Rapidly involuting congenital hemangioma is a rare vascular tumor that generally has a good prognosis. The authors describe a case of a newborn girl with a left cervical vascular lesion. Image exams were performed, and the lesion slowly decreased, leaving redundant skin. Considering all of the findings, a final diagnosis of a rapidly involuting congenital hemangiomas was suspected.

We show that the density profile of a Fermi gas in rapidly rotating potential will develop prominent features reflecting the underlying Landau-level-like energy spectrum. Depending on the aspect ratio of the trap, these features can be a sequence of ellipsoidal volumes or a sequence of quantized steps.

PURPOSE OF REVIEW This article presents a practical and informative approach to the evaluation of a patient with a rapidly progressive dementia (RPD). RECENT FINDINGS Prion diseases are the prototypical causes of RPD, but reversible causes of RPD might mimic prion disease and should always be considered in a differential diagnosis. Aside from prion diseases, the most common causes of RPD are ...
