Angioleiomyoma: How to Suggest the Diagnosis on Imaging?

Area of Science:

• Oncology
• Radiology
• Dermatopathology

Background:

• Angioleiomyomas are rare, benign neoplasms derived from smooth muscle.
• These tumors typically arise in the extremities and are often superficial.

Purpose of the Study:

• To describe the characteristic imaging features of angioleiomyomas on ultrasound (US) and magnetic resonance imaging (MRI).
• To highlight the diagnostic utility of US and MRI in differentiating angioleiomyomas from other superficial lesions.

Main Methods:

• Review of imaging findings (US and MRI) in pathologically confirmed cases of angioleiomyoma.
• Correlation of imaging features with clinical presentation and histopathological results.

Main Results:

• Angioleiomyomas typically present as well-defined, solid, hypoechoic or isoechoic masses on US.
• On MRI, they often show homogeneous enhancement after contrast administration and may exhibit T2 hypointensity.

Conclusions:

• Ultrasound and MRI demonstrate characteristic features that can suggest the diagnosis of angioleiomyoma.
• These imaging modalities are valuable tools for the non-invasive evaluation of superficial soft tissue tumors.
