53-year-old male with severe headache showing left high posterior parietal cystic lesion surrounded by vasogenic edema A, B, C coronal T2, axial T1 and T1 GAD. The lesions show T2 hyper intense core and hypo intense thin rim, T1 hypo intense core and iso intense rim with intense peripheral rim and related meningeal enhancement after contrast administration. D Intermediate echo spectroscopy curve shows relatively depleted Cho, Cr and NAA levels with very high lipid peaks at (0.9–1.3 ppm). E rCBV color perfusion map for the same lesion shows area of relative hypo-perfusion (rCBV = 0.4). F ADC image shows evident diffusion restriction (ADC value measures around 0.68 × 10−3 × mm2/s, collectively the findings are in favor of pyogenic cerebral abscess. Post-operative data confirmed the diagnosis
