Although cystic tumors of the pancreas are relatively rare, they constitute an increasingly important category. Advances in imaging and interventional techniques and the sharp drop in the mortality rate of pancreatic surgery have rendered pancreatic biopsies and resections commonplace specimens. Consequently, in the past two decades, the nature of many cystic tumors in this organ has been bette...

OBJECTIVE: To demonstrate the most frequent features of cystic breast lesions at ultrasound elastography, discussing the applicability of this method. MATERIALS AND METHODS: The present casuistic included 150 patients referred for percutaneous breast biopsy of 175 lesions. Histologically diagnosed solid lesions (153 lesions) were excluded; lesions histologically diagnosed as cystic (22 lesions)...

Background: Virchow-Robin (VR) spaces are the fluid-filled perivascular spaces adjacent the brain vessels. The signal intensities of the VR spaces are very similar to those of cerebrospinal fluid (CSF). VR spaces should be distinguished various pathologic conditions, including lacunar infarctions, cystic periventricular leukomalacia, cryptococcosis, cystic neoplasms and neuroepithelial cysts. C...

BACKGROUND The early determination of premalignant lesions of pancreas can prevent unnecessary excessive surgical procedures and can reduce morbidity and mortality. Pancreatic intraepithelial neoplasia-3 (PanIN-3) is a preinvasive form of adenocarcinoma (carcinoma in situ). PanINs have not taken place in the literature of radiology yet, it should be considered in differential diagnosis of pancr...

Cystadenoma of the liver is a rare neoplasm. Although many cystadenomas are asymptomatic, symptoms can include abdominal pain, postprandial epigastric discomfort, and nausea. Dramatic changes in hepatic imaging techniques have been helpful for diagnosing cystic lesions of the liver, such as simple cyst, hydatid cyst, cystadenoma, cystadenocarcinoma, and metastatic neuroendocrine tumors. However...

the papillary cystadenoma lymphomatosum (pcl), also called warthin's tumor, is a benign salivary gland tumor which primarily involves the parotid gland. these lesions are composed of a double layer of cuboidal or culmnar eosinophilic cells lining a cystic cavity which lymphoid tissue is present in the supporting stroma. the lesions shows a predilection for males, with peak incidence during...

Cystic lymphangiomas are benign colonic neoplasms arising from the submucosa. Traditionally, endoscopic resection has been described for smaller lesions, while surgery is reserved for larger symptomatic lesions. We present a case of a 69-year-old asymptomatic individual noted to have a cystic lymphangioma of the colon measuring 5 cm, which was successfully removed with endoloop endoscopic resec...
