Obstructive Jaundice Caused by Metastatic Neuroendocrine Tumor of the Ampulla of Vater in a Young Adult: A Case Report.

Introduction: Ampullary neuroendocrine tumors (NETs) are usually diagnosed in the 5th-6th decades of life, and no cases were reported in <20 years of age. We report a rare case, presenting at a very young age, of well-differentiated NET involving the ampulla of Vater with lymph node metastasis.

Case Presentation: An 18-year-old man presented with a 3-month history of upper abdominal pain and jaundice.

Imaging Genomics and Multiomics: A Guide for Beginners Starting Radiomics-Based Research.

Radiomics uses advanced mathematical analysis of pixel-level information from radiologic images to extract existing information in traditional imaging algorithms. It is intended to find imaging biomarkers related to the genomics of tumors or disease patterns that improve medical care by advanced detection of tumor response patterns in tumors and to assess prognosis. Radiomics expands the paradigm of medical imaging to help with diagnosis, management of diseases and prognostication, leveraging image features by extracting information that can be used as imaging biomarkers to predict prognosis and response to treatment.

Acquired right-sided diaphragmatic hernia in a patient with retroperitoneal hydatidosis: a case report and review of the literature.

Background: Diaphragmatic hernia is primarily congenital in origin and has potentially devastating pulmonary complications. Acquired diaphragmatic hernia as a complication of hydatid disease remains a rare clinical entity. Retroperitoneal hydatidosis, in particular is an exceptionally rare cause behind a similar presentation.

Transurethral Resection for the Treatment of an Inflammatory Myofibroblastic Tumor of the Urinary Bladder: A Case Report.

Inflammatory myofibroblastic tumors (IMT) of the urinary bladder is a remarkably rare bladder tumor. To this day, no standardized treatment protocol has been recognized. Here we report a case of bladder IMT in a 14-year-old girl presenting with urgency, frequency, and gross painless hematuria for a week.

Is primary tumor detectable in prostatic carcinoma at routine contrast-enhanced CT?

Objectives: To determine if prostatic carcinoma (PCa) is detectable at routine contrast-enhanced CT (CECT).

Materials And Methods: With institutional review board approval, 63 consecutive PCa patients underwent CECT before therapy. Two blinded radiologists assessed for rounded focal enhancing peripheral zone nodules.

Prostatic ductal adenocarcinoma: an aggressive tumour variant unrecognized on T2 weighted magnetic resonance imaging (MRI).

Introduction: Prostatic ductal adenocarcinoma (DCa) is an aggressive variant. The purpose of this study was to determine if T2 signal intensity (SI) differs from conventional adenocarcinoma (CCa).

Materials And Methods: A retrospective study of patients who underwent preoperative MRI and prostatectomy between 2009 and 2012 was performed.
