In radiology, scoring-based peer review is the dominant model focused on quality assurance, rather than quality improvement. Although designed to decrease diagnostic errors in radiology, this model has had an overall negative effect secondary to its punitive nature and lack of educational benefit. A peer learning-based system helps circumvent these issues through a multitude of ways. These include increasing learning opportunities, identifying system errors that maybe contributing to the misdiagnosis, and fostering a “just” environment where constructive feedback is given to the radiologist. By changing to the peer learning paradigm, this helps increase engagement and satisfaction by participating radiologists to improve patient care.

The knee joint is the largest joint in the body and comprises the tibiofemoral (medial and lateral) and the patellofemoral compartments. The knee joint is a modified hinge joint and relies on several associated muscles, tendons, and ligaments to provide strength and stability during movement and at rest. A limping child with a swollen knee is a common presentation encountered by pediatricians. Although trauma is the most common cause of pediatric knee swelling, a wide variety of pathologies can manifest as a swollen and/or painful knee joint in children, reflecting underlying abnormalities of soft tissue or osseous components of the knee.1,2 In the absence of a recent or remote history of knee trauma, other pathologic causes of knee swelling include infections and inflammatory conditions, congenital/developmental causes, vascular abnormalities, and neoplastic disorders.

Diagnosis of acute pulmonary embolism (PE) can be challenging for both clinicians and radiologists. CT angiography (CTA) has emerged as the most practical imaging modality to ensure accurate and prompt recognition of acute PEs. Thus, radiologists are positioned as the first physicians able to confirm a diagnosis of acute PE in clinically suspected cases. However, in addition to identifying acute PE on CTA, radiologists also must be aware of its mimics. Misdiagnosis of PE can result in detrimental patient outcomes, exposing patients unnecessarily to the risks of anticoagulation and delaying recognition of any true underlying pathology. In this article, we discuss entities that can be mistaken for acute PE on CTA. These mimics include artifacts, nonvascular abnormalities, and various causes of filling defects in the pulmonary vasculature, both thrombotic and nonthrombotic. The objectives of this article are to familiarize the reader with mimics of acute PE and to review the characteristic features that differentiate them from acute PE on CT.

Lung cancer continues to be a pervasive disease. It is the second most common cancer behind prostate cancer in men and breast cancer in women.1 There were an estimated 229,000 new cases of lung cancer diagnosed in the United States and an estimated 136,000 deaths from lung cancer in 2020.1 The high mortality of lung cancer is partly explained by its tendency to be asymptomatic in early stages, which makes it much more likely to be first diagnosed at more advanced stages when treatment options are much less effective.2 Once diagnosed, it is essential that the patient and physician quickly decide on the best treatment course.

Connective tissue diseases (CTDs) form a group of chronic inflammatory disorders characterized by disturbance in immune mechanisms and defective clearance of apoptotic and immune complexes. Virtually all cells and tissues containing collagen or elastin are affected, resulting in multisystemic derangements and significant morbidity and mortality. Clinical manifestations are nonspecific and may not occur simultaneously, predisposing to a delayed or missed diagnosis. Imaging aids in supporting the diagnosis when diagnostic criteria are not met, determining extent and severity of disease, and monitoring treatment response and complications.

Neck sonography is well-established as a primary imaging tool for the evaluation of the thyroid gland and thyroid-related pathologies. However, there are other structures within the head and neck that may be thoroughly evaluated sonographically, avoiding the need for more costly and time-consuming imaging modalities. The authors seek to tout the prowess of ultrasound beyond the typical confines of the thyroid, focusing on the sonography of the floor of the mouth.

Gas in the musculoskeletal system is frequently encountered in clinical practice and can indicate either a benign or nefarious process. Anaerobic infection is capable of producing gas in the musculoskeletal system; however, nonaggressive processes accounting for gas are much more common. In some instances, the presence of gas can be used to exclude a diagnosis of infection. Nitrogen gas bubble may be formed with joint manipulation,1–3 in volume loss and degeneration,4 and in traumatic dislocation/diastasis. The presence of gas with fracture is consistent with open fractures, which affect clinical management, and is associated with future complications.5 The referring or treating physician may also introduce gas through arthrocentesis, injection, or surgery. However, infection must always be considered with scrutiny of the radiologic records and correlation with the clinical history and physical examination so that proper treatment is not delayed. Therefore, it is important for the radiologist to recognize the presence of gas on imaging studies and have the expertise to appropriately raise clinical suspicion of infection or assign a typically benign cause to avoid unnecessary diagnostic evaluation and therapeutic procedures.

In this second article in this series, we present a pictorial review of common renal neoplasms and renal malignancy mimics, including urothelial carcinoma, liposarcoma, oncocytoma, renal pseudotumors, and renal metastases. Renal cell carcinoma (RCC) subtypes and their respective radiologic findings were discussed in Part I of this series. Principles of management of select RCC subtypes and other renal neoplasms, including urothelial carcinoma and angiomyolipoma (AML), will be discussed. Management of solitary renal masses via active surveillance (AS) or surgical intervention and the indications for renal mass biopsy as part of the diagnostic workup will also be reviewed.

Renal cell carcinoma (RCC) accounts for approximately 3% of all adult malignancies, with clear cell subtype representing the majority of these cases. In the United States, the number of new cases of kidney and renal pelvis cancers was 15.6 per 100,000 men and women per year. Although the incidence of RCC has been increasing for several years, the landscape of RCC has changed significantly due to the use of highly sensitive imaging modalities. The percentage of early-stage T1 Kidney cancers has increased from 43% to more than 60% over the past two decades, with a 5-year survival rate of more than 90% for these early-stage tumors.1 As diagnostic imaging plays a significant role in the detection and management of these cancers, a fundamental understanding of RCC and its various subtypes is essential for all medical imaging specialists.

Fluoroscopy is a key imaging modality in the pediatric population and can be used to diagnose emergent conditions in the neonatal period, including malrotation with midgut volvulus, and atresias of the small intestine. This activity is designed to teach radiologists about critical portions of the pediatric upper gastrointestinal fluoroscopic examination and to provide an overview of pediatric upper gastrointestinal fluoroscopy for general practitioners to improve confidence and accuracy with diagnosing common and emergent conditions.
