Cystic lesions of the pancreas are increasingly recognized. While some lesions show benign behaviour (serous cystic neoplasm), others have an unequivocal malignant potential (mucinous cystic neoplasm, branch- and main duct intraductal papillary mucinous neoplasm and solid pseudo-papillary neoplasm). European expert pancreatologists provide updated recommendations: diagnostic computerized tomogr...

Benign liver tumors are common lesions that can be classified into cystic and solid lesions. Cystic lesions are the most frequent; however, they rarely represent a diagnostic or therapeutic challenge. In contrast, solid lesions are more difficult to characterize and management remains controversial. The wide availability and use of advanced imaging modalities, including ultrasonography, compute...

S16 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 for cases which require immunohistochemistry, for example, neuroendocrine tumor, lymphoma, and mediastinal tumors. (3) EUS is the most important tool for pancreatic cystic lesions. (4) EUS is an important tool for diagnosis of CBD and gallbladder masses. EUS gives accurate diagnosis in gastric submucosal lesions, infiltrative gas...

Aim: To determine the rate of malignancy in complex renal cystic lesions. Material and methods: We studied 111 patients both male female above age 18 years with lesions classified as Bosniak category IIF, III, IV on CT. Patients categories I II were excluded from study. The was analyzed. Results: mean 47.58±15.05 years. 27% 29.7% III 43.2% IV. overall 62.2% all who presented IIF,III 33.3%, 54.5...

Pancreatic tumors can be classified by their morphologic features on CT. The subtypes include solid tumors, mixed cystic and solid lesions, unilocular cysts, multilocular cystic lesions, and microcystic lesions. Endoscopic US and MRI can provide detailed information for classifying pancreatic lesions. Each subtype has different kinds of tumors and malignant potential, thus the classification ca...

Introduction: Magnetic resonance imaging (MRI) is an established technique for the evaluation of intracranial mass lesions. It is highly sensitive yet relatively nonspecific. It is not always possible to characterize these lesions on MRI. In-vivo MR spectroscopy (MRS) has shown its utility in the differential diagnosis of cystic intracranial mass lesions (1-3). The results of these studies are ...

Cherubism is a rare genetic disorder resulting in the replacement of mandible and sometimes maxilla with expansile cystic lesions. The usually presents childhood, eventual quiescence early adulthood. We report case cherubism involving both complicated by mass effect on nasal cavity left orbit. Pathologic features, clinical considerations, treatment are discussed.&nbsp

The present study describes the findings from three cases of peripheral primitive neuroectodermal tumors (PNETs) diagnosed using computed tomography (CT) or magnetic resonance imaging (MRI). The patients were all diagnosed with PNETs of the peripheral central nervous system. All the lesions were soft-tissue masses with cystic degeneration. The CT images revealed that the lesions were large and ...

PURPOSE To describe the CT and MR findings of various entities causing cystic expansile masses in the maxilla and the significance of the cortical bony plate between the lesions and sinus cavities in the differential diagnosis. METHODS CT findings of 28 patients with cystic expansile masses of the maxilla, including 20 cases of maxillary mucoceles (17 postoperative mucoceles, 2 mucoceles of a...
