pleurisy CT scan preparation
Informed by recognized medical guidance
Overview
Pleurisy is inflammation of the pleura, the thin membranes that line the lungs and chest cavity. This causes sharp chest pain, especially when you breathe in, cough, or sneeze. A CT scan is an imaging test that helps doctors see the pleura and surrounding structures to find the cause of the inflammation.
Key facts
- Pleurisy often follows a viral infection, like the flu or a cold.
- A CT scan provides detailed pictures of the pleura and lungs.
- Treatment focuses on the underlying cause, such as an infection or autoimmune condition.
Pleurisy is not very common, but it can happen as a complication of respiratory infections or other health problems.
It can affect people of all ages, but it is more common in those with lung infections, autoimmune diseases (like lupus or rheumatoid arthritis), chest injuries, or blood clots in the lungs.
Symptoms
- Sudden, severe chest pain that does not go away
- Trouble breathing or feeling like you cannot get enough air
- Coughing up blood
- Pain that spreads to your arm, neck, or jaw
- ⚠High fever (over 38°C or 100.4°F) with chest pain
- ⚠Worsening shortness of breath
- ⚠Persistent pain despite rest
Common symptoms
- Sharp chest pain that gets worse when you breathe in, cough, or sneeze
- Shortness of breath
- Dry cough
- Fever and chills
Symptoms in children
- Irritability and fussiness
- Refusing to feed or eat
- Rapid breathing or grunting
Symptoms in older adults
- Milder chest pain that may not be as sharp
- Confusion or tiredness
- Loss of appetite
Causes
Main causes
- Viral infections (like flu, COVID-19, or common cold)
- Bacterial infections (like pneumonia)
- Autoimmune diseases (such as lupus or rheumatoid arthritis)
- Chest injury or trauma
- Pulmonary embolism (blood clot in the lungs)
Risk factors
- Recent respiratory infection
- Smoking
- Autoimmune conditions
- Chest surgery or injury
- Taking certain medications that can cause pleuritis
When to see a doctor
See a doctor urgently if:
- Sudden severe chest pain that makes it hard to breathe
- Chest pain with fever and shortness of breath
- Coughing up blood
Book a routine appointment if:
- You have chest pain when breathing that lasts more than a few days
Diagnosis
Your doctor will ask about your symptoms and medical history, listen to your chest with a stethoscope, and may order imaging tests like a chest X-ray or CT scan. Blood tests can also help find signs of infection or inflammation.
Tests that may be done
- Chest X-ray
- CT scan (computed tomography) of the chest
- Blood tests (to check for infection or autoimmune markers)
- Ultrasound of the chest (sometimes used)
What to expect at your appointment
If you are having a CT scan for pleurisy, the test is painless and takes about 10 to 30 minutes. You will lie on a table that slides into a large doughnut-shaped scanner. You may be asked to hold your breath for a few seconds. If contrast dye is used (to make images clearer), you may need to avoid eating for a few hours beforehand. Let your doctor know if you have allergies, asthma, kidney problems, or if you are pregnant.
Treatment
Treatment for pleurisy aims to relieve pain and address the underlying cause. Most people recover with rest and treatment of the infection or condition that triggered it.
Self-care at home
- Rest until the pain improves
- Apply a warm compress to your chest for comfort
- Take over-the-counter pain relievers as recommended by your doctor
Medical treatments
Your doctor may prescribe anti-inflammatory medications to reduce swelling and pain. If a bacterial infection is the cause, you will likely need antibiotics. For pleurisy related to autoimmune conditions, medications that calm the immune system may be used. Always take medicines exactly as your doctor advises.
When is surgery considered?
Surgery is rarely needed. In some cases, if fluid or pus builds up around the lungs (pleural effusion or empyema), a doctor may drain it using a needle or a small tube.
Living with this condition
During recovery, take it easy. Use pillows to support your chest when you cough. Avoid heavy lifting or strenuous activities until your doctor says it is safe.
Lifestyle tips
- Quit smoking – smoking can make pleurisy worse and increase your risk of complications.
- Manage stress with relaxation techniques like deep breathing.
Diet and exercise
Eat a balanced diet with fruits, vegetables, and whole grains to support your immune system. Gentle walking is okay once pain lessens, but avoid exercise that makes you short of breath.
Mental health and emotional wellbeing
Chronic chest pain can be scary and stressful. It is normal to feel anxious or down. Talk to your doctor if you are feeling overwhelmed – they can offer support or refer you to a counselor.
Prevention
Not all cases can be prevented, but you can lower your risk by protecting yourself against infections and managing health conditions.
Vaccines
Flu and pneumonia vaccines can help prevent infections that sometimes lead to pleurisy. Ask your doctor if you are up to date.
Screening programmes
There is no routine screening for pleurisy.
Complications
If left untreated
- Pleural effusion – fluid buildup around the lungs that makes breathing harder
- Empyema – infected fluid that may require drainage
- Scarring of the pleura (pleural thickening)
- Breathing difficulties
Long-term outlook
With proper diagnosis and treatment, most people with pleurisy recover fully within a few weeks to months. The key is to treat the underlying cause early. While pleurisy can be painful, it rarely causes lasting damage when managed well.
