Cerebral microbleeds ( CMB s) are small foci of (acute, subacute or chronic) blood products, best seen using magnetic resonance imaging ( MRI ) techniques sensitive to iron deposits (i.e. gradient‐echo T2*‐weighted and susceptibility‐weighted imaging), frequently encountered in small vessel disease ( SVD ) (with hypertensive vasculopathy and cerebral amyloid angiopathy as the most frequent conditions) and also in other disorders. In this review, the MRI characteristics of CMB s and the associated MRI abnormalities encountered in common and less common SVD and non‐ SVD conditions are the main focus. Identification of the origin of CMB s depends on their localization, the presence of other associated MRI abnormalities, and the patient's history and clinical state.
