One exceptionally rare complication of spine surgery is a remote cerebellar hemorrhage, which is defined as a hemorrhage that is remote from the site of surgery, either in the cranium or the spinal column. The existence of a remote cerebellar hemorrhage has been reported by several authors,1–3 and it appears to be more common after supratentorial surgery rather than spine surgery. Haller et al ...

Medulloblastoma is the most common malignant and uncontrollable childhood brain tumor. This tumor is observed in patients of all ages, reaches a peak in children between 3 and 9 years old, and it is also the most common malignant cerebellar tumor in infants. It accounts for 1% to 2% of all brain tumors in adults. By definition, medulloblastomas arise in the posterior fossa, but histologically s...

OBJECT Although the traditional nomenclature used to describe hindbrain hernias is useful, there are certainly patients in whom these morphological entities do not strictly apply. One such group is composed of patients with the more recently described Chiari 1.5 malformation in which a Chiari I malformation is seen in combination with brain-stem herniation through the foramen magnum. In an atte...

BACKGROUND AND PURPOSE Bone wax is a hemostatic agent that has been reported in some instances to migrate into the sigmoid sinus following posterior fossa surgery. The purpose of this study was to characterize the CT and MR imaging findings of this entity. MATERIALS AND METHODS The study included 212 consecutive patients who underwent posterior fossa surgery and postoperative CT and contrast-...

Brain tumors are the leading cause of death and disability from childhood disease in developed countries. Pediatric posterior fossa tumors are often effectively controlled with a combination of surgery, radiation, and chemotherapy, depending on tumor type. White matter injury following resection of tumor and radiation treatment is associated with cognitive declines, including working memory def...
