Magnetic resonance imaging (MRI) was performed on 3 patients after cryothalamotomy, one of whom had bilateral cryothalamotomies. The time between surgery and MRI ranged from 23 days to 6.5 months. Images made 3 to 4 weeks after surgery showed a lesion of high signal intensity on both T1‐weighted and T2‐weighted images, and an additional central area of low signal intensity on T1‐weighted images. Images obtained at 2, 4, and 6.5 months after surgery showed smaller lesions with low signal intensity on T1‐weighted and T2‐weighted images, a pattern consistent with resolving hematoma after cryothalamotomy.
