Case Report (n=1)

Structured PICO

P
Population
A six-month-old intact male Pomeranian dog presenting with progressive exercise intolerance, severe disuse muscle atrophy, and megaoesophagus.

  • Single case report
  • Lack of specific genetic testing to confirm the exact mutation

Cite This Study

Bester et al. (2022) conducted a case report in Nemaline myopathy (n=1). Pyridostigmine was evaluated. A six-month-old Pomeranian dog with progressive muscle weakness and megaoesophagus was diagnosed with congenital nemaline myopathy, confirmed by histological and ultrastructural identification of nemaline rod bodies.
