Many inclusion body myositis (IBM) patients have been misdiagnosed as amyotrophic lateral sclerosis (ALS). We report a case of IBM coexisting with familial ALS.
Clinically, Inclusion body myositis (IBM) patients have been misdiagnosed as amyotrophic lateral sclerosis (ALS). Recent studies have shown that mutations of valosin-containing protein (VCP) are involved in ALS and IBM. ALS and IBM may share similar pathogenesis of multisystem proteinopathy. We report a case of sporadic IBM coexisting with familial ALS (fALS).
