We retrospectively reviewed neuroradiology database at our tertiary-care hospital to search for patients with metaphoric or descriptive signs on brain computed tomography or magnetic resonance imaging. Only patients who had clinical or pathological definitive diagnosis were included in this review.

Head ultrasonography (HUS) remains an important tool in the initial evaluation of intracranial abnormalities in infants. In experienced hands, HUS is an outstanding tool to detect brain abnormalities in preterm and full-term infants, to follow the progression of these lesions, and to describe the maturation of the infant brain. ⋯ In this article we discuss the HUS techniques that are currently available and are now the standard of care, how to perform them, and what to look for. We describe a variety of findings that may be encountered including hemorrhagic complications of prematurity, hypoxic ischemic brain injury, neonatal stroke, infections, malformations, neoplasms, and a few more rare neonatal pathologies.

Diagnosis of Creutzfeldt-Jakob disease during life can be challenging since the huge variability of the symptoms which can be observed, especially in its early stages, may simulate other common forms of dementia. In latest years, noninvasive techniques such as magnetic resonance, positron emission tomography, and single-photon emission tomography have been evaluated to help clinical neurologists to provide a definite diagnosis. We here provide a systematic review of the current knowledge of neuroimaging in CJD in order to establish the actual state of the art.
