Background: Emery-Dreifuss muscular dystrophy is a rare genetic muscular disease, presenting mainly with contractures, weakness and cardiac conduction abnormalities. Its clinical and laboratory similarities to other muscular dystrophies, and rarity poses diagnostic challenges, requiring a high index of suspicion in resource limited settings.
Case presentation: An 8 year old sub-Saharan male presented with rigidity and deformity of both elbows and ankles, and weakness of the upper limbs and lower limbs for duration of 4 months. This progressed to inability to stand and walk. There was no mental impairment. Physical examination was remarkable for contractures of the elbows and ankles, and wasting of muscles of the limbs and trunk, with a scapulohumeroperoneal pattern, and tachycardia. After laboratory investigations, a diagnosis of Emery-Dreifuss muscular dystrophy was suspected. Physiotherapy was started, wheel chair was prescribed, and referral to a specialist center was done for appropriate management.
Conclusions: Emery-Dreifuss muscular dystrophy is a rare disabling muscular disease which poses a diagnostic challenge. High index of suspicion is paramount for its early diagnoses to prevent orthopedic and cardiac complications. Prompt diagnosis and management is essential to improve on the prognosis of this disease.
