Figure 6: A 46-year-old female patient with a history of rheumatic heart disease who presented with fever and right hemiparesis; a left centrum semi-oval cystic space-occupying lesion, surrounded by GI vasogenic edema can be seen. (a, b) Axial T2W and T1 GAD: the lesion showed T2 hyperintense core and hypointense rim, with avid peripheral rim enhancement after contrast administration. (c, d) Axial diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) images showed hyperintensity on DWI, with corresponding evident hypointensity within the lesion core on the ADC image (ADC value measured 0.6 × 10-3 mm2/s, reflecting restricted diffusibility). Collectively, the findings are in favor of left focal pyogenic cerebral abscess; postoperative data and post-treatment follow-up confirmed the diagnosis.
