BACKGROUND: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an established treatment for patients with Parkinson disease. One adverse event is the development of postoperative confusion. The aim of this study was to report the incidence and associated factors of postoperative confusion after STN DBS surgery. METHODS: This was a retrospective cohort study by chart review of patients with Parkinson disease who underwent STN DBS in a Brazilian public academic hospital from January 2013 to October 2017. The primary outcome was the incidence of postoperative confusion. The association of the outcome and imaging and clinical variables was evaluated. RESULTS: Among 49 patients who underwent STN DBS for Parkinson disease, the incidence of postoperative confusion was 26.5% (95% confidence interval 15%-41.1%). Univariate analysis identified the following variables associated with development of confusion: age (63.2 ± 7.8 years vs. 55.4 ± 9.1 years, P = 0.009), disease duration (16.5 ± 5.1 years vs. 13.2 ± 4.2 years, P = 0.027), Charlson comorbidity index (2 [interquartile range 1-3] vs. 1 [0-1 interquartile range], P = 0.002), width of the third ventricle (5.4 ± 2.1 mm vs. 4 ± 1.6 mm, P = 0.018), and cella media index (5 ± 1 vs. 5.6 ± 0.8, P = 0.018). After adjustment, Charlson comorbidity index remained significant (adjusted relative risk 1.64, 95% confidence interval 1.17-2.3, P = 0.004). CONCLUSIONS: The incidence of postoperative confusion in this cohort was 26.5%. After analysis of confounding factors, the Charlson comorbidity index was significantly associated with postoperative confusion.

BACKGROUND: Congenital hemangiomas are benign vascular tumors, and the intracranial counterpart was described in very few cases. CASE DESCRIPTION: A newborn presented with an intracranial tumor associated with an arachnoid cyst, diagnosed by antenatal ultrasound at 37 weeks of gestation. Surgery was indicated due to increased head circumference and bulging fontanelle, and a complete resection of an extra-axial red-brown tumor was performed at the 3(rd) week of life. Microscopy revealed a hemangioma. CONCLUSION: Hemangioma is a rare differential diagnosis that must be considered in extra-axial intracranial tumors affecting infants and neonates. The radiological features are not helpful in differentiating from other tumors, and surgery is indicated when the diagnosis is uncertain or whenever there are signs of increased intracranial pressure.
