[Intraosseus lipoma (author's transl)]

Area of Science:

• Oncology
• Radiology
• Pathology

Background:

• Intraosseous lipomas are rare benign bone tumors.
• Rib involvement is exceptionally uncommon.
• Accurate diagnosis can be challenging due to nonspecific presentation.

Observation:

• A case of intraosseous lipoma of the rib is presented.
• The tumor presented with bone expansion and an endothoracic mass.
• Arteriographic findings were emphasized, suggesting an "angiolipoma".

Findings:

• The case highlights the diagnostic utility of arteriography in identifying intraosseous lipomas.
• This represents one of the few documented cases in the medical literature.
• Undiagnosed or unclassified cases may contribute to underestimation of prevalence.

Implications:

• Increased awareness of this rare entity is crucial for timely diagnosis.
• Arteriography can be a valuable tool for characterizing these vascularized bone tumors.
• Histological classification is essential for definitive diagnosis and management of intraosseous lipomas.
