myopathy affecting proximal and distal musculature with typical onset of symptoms after age 50 years. Inclusion body myositis more often affects males and results in a classical pattern of early asymmetric weakness and wasting of forearm flexors (wrist and long finger flexors), quadriceps and ankle dorsiflexors.

The distinct clinical features that lead to correct diagnosis and inclusion-body myositis mimics are highlighted.

متن کاملInclusion Body Myositis
Inclusion body myositis is an insidious, slowly progressive myopathy of middle-aged and older individuals. Because of these characteristics, diagnosis is often delayed. Affected muscle is marked by the presence of rimmed vacuoles, inclusions, and an inflammatory infiltrate largely made up of CD8 T lymphocytes and macrophages. The inclusions contain beta-amyloid and phosphorylated tau protein, a...
متن کاملInclusion body myositis.
The histochemical and ultrastructural study of muscle biopsies of two patients with a chronic muscle weakness and wasting showed particular changes in muscle fibers: (1) peripheral lined vacuoles, containing whorls of membranes and cytoplasmic debris; (2) collections of intranuclear and intrasarcoplasmic tubular filaments (16-18 nm in external diameter and 6.5 nm in inner diameter). These chang...
