Abstract:
We describe a patient with metastatic disease to an intracranial meningioma in which MR images showed multiple foci of intense enhancement within a background of moderate enhancement. The discrete foci proved to be metastatic disease from the patient's known breast carcinoma.
Insights
Metastatic breast carcinoma can spread to intracranial meningiomas, appearing as distinct enhancing lesions on MRI scans. This case highlights the importance of considering metastatic disease in meningioma imaging.
Area of Science:
- Neurology
- Oncology
- Radiology
Background:
- Intracranial meningiomas are common primary brain tumors.
- Metastatic disease to the brain is a significant clinical challenge.
Observation:
- A patient presented with an intracranial meningioma.
- Magnetic resonance imaging (MR) revealed multiple areas of intense enhancement within the tumor.
- These intense foci were superimposed on a background of moderate enhancement.
Findings:
- The discrete enhancing foci on MR imaging were confirmed to be metastatic disease.
- The origin of the metastatic disease was identified as the patient's known breast carcinoma.
Implications:
- This case underscores the potential for breast cancer metastasis to meningiomas.
- Radiologists should consider metastatic disease when encountering heterogeneous enhancement patterns in meningiomas.
- Accurate diagnosis is crucial for appropriate patient management and treatment planning.
