Sporadic inclusion body myositis (sIBM) usually manifests with painless weakness of the hand, finger and hip flexors. Absence of symptoms or signs, but mild hyper-CK-emia as the sole manifestation of IBM, has not been reported. We report the case of a 73-year-old male who presented with asymptomatic recurrent hyper-CK-emia ranging from 200 to 1324 U/L (n<171 U/L), since 10 years. Clinical neurologic investigation, nerve conduction studies and EMG were non-informative. Muscle biopsy surprisingly revealed sIBM. sIBM may be asymptomatic and may manifest with hyper-CK-emia exclusively. So, it has to be included in the differential diagnoses of asymptomatic hyper-CK-emia.
