pseudohypertrophic dystrophy
A young boy with pseudohypertrophic dystrophy uses a walker to move across a room.
Noun: A specific, inherited form of muscular dystrophy characterized by the enlargement (pseudohypertrophy) of certain muscles, particularly the calves, which is deceptive as the muscle tissue is actually weakened and replaced by fat and connective tissue. It is the most common form of muscular dystrophy, with an X-linked recessive pattern of inheritance.
This is a medical term used in clinical, scientific, and patient-advocacy contexts. - It is used to diagnose and classify a specific neuromuscular disorder. - It is used in discussions of genetics, inheritance patterns, and patient care.
- The diagnosis of pseudohypertrophic dystrophy was confirmed through genetic testing.
- Research into treatments for pseudohypertrophic dystrophy has advanced significantly in recent years.
- Families with a history of pseudohypertrophic dystrophy often seek genetic counseling.
- Clinical Context: The term is often used interchangeably with Duchenne muscular dystrophy (DMD), which is its more precise clinical name. "Pseudohypertrophic dystrophy" specifically references the physical symptom of enlarged but weak muscles.
- Historical Context: The term describes the observable clinical sign (pseudohypertrophy) that helps distinguish this form of dystrophy from others.
- Duchenne muscular dystrophy (DMD): The primary and more specific medical term for this condition.
- Muscular dystrophy: The broader category of genetic diseases characterized by progressive weakness and loss of muscle mass.
- Pseudohypertrophy: The condition of a muscle appearing enlarged due to infiltration of fat and fibrous tissue rather than genuine muscle growth.
- Duchenne muscular dystrophy (DMD)
- Duchenne's dystrophy
This term has one primary, specific medical meaning. It is not used in idiomatic or figurative language. The "pseudohypertrophic" component is key, indicating the deceptive enlargement of muscles that are functionally deficient.

- the most common form of muscular dystrophy; inheritance is X-linked recessive (carried by females but affecting only males)
