A retropharyngeal abscess is a collection of pus in the back of the throat. A retropharyngeal abscess is caused by a bacterial infection. Symptoms include difficulty and pain when swallowing, a fever, stiff neck, and noisy breathing.
Can TB cause abscess?
Metastatic tuberculosis abscess is a rare form of skin tuberculosis. It is characterized by nodule and abscess formation throughout the body after hematogenous spread of mycobacterium tuberculosis from a primary focus during a period of impaired immunity.
What causes tuberculous cold abscess?
Cold abscess refers to an abscess that lacks the intense inflammation usually associated with infection. This may be associated with infections due to bacteria like tuberculosis and fungi like blastomycosis that do not tend to stimulate acute inflammation.
What is a tuberculous abscess?
Tuberculous abscesses are an uncommon presentation of tuberculosis, most often encountered in immunocompromised individuals (e.g. HIV/AIDS). Unlike the far more common tuberculomas (tuberculous granulomas), tuberculous abscesses contain pus with abundant identifiable organisms 1.
What is an abscess caused by?
Causes of abscesses Most abscesses are caused by a bacterial infection. When bacteria enter your body, your immune system sends infection-fighting white blood cells to the affected area. As the white blood cells attack the bacteria, some nearby tissue dies, creating a hole which then fills with pus to form an abscess.
What causes parapharyngeal abscess?
Usually, parapharyngeal abscesses arise secondary to oropharyngeal infections that spread either by direct continuity or by lymphatic drainage: acute and chronic tonsillitis. bursting of peritonsillar abscess. dental infection usually comes from the lower last molar tooth.
How is tuberculous abscess diagnosed?
Isolating M. tuberculosis in culture is the only way to make a definitive diagnosis. Tuberculous gumma is a multibacillary form of CTB that can occur without any underlying source of tuberculosis. Histology of CTB lesions reveals massive necrosis and abscess formation.
What is BCG injection?
The BCG vaccine protects against tuberculosis, which is also known as TB. TB is a serious infection that affects the lungs and sometimes other parts of the body, such as the brain (meningitis), bones, joints and kidneys.
Is a cold abscess a TB?

What is tuberculous granuloma?
Tuberculosis is the formation of an organized structure called granuloma. It consists mainly in the recruitment at the infectious stage of macrophages, highly differentiated cells such as multinucleated giant cells, epithelioid cells and Foamy cells, all these cells being surrounded by a rim of lymphocytes.
How is tuberculous abscess treated?
TUBERCULOUS ABSCESS SUCCESSFULLY TREATED BY ASPIRATION AND INJECTION OF STREPTOMYCIN. AMOS R. KOONTZ, M.D. A tuberculous abscess arising from a tuberculous costal cartilage was successfully treated by aspiration of the contents of the abscess cavity and immediate injection of streptomycin into the cavity.
What are the types of tuberculosis?
Tuberculosis: Types
- Active TB Disease. Active TB is an illness in which the TB bacteria are rapidly multiplying and invading different organs of the body.
- Miliary TB. Miliary TB is a rare form of active disease that occurs when TB bacteria find their way into the bloodstream.
- Latent TB Infection.
What is the epidemiology of retropharyngeal abscess?
Epidemiology. Retropharyngeal abscesses are most frequently encountered in children, with 75% of cases occurring before the age of 5 years, and often in the first year of life 1-3. This is likely due to the combination of prominent retropharyngeal nodal tissue and frequency of middle ear and nasopharyngeal infections.
Is tuberculosis retropharyngeal abscess a curable disease?
Despite of availability of effective anti-tuberculosis drugs, tuberculosis remains leading cause of death among curable infectious diseases. Tuberculosis retropharyngeal abscess is a rare presentation of extra pulmonary tuberculosis and a potentially life-threatening deep neck infection.
What are the most common sites of extrapulmonary tuberculosis (TB)?
Lymph nodes, pleura, genitourinary tract, bones and joints, the meninges, peritoneum and pericardium are the common sites of extrapulmonary tuberculosis in descending order of frequency. A case with retropharyngeal tuberculosis abscess with recurrence despite surgical drainage and intense medical treatment is reported.
What are the possible complications of retropharyngeal effusion?
Serious complications in developed nations with prompt access to imaging and antibiotic are uncommon, however, complacency needs to be avoided as retropharyngeal can lead to potentially life-threatening complications including 1-3: posterior extension to pre-vertebral space, diskitis osteomyelitis, epidural abscess.
