Incidental Finding Of Anomalous Pulmonary Venous Return Of The Left Upper Lobe, A Rare Anatomical Variation, 2021 Chicago Medical School
Incidental Finding Of Anomalous Pulmonary Venous Return Of The Left Upper Lobe, A Rare Anatomical Variation, Anika Dutta, Loren Zuiderveld
Journal of Patient-Centered Research and Reviews
Partial anomalous pulmonary venous return (PAPVR) is a rare congenital abnormality in which 1 to 3 of the pulmonary veins connect to the right atrium rather than the left atrium. In this synthesis of the literature on PAPVR of the left upper lobe, we attempt to illustrate this clinical entity using a case detected incidentally on chest computed tomography, explain the anatomical aspects of this anomaly, and summarize the reported incidence and etiology of left-sided PAPVR. Lastly, differential diagnoses, clinical relevance, and management of left-sided PAPVR are presented. The identification of this variant is important, as it may have serious ...

The most common cause of skin metastases in adult women is primary breast carcinoma, which comprises about 70% of cases . Skin metastases have non-specific clinical appearances, making it challenging to differentiate them from other benign conditions . We present a case of a 52-year-old female with type II diabetes and a three-month history of refractory skin lesions who did not respond to anti-inflammatory treatment. The patient subsequently complained of a right breast lump, evaluation of which led to the diagnosis of bilateral synchronous invasive lobular carcinoma.

Recent advances in deep-learning technology have brought revolutionary changes to artificial intelligence (AI) research and application across industries, yielding major innovations such as facial recognition and self-driving cars. Medicine is no exception, and radiology, which is based on the interpretation of image data obtained through various methods-and has often been compared with computer vision using pattern analysis-is anticipated to experience a major revolution. Despite expectations for increasing research and development of AI-empowered ultrasonography, the clinical implementation of AI in medical ultrasonography faces unique obstacles. It will be necessary to standardize image acquisition, regulate operator and interpreter qualification and performance, integrate ...
Colonic Migration Of A Nephroureteral Stent Through A Colovesical Fistula, 2021 Aventura Hospital and Medical Center
Colonic Migration Of A Nephroureteral Stent Through A Colovesical Fistula, Nicholas Pigg, Kevin Carr, Julio Zayas, Eduardo Franca
HCA Healthcare Journal of Medicine
We describe a case of a patient with a two-year history of prostate cancer who underwent placement of nephroureteral stents. He subsequently presented to the hospital with complications from prolonged retention of the stents, which ultimately lead to a secondary diagnosis of adenocarcinoma of the rectum. A colonoscopy performed approximately two weeks after a bilateral nephroureteral tube exchange demonstrated what was believed to be locoregional metastatic disease and a fistulous connection with the distal nephroureteral stents. Radiographic features of this complication are discussed together with proper management and possible complications of distal nephroureteral stents. Both nephroureteral stents were explanted, and ...

Extrapulmonary Tuberculosis: A Case Report Involving The Spine And Soft Tissues, Aden Gunnar Miller, Paul J. Spicer
Radiology Faculty Publications
Tuberculosis (TB) is a major health concern worldwide, and its incidence is increasing in developed countries, especially among immigrant populations. Extrapulmonary TB with musculoskeletal involvement is often a difficult and delayed diagnosis, as the disease can mimic metastases or infection. We present a case of extrapulmonary TB affecting the spine and soft tissues of a Vietnamese-born patient living in the United States. We discuss the imaging findings associated with extrapulmonary TB of the spine. Familiarity with key imaging features of disease can lead to early suspicion and detection of the disease as well as timely treatment.

A Case Of Distal Limb Arterial Tortuosity And Dilation: Observations And Potential Clinical Significance, Yasmin Carter, Desmond J. Bennett, Vadim Molla, Alexandra E. Wink, Amanda J. Collins, Eustathia Lela Giannaris
Arterial tortuosity describes variation via bending of the arterial wall and has been noted in several arteries throughout the body. Tortuous blood vessels can cause nerve compression, as well as present difficulties to surgeons and radiologists. Here we present an unusual case of multi-vessel arterial tortuosity discovered in 78-year-old Hispanic male cadaver, independent of systemic pathology. The left ulnar and right tibial arteries were dissected, and using calibrated digital calipers, their external and internal diameters were measured both at the origin site and at the site of greatest dilation. Both wall thickness and the number of inflection points were also ...

Lack Of Progression Of Intraventricular Hemorrhage In Premature Infants: Implications For Head Ultrasound Screening, 2021 University of Massachusetts Medical School
Lack Of Progression Of Intraventricular Hemorrhage In Premature Infants: Implications For Head Ultrasound Screening, Jaclyn Daigneault, Heather White, Alexandra Dube, Qiming Shi, Jean-Marc Gauguet, Lawrence M. Rhein
Very preterm infants are at risk for germinal matrix hemorrhage- intraventricular hemorrhage (GH-IVH). Severe GH-IVH may cause death or severe neurodevelopmental disability while mild GH-IVH is considered a static, non-progressive disease. This retrospective study aimed to determine if infants with no GH-IVH or mild GH-IVH on initial screening head ultrasound (HUS) advanced to severe GH-IVH. A total of 353 eligible infants with birth gestational age < /=32 0/7 weeks who received a HUS during hospitalization were identified. Of the 343 (97%) infants who had mild GH-IVH (grade II or less) on initial screening, only 4 (1.2%) progressed to severe (grade III or IV). Each of these infants required mechanical ventilation for at least 40 days. Therefore, premature infants who have no GH-IVH or mild GH-IVH on initial routine screening HUS without other risk factors may not require follow-up HUSs. Infants with prolonged mechanical ventilation may require further screening despite reassuring initial HUS findings.

BACKGROUND: Emergent large vessel occlusion (ELVO) strokes are devastating ischemic vascular events for which novel treatment options are needed. Using vascular cell adhesion molecule 1 (VCAM1) as a prototype, the objective of this study was to identify proteomic biomarkers and network signaling functions that are potential therapeutic targets for adjuvant treatment for mechanical thrombectomy.
METHODS: The blood and clot thrombectomy and collaboration (BACTRAC) study is a continually enrolling tissue bank and registry from stroke patients undergoing mechanical thrombectomy. Plasma proteins from intracranial (distal to clot) and systemic arterial blood (carotid) were analyzed by Olink Proteomics for N=42 subjects. Statistical ...
Guided Imagery And Sentinel Lymph Node Biopsy Pain, 2021 Valparaiso University
Guided Imagery And Sentinel Lymph Node Biopsy Pain, Brandy Alicia Kirk
Evidence-Based Practice Project Reports
The standard of care in the treatment for women diagnosed with breast cancer includes identification and biopsy of the sentinel lymph nodes (SLN) of the breast (Chaterjee et al., 2017; Kneece, 2017). The process of identifying the SLNs involves radioisotope injections into or near the areola. Because this area is highly sensitive, women report this procedure to be considerably painful. The purpose of this evidence-based practice (EBP) project was to determine if the provision of a 5-minute session of guided imagery (GI), as a complementary alternative medicine, prior to SLN injections was effective in mitigating reports of procedural pain. A ...

Modest expansion of the human brain cerebrospinal fluid (CSF)-filled ventricles is normal with aging, and because of this, it can be difficult for physicians to accurately diagnose and treat enlarged ventricles (ventriculomegaly), called hydrocephalus1 (fluid or water in the brain) Ventriculomegaly occurs due to an obstruction (such as a blood clot or tumor), or a change in CSF absorption2. Primary hydrocephalus, also called idiopathic normal pressure hydrocephalus (iNPH), is non-obstructive and may be comorbid with other neurodegenerative diseases such as Alzheimer’s disease (AD) or frontotemporal dementia (FTD). Clinically, it can be difficult to tell whether the ...

The overall aggressiveness of a glioma is measured by histologic and molecular analysis of tissue samples. However, the well-known spatial heterogeneity in gliomas limits the ability for clinicians to use that information to make spatially specific treatment decisions. Magnetic resonance imaging (MRI) visualizes and assesses the tumor. But, the exact degree to which MRI correlates with the actual underlying tissue characteristics is not known.
In this work, we derive quantitative relationships between imaging and underlying pathology. These relations increase the value of MRI by allowing it to be a better surrogate for underlying pathology and they allow evaluation of the ...
