In the following pictorial review, common and uncommon neurovascular complications associated with a spectrum of viral, bacterial and fungal infections involving the central nervous system will be illustrated. These complications include cerebral vascular insult, venous thrombosis, vasculitis and aneurysm formation. They can occur as separate entities but are often inter-related. The imaging features of neurovascular complication related to infections can provide clues and aid diagnosis when considering the potential mode of infectious spread and the type of potential infectious organism involved. The radiological appearances vary from common features that are shared by several types of pathogens to typical characteristics of a type of infectious organism.
