This week’s free board review question…
A 49-year-old man with small-cell lung cancer presents with a new-onset seizure that occurred at home. Computed tomography (CT) of the brain shows a low attenuation area in the right parietal area (see Figure).
Which of the following statements are correct about seizures in patients with cancer?
Seizures are more common with brain tumors in the parietal, temporal, or frontal lobe than the occipital lobe.
High-grade tumors, such as glioblastoma multiforme or metastatic brain tumors, are more likely to cause seizures than low-grade and slow-growing primary brain neoplasms.
The incidence of seizures in patients with brain metastases is 70% to 80%.
Use of chemotherapy may cause seizures.
