Lung needle biopsy
Transthoracic needle aspiration; Percutaneous needle aspiration
A lung needle biopsy is a method to remove a piece of lung tissue for examination. If it is done through the wall of your chest, it is called a transthoracic lung biopsy.
How the Test is Performed
The procedure usually takes 30 to 60 minutes. The biopsy is done in the following way:
-
A
chest x-ray
or
chest CT scan
may be used to find the exact spot for the biopsy. If the biopsy is done using a CT scan, you may be lying down during the exam.
Chest x-ray
A chest x-ray is an x-ray of the chest, lungs, heart, large arteries, ribs, and diaphragm.
Chest CT scan
A chest CT (computed tomography) scan is an imaging method that uses x-rays to create cross-sectional pictures of the chest and upper abdomen....
- You may be given a sedative to relax you.
- You sit with your arms resting forward on a table. Your skin where the biopsy needle is inserted is scrubbed.
- A local painkilling medicine (anesthetic) is injected.
- The doctor makes a small cut in your skin.
-
The biopsy needle is inserted into the abnormal tissue,
tumor
, or lung tissue. A small piece of tissue is removed with the needle.
Tumor
A tumor is an abnormal growth of body tissue. Tumors can be cancerous (malignant) or noncancerous (benign).
- The needle is removed. Pressure is placed on the site. Once bleeding has stopped, a bandage is applied.
- A chest x-ray is taken right after the biopsy.
- The biopsy sample is sent to the lab. Analysis usually takes a few days.
How to Prepare for the Test
You should not eat for 6 to 12 hours before the test. Follow instructions about not taking aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, or blood thinners such as warfarin for a period of time before the procedure. Check with your health care provider before changing or stopping any medicines.
Before a needle biopsy of the lung, a chest x-ray or chest CT scan may be performed.
How the Test will Feel
You will receive an injection of anesthetic before the biopsy. This injection will sting for a moment. You will feel pressure and a brief, sharp pain when the biopsy needle touches the lung.
Why the Test is Performed
A lung needle biopsy is done when there is an abnormal condition near the surface of the lung, in the lung itself, or on the chest wall. Most often, it is done to rule out cancer. The biopsy is usually done after abnormalities appear on a chest x-ray or CT scan.
Normal Results
In a normal test, the tissues are normal and there is no cancer or growth of bacteria, viruses, or fungi if a culture is performed.
What Abnormal Results Mean
An abnormal result may be due to any of the following:
- Bacterial, viral, or fungal lung infection
-
Cancerous cells (
lung cancer
, mesothelioma)
Lung cancer
Small cell lung cancer (SCLC) is a fast-growing type of lung cancer. It spreads much more quickly than non-small cell lung cancer. There are two typ...

Risks
Sometimes, a collapsed lung ( pneumothorax ) occurs after this test. A chest x-ray will be done to check for this. The risk is higher if you have certain lung diseases such as emphysema. Usually, a collapsed lung after a biopsy does not need treatment. But if the pneumothorax is large or does not improve, a chest tube is inserted to expand your lung.
Pneumothorax
A collapsed lung occurs when air escapes from the lung. The air then fills the space outside of the lung, between the lung and chest wall. This bui...
In rare cases, pneumothorax can be life threatening if air escapes from the lung, gets trapped in the chest, and presses on the rest of your lungs or heart.
Whenever a biopsy is done, there is a risk of too much bleeding (hemorrhage). Some bleeding is common, and a provider will monitor the amount of bleeding. In rare cases, major and life-threatening bleeding can occur.
A needle biopsy should not be performed if other tests show that you have:
- Bleeding disorder of any type
- Bullae (enlarged alveoli that occur with emphysema)
-
Cor pulmonale
(condition that causes the right side of the heart to fail)

Cysts
of the lung
Cysts
A cyst is a closed pocket or pouch of tissue. It can be filled with air, fluid, pus, or other material.
-
High blood pressure in the lung arteries
High blood pressure in the lung arterie
Pulmonary hypertension is high blood pressure in the arteries of the lungs. It makes the right side of the heart work harder than normal.
-
Severe
hypoxia
(low oxygen)
Hypoxia
Cyanosis is a bluish color to the skin or mucous membrane that is usually due to a lack of oxygen in the blood.
Considerations
Signs of a collapsed lung include:
-
Blueness of the skin

Cyanosis is a bluish color to the skin or mucous membrane that is usually due to a lack of oxygen in the blood.
- Chest pain
-
Rapid heart rate
(rapid pulse)
Rapid heart rate
A bounding pulse is a strong throbbing felt over one of the arteries in the body. It is due to a forceful heartbeat.

Shortness of breath

Breathing difficulty may involve:Difficult breathingUncomfortable breathingFeeling like you are not getting enough air
If any of these occur, call your provider right away.

Lung biopsy - illustration
A needle lung biopsy is performed when there is an abnormal condition that is near the surface of the lung, in the tissues surrounding the lungs, or on the chest wall. The test can be performed to obtain a sample for culture when infection of the lung is suspected, and sputum or bronchoalveolar lavage cultures have not identified the cause of the infection.

Lung tissue biopsy - illustration
To obtain a sample of lung tissue for biopsy, a needle is inserted within the lung and a sample is withdrawn and sent to the laboratory. The laboratory test isolates and identifies organisms that cause infection from the lung specimen. A lung needle biopsy culture is performed when infection of the lung is suspected and sputum or bronchoalveolar lavage cultures have not identified the cause of the infection.
