A minimal myopathy is seen in otherwise normal meat-type poultry. Affected birds show no clinical signs, and their muscles are grossly normal, but microscopically there is mild myofiber degeneration and fat accumulation between myofibers. Focal or multifocal scattered myofibers are hyalinized and mineralized. More severe examples of this lesion contain individual myofiber necrosis, increased fat, and fibroplasia between fibers. No specific cause has been determined for these minimal changes, which have been observed by avian pathologists but are not well described in the literature. Minimal myopathy is not an established name for this condition.
