Imaging of the Vagina: Spectrum of Disease with Emphasis on MRI Appearance.

Radiographics 2021 Jul 23:210018. Epub 2021 Jul 23.

From the Mallinckrodt Institute of Radiology (M.Z., A.S., M.I., M.N., C.L.S.) and Department of Obstetrics and Gynecology (V.S.R.), Washington University School of Medicine, 510 S Kingshighway Blvd, St Louis, MO 63110; Department of Radiology, Mayo Clinic Arizona, Scottsdale, Ariz (M.Y.); Department of Diagnostic Imaging and Interventional Radiology, Moffitt Cancer Center, Tampa, Fla (M.M.); and Department of Oncologic Sciences, University of South Florida College of Medicine, Tampa, Fla (M.M.).

The vagina is a median fibromuscular structure of the female reproductive system that extends from the vulva inferiorly to the uterine cervix superiorly. As most vaginal lesions are detected at gynecologic examination, imaging performed for nongynecologic indications can frequently cause concomitant vaginal pathologic conditions to be overlooked. The vagina is often underevaluated at routinely performed pelvic transvaginal US because of a narrow scan area and probe positioning. Read More

A Rare Case of Intrapulmonary Sequestration With Multiple Feeding Arteries and an Anomalous Pulmonary Vein Draining Into the Azygos Vein.

Cureus 2021 Jun 13;13(6):e15628. Epub 2021 Jun 13.

Internal Medicine, Interfaith Medical Center, New York, USA.

Pulmonary sequestration is an isolated mass of lung tissue that has no identifiable bronchial communication and that receives its blood supply from one or more anomalous systemic arteries. The feeding vessel is the aorta or its major vessels and venous drainage usually is to the pulmonary veins to the left atrium. We present a rare case of intralobar sequestration in a 65-year-old man with multiple feeding arteries from the aorta and partial anomalous venous return draining into the azygos vein. Read More

Misdiagnosis of asymptomatic intrathyroidal pyriform sinus fistula: a case report.

J Int Med Res 2021 Jul;49(7):3000605211031430

Department of Pathology, 12553Hebei Medical University, The Second Hospital of Hebei Medical University, Shijiazhuang City, Hebei Province, P. R. China.

Pyriform sinus fistula is uncommon and easily misdiagnosed. Most reported cases occur in children and are associated with either acute suppurative thyroiditis or deep neck infection. Asymptomatic pyriform sinus fistula is difficult to diagnose because it can manifest as an incidental thyroid nodule with highly suspicious malignant features on ultrasonography. Read More

Impact of healthcare services on thyroid cancer incidence among World Trade Center-exposed rescue and recovery workers.

Am J Ind Med 2021 Jul 18. Epub 2021 Jul 18.

Fire Department of the City of New York, Bureau of Health Services, Brooklyn, New York, USA.

Background: A recent study of World Trade Center (WTC)-exposed firefighters and emergency medical service workers demonstrated that elevated thyroid cancer incidence may be attributable to frequent medical testing, resulting in the identification of asymptomatic tumors. We expand on that study by comparing the incidence of thyroid cancer among three groups: WTC-exposed rescue/recovery workers enrolled in a New York State (NYS) WTC-medical monitoring and treatment program (MMTP); WTC-exposed rescue/recovery workers not enrolled in an MMTP (non-MMTP); and the NYS population.

Methods: Person-time began on 9/12/2001 or at enrollment in a WTC cohort and ended at death or on 12/31/2015. Read More

Role of Imaging in Renal Cell Carcinoma: A Multidisciplinary Perspective.

Radiographics 2021 Jul 16:200202. Epub 2021 Jul 16.

From the Department of Radiology, University of Alabama at Birmingham, 619 19th St S, JTN 452, Birmingham, AL 35249-6830 (A.M.A.E., A.J.G., A.D.S.); Department of Radiation Oncology (S.S.L.) and Department of Radiology (S.S.V.), University of Washington School of Medicine, Seattle, Wash; Department of Urology, UCLA Medical Center, Santa Monica, Calif (B.M.S.); Department of Urology, Cleveland Clinic Foundation, Cleveland, Ohio (M.E.D.F., R.A.); Division of Hematology/Oncology, Department of Internal Medicine, Loyola University Medical Center, Maywood, Ill (J.I.C.); Department of Radiation Oncology, Sunnybrook Health Science Centre, University of Toronto, Toronto, Ontario, Canada (A.V.L.); Division of Radiation Oncology, Peter MacCallum Cancer Centre, University of Melbourne, Parkville, Victoria, Australia (S.S.); and Department of Radiation Oncology, University of Freiburg, Freiburg, Germany (A.L.G.).

With the expansion in cross-sectional imaging over the past few decades, there has been an increase in the number of incidentally detected renal masses and an increase in the incidence of renal cell carcinomas (RCCs). The complete characterization of an indeterminate renal mass on CT or MR images is challenging, and the authors provide a critical review of the best imaging methods and essential, important, and optional reporting elements used to describe the indeterminate renal mass. While surgical staging remains the standard of care for RCC, the role of renal mass CT or MRI in staging RCC is reviewed, specifically with reference to areas that may be overlooked at imaging such as detection of invasion through the renal capsule or perirenal (Gerota) fascia.

PET/CT variants and pitfalls in prostate cancer: What you might see on PET and should never forget.

Semin Nucl Med 2021 Jul 12. Epub 2021 Jul 12.

Nuclear Medicine Unit, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy; Department of Experimental, Diagnostic and Specialty Medicine, Alma Mater Studiorum, University of Bologna, Italy.

2-deoxy-2-[F]fluorodeoxyglucose (FDG) positron emission tomography (PET) gained an impressive role in the diagnostic management of many oncological diseases, even though its use in imaging prostate cancer (PC) is limited to selected cases, mostly advanced stage of PC and selection for prostate specific antigen membrane (PSMA) radioligand therapy (RLT). In the past years, several PET tracers have been developed for both staging and restaging PC. The three most employed PET molecules in daily practice are [C] or [F]F-Choline, [F]F-Fluciclovine (Anti-1- amino-3-[18F]Fluorocyclobutane-1-Carboxylic Acid, also known as (Anti-[F]FACBC), [Ga]Ga-PSMA and recently FDA approved the first Fluorinated PSMA-based named [F]F-DCFPyl.

Department of General Surgery, University of Health Sciences, Kanuni Sultan Suleyman Training and Research Hospital, Istanbul, Turkey.

Background: The clinical significance of gastrointestinal wall thickening (GWT) on abdominal computed tomography (CT) is not certain, yet. Despite the need for clinical guidelines describing the importance and evaluation of GWT on a CT scan, there have been few studies evaluating these incidental imaging abnormalities. The aim of this study is to endoscopically evaluate certain etiologies that cause incidental GWT found on CT. Read More
