Extraskeletal osteosarcoma are rare malignant mesenchymal neoplasms of soft tissues representing around 1% of all soft tissue. The exact mechanism of tumorigenesis of primary breast osteosarcoma is still unclear. However, most of the cases develop without a recognized etiologic factor. Primary osteosarcoma of the breast is often initially misdiagnosed as breast fibroadenoma. Different imaging modalities and pathology play important role in differentiating breast osteosarcoma from other benign and malignant lesions of the breast resulting in dramatic change in the management...

Ewing sarcoma (ES) and peripheral primitive neuroectodermal tumor are part of a spectrum of neoplastic diseases known as the ES family of tumors, which also includes extraosseous ES, peripheral primitive neuroectodermal tumor, malignant small-cell tumor of the thoracopulmonary region (Askin's tumor), and atypical ES. Although imaging features of these tumors have been previously described, extensive discussion about intra-abdominal manifestations is scarce in the literature. We present an imaging spectrum of these tumors in the abdomen and pelvis with particular attention to multimodality approach for staging and restaging...

There is an enduring dilemma on the appropriate management of high-risk breast lesions; is surgical excision always warranted or can conservative management be utilized? We present cases of high-risk breast lesions diagnosed at core needle biopsy at our institution along with relevant factors to consider for appropriate management. We conclude that a nuanced approach is warranted over the broad stroke approach of surgical excision of all high-risk breast lesions.

The socioeconomic dynamics of the current healthcare system can challenge physicians to remain engaged with meaningful work, which is problematic given its role in mitigating burnout. In Man's Search For Meaning, Victor Frankl proposes that meaningful work is a prerequisite for a meaningful life. This article provides a road map for radiologists by applying key guiding principles outlined by Frankl as they intersect with current evidence in the field of physician burnout.

Radiologists experience higher than average rates of burnout. Contributing factors include job tedium, a lack of a sense of autonomy, and decreasing compensation in the context of practices closely monitoring relative value unit output. Increasing radiologist efficiency may be a strategy for mitigating burnout, as freeing up time may allow radiologists to focus their attention on the aspects of their job that they enjoy and find most meaningful. In this work we propose several strategies of distraction minimization and time optimization that radiologists may employ to increase their efficiency...

Airway Injuries are rare but often immediately life threatening. Incidence ranges from 0.5-2 % in blunt and 1-6 % in penetrating trauma. Upper airway injuries (UAI) are often clinically apparent and get shunted during the primary survey in the emergency department. Few UAI and majority of lower airway injuries (LAI) are occult on primary survey and need a high suspicion index. Clinically, the diagnosis of tracheobronchial injury is delayed in many patients because the airway column is maintained by the peribronchial tissue...

Adrenal tumors are very commonly encountered in the practice of radiology. They may arise from the adrenal gland itself, either the cortex or the medulla, or they could be secondary lesions. They may be benign or malignant. The functioning adrenal tumors lead to hypersecretion of adrenal hormones leading to clinical syndromes. Computed tomography is the most common imaging modality used for the initial evaluation of adrenal tumors. Magnetic resonance imaging and functional scintigraphic techniques are frequently used for atypical presentations or further evaluation...

The Medicare Access and CHIP Reauthorization Act of 2015 was signed into law on April 16, 2015, fundamentally altering the way clinicians are reimbursed for the treatment of Medicare patients starting in 2017. Under this new pay-for-performance model, reimbursement will be tied to multiple metrics related to quality and cost of care. A scaled scoring system will require providers to compete for positive reimbursement adjustments, while also penalizing poor performers with negative adjustments. A firm understanding of this new system will be essential for all physicians looking to maximize their reimbursement, particularly diagnostic radiologists and members of other highly focused fields where special considerations lead to alterations in the scoring system...
