noun-modifying (irregular)
Medical term describing a condition or process that is spread out, not localized. Used prenominally (e.g., びまん性の～).
Diffuse lung disease is suspected.
This patient complains of diffuse pain.
diffuse alopecia; diffuse hair thinning; diffuse hair loss
diffuse axonal injury; DAI
Standard medical spelling using 性 for '-ness' or 'nature'.
Rarely used kanji form; 瀰 is not a jōyō kanji.
From びまん (diffuse, spread) + 性 (nature, -ness). The kanji 瀰漫 means 'spreading widely', but the kana form びまん is standard in modern medical usage.
