Primary hepatic angiosarcoma mistaken for a giant hemangioma.

Primary hepatic angiosarcoma (PHA) is a rare hepatic mesenchymal tumor that accounts for 2% of all primary malignant liver tumors. It typically presents with nonspecific symptoms, is highly aggressive, and there are limited treatment options. Imaging characteristics of PHA overlap with that of hepatic hemangioma, a common benign hepatic lesion, creating a potential diagnostic pitfall.

Cancer Risk in Thyroid Nodules: An Analysis of Over 1000 Consecutive FNA Biopsies Performed in a Single Canadian Institution.

To determine the cancer risk in thyroid nodules using ACR TI-RADS. A retrospective analysis of all thyroid biopsies was performed over a 3-year period (2021 to 2023). Variables including gender, age, history of thyroid cancer or neck irradiation, nodule size and location, TR level, and sonographic features such as punctate echogenic foci (PEF), a very hypoechoic appearance, taller-than-wide shape, and suspected extrathyroidal extension were analyzed.

Size threshold as a risk for malignant transformation in typical ovarian dermoid lesions: a scoping review.

Purpose: The O-RADS malignancy risk stratification of typical ovarian dermoid cysts by using a 10 cm threshold is based on expert consensus rather than analysis of objective clinical data. This comprehensive scoping review consolidated all currently available studies evaluating typical benign ovarian dermoid cyst size and risk for malignant transformation.

Methods: A systematic review of MEDLINE, Embase, Scopus and the Cochrane library was performed from inception to January 14, 2024, using PRISMA-ScR guidelines.

Inferior vena cava leiomyosarcoma mimicking an exophytic intrahepatic cholangiocarcinoma.

Inferior vena cava (IVC) leiomyosarcomas are rare smooth muscle neoplasms that account for 0.5% of adult soft tissue sarcomas. They present with nonspecific symptoms and have poor prognosis.

Re-evaluating Endometrial Thickness in Symptomatic Postmenopausal Patients for Excluding Cancer: Systematic Review and Meta-Analysis.

Purpose: The current ACR and American College of Obstetricians and Gynecologists guidelines recommend a ≤4-mm endometrial thickness threshold for excluding endometrial cancer in symptomatic postmenopausal patients. This systematic review and meta-analysis aims to re-evaluate the optimal endometrial thickness threshold on imaging for excluding cancer in symptomatic postmenopausal patients.

Materials And Methods: A systematic search of MEDLINE, EMBASE, Cochrane Library, and Scopus from inception to October 2023 was performed in addition to a gray literature search.

Abbreviated Multiparametric MR Solution (the "Liver Triple Screen"), the Future of Non-Invasive MR Quantification of Liver Fat, Iron, and Fibrosis.

To review the findings of a multiparametric MRI (the "liver triple screen") solution for the non-invasive assessment of liver fat, iron, and fibrosis in patients with chronic liver disease (CLD). A retrospective evaluation of all consecutive triple screen MRI cases was performed at our institution over the last 32 months. Relevant clinical, laboratory, and radiologic data were analyzed using descriptive statistics.

Ovarian vein syndrome - Rare ovarian vein compression of the ureter.

Ovarian vein syndrome is a rare condition involving the compression of the ureter by the ovarian vein. Since it was first described, very few cases have been reported in literature. We present a case of a 37-year-old female with typical symptoms and common right-side involvement.

Vascular compression syndromes in the abdomen and pelvis: a concise pictorial review.

Vascular compression syndromes are a diverse group of pathologies that can manifest asymptomatically and incidentally in otherwise healthy individuals or symptomatically with a spectrum of presentations. Due to their relative rarity, these syndromes are often poorly understood and overlooked. Early identification of these syndromes can have a significant impact on subsequent clinical management.

Diagnostic accuracy of contrast-enhanced CT versus PET/CT for advanced ovarian cancer staging: a comparative systematic review and meta-analysis.

Purpose: Accurate staging of ovarian cancer is critical to guide optimal management pathways. North American guidelines recommend contrast-enhanced CT as the primary work-up for staging ovarian cancer. This meta-analysis aims to compare the diagnostic accuracy of contrast-enhanced CT alone to PET/CT for detecting abdominal metastases in patients with a new or suspected diagnosis of ovarian cancer.

An open label feasibility study of a nutrition and exercise app-based solution in cirrhosis.

Background: Nutrition and exercise are the mainstay of therapy for the prevention and treatment of frailty in cirrhosis. This pilot study assessed feasibility of the online delivery of an app-based semi-supervised nutrition and exercise intervention in this population.

Methods: The 11-week pilot recruited adults with cirrhosis who owned internet-connected devices.

Cushing's syndrome diagnosed incidentally on CT imaging.

In this case report, we describe an uncommon presentation of Cushing's syndrome in a patient in their 60s who presented to the emergency department with left-sided chest pain. The initial workup for the patient was unremarkable except for an elevated blood pressure and elevated fasting plasma glucose. A CT scan of the chest, abdomen and pelvis was performed, demonstrating a splenic artery thrombus with multiple splenic infarcts, in addition to a combination of macronodular adrenal hyperplasia, bilateral gynecomastia, centripetal fat distribution and suspected mild bone demineralisation.

Two-point Dixon and six-point Dixon magnetic resonance techniques in the detection, quantification and grading of hepatic steatosis.

Background: Hepatic steatosis is a very common problem worldwide.

Aim: To assess the performance of two- and six-point Dixon magnetic resonance (MR) techniques in the detection, quantification and grading of hepatic steatosis.

Methods: A single-center retrospective study was performed in 62 patients with suspected parenchymal liver disease.

Cystic retroperitoneal dedifferentiated liposarcoma: A case report.

Liposarcoma is the most common primary retroperitoneal sarcoma in adults. We report the case of an 86-year-old male who presented to the emergency department with frequent falls and unexplained weight loss that was found to have a cystic retroperitoneal dedifferentiated liposarcoma. Initial computed tomography revealed a large heterogeneous complex cystic hypoenhancing lesion in the left retroperitoneum.

Impact of Size Thresholds on the Diagnosis of Incidental Adrenal Lesions: A Systematic Review and Meta-Analysis.

Background: Preferred size-threshold recommendations for management of incidental adrenal lesions remain controversial.

Purpose: This meta-analysis aimed to compare the diagnostic accuracy of different size thresholds for detecting malignancy in patients with incidental adrenal lesions on imaging.

Materials And Methods: A systematic review of MEDLINE, Embase, Scopus, the Cochrane Library, and the gray literature, covering the period from inception to September 2021, was performed.

Unilateral renal agenesis, blind-ended ureter, and ectopic ureterocele inserting into the seminal vesicle: A very rare developmental association.

Congenital renal anomalies are common imaging findings and can often be detected antenatally. In some cases, these anomalies may go undetected and present in adulthood. We report a very rare case of unilateral renal agenesis in a 22-year-old male associated with an ipsilateral dilated blind-ended ureter that ectopically inserted into the seminal vesicle.

Diagnostic accuracy of CT and MR features for detecting atypical lipomatous tumors and malignant liposarcomas: a systematic review and meta-analysis.

Objectives: This systematic review and meta-analysis evaluated the diagnostic accuracy of CT and MRI for differentiating atypical lipomatous tumors and malignant liposarcomas from benign lipomatous lesions.

Methods: MEDLINE, EMBASE, Scopus, the Cochrane Library, and the gray literature from inception to January 2022 were systematically evaluated. Original studies with > 5 patients evaluating the accuracy of CT and/or MRI for detecting liposarcomas with a histopathological reference standard were included.

Adrenal Neoplasms: Lessons from Adrenal Multidisciplinary Tumor Boards.

The radiologic diagnosis of adrenal disease can be challenging in settings of atypical presentations, mimics of benign and malignant adrenal masses, and rare adrenal anomalies. Misdiagnosis may lead to suboptimal management and adverse outcomes. Adrenal adenoma is the most common benign adrenal tumor that arises from the cortex, whereas adrenocortical carcinoma (ACC) is a rare malignant tumor of the cortex.

Comparing the Denver criteria sets for blunt trauma: a retrospective study of cases in Edmonton, Alberta.

Objective: To determine whether a more conservative Denver criterion set could reduce unnecessary CT angiography (CTA) studies when screening for blunt cerebrovascular injury (BCVI) following blunt trauma.

Methods: Following ethics approval, a retrospective chart review of 447 consecutive patients undergoing emergency CTA at two large teaching hospitals was conducted to determine the presence of risk factors for each Denver criterion set. Imaging studies of adults conducted between January 2016 and June 2020 containing sufficient clinical information for accurate classification were included in the study.

Multiparametric MR assessment of liver fat, iron, and fibrosis: a concise overview of the liver "Triple Screen".

Chronic liver disease (CLD) is a common source of morbidity and mortality worldwide. Non-alcoholic fatty liver disease (NAFLD) serves as a major cause of CLD with a rising annual prevalence. Additionally, iron overload can be both a cause and effect of CLD with a negative synergistic effect when combined with NAFLD.

Reliability of ultrasound ovarian-adnexal reporting and data system amongst less experienced readers before and after training.

Background: The 2018 ovarian-adnexal reporting and data system (O-RADS) guidelines are aimed at providing a system for consistent reports and risk stratification for ovarian lesions found on ultrasound. It provides key characteristics and findings for lesions, a lexicon of descriptors to communicate findings, and risk characterization and associated follow-up recommendation guidelines. However, the O-RADS guidelines have not been validated in North American institutions or amongst less experienced readers.
