​Osteoid Osteoma

Osteoid osteoma is a small benign (noncancerous) tumour that arises from the osteoblast (bone building cells). It is found in the long bones of legs, usually in the thighbones but it can also occur in the bones of the hands and lower part of the spine. These tumours are less than a centimetre and half in size.

The reason for their cause is unknown.

Osteoid Osteoma can be painful but it does not spread. It can occur at any age but mostly affects children and young adults. In young children, it can cause the bone deformity or overgrowth of bone. Boys are more likely to suffer from Osteoid Osteoma than girls.​​

Symptoms of Osteoid Osteoma can be different for each child, they include:

  • Dull or sharp pain that intensifies at night. This pain is not related to activity.

  • Pain which is alleviated by aspirin or other anti-inflammatory drugs​

If you notice any of the above mentioned symptoms in your child, you should take them to a doctor at Musculoskeletal and Sports Medicine Service Line at The Aga Khan University Hospital.​
Your time with your doctor maybe limited, so make sure to prepare for your visit beforehand. Here are some tips to help get you started​

Effective treatment depends on accurate diagnosis. Your doctor will take your child through a series of tests to determine the exact type of tumour and whether it has spread. These include:

  • Physical exam involving tests of reflexes, muscle strength, coordination, alertness, eye and mouth movements etc.

  • X-rays in which a small amount of radiation is used to generate an image of the bones and organs, to detect the presence of a tumour

  • Computerized Tomography (CT) scans, in which a series of detailed images of the body are taken by a computer  

  • Magnetic Resonance Imaging (MRI) scans, in which a series of detailed images of the body are made on the computer using a magnet and radio waves. This is done to produce better images of soft tissue

  • Biopsy, in which a tissue sample of the tumour is extracted to be studied under the microscope​

The treatment options that may be offered to you or your child will include:

  • Anti-inflammatory drugs to help in pain relief.

  • Percutaneous radiofrequency ablation, in which a needle is inserted beneath the skin and radiofrequencies are passed through it to kill the tumour cells by heating them to a high temperature. This is a minimally invasive procedure

  • Curettage, in which the tumour is scrapped out of the bone. Recurrence of tumour after this procedure is rare.

While cure is possible with successful treatment, tumours can recur. Therefore you should be constantly vigilant with regular follow-ups of your child. ​
