Tumor-to-tumor metastasis is a rare but well-known phenomenon. Among the more than 100 intracranial tumors reported, meningiomas are the most common type, whereas schwannoma is extremely rare. ⋯ [(18)F]-fluorodeoxyglucose positron emission tomography is effective in the preoperative diagnosis of rapidly growing cerebellopontine angle tumors in patients with a history of malignancy.

Traumatic brain injury (TBI) is a significant public health problem in the United States, with approximately 1.5-2 million TBIs occurring each year. However, it is believed that these figures underestimate the true toll of TBI. Soccer is the most popular sport in the world and has a following of millions in the United States. Soccer is a sport not traditionally identified as high-risk for concussions, yet several studies have shown that concussion rates in soccer are comparable to, and often exceed those of, other contact sports. As many as 22% of all soccer injuries are concussions. ⋯ In spite of such preventive measures, concussions in soccer will continue to occur. Considering the frequency of concussions in soccer, the serious sequelae of these concussions, and because almost half of concussed soccer players were noncompliant with recommended American Academy of Neurology return-to-play guidelines, further measures must be taken to protect players, in addition to understanding those criteria that result in removing an injured player from competition and the steps by which to safely return an athlete to competition after injury.

As the older segment of the population grows faster than any other age group, the number of elderly diagnosed with glioblastoma is expected to increase. The aim of this study was to explore survival and the treatment provided to elderly patients diagnosed with glioblastoma in a population-based setting. We further studied whether increased treatment aggressiveness may have contributed to a clinically important survival benefit in the elderly population. ⋯ Advancing age remains a very strong and independent negative prognostic factor in glioblastoma. Although there has been an increase in the aggressiveness of treatment provided to elderly with glioblastoma, the gain for the oldest age group seems at best very modest. The prognosis of the oldest age group remains very poor, despite multimodal treatment.
