Substantial interreader agreement for biopsy with reduction in biopsy rate: A multireader diagnostic performance study of ACR TI-RADS.

Purpose: To assess diagnostic performance of ACR TI-RADS in thyroid cancer detection and evaluate interobserver agreement among radiologists with lower interpreting experience.

Methods: Four radiologists retrospectively assessed 295 biopsied thyroid nodules from ultrasound studies performed between 2009 and 2019, blinded to histopathology. Diagnostic performance for cancer detection was determined individually, and interobserver agreement among four readers was evaluated with Fleiss kappa coefficient (ⱪ).

Recurrent Nasal-Type Extranodal Natural Killer/T-Cell Lymphoma with Meningeal Involvement.

Extranodal natural killer/T-cell lymphoma nasal type (NNKTL) is a type of non-Hodgkin's lymphoma that has been associated with Epstein-Barr virus (EBV). It has an aggressive behavior, known for predilection to metastasize to different organs. Central nervous system (CNS) spread from a primary location has been reported.

Adding value to imaging services: a survey of patient and referring physician preferences for direct radiologic reporting of results.

Purpose: To identify preferences of patients and referring physicians for direct patient communication and notification of radiologic study results.

Methods: An anonymous survey was conducted of patients undergoing outpatient radiologic imaging studies and their referring physicians. The voluntary surveys elicited responses regarding preferences on a 5-point Likert scale (Strongly disagree, disagree, neutral, agree and strongly agree), as well as indicated by responding yes or no to specific questions.

MD and DO: Differing Medical Degrees and the Associated Perceptions.

Purpose: To highlight perspectives about differing medical degrees and graduate medical education amongst current allopathic (MD) and osteopathic (DO) radiology residents.

Materials And Method: Two hundred sixty-eight radiology residents were interviewed using an approved Association of Program Coordinators in Radiology (APCR) survey designed to evaluate perceptions of allopathic and osteopathic radiology residents regarding type of medical degree and their career development. The surveys were kept anonymous with no identifiable information.

Secondary encephalocele in an adult leading to subdural empyema.

Brain abscesses are an uncommon but potentially fatal infection. They can spread directly from an adjacent source or hematogenously from a distant source. Encephaloceles represent a rare form of neural tube defects that can potentially be complicated by the development of meningitis or brain abscess.

The Use of FDG PET Parametric Imaging in the Diagnosis of Olivopontocerebellar Atrophy.

Olivopontocerebellar atrophy is a rare neurodegenerative syndrome associated with 2 distinct disorders: multiple system atrophy and spinocerebellar ataxia. We present a case involving a 66-year-old man with adult-onset progressing cerebellar signs reflective of a cerebellar syndrome with no significant family history and unremarkable genetic testing for spinocerebellar ataxia. This case was found to be most consistent with sporadic olivopontocerebellar atrophy, which falls under the multiple system atrophy category.

Congenital absence of the internal carotid artery with intercavernous anastomosis.

Congenitally absent internal carotid artery with intercavernous anastomosis is an exceedingly rare vascular anomaly. We report such a case in a 65-year-old man with chronic symptoms resembling sporadic transient ischemic attacks. While these patients are usually asymptomatic due to compensatory collateralization, they are at increased risk of aneurysm formation, and thus proper identification is important.

Neck-Tongue Syndrome: Viewpoints on Etiology in a Patient with Bilateral Symptoms.

Neck-Tongue Syndrome is a rare entity, and when it presents in the pediatric age group, it is usually due to osseous, ligamentous, or nervous anatomic variation. We present below a case involving a patient whose bilateral symptoms were intermittently present from the age of five to the age of twenty-one years and discuss this case in light of the present theories of the anatomic substrate underlying this syndrome.

Ultrasound to Detect Pressure-related Deep Tissue Injuries in Adults Admitted via the Emergency Department: A Prospective, Descriptive, Pilot Study.

Stage 4 pressure ulcers (PUs) start with tissue death at the level of the bone, also known as deep tissue injury (DTI). Studies have shown the appearance of DTI on the skin is delayed for several days after the original pressure-related injury to the deep soft tissues. Studies also suggest DTI can be seen using ultrasound (US) technology.

A Survey of Academic Radiology Department Chairs on Hiring Recent Graduates as New Attending Physicians.

Rationale And Objectives: To determine hiring preferences among academic radiology department chairs with emphasis on recent residency and fellowship graduates.

Materials And Methods: With the assistance of the Society of Chairs of Academic Radiology Departments (SCARD), an anonymous survey was distributed to academic radiology department chairs during the time period December 2014-March 2015, with additional reminder emails during the study period. Varied multiple choice questions were designed to gather information regarding program details; qualities most valued in new attending hires; level of difficulty recruiting subspecialty fellowship-trained radiologists; and the effect of the new ABR certification process on hiring practices.

Intranasal foreign body mimicking a fat-containing lesion.

We present a 21-month-old child with a foreign body (an intranasal almond) measuring fat attenuation on CT. To the best of our knowledge, this appearance has not been previously described and can be confused with other diagnoses resulting in inappropriate or delayed treatment.

Adult female with hematemesis-Dieulafoy lesion.

A 40-year-old healthy woman presented to the emergency department with a complaint of intermittent hematemesis, despite the absence of usual factors associated with upper gastrointestinal bleeding (ie, nonsteroidal anti-inflammatory drugs, alcoholism, etc). The patient was diagnosed with a Dieulafoy lesion. This is an uncommon finding, which clinicians must be familiar with and maintain in the differential diagnosis because the consequences of this disease process are grave.

A patient with multiple synchronous gliomas of distinctly different grades and correlative radiographic findings.

Background: Multiple gliomas represent approximately 2 to 5% of all high-grade gliomas which are categorized as multifocal or multicentric depending on the timing, location and pattern of spread. We present a patient with bi-hemispheric, noncontiguous, low- and high-grade gliomas proven by biopsy. She underwent surgical excision and radiotherapy, but unfortunately succumbed to her disease shortly thereafter.

Sacral intraspinal meningocele in a patient presenting with abdominal pain. Case report.

Sacral meningoceles are typically asymptomatic. When they are symptomatic, patients commonly present with signs and symptoms of nerve root compression and back pain. The authors report the case of a 10-year-old girl with an intraspinal sacral meningocele who presented initially only with severe right lower quadrant pain.
