Multimodality imaging features of USP6-associated neoplasms.

Area of Science:

• Oncology
• Pathology
• Radiology

Background:

• USP6 gene rearrangements are recognized in a spectrum of mesenchymal neoplasms.
• These USP6-driven tumors, including aneurysmal bone cysts, exhibit overlapping features.
• They can be mistaken for malignant bone and soft tissue lesions due to rapid growth and similar appearance.

Purpose of the Study:

• To review the imaging characteristics of USP6-driven neoplasms.
• To highlight features differentiating these lesions from malignant counterparts.
• To discuss the role of imaging and molecular analysis in diagnosis.

Main Methods:

• Review of imaging findings for various USP6-driven neoplasms.
• Comparison of imaging features with known malignant bone and soft tissue tumors.
• Discussion of diagnostic criteria integrating imaging and molecular data.

Main Results:

• USP6-driven neoplasms present with diverse but often overlapping imaging features.
• Key imaging findings can help differentiate these benign/locally aggressive lesions from true malignancies.
• Molecular analysis, particularly USP6 rearrangement detection, is crucial for definitive diagnosis.

Conclusions:

• Accurate imaging interpretation is vital for suspecting USP6-driven neoplasms.
• Distinguishing these from malignant lesions requires careful evaluation of imaging characteristics.
• A combined approach of imaging and molecular testing ensures correct diagnosis and management.
