Rate of recurrence following stereotactic aspiration of colloid cysts of the third ventricle.
The rate of recurrence following stereotactic aspiration of colloid cysts is not defined in the literature. ⋯ Stereotactic aspiration of colloid cysts remains a valid surgical option as complete aspiration leads to a good long-term outcome in several patients. Partial aspiration of the cyst should be followed by excision of the cyst, due to the high rate of symptomatic recurrence. However, periodic follow-up imaging is mandatory even after complete aspiration as delayed recurrences are possible.

Case ReportsGlobus pallidus interna deep brain stimulation improves chorea and functional status in a patient with chorea-acanthocytosis.
We report a 39-year-old woman with chorea-acanthocytosis (ChAc) who was referred with refractory hyperkinetic movement and truncal bending spasm. She was diagnosed with ChAc with clinical features and laboratory findings of acanthocytosis in peripheral blood smear, and genetic studies revealed novel mutations in the VPS13 gene. Because her symptoms did not respond well to medical treatment, she was in a totally dependent state. ⋯ After the operation her hyperkinetic movement, bradykinesia, and truncal bending motion were improved, the preoperative total score of the motor section on the Unified Huntington's Disease Rating Scale (UHDRS) was 44, the independence scale was 50, and functional capacity was 1. However, a year after GPi-DBS, the postoperative score on the motor section was 12, the independence scale was 80, functional capacity was 9, and she had become capable of independent daily life. Although there is currently no curative treatment for ChAc, GPi-DBS represents a promising option for symptomatic control.
