Contribution of endosonography in an uncommon case of pancreatic cysts

Here we present the case of a 35-year-old female patient with long standing dyspepsia and imaging studies showing the presence of multiple cysts in the head and tail of the pancreas. The patient underwent endosonography that confirmed the presence of multiple simple cysts throughout the entirety of the pancreas without dilation of the pancreatic duct. The majority of the cysts were less than one centimeter in size, and the largest cyst showed a honeycomb appearance.Cytology of aspirates from the two largest cysts was compatible with benign pancreatic cysts. Endosonography also revealed cysts within the left kidney and spleen. Genetic testing confirmed Von Hippel-Lindau disease. We highlight this case because it is unusual for Von Hippel-Lindau disease, a rare clinical entity, to present solely with cysts in the absence of more common manifestations, such as hemangioblastomas in the central nervous system and malignancy.

迎接新一代移动设备模数转换器的低功耗、高速度和高性能设计挑战

消费者对于功能、速度、网络访问的便捷性以及电池寿命的要求正在不断提升，这就要求电子系统必须快速发展以实现更高的性能和更快的运行速度，同时还要维持低功耗。模数转换器（ADC）是所有消费类电子设备中所普遍采用的基本构成模块，它的作用是将模拟信号转换为可处理的数字信号。
