A 38-year-old male patient with a history of hypertension presented with left hemiplegia, hemianaesthesia and hemianopia. MRI of the brain showed anterior choroidal artery (AchA) territory infarct (figure 1). MRI brain angiography and 2D echo were normal. Serum fasting lipid profile, sugar levels, thyroid studies, serum homocysteine levels and antinuclear antibody (ANA), double-stranded deoxyribonucleic acid (DsDNA) and antiphospholipid antibody (APLA) were negative. Trans-oesophageal echocardiography and Holter monitoring were normal. Workup for sickle cell anaemia was negative.
