The usual criteria for a diagnosis of PM are weakness in muscles of the head, neck, trunk, upper arms or upper legs; raised blood serum concentrations of some muscle enzymes such as creatine kinase; unhealthy muscle changes on electromyography; and biopsy findings of (i) muscle cell degeneration and regeneration and (ii) chronic inflammatory ...
Myositis is a rarely-encountered medical condition characterized by inflammation affecting the muscles. [2] The manifestations of this condition may include skin issues, muscle weakness, and the potential involvement of other organs. [3] Additionally, systemic symptoms like weight loss, fatigue, and low-grade fever can manifest in individuals ...
Tropical pyomyositis or Myositis tropicans: Transverse T2 magnetic resonance imaging section through the hip region showing abscess collection in a patient with pyomyositis. Specialty: Rheumatology Diagnostic method: Diagnostic method used for PM includes ultrasound, CT scan and MRI.
Inclusion body myositis (IBM) (/ m aɪ oʊ ˈ s aɪ t ɪ s /) (sometimes called sporadic inclusion body myositis, sIBM) is the most common inflammatory muscle disease in older adults. [2] The disease is characterized by slowly progressive weakness and wasting of both proximal muscles (located on or close to the torso ) and distal muscles (close ...
Polymyositis and the associated inflammatory myopathies have an associated increased risk of cancer. [3] The features they found associated with an increased risk of cancer were older age, age greater than 45, male sex, difficulty swallowing, death of skin cells, cutaneous vasculitis, rapid onset of myositis (<4 weeks), elevated creatine kinase, higher erythrocyte sedimentation rate and higher ...

Because different types of myopathies are caused by many different pathways, there is no single treatment for myopathy. Treatments range from treatment of the symptoms to very specific cause-targeting treatments. Drug therapy, physical therapy, bracing for support, surgery, and massage are all current treatments for a variety of myopathies.
Diagnosis is typically based on some combination of symptoms, blood tests, electromyography, and muscle biopsies. [3] Eighty percent of adults with adult-onset dermatomyositis have a myositis-specific antibody (MSA). [5] Sixty percent of children with juvenile dermatomyositis have a myositis-specific antibody (MSA). [6]
