ABSTRACT
Symptoms in the bones, joints and muscles are well-
recognized, albeit rare, clinical manifestations of sarcoidosis.
A recent review cites the prevalence of bone, joint or muscle
involvement in sarcoidosis as 0.9 percent (Dempsey et al.
2009). This low figure almost certainly refers to symptomatic
disease. As shown later in this chapter, plain radiographs and
magnetic resonance imaging (MRI) detect asymptomatic
bony lesions in a larger proportion of patients with
sarcoidosis (Neville et al. 1977; Moore et al. 2005). Never-
theless, musculoskeletal involvement is neither common nor
especially troublesome in most patients with sarcoidosis.
