General Information About Osteoid Osteoma Tumor
Disease Details and Frequently Asked Questions
It is a benign bone tumor, usually smaller than 1.5 centimeters in size, surrounded by a thickened layer of bone (sclerosis), and produces excessive amounts of prostaglandins (pain-inducing substances).
No. It is absolutely not malignant, does not spread to other organs, and poses no life-threatening risk. It is simply a source of persistent pain in its specific location.
The prostaglandin substances produced by the tumor accumulate more in the area during nighttime rest, causing severe, boring bone pain that can awaken the patient from sleep.
The pain produced by this tumor is dramatically and miraculously relieved entirely within 20-30 minutes when Aspirin or similar simple painkillers (NSAIDs) are taken. This feature is highly typical for its diagnosis.
An X-ray reveals a small, circular lesion with a dark center and a white surrounding halo (nidus) inside the bone. Computed Tomography (CT) and MRI are performed to determine its exact location and size.
Today, without the need for open surgery (carving the bone), a fine needle is inserted directly into the center of the tumor through the skin under CT guidance. Using a radiofrequency device, 90-degree heat is applied, burning the tumor within 5 minutes, and the patient can walk home the very same day.
