Summary

Radiologic imaging of spinal chordoma in older adults with chronic back pain reveals characteristic osteosclerosis or osteolytic lesions. A paraspinal soft-tissue mass often accompanies these vertebral body tumors, aiding diagnosis.

Area of Science:

Radiology

Background:

Chordoma is a rare bone tumor originating from notochordal remnants.
Spinal chordomas can present with vague, long-standing symptoms like back pain, particularly in older individuals.

Purpose of the Study:

To describe the radiologic features of spinal chordomas.
To correlate imaging findings with clinical presentation in patients with spinal chordoma.

Main Methods:

Retrospective review of 14 spinal chordoma cases (cervical, thoracic, lumbar).
Analysis of conventional radiographs and CT scans.
Correlation of imaging findings with patient age and symptoms.

Main Results:

Most tumors (13/14) originated in the vertebral body.
Osteosclerosis was present in 64% of cases; osteolytic lesions in 36%.
A soft-tissue mass was identified in 9 patients; disk involvement in 3.

Conclusions:

Spinal chordomas often present as sclerotic or osteolytic vertebral lesions.
The presence of a paraspinal soft-tissue mass in older patients with chronic back pain suggests chordoma.
Radiographic features, combined with clinical history, are crucial for suspecting spinal chordoma.
