Acro-osteolysis: imaging, differential diagnosis, and disposition review

Area of Science:

• Radiology
• Orthopedics
• Pathology

Background:

• Acro-osteolysis involves osseous destruction of distal phalanges in hands or feet.
• It presents in terminal tuft, midshaft, or mixed patterns.
• Radiographic identification is typically straightforward.

Purpose of the Study:

• To highlight the diagnostic challenges beyond initial radiographic recognition of acro-osteolysis.
• To emphasize the crucial role of radiologists in differential diagnosis.
• To underscore the importance of advanced imaging and tissue diagnosis recommendations.

Main Methods:

• Review of radiographic findings in acro-osteolysis.
• Analysis of differential diagnostic considerations.
• Evaluation of advanced imaging and invasive diagnostic techniques.

Main Results:

• While acro-osteolysis is readily identifiable on radiographs, establishing an accurate differential diagnosis is complex.
• Appropriate recommendations for advanced imaging or tissue biopsy are often challenging.
• Radiologists' advanced assessments are key to diagnosis.

Conclusions:

• Radiologists play a vital role in differentiating the causes of acro-osteolysis.
• Expert radiological assessment facilitates timely diagnosis and management.
• Advanced imaging and tissue diagnosis are critical for definitive management.
