Summary
Rigid spine syndrome, a key feature of autosomal dominant neuromuscular disorder, was diagnosed in two sisters. Muscle imaging revealed severe paraspinal muscle involvement, indicating axial predominance in this condition.
Area of Science:
- Neurology
- Genetics
- Muscle Diseases
Background:
- Autosomal dominant neuromuscular disorders can present with diverse clinical manifestations.
- Rigid spine syndrome (RSS) is a significant clinical feature impacting spinal mobility.
- Previous diagnosis of multicore disease evolved over time in affected individuals.
Observation:
- Two half-sisters presented with RSS as the primary clinical sign of a neuromuscular disorder.
- Initial diagnosis of multicore disease was revised based on long-term follow-up.
- Clinical presentation varied, with axial muscle involvement being a consistent finding.
Findings:
- Long-term follow-up revealed a non-specific muscular dystrophy with axial predominance and RSS in the younger sister.
- The older sister presented with RSS as the sole myopathic sign at age 18.
- Computed tomography (CT) demonstrated severe paraspinal muscle involvement, with minimal or no involvement of other muscles.
Implications:
- This case highlights the diagnostic challenges and evolving nature of certain neuromuscular disorders.
- Severe paraspinal muscle involvement is a key characteristic of this specific autosomal dominant condition.
- Understanding the pattern of muscle involvement can aid in diagnosis and management of rigid spine syndrome.
