Susceptibility-weighted imaging in diagnosing brain capillary telangiectasia: A case report

Abstract

A 65-year-old lung cancer patient was screened for intracranial metastases. Post-gadolinium-enhanced T1-weighted imaging revealed a small enhancing pontine lesion slightly hypointense on T2*-weighted gradient echo, invisible on T1-/T2-weighted imaging. Susceptibility-weighted imaging (SWI) showed marked hypointensity; a small linear hypointensity extension suggested a draining vein. Capillary telangiectasia or transitional capillary-venous malformation was diagnosed. To the best of our knowledge, brain capillary telangiectasia rarely has been previously reported by SWI.Link_to_subscribed_fulltex
