ICD-10: M60.02

Infective myositis, specifically coded as ICD-10-CM M60.02, refers to an inflammatory condition of the muscle tissue in the upper arm caused by an infectious agent. This condition can arise from various pathogens, including bacteria, viruses, or parasites, leading to muscle inflammation and associated symptoms.

Clinical Description

Definition

Infective myositis is characterized by the inflammation of muscle tissue due to an infectious process. The upper arm, which includes the biceps and triceps muscles, is one of the common sites affected. The condition can result from direct infection of the muscle or secondary to systemic infections that manifest in the muscle tissue.

Etiology

The causes of infective myositis can vary widely:
- Bacterial Infections: Commonly caused by organisms such as Staphylococcus aureus or Streptococcus species, which can enter the muscle through breaks in the skin or via hematogenous spread.
- Viral Infections: Viruses like influenza or enteroviruses can also lead to myositis, often as part of a broader systemic illness.
- Parasitic Infections: Certain parasites, such as Trichinella spiralis, can cause myositis, particularly in endemic areas.

Symptoms

Patients with infective myositis may present with:
- Localized Pain: Pain in the upper arm, which may be severe and exacerbated by movement.
- Swelling and Tenderness: The affected area may appear swollen and tender to touch.
- Muscle Weakness: Patients often experience weakness in the affected arm, impacting daily activities.
- Systemic Symptoms: Fever, malaise, and fatigue may accompany the localized symptoms, indicating a systemic infection.

Diagnosis

Diagnosis typically involves:
- Clinical Evaluation: A thorough history and physical examination to assess symptoms and identify potential sources of infection.
- Laboratory Tests: Blood tests may reveal elevated inflammatory markers (e.g., C-reactive protein, erythrocyte sedimentation rate) and signs of infection (e.g., leukocytosis).
- Imaging Studies: MRI or ultrasound may be used to visualize muscle inflammation and rule out abscess formation.
- Muscle Biopsy: In some cases, a biopsy may be necessary to confirm the diagnosis and identify the causative organism.

Treatment

Management of infective myositis involves:
- Antibiotic Therapy: If a bacterial infection is confirmed or suspected, appropriate antibiotics are initiated.
