bunina body
"Small granular inclusions (about 1-3 microns in diameter) found in the anterior horn cells, and appearing either singly or in a group. Sometimes they are arranged in small beaded chains. Bunina bodies express cystatin C and consist of electron-dense amorphous material that contains tubules or vesicular structures. The amorphous material frequently includes a cytoplasmic island containing neurofilaments and other micro-organelles."
