Insights

Toxic leukoencephalopathy can be a reversible side effect of chemotherapy. Magnetic resonance imaging (MRI) is crucial for detecting this white matter disease, as shown in two cases of methotrexate and 5-fluorouracil treatment.

Area of Science:

  • Neurology
  • Radiology
  • Oncology

Background:

  • Leukoencephalopathy is a progressive white matter disorder resulting from myelin damage.
  • Chemotherapy is an uncommon but significant cause of reversible leukoencephalopathy.
  • Early detection of leukoencephalopathy is vital for patient outcomes.

Observation:

  • This study presents two cases of toxic leukoencephalopathy.
  • The patients received chemotherapy involving methotrexate and 5-fluorouracil.
  • Magnetic resonance imaging (MRI) was utilized for evaluation.

Findings:

  • Conventional and diffusion-weighted MRI are effective for diagnosing leukoencephalopathy.
  • MRI revealed characteristic white matter changes consistent with toxic insult.
  • The findings highlight the role of neuroimaging in identifying chemotherapy-induced leukoencephalopathy.

Implications:

  • Neuroimaging, particularly MRI, is essential for the early diagnosis of chemotherapy-induced leukoencephalopathy.
  • Recognizing this condition allows for timely intervention and potentially reversible outcomes.
  • Understanding the radiological features aids clinicians in managing patients undergoing specific oncological treatments.
