Final Answer:
The symptoms, including progressive limb weakness, swallowing difficulties, specific muscle weakness, normal deep tendon reflexes, and elevated creatine kinase, suggest a possible diagnosis of inclusion body myositis (IBM), a rare inflammatory muscle disease.
Step-by-step explanation:
The symptoms described, including progressive limb weakness, swallowing difficulties, specific muscle weakness (neck extensors, quadriceps, feet dorsal flexors, extensor pollicis longus, wrist/finger flexors), normal deep tendon reflexes (DTRs), and elevated creatine kinase (CK), raise suspicion of inclusion body myositis (IBM).
IBM is a rare inflammatory muscle disease that typically affects individuals over the age of 50. It is characterized by asymmetric weakness and atrophy, and despite normal DTRs, it can lead to significant disability.
Definitive diagnosis often requires muscle biopsy. A thorough evaluation by a healthcare professional is essential for accurate diagnosis and appropriate management. Definitive diagnosis may require a muscle biopsy, and consultation with a healthcare professional is crucial for accurate assessment and management.
Your question seems to be incomplete ,it should be
3 month progressive limb weakness L>R, problems swallowing. Normal CN, weakness in neck extensor muscles, in distal and proximal muscles (quadriceps, feet dorsal flexors, extensor pollicis longus) and in wrist/finger flexors. DTRs normal. Motor tone/coordination/gait normal. Elevated CK. All of these faetures belongs to which disease ,or what is your composite diagnosis?
