Miopatía como presentación infrecuente de acromegalia

Myositis or inflammatory myopathy is a common but little-studied feature of acromegaly, characterized by predominantly proximal weakness that can be accompanied by muscle pain. Findings supporting a diagnosis of myositis are an increase in muscle enzymes, altered electromyography and characteristic biopsy results. We report the case of a patient who presented with muscle weakness. Complementary investigations revealed myositis and, after other causes were ruled out, a diagnosis of acromegaly was established. Myositis as the main manifestation of acromegaly is exceptional.
