    ObjectiveThe goal of this study was to discuss the surgical indications, surgical approaches, and prognostic factors of cerebellar cavernous malformation (CM).MethodsWe retrospectively reviewed the presentation, surgery, and outcome of 58 consecutive patients who underwent resection of cerebellar CMs between 2009 and 2013 in our center.ResultsThe study population consisted of 31 males and 27 females, mean age 39.9 years. Fifty-eight patients experienced 67 symptomatic hemorrhages. The median diameter of all lesions was 2.2 ± 0.9 cm (range, 0.8-4.8 cm). The locations were classified into 3 groups: group 1, cerebellar hemisphere (17 cases, 29.3%); group 2, vermis (18 cases, 31.0%); and group 3, cerebellar peduncle (23 cases, 39.7%). Complete resection was achieved in all patients without surgical mortality. Postoperatively, 11 patients developed new surgical complications, including facial paralysis in 6 patients, ataxia in 2 patients, dizziness in 2 patients, and decrease in facial sensation in 1 patient. The mean modified Rankin Scale (mRS) at final follow-up was significantly improved compared with the preoperative score (0.5 ± 0.5 vs. 1.4 ± 0.7, P = 0.035). The symptoms and neurologic deficits improved in most patients. The lesion location was the only factor that predicted a worse outcome, and the mRS was significantly lower in group 3 than groups 1 and group 2 (P = 0.019).ConclusionsPatients with cerebellar CMs usually achieve favorable outcomes via surgery. Cerebellar peduncle CMs cause significantly more neurologic deficits than other locations. A reasonable surgical approach and meticulous manipulation are necessary to prevent impairment of neurologic function.Copyright © 2015 Elsevier Inc. All rights reserved.
