It is reported that 2.3% to 20.4% of patients who have a chronic subdural hematoma (CSDH) develop seizures as a complication. The relationship between the epileptic focus and sulcal hyperintensity on fluid–attenuated inversion recovery (FLAIR) images has been confirmed radiologically.
We recently encountered a patient with CSDH presenting with seizures, with a small hematoma displaying sulcal hyperintensity on FLAIR images.
Case: An 88 year–old man was hospitalized for chronic heart failure at another hospital and he developed transient left hemiplegia. Magnetic resonance imaging (MRI) demonstrated bilateral CSDH and right sulcal hyperintensity on FLAIR images although the right hematoma was thin. Two days later, the patient developed transient left hemiplegia and was referred to our hospital with consciousness disorder. He developed generalized seizures post–admission. We administered antiepileptic drugs and performed middle meningeal artery (MMA) embolization on day 2 of admission. The sulcal hyperintenisty disappeared after 32 days post–operation.
The effectiveness of MMA embolization for CSDH with sulcal hyperintensity on FLAIR images has not been reported previously. We show that middle meningeal artery embolization is effective for CSDH with sulcal hyperintensity on FLAIR.
