Her biopsy revealed multifocal rhabdomyolysis with myofiber necrosis and absence of phosphorylase staining consistent with McArdle disease (type V glycogenosis) (Fig.
Following the diagnosis, a nutritionist was consulted, who stated that diet had no role in the patient's McArdle disease.
Staining with phosphorylase stain showed no activity, establishing the diagnosis of McArdle disease, as seen in Figure 3 and Figure 4.
