Multiple myeloma: early vertebral involvement assessed by computerised tomography.

Area of Science:

• Radiology
• Oncology
• Medical Imaging

Background:

• Multiple myeloma frequently involves the skeleton, typically evaluated by radiography.
• Radio-isotope bone scans have limited sensitivity for myeloma-related bone changes.
• Conventional radiography may fail to detect early or subtle skeletal involvement.

Purpose of the Study:

• To evaluate the efficacy of computerised tomography (CT) in detecting spinal lesions in multiple myeloma.
• To compare the sensitivity and accuracy of CT versus conventional radiography for assessing vertebral involvement in myeloma.

Main Methods:

• Retrospective analysis of six multiple myeloma patients with no initial radiographic bone lesions.
• CT examination of the vertebral column in these patients to identify lytic lesions.
• CT evaluation in three additional patients with extensive radiographic evidence of myeloma bone disease.

Main Results:

• CT identified lytic lesions in the vertebral spongiosa in four of six patients initially showing no radiographic bone involvement.
• In patients with known extensive disease, CT revealed more widespread vertebral column involvement than conventional radiography.
• CT demonstrated earlier vertebral lesions and provided more accurate delineation of lesion extent.

Conclusions:

• Computerised tomography (CT) is a valuable tool for early detection of spinal lesions in multiple myeloma.
• CT offers superior sensitivity and accuracy in assessing the extent of vertebral involvement compared to conventional radiography.
• CT imaging can significantly enhance the diagnostic evaluation of skeletal myeloma.
