Multimodality imaging of breast hematomas and their mimickers

Area of Science:

• Radiology
• Medical Imaging
• Oncology

Background:

• Breast hematomas are frequently encountered but often present with underrecognized imaging features.
• Acute hematomas are typically diagnosed with a history of trauma, surgery, or biopsy, but subtle trauma or fat necrosis can complicate diagnosis.
• Increasing use of advanced imaging like MRI and PET/CT leads to incidental detection, mimicking malignancies.

Purpose of the Study:

• To review the natural history and diverse imaging manifestations of breast hematomas.
• To differentiate breast hematomas from other breast conditions, including malignancies.
• To highlight scenarios necessitating histopathological correlation for accurate diagnosis.

Main Methods:

• Pictorial review of breast hematoma imaging.
• Analysis of imaging features across different stages and etiologies.
• Comparison with malignant breast lesions and benign mimics.

Main Results:

• Breast hematomas exhibit varied imaging characteristics depending on their age and association with conditions like fat necrosis.
• They can mimic malignant breast masses, leading to potential misdiagnosis.
• Distinguishing hematomas from malignancies is crucial, especially when incidental findings occur.

Conclusions:

• Understanding the imaging spectrum of breast hematomas is vital for accurate diagnosis and avoiding unnecessary interventions.
• Radiologists must be aware of the potential for breast hematomas to mimic malignancies.
• Histopathological correlation is essential in ambiguous cases to ensure correct patient management.
