Background:
The incidence of dural-based metastasis (DBM) is 4% of all patients diagnosed with metastatic cancers. DBM most commonly arises from primary cancers of the lung, breast, and prostate. Most cerebral metastasis lesions are intra axial tumors, whereas a dural base metastasis mimicking meningioma is uncommon.
Case Description:
Here, we are presenting a case report of a 64-year-old woman with a history of treated left breast cancer 14 years ago, who presented to us in the casualty with left lower limb weakness for 1 month and dizziness for 7 days. Magnetic resonance imaging of the brain, plain and contrast, showed a dural-based lesion over the right parieto-occipital region. Patient underwent surgical removal of the lesion, and its histopathological examination (HPE) and immunohistochemistry showed a DBM with primary from the breast.
Conclusion:
This case report discusses the clinical aspects of a case we observed, in which a dural-based metastasis mimicking a meningioma was confirmed on HPE in a previously treated case of breast cancer.
Insights
Dural-based metastasis (DBM) is rare, accounting for 4% of metastatic cancers. This case highlights a DBM from breast cancer mimicking a meningioma, emphasizing the need for thorough diagnosis in recurrent cancer patients.
