Overview
Macrophagic myofasciitis is a condition characterized by muscle inflammation and infiltration of macrophages in the muscle fascia, often associated with intramuscular aluminum deposition, typically following vaccination or other intramuscular injections 123.Diagnosis
Presence of muscle tenderness and weakness
Elevated creatine kinase levels 12
Histopathological evidence of macrophage infiltration and aluminum deposits on muscle biopsy 12
Exclusion of other myopathies through clinical evaluation and laboratory tests 12Management
Symptomatic treatment with nonsteroidal anti-inflammatory drugs (NSAIDs) for pain and inflammation 12
Physical therapy to maintain muscle function and mobility 12
Monitoring for and managing potential complications such as chronic pain 12
No specific antidotal treatment for aluminum deposition is widely recommended 12Special Populations
Limited evidence regarding specific management in pregnancy, pediatrics, or elderly populations 123
Comorbidities may influence treatment approach but specific guidelines are not provided 12Key Recommendations
Perform muscle biopsy for definitive diagnosis, including histopathological examination for macrophage infiltration and aluminum deposits (Evidence: Moderate 12)
Initiate symptomatic treatment with NSAIDs for managing pain and inflammation (Evidence: Moderate 12)
Implement physical therapy to support muscle function and prevent atrophy (Evidence: Expert opinion 12)References
