Dengue is an acute mosquito-borne infection caused by dengue viruses from the genus flavivirus. Although viral myositis is common, myositis caused by dengue virus is not commonly reported. We present a case of an 18 year old female with serologically confirmed dengue fever presenting with severe myalgia and lower limb weakness. Twenty fold elevation of serum creatinine kinase level was noted. S...

Inclusion-body myositis is the most frequent and disabling myopathy seen in patients over 50 years of age. The distinct clinical features that lead to correct diagnosis and inclusion-body myositis mimics are highlighted. Inclusionbody myositis has a complex pathogenesis in which autoimmune and inflammatory features coexist with elements of degeneration and abundant accumulations of various stre...

Tropical myositis is a condition characterised by the presence of suppurative lesions within skeletal muscles. There has been little agreement regarding the terminology various names used include purulent tropical myositis, tropical pyornyositis, tropical skeletal muscle abscess, spontaneous bacterial myositis or epidemic abscess. The earliest anecdotal reports of patients presenting both skele...

Idiopathic orbital myositis is an unspecific isolated inflammation of extra-ocular muscles. It is uncommon in children, especially in infants, and is a source of real diagnosis problems. We report the case of a 22 months old infant who was admitted for a sudden swollen eyelid with ptosis and painful bilateral eyes exophtalmos. The orbital computed tomography revealed bilateral and diffuse hyper...

We report an infant case of rotavirus myositis, a rare complication of rotavirus infection. Complement levels of the patient were normal when serum creatine kinase (CK) level was at its peak and then decreased when the CK level became normalized. In a previous case report of rotavirus myositis, transient decrease of serum albumin, immunoglobulin, and complement levels was reported. The authors ...

Parvovirus B19 infection is often asymptomatic, but clinical expressions may include transient aplastic crisis, erythema infectiosum, non-immune hydrops fetalis, and chronic red cell aplasia. This virus has also been associated with rheumatoid arthritis and other autoimmune connective tissue diseases; however, we could not identify any acute adult myositis case developed after a Parvovirus B19 ...

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 ...
