Similar to CSF1R-ALSP, white matter lesions were the most common finding on neuroimaging (in 100% of BANDDOS vs. 81% with CSF1R-ALSP cases), followed by calcifications (in 83% of BANDDOS vs. 75% with CSF1R-ALSP cases) and callosal abnormalities (agenesis in 75% of BANDDOS vs. atrophy in 29% with CSF1R-ALSP cases) [18]. This evidence concerns the gene CSF1R and Hereditary diffuse leukoencephalopathy with axonal spheroids and pigmented glia.
