A 6-year-old boy presented with facial swelling, laboratory investigation, and bone marrow biopsy revealed acute myeloid leukemia. Head MRI showed bilateral rather symmetrical abnormal marrow signal and expansion of both temporal bones. These show low signal on T1WI (a) and high signal on STIR (b) with appreciable post contrast enhancement (c) and diffusion restriction with low ADC value (d) that is calculated to be 0.560 × 10−3 mm2/s. The picture is of diffuse marrow infiltration of both temporal bones
