| History |
A 52 year old former Olympic athlete developed myalgias, cramping, and stiffness in the upper arms, chest, thigh, and calves in 2009 after a blood transfusion for hematochezia attributed to antiplatelet treatment following coronary stenting. Symptoms were worst in the morning, when he could not walk. Simvastatin was stopped without improvement. There was no history of fever, night sweats, or skin lesions and no pertinent family history. Neurologic examination was normal except for increased gastrocnemius muscle bulk and percussion-induced waves of muscle contraction in the calves and thighs. EMG showed infrequent gastrocnemius fasciculations but no evidence of neuropathy, myopathy, or myositis. Percussion- induced muscle contraction was not electrically silent. Paraneoplastic panel demonstrated elevated striated muscle and acetylcholine receptor antibody titers, but single-fiber EMG did not demonstrate increased jitter or blocking. There was a high CPK (500), slight elevation in liver enzymes, and low 25-hydroxy vitamin D. CBC, vasculitis panel, myositis antibody profile, ESR, CRP, hepatitis screening, HIV, SPEP/UPEP, B12, and thyroid studies, CT of chest, abdomen, and pelvis and caveolin-3 (CAV3) genetic testing were normal. A 7-day trial of prednisone 20mg/day did not improve CPK elevation or cramping. Four months later, the patient developed diplopia and was sent for neuro-ophthalmologic examination. |
