As a noninvasive imaging modality able to show the dynamic changes in neurologic activity, functional magnetic resonance imaging has revolutionized the ability to both map and further understand the functional regions of the brain. Current applications range from neurosurgical planning to an enormous variety of investigational applications across many diverse specialties. The main purpose of this article is to provide a foundational understanding of how functional magnetic resonance imaging is being used in research by outlining the underlying basic science, specific methods, and direct investigational and clinical applications.

Although the morphology of the disease is well described, MC presenting at unusual sites can exhibit atypical morphology, resulting in misdiagnosis. This observational, retrospective case series discusses the novel morphology of MC presenting in the intergluteal cleft of five children seen in the outpatient dermatology clinic of an academic medical center.
