Advancements in diffusion-weighted imaging during the past decade have led to the use of diffusion tensor imaging to further characterize the structural integrity of neural tissue and to noninvasively trace neuronal tracts in the brain and spine. This has led to many clinical applications that have aided in surgical planning for brain and spinal cord tumors and has increased the diagnostic potential of magnetic resonance imaging in disorders such as multiple sclerosis, Alzheimer disease, and traumatic brain injury.

The cerebellum is an uncommon location for arteriovenous malformations (AVM) with unique angioarchitecture compared to the cerebrum. We evaluate the outcomes of radiosurgery in a cohort of cerebellar AVMs and assess the effect of infratentorial location by comparing them to a matched cohort of supratentorial AVMs. ⋯ Radiosurgery is an effective treatment modality for cerebellar AVMs with relatively limited adverse events. Infratentorial location did not affect radiosurgery outcomes.

Case Reports
A rare case of recurrent frontal osteoma complicated by mucopyocele with an unusual organism, Moraxella catarrhalis.
We report a rare case of recurrent frontal osteoma complicated by mucopyocele and intracranial abscess. Furthermore, we report an unusual organism, Moraxella catarrhalis, as the infectious agent. Finally, we demonstrate that endovascular embolization may be part of the treatment paradigm of frontal osteomas in selected cases. ⋯ Synchronous presentation of a frontal osteoma with mucopyocele is a rare event. However, the case of a recurrent osteoma complicated by infection with M. catarrhalis has not been reported in the literature, nor a treatment paradigm that included preoperative partial endovascular embolization.
