Treatment

Muscle sarcocystosis can be suspected in persons with signs and symptoms of myositis, with or without fever. Ill patients may have an elevated eosinophil count and may have an elevated creatinine kinase with no other explanation for these findings. A muscle biopsy can be done using conventional histologic staining and will show eosinophilic myositis but may not demonstrate classic sarcocysts. Molecular testing is not widely available. Albendazole was reported to be efficacious in one case of muscular sarcocystosis (Arness et al., Am J Trop Med Hyg 1999;61:548-53). Corticosteroids may provide symptomatic relief in cases of muscular sarcocystosis.
