Things worth knowing about "Lymphadenitis Colli"
Lymphadenitis colli is an inflammation of the cervical lymph nodes, most commonly caused by infections. It presents with swelling and pain in the neck area.
What is Lymphadenitis Colli?
Lymphadenitis colli refers to the inflammation of the lymph nodes in the neck region. Lymph nodes are small, bean-shaped organs of the immune system distributed along the lymphatic vessels. They play a key role in filtering pathogens and activating immune responses. When these nodes become inflamed, they swell and may become tender or painful. The condition is common across all age groups, particularly in children.
Causes
The most frequent cause of lymphadenitis colli is an infection in the head and neck region. Both bacterial and viral origins are distinguished:
- Bacterial causes: Streptococci, Staphylococci, Mycobacterium tuberculosis (in the tuberculous form)
- Viral causes: Epstein-Barr virus (infectious mononucleosis), Adenoviruses, Cytomegalovirus
- Other causes: Dental infections, tonsillitis, otitis media, and in rarer cases, malignant tumors or autoimmune conditions
Symptoms
The symptoms of lymphadenitis colli can vary depending on the underlying cause and severity. Common signs include:
- Visibly swollen and palpable lymph nodes in the neck
- Tenderness or spontaneous pain over the affected lymph nodes
- Redness and warmth of the overlying skin (particularly in bacterial cases)
- General malaise, fatigue, and weakness
- Fever, especially with bacterial infections
- In severe cases: formation of an abscess (a collection of pus within the lymph node)
Diagnosis
Diagnosis is usually established through a physical examination, during which the physician palpates the lymph nodes and evaluates their size, consistency, and tenderness. Further diagnostic steps may include:
- Blood tests: Measurement of inflammatory markers (CRP, ESR) and a complete blood count
- Ultrasound (sonography): Imaging to assess the size and internal structure of the lymph nodes
- Throat or wound swabs: To identify the responsible bacteria or viruses
- Biopsy: Tissue sampling for histopathological analysis when the cause remains unclear or swelling persists, to rule out malignancy
- Imaging (CT/MRI): In cases of suspected deep-space infections or complications
Treatment
Treatment depends on the underlying cause of the inflammation:
Bacterial Lymphadenitis Colli
Bacterial infections are treated with antibiotics, commonly penicillin or amoxicillin. If an abscess has formed, surgical incision and drainage may be required. Treating the primary source of infection — such as tonsillitis or a dental abscess — is equally important.
Viral Lymphadenitis Colli
Viral forms typically resolve on their own. Treatment is symptomatic and includes pain-relieving and fever-reducing medications such as paracetamol or ibuprofen. Adequate rest and hydration support recovery.
Tuberculous Lymphadenitis Colli
When mycobacteria are involved, a specific combination regimen of antitubercular drugs over several months is required, following established tuberculosis treatment guidelines.
When to See a Doctor
Medical attention should be sought promptly if neck lymph node swelling persists for more than two weeks, is accompanied by fever, unexplained weight loss, or night sweats. These symptoms may indicate a more serious underlying condition that requires further investigation.
