This report describes a rare case of recurrent bilateral focal myositis and its successful treatment via methotrexate. A 38-year-old man presented myalgia of the right gastrocnemius in May 2005. Magnetic resonance imaging showed very high signal intensity in the right gastrocnemius on short-tau inversion recovery images. A muscle biopsy revealed inflammatory CD4+ cell-dominant myogenic change. ...

Rotavirus and norovirus are common pathogens associated with gastroenteritis in children. Although rotavirus occasionally induces central nervous system disease, only 3 cases with rotavirus-induced acute myositis have been reported in the English literature. We recently treated a female patient with acute myositis associated with gastroenteritis induced by concurrent infection with rotavirus an...

We describe six elderly cases of acute myositis with type A influenza virus infection (Sydney) during the 1998-1999 outbreak. All six cases suffered from myalgia or muscle weakness especially in the lower extremities and the serum creatine kinase (CK) values were elevated above 1,000 IU/l without MB isoenzymes or electrocardiogram abnormalities. There have been a few case reports of acute myosi...

BACKGROUND Fractures of the clavicle are common injuries. The complications have been well documented in the literature. CASE PRESENTATION Despite it close proximity to the sternocleidomastoid muscle and myositis ossificans recognised as a known complication of any fracture, the two have never previously been described in association secondary to a fracture of the clavicle. We present a case ...

The idiopathic inflammatory myopathies are chronic autoimmune disorders sharing the clinical symptom of muscle weakness and, in typical cases, inflammatory cell infiltrates in muscle tissue. During the last decade, novel information has accumulated supporting a role of both the innate and adaptive immune systems in myositis and suggesting that different molecular pathways predominate in differe...

experience in treating patients with myositis and are active in research, both clinical and fundamental, about myositis. The Neuromuscular Centre Nijmegen has an extensive collaboration with the departments of rheumatology, dermatology, and internal medicine, and through this collaboration the authors are familiar with the different viewpoints about diagnostic criteria, treatment, etc, for myos...

The computed tomographic (CT) scans of 11 consecutive patients with orbital myositis were reviewed to better characterize the CT appearance of this condition. The findings in this series differed from those of previous reports in several ways. Multiple muscle involvement predominated. Bilateral involvement was more frequent than previously reported. Enlargement of the tendon as well as the musc...
