A 16-year-old girl presented at the emergency unit with myalgia following a flu-like episode. Laboratory tests indicated severe rhabdomyolysis and nephritis. Autoimmune-induced myositis was excluded on the basis of negative tests for antinuclear antibodies; prednisolone treatment was discontinued 1 week later. The patient recovered gradually and was discharged with physiotherapy 2 weeks later. High positive titres of complement-binding antibody against influenza B virus were found, i.e. 1:125 and 1:250 on days to and 25 of illness, respectively. Viral myositis is an uncommon disease entity that occurs following a viral infection, especially with influenza virus, that has been experienced for the first time. It usually runs a benign course: children often present with calf tenderness that resolves within a few days. There are cases, however, with a more serious course involving severe rhabdomyolysis and acute renal failure that can be sometimes fatal.

Introduction. Whilst there are reports of viral myopathies affecting children and the immunocompromised, infective myositis is a relatively rare inflammatory myopathy in adults. The clinical spectrum can range from benign myalgias to more serious complications in certain risk groups. Case Presentation. We present two cases of myositis as a result of parvovirus B19 infection. Conclusion. Viral myositis and parvovirus B19 associated myositis should be considered in adults presenting with significant myalgia.

Acute viral myositis is a rare condition that is commonly defined with influenza A, B, and enterovirus in the United States of America. Viral myositis complicated by rhabdomyolysis is even less common but requires prompt attention and diagnosis to prevent complications. We describe the occurrence of acute viral myositis complicated by rhabdomyolysis in a young 43-year-old man that lead to acute renal failure. It also highlights that clinicians should keep in mind that viral upper respiratory infections can be complicated with various clinical manifestations that could extend beyond respiratory symptoms.
