Stellate images: anatomic and radiologic correlations.

Area of Science:

• Radiology
• Oncology
• Pathology

Background:

• Stellate images are a common mammographic finding, often associated with breast cancer.
• While typically indicating malignancy, stellate images can also be caused by benign breast conditions.
• Accurate interpretation requires high-quality mammograms and correlation with other diagnostic methods.

Purpose of the Study:

• To correlate malignant and benign stellate images with pathological findings.
• To evaluate the significance of stellate images in detecting non-palpable breast lesions.
• To establish guidelines for managing patients with stellate images on mammography.

Main Methods:

• Mammographic-pathologic correlation of stellate lesions.
• Review of cases with stellate findings on mammography.
• Analysis of diagnostic workup including clinical examination, ultrasound, and cytology.

Main Results:

• Stellate images are frequently associated with malignancy but can also stem from benign conditions like fibrosis and elastosis.
• Distinguishing benign from malignant spicules solely on mammography is challenging.
• Stellate images play a vital role in identifying non-palpable breast cancers.

Conclusions:

• Stellate images warrant suspicion for malignancy until proven otherwise.
• A comprehensive diagnostic approach, including imaging and biopsy, is essential for definitive diagnosis.
• Guidelines are proposed to aid in the management of stellate mammographic findings.
