involvement seems to be extremely rare in mild and moderate cases.

Key Points

• MRI is the imaging method of choice to diagnose microbleeds and encephalitis

• Although CCHF causes multisystem bleeding, intracranial haemorrhage seems to be very rare

• CNS complications are uncommon, even in the setting of suggestive symptoms

• Death usually results from extracranial bleeding and multiorgan failure

• Severity scoring is associated with some laboratory abnormalities in CCHF
