Rib prominences and soft-tissue lumps: mostly normal variants, confirmed as such.
A prominent or asymmetric sternum
The breastbone’s shape and cartilage, clarified.
Suspected fluid around a lung
Pleural fluid, seen and measured directly.
A swelling after a knock
Haematomas and healing injuries, characterised.
Something felt during illness
Questions raised while examining a poorly child, answered.
Follow-up of a known finding
Tracked without accumulating radiation.

What this scan can find
Your paediatric imaging specialist will be able to guide you through the entire process, after their clinical assessment.
Normal variants, most often
Prominent rib cartilage and asymmetries of growth, the common, benign answers.
Soft-tissue lumps
Cysts, lipomas and nodes on the chest wall, characterised.
Pleural fluid
Fluid around the lung, located and measured.
Cartilage and rib findings
The growing skeleton’s quirks, explained.
Blood flow in any lump

0203 904 4441What happens during the scan
Your child’s scan begins with a short conversation with you about the lump or swelling, when it was noticed, whether it has changed, and any recent chest infection or injury. A parent stays with your child throughout.
Your child lies or sits comfortably, a little warm gel is applied, and a small probe rests gently over the area of concern. Breathing normally is all that is needed. It is painless and radiation-free.
The specialist looks at the lump and the structures under it, the ribs, cartilage, muscle and fat, and checks for fluid around the lungs where that is the question, explaining each finding as it appears.

Most often for a lump or bump on the chest wall or ribs, a swelling after a knock, a lump near the breastbone, or to check for fluid around the lungs after a chest infection. Ultrasound shows soft tissue and fluid clearly without radiation.
Most chest lumps in children are harmless. Common causes include:
The most common finding is a normal but prominent rib or cartilage, which needs no treatment. Others include benign fatty lumps, cysts and lymph nodes. Fluid around the lungs after a chest infection can also be seen and measured. Your specialist explains what was found and whether anything needs follow-up.
Ultrasound is excellent for the chest wall, lumps, ribs and cartilage, and for fluid around the lungs. It cannot see inside healthy lungs, because air blocks sound waves, so it does not replace a chest X-ray for pneumonia or breathing problems.
A chest X-ray is the right test for a cough, breathing difficulty, suspected pneumonia or a suspected broken rib. CT is rarely needed in children. If your child is breathless, struggling to breathe, has blue lips or a high fever with chest pain, go to A&E straight away.
Yes. Ultrasound is very good at showing fluid between the lung and the chest wall, called a pleural effusion, which can follow a chest infection. It shows how much fluid there is and whether it is simple or more complex, which helps doctors decide whether it needs draining.
A small, hard lump at the bottom of the breastbone is usually the xiphoid process, the normal tip of the breastbone, which can stick out more in slim children or after a growth spurt. A firm bump at the side of the breastbone is often a prominent rib cartilage. Both are normal, and ultrasound confirms it.
Rarely. Most rib lumps are a normal variation in how the ribs and cartilage have grown, and are often noticed when a child is slim or after a growth spurt. A lump that is growing quickly, painful at night or comes with fever or weight loss should be checked promptly.
No. The probe rests gently on the skin with a little gel, which can feel cold at first. Most children are calm, and many enjoy watching the screen. You stay with your child throughout and we go at their pace.
Yes. Ultrasound uses sound waves, not radiation, and needs no needles or sedation. It is the recommended first test for many childhood lumps and joint problems precisely because it is so gentle, and it can be repeated safely whenever follow-up is needed.
The scan itself usually takes ten to twenty minutes. Allow around half an hour for the appointment, so there is time to settle your child and talk through the results.
No special preparation is needed: your child can eat and drink as normal. Explain simply that the scan uses a little cold jelly and a camera that does not hurt, dress them in clothes that are easy to lift or roll up, and bring a favourite toy or tablet if it helps.
You will know the findings before you leave, because the specialist explains them during the appointment. The written report is usually on your secure patient portal the same day, ready to share with your GP or paediatrician.
At Harley Street Ultrasound a private child chest ultrasound costs £350, all fees inclusive: the scan, the specialist’s time and your written report. Same-day or next-day appointments are usually available, with the results explained before you leave.
Your specialist tells you in the room, in plain English, and explains exactly what it means. You will never be sent home to wait for a letter. Most findings are benign and need nothing more than a sensible review date.
Anything that does need attention gets a clear, objective recommendation in your report: monitor, test further, or refer. Follow-up tests can usually be arranged at 99 Harley Street, often the same week, and those results are also explained to you personally.
No. Harley Street Ultrasound is a private clinic, so you can book a child chest ultrasound in London directly online or by phone. No GP letter, no waiting list, and same-day or next-day appointments are usually available. If you are searching for a child chest ultrasound near me from anywhere in central London, we are at 99 Harley Street, a short walk from Regent’s Park and Oxford Circus stations.
If you are wondering how much a private child chest ultrasound costs, the answer is published before you book: £350, all fees inclusive: the examination, the specialist’s time, your written report and your images. Insured patients should bring a referral or authorisation number if their policy requires one.
Usually the same day: a Harley Street child chest ultrasound comes with same-day results as standard, and you will already know the findings, because they are explained to you on screen during the appointment.
The written report is prepared by the specialist team and published to your secure patient portal together with your images, with measurements and a clear recommendation, ready to share with your GP or specialist.
Nothing special: there is no aftercare. Your child can feed, eat, play and go back to nursery or school straight away. Ultrasound uses sound waves, not radiation, so it can be repeated safely whenever follow-up is needed. If the results suggest a next step, your specialist explains it to you before you leave.
Yes: completely. Coming to us privately never affects your NHS care. Our job is to get you answers quickly; if anything needs urgent attention, your specialist writes to your NHS GP recommending an urgent appointment, so you re-enter the NHS pathway with a diagnosis already in hand rather than joining the queue from the start.
