Sacral Tumours on MRI: A Pictorial Essay

Area of Science:

• Oncology
• Radiology
• Medical Imaging

Background:

• Sacral tumors encompass both primary bone neoplasms and secondary metastatic lesions.
• Bone metastases are the most common cause of sacral tumors due to the sacrum's rich hematopoietic bone marrow.
• Primary bone tumors of the sacrum must be considered, especially in solitary lesions without a prior cancer history.

Observation:

• Clinical presentation of sacral tumors is often non-specific, necessitating advanced imaging techniques.
• Magnetic resonance imaging (MRI) is essential for accurate diagnosis and treatment planning.
• This essay focuses on the characteristic appearances of common sacral tumors on MRI.

Findings:

• Metastatic disease is the predominant etiology of sacral tumors.
• Primary tumors arise from various sacral components.
• MRI reveals distinct features aiding in the differential diagnosis of sacral lesions.

Implications:

• Accurate diagnosis of sacral tumors via MRI influences therapeutic strategies.
• Understanding the imaging characteristics of primary versus secondary sacral tumors is clinically significant.
• This pictorial essay serves as a visual guide for radiologists and oncologists.
