摘要

A 56-year old man with past medical history of surgery for congenital pulmonary valve disease, transient ischemic attack without sequelae, meningitis with brain abscess, hyperuricaemia and atrial fibrillation presented with recently increased tiredness, loss of strength and headache. Physical examination revealed dysarthria, and paresthesia in the left hand. No lymphadenopathies, fever, or weight loss were detected. CT-scan of the chest, abdomen and pelvis revealed no abnormalities, and HIV test was negative. On MRI, two intra-axial masses, hyperintense on T1, with contrast ring enhancement in right thalamo-capsular area, and frontal convexity, were visualized (Fig 1a).
