ICD-10: M60.002

Infective myositis, classified under ICD-10 code M60.002, refers to inflammation of the muscle tissue due to infectious agents. The diagnosis of this condition typically involves a combination of clinical evaluation, laboratory tests, and imaging studies. Below are the key criteria used for diagnosing infective myositis:

Clinical Presentation

1. Symptoms: Patients often present with muscle pain (myalgia), weakness, and swelling in the affected area. The onset of symptoms may be acute or subacute, depending on the causative agent.
2. History: A thorough medical history is essential, including any recent infections, travel history, exposure to infectious agents, or underlying health conditions that may predispose the patient to infections.

Laboratory Tests

1. Blood Tests:
   - Creatine Kinase (CK) Levels: Elevated CK levels can indicate muscle damage and inflammation.
   - Complete Blood Count (CBC): This may show leukocytosis (increased white blood cells) if an infection is present.
   - Serological Tests: Specific tests may be conducted to identify infectious agents, such as viral or bacterial serologies.

2. Muscle Biopsy: In some cases, a biopsy of the affected muscle may be performed to confirm the diagnosis. Histological examination can reveal inflammatory infiltrates and necrosis, which are indicative of myositis.

Imaging Studies

1. Magnetic Resonance Imaging (MRI): MRI can be useful in visualizing muscle inflammation and edema. It helps differentiate myositis from other conditions that may cause muscle pain or weakness.
2. Ultrasound: This imaging modality can also assess muscle structure and detect areas of inflammation.

Differential Diagnosis

It is crucial to rule out other conditions that may mimic infective myositis, such as:
- Autoimmune myositis
- Muscular dystrophies
- Neuromuscular disorders
