T1W, T2W, FLAIR, DWI, GAD, MRV, and MRA sequences) performed on the 15th day of poisoning showed bilateral, symmetric, ill-defined, heterogenous T2 weighted (T2W), and fluid attenuated inversion recovery (FLAIR) showed heterogenous (high with patchy central low) signal abnormality in striato-capsular areas of basal ganglia with thalami sparing (Figures 3-5). The low-intensity areas seen in T2W and FLAIR sequences showed intermediate signal intensity in T1 weighted (T1W) and blooming on susceptibility weighted imaging (SWI), with no enhancement of contrast, suggesting evidence for bilateral, symmetrical haemorrhage with associated vasogenic oedema involving basal ganglia and internal capsule (Figures 6 and 7).
