Introduction:
Several adverse events have been associated with the use of bevacizumab during the treatment of neoplasms such as colorectal cancer, breast cancer, non-small cell lung cancer, pancreatic cancer and renal cell carcinoma. The present case demonstrates how focal neurological symptoms lead to the magnetic resonance imaging-based differential diagnosis between focal parenchymal metastases and microischemic phenomena, with crucial implications for patient management.
Case Presentation:
We describe the case of a 37-year-old Italian Caucasian woman with metastatic colon cancer who developed focal neurological symptoms during a chemotherapy regimen involving the use of bevacizumab. Brain magnetic resonance imaging examination revealed millimetric lesions with restricted diffusion without perilesional edema or contrast enhancement after gadodiamide intravenous injection, suggestive of acute microischemic phenomena. This complication is very rare but clinically significant.
Conclusion:
The differential diagnosis in patients with cancer undergoing bevacizumab treatment should include microischemic phenomena.
