Meningeal hemangiopericytoma (HPC) is a rare, aggressive central nervous system tumor that tends to invade locally and to metastasize, and has a high rate of recurrence. ⋯ Strategies combining adjuvant radiation with tumor resection seemed to hinder tumor progression, but had no effect on OS or the development of metastases. Greater extent of resection was associated with increased OS (log-rank, P < .05). Anaplastic HPC was associated with reduced OS and with reduced recurrence interval (log-rank, P < .05).

Poor outcome and neuropsychological sequelae after aneurysmal subarachnoid hemorrhage (SAH) is a persistent problem. Pituitary dysfunction has been proposed as a contributing factor. Clinical studies have given variable and conflicting results on its importance and incidence after SAH. The aim of this study was to prospectively examine SAH patients with assessment of endocrine function in the acute stage and at early follow-up and to compare clinical SAH features to endocrine abnormalities indicating pituitary dysfunction. ⋯ The present results support earlier findings that hormonal abnormalities are not infrequent after SAH. Furthermore, our data suggest that pituitary dysfunction is associated with worse clinical outcome and is more common among patients with bleeding sites close to the hypothalamus.

To analyze the safety and efficacy of neuroendoscopic colloid cyst resection and to assess patient satisfaction. ⋯ Neuroendoscopic colloid cyst resection can reliably achieve complete lesion removal with short operative times. In addition, there is a high level of reported patient satisfaction. To our knowledge, this is the largest case series of neuroendoscopic colloid cyst resections from a single surgeon.
