DBS is a typically well‐tolerated operation for treatment of Parkinson's disease, dystonia, and essential tremor ( ET ). Complications related to the surgical procedure and implanted hardware may occur. More commonly reported complications include hemorrhage, seizure, confusion, and infection. In this article, we report on a rare, but important, complication of DBS surgery, a brain cyst formation at the tip of the implanted ventralis intermedius nucleus ( VIM ) DBS lead in 2 patients who underwent the procedure at 2 different centers. The indication for surgery was debilitating ET , and in both cases, there was development of a delayed‐onset neurological deficit associated with an internal capsule/thalamic cystic lesion formation located at the tip of the DBS lead. Case 1 presented within a few months post‐ DBS , whereas case 2 had a 10‐mo delay to onset of symptoms. No clinical and radiological signs of infection were observed and both DBS systems were explanted with uneventful recovery.
