✓ The authors report an intrinsic brainstem lesion that was diagnosed initially as a pontine cavernoma, which finally proved to be a choroid plexus papilloma. Choroid plexus papillomas are rare tumors of the central nervous system and are usually intraventricular in location. The occurrence of this tumor in an intraparenchymal location is extremely rare, and its occurrence within the brainstem is previously unreported. The authors also report a trial of chemotherapy with lomustine in the management of the residual tumor.

Middle cerebral artery infarction often occurs at a younger age than other strokes and is associated with significant rates of mortality and morbidity. After a period of pessimism regarding decompressive hemicraniectomy in the management of acute stroke, the method has reemerged in the past decade. The present study was undertaken to assess the immediate and long-term outcome of this intervention and to help better define the selection criteria for surgery.

Methods

The authors conducted a nonrandomized prospective study using decompressive hemicraniectomy with duraplasty in patients at various stages of clinical deterioration due to a space-occupying middle cerebral artery infarct. Patients were assessed at 6 and 12 months postinfarction by using functional scales. Subjective reconsideration was assessed using a questionnaire.

Twenty-six patients were included in the study. The mean age was 48.4 ± 11.2 years, and the mean preoperative Glasgow Coma Scale score was 9.9 ± 3.2. The median time from ictus to surgery was 54 hours (range 13–288 hours). The rate of survival at 1 year postsurgery was 73%. Among survivors, 33.3% were independent (Barthel Index [BI] > 95) and 55.6% were partially dependent (BI 60–95) at 1 year postsurgery, with 72% attaining the ability to walk independently by 1 year postsurgery. No patient remained in a vegetative state. The 1-year BI score was inversely related to patient age (r = − 0.47, p = 0.048).

Conclusions

Survival after decompressive hemicraniectomy was better than previously reported using medical management alone. A vegetative state was avoided and functional independence was possible, especially in younger patients. Increasing age was a statistically significant predictor of disability and long-term functional dependence.
