Rate of spontaneous resolution of a solitary cysticercus granuloma in patients with seizures.

The rate of spontaneous resolution of a recently diagnosed solitary cerebral cysticercus granuloma as visualized on CT scan was prospectively studied in 210 patients presenting with seizures. The proportion of granulomas that had resolved completely at different time intervals after the index scan was 18.8% at 3 months, 36.4% at 6 months, and 62.5% at 1 year. There is considerable variation in the natural history of a solitary cysticercus granuloma in a patient presenting with seizures.
