Learning objectives To review the imaging characteristics of cerebral microbleeds (CMBs).To describe the main differential diagnoses.To analyse their clinical relevance, with an emphasis on radiological recognition.
Read more Background MRI examinations from our centre were analysed alongside recent literature.
Read more Findings and procedure details CMBs are seen as punctate hypointense lesions without surrounding oedema, best detected on susceptibility-weighted imaging (SWI).* Chronic small vessel diseaseHypertensive microangiopathyHypertensive microangiopathy is the most common cause of CMBs and reflects chronic damage to small penetrating arteries related to long-standing arterial hypertension. It is frequently associated with other manifestations of cerebral small-vessel disease and has important prognostic implications. [1]Imaging features: Punctate hypointense foci on SWI, without surrounding oedema Predominantly deep distribution Basal ganglia Thalami Brainstem Cerebellum Often associated with: White matter hyperintensities Lacunar infarcts Generalized brain atrophy [fig 1] Cerebral amyloid angiopathy (CAA)Cerebral...
Read more Conclusion Recognising CMBs is essential in radiological practice. Accurate identification and localisation, combined with clinical correlation, help guide the underlying aetiology and estimate vascular risk. Susceptibility-sensitive sequences remain the most reliable tool for their detection and follow-up.
