Forced thinking (FT) is a rare epileptic phenomenon which is usually seen in patients with frontal lobe epilepsy. We report a rare case of mesial temporal lobe epilepsy presenting FT as simple partial status epilepticus. A 50-year-old woman with left hippocampal sclerosis developed a prolonged episode of continuous FT for five days after she experienced a clustering of complex partial seizures during the period of preoperative video-electroencephalography (EEG) monitoring. The EEG demonstrated continuous focal ictal discharges in the left foramen ovale electrodes. Positron emission tomography showed focal glucose hypermetabolism in the left mesial temporal region. This case indicates that the anatomical substrate for the development of FT is located in the mesial temporal region as well as the frontal lobe, and prolonged FT can occur as a seizure manifestation.
强迫思维（FT）是一种罕见的癫痫现象，通常见于额叶癫痫患者。我们报告一例罕见的内侧颞叶癫痫病例，其以强迫思维作为单纯部分性癫痫持续状态。一名50岁患有左侧海马硬化的女性，在术前视频脑电图（EEG）监测期间经历了一系列复杂部分性发作后，出现了持续5天的强迫思维延长发作。脑电图显示左侧卵圆孔电极处有持续的局灶性发作期放电。正电子发射断层扫描显示左侧内侧颞叶区域有局灶性葡萄糖代谢增高。该病例表明，强迫思维发生的解剖学基础位于内侧颞叶区域以及额叶，并且强迫思维延长发作可作为癫痫发作的一种表现形式出现。
