The aim of this study was to identify the clinical, electrophysiological and neuroimaging characteristics of patients with medically refractory symptomatic parietal lobe epilepsy. These findings may help us to localize the seizure focus in some patients with cryptogenic partial epilepsy and warn clinicians when the parietal lobe should be sampled with more invasive techniques like intracranial electrodes prior to epilepsy surgery.
We performed a retrospective, descriptive study of patients who underwent a comprehensive evaluation including clinical, electroencephalographic and neuroimaging procedure for intractable lesional parietal lobe epilepsy for 11 years at the Department of Neurology of our hospital.
Patients admitted to our clinic with medically refractory seizures and diagnosed as lesional parietal lobe epilepsy were included in this descriptive study.
Here we presented the clinical and laboratory findings of 46 lesional symptomatic parietal lobe epilepsy patients.
This may explain the mislocalization of non-lesional parietal lobe epilepsy to other lobes in some cases.
This finding contradicts with the literature, where aura is reported in up to 90% of the patients with tumoral parietal lobe epilepsy. The reason for this discrepancy may be the low number of tumoral patients in our study
In conclusion, clinical and laboratory findings of patients with parietal lobe epilepsy are scarce in the literature.
