Gastaut and Fischer-Williams²⁷consider that cases of so-called functional or idiopathic epilepsy (which represent a fault in cerebral function rather than in structure) constitute only about 5% of cases and that most cases of epilepsy have underlying cerebral lesions. These lesions, however, may develop on a "soil" already predisposed to convulsions, which enables a mildly irritative lesion to become markedly epileptogenic. Gastaut^24-26,28has also reviewed our present knowledge of the causes of temporal lobe epilepsy, which is a common form of focal or "partial" epilepsy.^12,24,35,51However, this knowledge is still incomplete, and as Yakovlev⁶⁶has pointed out, various lesions may be responsible. In this paper, therefore, we record the pathological findings in 100 consecutive patients with epilepsy submitted to a unilateral temporal lobectomy, and discuss their origin and their significance.

Case

20:T42f,we used actuarial methods to study outcome after temporal lobectomy in 135 consecutive patients classified into subgroups according to preoperative MRI findings. Sixty months after surgery, 69% of patients with foreign tissue lesions, 50% with hippocampal sclerosis, and 21% with normal MRIs had no postoperative seizures. An eventual seizure-free state of 2 years or more, whether the patient was seizure-free since surgery or not, was achieved by 80% of patients with foreign tissue lesions, 62% of those with hippocampal sclerosis, and 36% of those with normal MRIs. Outcome was worse in those with normal MRIs than in the other two groups. Early postoperative seizures with later remission (the “mming down” phenomenon) occurred in all groups. Late seizure recurrence was present only in the hippocampal sclerosis group. These data show that preoperative MRI is a useful predictor of outcome and that actuarial analysis provides insight into different longitudinal patterns of outcome in MRI subgroups. This information can now be used in preoperative counseling.21:T4fd,Two independent blinded observers reported the preoperative MRIs in a series of 81 consecutive patients with intractable temporal lobe epilepsy who were undergoing temporal lobectomy. We then compar
