Histological evaluation of a peripheral nerve is often the final diagnostic work-up for a neuropathy of unknown origin, and a distal sensory nerve is usually biopsied. Here, we report the case of a female patient with painful unilateral neuropathy in the upper arm. According to the histological evaluation of the pronator teres motor branch, vasculitis seemed to be the most probable cause of the...

OBJECTIVE To evaluate the intra-/interobserver agreement of the visual interpretation of contrast-enhanced ultrasound (CEUS) of pancreatic head lesions and its concordance with the histological test results. MATERIAL AND METHODS Two observers (A + B) evaluated by simple visual interpretation 40 consecutive CEUS examinations of pancreatic head lesions and one of the observers evaluated the exa...

Prenatal development of the human brain from undifferentiated neuroepithelium, crosses numerous steps towards primordial organization and subsequent cytoarchitectural layering, ascending and progressive from the lower cortical layers to the superior ones.
