Intracortical intraosseous lipoma.

Area of Science:

• Orthopedic Oncology
• Musculoskeletal Radiology
• Bone Pathology

Background:

• Intraosseous lipomas are rare, benign primary bone neoplasms with a reported incidence of less than 1%.
• These lesions predominantly occur within the intramedullary canal of long bones.
• Accurate differentiation from other bone pathologies is crucial for appropriate management.

Observation:

• This case report details an uncommon intraosseous lipoma situated within the cortical bone.
• The lesion's specific location presented diagnostic challenges.
• High-resolution imaging was essential for characterizing the lesion.

Findings:

• The study focuses on the characteristic findings of an intracortical intraosseous lipoma on 3 Tesla (3T) Magnetic Resonance Imaging (MRI).
• Specific signal intensities and topographical features on 3T MRI were observed.
• These MRI findings are presented to assist in distinguishing this entity from mimics.

Implications:

• Understanding the imaging features of intracortical intraosseous lipomas on 3T MRI improves diagnostic accuracy.
• This knowledge aids in differentiating these benign tumors from potentially malignant lesions or other bone abnormalities.
• Accurate diagnosis prevents unnecessary invasive procedures and guides appropriate clinical or surgical management.
