Radiation-induced malignant gliomas (RIMGs) are known uncommon risks of brain irradiation. We describe 4 cases of RIMG that occurred at our institution and conduct the largest comprehensive review of the literature to characterize RIMGs better. ⋯ The risk of RIMG appears to be the same for all age groups, histologies, and RT dosages. Although the risk is low, patients should be aware of RIMG as a possible complication of brain irradiation.

Impaired systemic hormonal activity caused by hypothalamic and pituitary injury may contribute to neuropsychologic disturbances and poor quality of life after aneurysmal subarachnoid hemorrhage (SAH). This prospective study was designed to longitudinally evaluate long-term clinical outcome and pituitary function after SAH using dynamic tests for adrencorticotropic and somatotropic secretory capacity. ⋯ Application of dynamic endocrine tests revealed a high frequency of long-term hypothalamic-pituitary dysfunction after aneurysmal SAH. The role of pituitary dysfunction in the recovery after SAH merits further evaluation.
