What infections can cause myositis?

Viruses: Viruses implicated in the pathogenesis of myositis include HIV-1, human T lymphotrophic virus 1 (HTLV-1), influenza, coxsackieviruses, and echoviruses. As in the non–HIV-infected population, HIV-associated polymyositis is most likely autoimmune in origin.

Does an MRI show muscle inflammation?

MRI is sensitive in detecting muscle inflammation, but it is not specific to a diagnosis of myositis because muscular dystrophies and other myopathies may have associated edema on MRI [2]. The signal changes on imaging need to be interpreted in the context of the clinical setting.

Can Mono cause myositis?
