Dermatomyositis masquerading as pulmonary embolism.
A 61-year-old Caucasian was admitted to Department of Chest Diseases and Tuberculosis, Medical University of Bialystok, Poland for progressive muscle weakness and weight loss. Eighteen months prior to admission, the patient had been diagnosed with pulmonary embolism. At that point he was started on Enoxaparin QD. Past medical history was unremarkable. In the interim, the patient developed fever, myalgia and progressive dyspnea. Physical examination on admission revealed a rash on his upper torso and back, and the extensor surfaces of all four extremities. Laboratory values included CPK 8229, MB fraction 219, LDH 981. Chest X-ray and CT scan revealed bilateral patchy consolidations and ground-glass opacities. EMG was consistent with myositis. The patient was started on solumedrol 40 mg i.v., b.i.d., and then switched to prednisone 40 mg b.i.d. His symptoms and muscle strength improved remarkably. The patient was discharged with prednisone with an outpatient follow up.
