Patients With Epilepsy

OBJECTIVE: To determine the frequency of temporal lobe hypogenesis (TLH) associated with arachnoid cysts (AC) in patients with epilepsy. METHOD: We retrospectively revised 655 consecutive MRI scans from patients followed in our epilepsy clinic. We identified patients with temporal AC and then performed careful visual analysis in a workstation. Patients with evident expansive or destructive lesions were excluded. RESULTS: Only 4 (0.6%) patients had AC in the left temporal lobe, all associated with TLH. In addition, there were also ipsilateral dysgenetic characteristics in the ipsilateral hippocampus including abnormal shape and axis, and hyperintense T2 signal. In one patient this hippocampal abnormality was bilateral. CONCLUSION: AC with TLH was rarely found in our patients with epilepsy and it was always associated with hippocampal dysgenesis. Although volumetric reduction of the temporal lobe can be observed in patients with epilepsy and hippocampal abnormalities, the presence of adjacent AC points to a malformative etiology.

State Examination

Magnetic resonance imaging (MRI) was used in patients with epilepsy and psychosis. From 50 patients with epilepsy, a subgroup of 12 patients were categorised by the Present State Examination (PSE) as having nuclear schizophrenia (NS) and then compared with an epileptic control group with no psychiatric history. Further, patients with hallucinations were compared with patients without hallucinations. No differences in T1 relaxation times in any regions of interest were noted in the NS group compared with the other group. However, patients with hallucinations had a significantly higher T1 value in the left temporal lobe. These findings support the concept that specific abnormalities in limbic system structures relate to the phenomenology of the psychoses of epilepsy, especially left temporal lobe epilepsy.

Arachnoid cysts are considered a rare neurological tumor, few of which exhibit any symptomatology. A 38-year-old Haitian American female with no past psychiatric history presented with rapid onset of psychosis. Workup for medical etiology proved to be within normal limits, with the exception of a left temporal lobe arachnoid cyst. The purpose of this paper is to add to a number of existing case reports that suggest a relationship between such lesions and psychiatric illness.
