Single small enhancing CT lesions (SSECTL) have been very commonly encountered in clinical practice. These lesions typically are small (often < 20 mm), enhancing as a ring lesion or a disc and with varying amounts of surrounding edema. Most SSECTL present as focal seizures. Once the diagnosis of SSECTL and likely to be a solitary cysticercus lesion is made, the patient is given appropriate AED therapy. Depending on the resolution pattern on repeat imaging performed at intervals not less than six months if patient remains asymptomatic, cysticidal therapy is instituted along with AEDs. Any deviation from the classical clinical or radiological patterns needs further evaluation and other etiologies described for the SSECTL will need to be ruled out, including that of tuberculosis. Largely these lesions resolve and the clinical condition remains benign and in most patients AEDs can be withdrawn in two to three years period.
单个小的增强CT病变（SSECTL）在临床实践中非常常见。这些病变通常较小（常<20mm），表现为环形或盘状增强，周围有不同程度的水肿。大多数SSECTL表现为局灶性癫痫发作。一旦诊断为SSECTL且可能为孤立性囊尾蚴病变，就给予患者适当的抗癫痫药物（AED）治疗。如果患者无症状，根据间隔不少于6个月进行的重复成像的消退模式，在给予AED的同时开始杀虫治疗。任何偏离经典临床或放射学模式的情况都需要进一步评估，需要排除SSECTL的其他病因，包括结核病。这些病变大多会消退，临床状况保持良性，大多数患者在两到三年内可以停用AED。
