Multimodal Imaging Demonstrated a Case of Buccal Cancer Cardiac Metastases Treated With Immune Checkpoint Inhibitor Therapy.

A 35-year-old man with recurrent oral cancer underwent restaging FDG PET/CT imaging, which revealed neck lymph node metastasis and multiple distant metastases, including involvement of the right atrium, right ventricle, and pericardium. Doppler echocardiography and cardiac MRI confirmed the cardiac metastases while demonstrating preserved left ventricular systolic function. Follow-up FDG PET/CT imaging at 3 and 6 months after immune checkpoint inhibitor therapy, initiated due to high PD-L1 expression in the primary tumor, showed complete remission.

Clinical effects of dupilumab: A novel treatment for Kimura disease.

Background: Kimura disease (KD) is a rare chronic inflammatory disorder involving the Th2 pathway. Although medical treatment with steroids or other immunosuppressants is available, they may cause developmental issues in the pediatric population. Surgical intervention has also been suggested; however, it is associated with high recurrence rates.

Adverse Events of Everolimus in Patients with Tuberous Sclerosis Complex Treated for Renal Angiomyolipoma/Subependymal Giant Cell Astrocytoma.

Although regarded as a potentially efficient approach to address tuberous sclerosis complex (TSC)-associated complications, the adverse event profile of everolimus has not yet been fully elucidated. The present study aimed to clarify the adverse event spectrum in patients with TSC who are using everolimus for common indications, in comparison to those who do not use everolimus. We recruited patients with TSC who were followed up annually at TSC integrated clinics or referred for medical assistance.

Ultrasonography Facilitates the Diagnosis of Traumatic Iliopsoas Hemorrhage: A Report of Two Cases with Different Patterns.

We report two cases of traumatic iliopsoas hemorrhage, without hemoperitoneum, initially detected by ultrasound. Flexion hip contracture in the first case and incomplete femoral nerve palsy in the second case alerted the sonographer to the possibility of traumatic iliopsoas hemorrhage. The first case involved a 54-year-old man who complained of progressive right flank pain and difficulty in walking after falling to the ground.

Abdominal Ultrasound in the Detection of an Incidental Paraganglioma.

Paraganglioma is a tumor that originates from neuroendocrine cells of the sympathetic or parasympathetic systems. Patients may suffer from headaches, palpitations, diaphoresis, and hypertension due to catecholamine excess or symptoms from the mass effect of the tumor. In the absence of typical symptoms of catecholamine excess, the diagnosis of a nonfunctional paraganglioma is often delayed.

Effectiveness of Thermal Ablation for Aldosterone-Producing Adrenal Adenoma: A Systematic Review and Meta-Analysis of Clinical and Biochemical Parameters.

Purpose: To assess the effectiveness of thermal ablation for aldosterone-producing adrenal adenoma.

Materials And Methods: A systematic search of the PubMed and CINAHL databases was performed to identify studies of thermal ablation for adrenal adenomas. Random effects meta-analysis models were used to compare pre- and post-treatment values of the following outcomes: systolic blood pressure (SBP), diastolic blood pressure (DBP), use of antihypertensive medications, and biochemical parameters (plasma aldosterone levels, aldosterone-to-renin ratio, and potassium levels).

Purpose: This study sought to determine the association between twinkling artifacts on color Doppler ultrasound and different types of guidewires.

Materials And Methods: Twenty-two commonly used guidewires were classified into three groups according to decreasing diameter (Group 1, 0.035"; Group 2, 0.

Continuous low-dose everolimus shrinkage tuberous sclerosis complex-associated renal angiomyolipoma: a 48-month follow-up study.

Tuberous sclerosis complex (TSC) is a rare disease that causes multisystem benign neoplasm, induced by dysregulation of the mammalian target of the rapamycin pathway (mTOR). This study aimed to examine the effects of continuous low-dose everolimus, a potent and selective inhibitor of mTOR, on the treatment of TSC-associated renal angiomyolipoma (AML). Between July 2013 and August 2017, 11 patients with TSC-AML were enrolled for an everolimus therapy protocol.

Hepatic Portal Venous Gas: Review of Ultrasonographic Findings and the Use of the "Meteor Shower" Sign to Diagnose It.

Ultrasonography (US) is believed to be the most available method of detecting hepatic portal venous gas (HPVG) with real-time imaging capability. Hepatic portal venous gas has characteristic image appearances in various ultrasound modes such as bright mode, Doppler mode, and even motion (M) mode. In this article, we give a comprehensive review of the image appearances of HPVG among different modes of US with a special focus on the M mode US.

CHA DS -VASc scores for outcome prediction in acute ischaemic stroke.

Background: The CHADS and CHA DS -VASc scores are clinical risk stratification instruments that are used clinically to assess the risk of stroke in patients with atrial fibrillation (AF). The aim of this study was to evaluate whether the prestroke CHADS and CHA DS -VASc scores could be useful for predicting infarction severity and long-term outcomes in patients with acute ischaemic stroke.

Materials And Methods: This prospective study included all 1494 patients who had acute ischaemic stroke without haemorrhagic transformation which was evidenced with magnetic resonance (MR) imaging during hospitalization.

Prostatic Arterial Embolization for Control of Hematuria in Patients with Advanced Prostate Cancer.

Nine patients with advanced prostate cancer (stage T4) underwent prostatic arterial embolization (PAE) for refractory prostatic hematuria. Angiograms showed prostatic neovascularity in all cases, and complete PAE was achieved in 8 cases (89% technical success rate). Gross hematuria ceased after PAE in 6 cases, translating to a 67% clinical success rate.

The Performance of Noncontrast Magnetic Resonance Angiography in Detecting Renal Artery Stenosis as Compared With Contrast Enhanced Magnetic Resonance Angiography Using Conventional Angiography as a Reference.

Objective: The aims of this study were to evaluate the performance of noncontrast magnetic resonance angiography (NC MRA) for detecting renal artery stenosis (RAS) as compared with contrast-enhanced magnetic resonance angiography (CE MRA) and to evaluate the clinical feasibility, technical success rate, and performance of NC MRA for detecting RAS as compared with CE MRA.

Methods: Thirty-six subjects who underwent NC MRA and/or CE MRA were enrolled. Feasibility, technical success rate, and image quality scores were compared.

Diagnostic Performance of Combined Contrast-Enhanced Magnetic Resonance Angiography and Phase-Contrast Magnetic Resonance Imaging in Suspected Subclavian Steal Syndrome.

Purpose: The study sought to evaluate the efficacy of magnetic resonance imaging (MRI) in patients with suspected subclavian steal syndrome (SSS) using both contrast-enhanced (CE) MR angiography and phase-contrast (PC) MRI.

Methods: Fifteen suspected SSSs from 13 patients were evaluated using CE-MR angiography and PC-MRI. Ten patients also received dynamic CE-MR angiography.

Association between the growth rate of subependymal giant cell astrocytoma and age in patients with tuberous sclerosis complex.

Purpose: The most common neurological complications associated with tuberous sclerosis complex (TSC) include intractable seizures that begin in infancy and subependymal giant cell astrocytoma (SEGA) complicated by hydrocephalus with increasing age. Information on SEGA growth of TSC patients is limited. This study aimed to examine the TSC-SEGA growth rates by periodic neuroimaging.

Extra-adrenal paraganglioma presenting as acute chest pain mimicking acute myocardial infarction in a 10-year-old boy.

Extraadrenal paragangliomas are rare pediatric tumors with variable symptoms that cause difficultly in diagnosis and delayed treatment. We report the case of a 10-year-old boy who presented to the pediatric emergency department with acute chest pain and dyspnea mimicking a non-ST-segment elevation acute myocardial infarction. He was subsequently found to have an extraadrenal paraganglioma after a series of imaging and laboratory examinations.

Image quality improvement in three-dimensional time-of-flight magnetic resonance angiography using the subtraction method for brain and temporal bone diseases.

Background: Time-of-flight (TOF) magnetic resonance (MR) angiography is based on flow-related enhancement using the T1-weighted spoiled gradient echo, or the fast low-angle shot gradient echo sequence. However, materials with short T1 relaxation times may show hyperintensity signals and contaminate the TOF images. The objective of our study was to determine whether subtraction three-dimensional (3D) TOF MR angiography improves image quality in brain and temporal bone diseases with unwanted contaminations with short T1 relaxation times.

Normal uricemia in Lesch-Nyhan syndrome and the association with pulmonary embolism in a young child-a case report and literature review.

Deficiency of hypoxanthine phosphoribosyltransferase activity is a rare inborn error of purine metabolism with subsequent uric acid overproduction and neurologic presentations. The diagnosis of Lesch-Nyhan syndrome (LNS) is frequently delayed until self-mutilation becomes evident. We report the case of a boy aged 1 year and 10 months who was diagnosed with profound global developmental delay, persistent chorea, and compulsive self-mutilation since the age of 1 year.
