Overview of Sacral Chordomas
Sacral chordomas are rare tumors that come from leftover parts of the notochord. This is a structure that exists during the early stages of development. They usually grow in the sacrum, which is at the base of the spine. About 30-50% of all chordoma cases are sacral chordomas.
Because they grow slowly and are in a hard-to-reach spot, they’re often found late. Finding them early is key, which is why sacral tumor radiology is so important.
What is a Sacral Chordoma?
A sacral chordoma is a bone cancer that starts from leftover notochord parts. These tumors can spread to nearby bones and soft tissues. They have special cells called physaliferous cells that are only found in chordomas.
To figure out how big the tumor is and what’s around it, doctors use imaging a lot.
Symptoms and Clinical Presentation
Symptoms of sacral chordomas can be different for everyone. But, common ones include pain in the area, which might spread to the legs. People might also feel weak or numb because of nerve pressure.
Some might have trouble with their bowel or bladder if the tumor presses on the nerves there. These symptoms can make it hard to diagnose the tumor early.
- Localized sacral pain
- Neurological deficits
- Bowel and bladder dysfunction
- Lower extremity pain or weakness
It’s hard to spot these tumors early because their symptoms are not clear. That’s why sacral tumor radiology is so important. Regular scans and doctor checks help find these tumors early. This makes treatment more effective.
The Importance of Imaging in Sacral Chordomas
Imaging is key in finding and treating sacral chordomas. It shows the size, spread, and how it touches nearby parts. This helps doctors make good treatment plans. We’ll see how imaging helps in making diagnoses.
