case_images: Over the next 20 months, the patient's functional status deteriorated significantly due to myopathy as confirmed by electromyography; he developed a restrictive ventilatory disorder based on pulmonary function testing, and erythropoietin-resistant anemia secondary to oxalate deposition as demonstrated on bone marrow biopsy (Fig 3).
