Sarcocystis nesbitti infection
Diagnosis is made by examining stool (looking for sporocysts or oocysts). Magnetic resonance imaging of affected muscle may show findings consistent with myositis. Muscle biopsy may show the organisms on histopathologic examination. Laboratory studies are not specific, but eosinophilia may be present.
There are no conclusive recommendations for treatment, and in most cases symptoms improve without therapy.
