Figure 2: Ultrastructural features. (a) Electron microscopy demonstrating autophagic vacuoles interspersed between the myofibrils (arrows). (b) The contents included cytoplasmic debris, myelin figures (arrow), non-descript electron dense material, and variable amounts of glycogen. (c) The membrane-bound nature of the vacuoles could be appreciated at places (arrow). (d) Extrusion of vacuolar contents (exocytosis) into the reduplicated layers of basal lamina (arrows)
