To compare magnetic resonance (MR) elastography and ultrasonographic shear-wave ( SWE ) for the staging of hepatic fibrosis HF in same individuals.This prospective study was approved by institutional review board, informed consent obtained from all patients. The technical success reliable liver stiffness LS measurement rates at MR were compared 129 patients who underwent both examinations. For mutual validation, values measured examinations correlated using Pearson correlation. diagnostic...
In this report, we present a rare case of primary signet-ring cell carcinoma the appendix in 51-year-old woman with right lower quadrant pain. Since non-specific concentric appendiceal wall thickening was found radiologic evaluation, it misdiagnosed as non-tumorous appendicitis. An in-depth examination correlation between sonographic and histopathologic findings demonstrated that single markedly thickened hypoechoic layer well correlated diffuse infiltration tumor cells both submucosal...
This study aimed to determine the incremental value of using a structured report (SR) for US examinations pediatric appendix.Between January 2009 and June 2016, 1150 patients with suspected appendicitis who underwent appendix were included retrospectively. In November 2012, we developed five-point scale SR examinations. The divided into two groups according form report: free-text or SR. primary clinical outcomes compared between groups, including rate CT imaging following examinations,...

Supradiaphragmatic liver is a rare condition. Establishing an accurate preoperative diagnosis difficult. Operative exploration necessary to differentiate this lesion from intrathoracic masses, such as pleural based tumor, diaphragmatic tumor and peripheral lung tumor. However, with the aid of hepatocyte-specific magnetic resonance imaging contrast agent, gadoxetic acid (Gd-EOB-DTPA), functional hepatocytes in can be identified hepatobiliary phase, potentially allowing non-invasive diagnosis....
A malignant fibrous histiocytoma of the mesentery is rare, and multifocal involvement as a primary tumor very rare. In this report, case presenting with two masses multiple peritoneal seeding in 48-year-old man described. physical examination revealed large, firm, non-tender mass right lower abdomen patient. Computed tomography lesion partially, indistinctly marginated heterogeneously enhancing irregular peritumoral strands abdomen, while sonograms an ill-defined low-echoic mass. The final...
Primary rectal syphilis is a rare disease that can be misdiagnosed as lymphoma or other cancers on sigmoidoscopy CT. Here, we report case of primary mimicking malignancy in 23-year-old male who presented with mass and multiple lymphadenopathies. In this literature review, focused the CT findings endoscopic observations syphilis. Infectious diseases, such syphilis, should considered differential diagnosis young patients unusual lesions disproportionately extensive
Background Acute gangrenous cholecystitis, a severe complication of carries high risk morbidity and mortality. Despite its severity, preoperative diagnosis is challenging, often only confirmed during surgery. Therefore, we analyzed various factors that could predict acute cholecystitis in patients undergoing cholecystectomy.
Extrapulmonary small cell carcinoma is a rare neoplasm. It highly aggressive, malignant tumor with rapid local progression and early metastasis. We report case of arising in the rectum that presented as bowel habit change 57-year-old man. Physical examination revealed firm, fixed mass rectum. Computed tomography circumferential bulky an irregular margin perirectal fat infiltration enlarged regional lymph nodes. Histologic resected was consistent
To identify the features that can be used for differentiating appendicitis from non-appendicitis in pediatric patients with equivocal ultrasound (US) results.A total of 53 (≤ 18 years old) results on US examination suspected between November 2012 and October 2017 were included. evaluation was conducted based information retrieved a predefined structured report form. Then, likelihood prospectively classified into five categories. The considered as grade 3 (indeterminate) 4 (probably...
Mucosa-associated lymphoid tissue (MALT) lymphomas are an extranodal subset of marginal zone B-cell and represent > 8% all types (1). In 1983, Isaacson Wright (2) initially described MALT as a distinctive type lymphoma arising in the gastrointestinal tract. can be found at mucosal sites such stomach, lung, salivary gland or from sites, which share embryologic origin with mucosa thyroid that normally lacks organized (3). Primary hepatic is extremely rare lesion, only 45 cases reported English...
Background/Aims: To investigate the diagnostic performance of diffusion-weighted imaging (DWI) for hepatic neuroendocrine tumors (NET) compared with combined DWI and contrastenhanced magnetic resonance (MRI) .MethodsFifteen patients NET (n=128) underwent enhanced MRI multiple-b values. We analyzed three different sets: Precontrast set; set (added DWI); image). Two reviewers rated possibility using a 5-point scale each image set. Their was Jackknife alternative free-response ROC...
An ilio-iliac arteriovenous fistula (AVF) is rare. Common factors leading to AVF include congenital malformations, iatrogeny, and trauma. There limited documentation in the literature of cases involving with May-Thurner syndrome. Here, we present a case an syndrome 80-year-old male. CT angiography confirmed extensive AVF. Successful endovascular procedures for were performed using several variable-sized coils 1400-2000 µm gelatin particles. After embolization, follow-up abdominopelvic...
