ABSTRACT Male breast cancer is rare, representing less than 1% of breast cancer cases, and is often diagnosed at a later stage due to a low index of clinical suspicion. This is the case of an invasive ductal carcinoma in a middle-aged man with a history of cardiac transplantation and long-term immunosuppressant use. The patient presented with a breast lump found on self-examination, which was then evaluated with diagnostic mammography and US. Imaging demonstrated a suspicious retroareolar mass with associated nipple retraction, and subsequent US-guided core biopsy confirmed moderately differentiated invasive ductal carcinoma (ER-positive, PR-positive, HER2-negative). This case highlights the importance of maintaining clinical suspicion for breast malignancy in male patients presenting with a new breast mass, even in the absence of traditional risk factors such as family history of breast cancer. Thorough clinical evaluation and appropriate diagnostic imaging can facilitate early detection and treatment of male breast cancer.

Abstract Cystic and cyst-like lesions of the mediastinum encompass a broad spectrum of entities ranging from benign congenital abnormalities to inflammatory or malignant processes with cystic components. These lesions are frequently encountered with cross-sectional imaging and may present a diagnostic challenge due to overlapping imaging appearances. Accurate characterization is critical, as misclassification can lead to unnecessary surgical intervention or delayed diagnosis of clinically significant disease. These lesions can be incidentally identified on routine chest radiographs as paramediastinal opacities. CT is typically the initial imaging modality for further evaluation of mediastinal lesions and provides essential information regarding lesion location, morphology, and relationship to adjacent structures. MRI offers superior soft-tissue characterization and plays a key role in problem-solving, particularly when CT findings are indeterminate. The use of T1- and T2-weighted sequences, along with diffusion-weighted imaging, facilitates differentiation of simple cysts from lesions containing solid, proteinaceous, or malignant components. Awareness of characteristic imaging features of common congenital cysts, acquired cystic lesions, and important mimics further improves diagnostic confidence. In conclusion, mediastinal cystic lesions require a structured imaging-based approach for accurate diagnosis. Integration of clinical context, anatomic location, and multimodality imaging findings, with particular emphasis on MRI, supports appropriate risk stratification and individualized patient management.

Remote interpretation is well established in screening mammography, helping health systems achieve timely reads and provide patient access to specialty expertise.As the radiologist shortage persists amid increasing breast imaging volumes, many systems now use a remote model for diagnostic reads, which presents new opportunities and challenges."Several factors are driving the growth of remote breast imaging, one of the biggest being the nationwide shortage of breast imaging radiologists," says Rajshri N. Shah, MD, Medical Director of Breast Imaging, Radiology Care Division at Prisma Health, Greenville, South Carolina."At the same time, demand for services continues to increase as screening programs expand, awareness improves, and more women undergo supplemental and high-risk screening."Diagnostic interpretations require more than quality image transmission; they demand continuity for timely clinical decision-making.As practices face the workflow, staffing, and technology complexities of maintaining this continuity, market forces continue to shift in support of this growing remote model."Remote diagnostic mammography is being driven by the convergence of several needs," Dr Shah says, "addressing workforce shortages, improving access to specialized breast imaging expertise, supporting radiologist well-being, and ensuring that patients continue to receive timely, high-quality care."

Abstract The field of radiology is always changing, particularly with respect to image-guided breast cancer cryoablation. While this therapy has been studied for decades, the results of recent clinical trials have made the concept of treating breast cancer without surgery closer to reality. The technique closely resembles that of percutaneous image-guided breast biopsy, and the skill set to perform this procedure can be acquired by breast and interventional radiologists. Small, low-risk breast cancers can be treated with cryoablation, and there is an opportunity to use it for palliative care. Potential immune benefits of cryoablation add to the appeal and interest in this procedure.

Abstract E-cigarette or vaping product use-associated lung injury is a serious and potentially life-threatening respiratory condition characterized by diffuse lung injury following recent use of vaping or e-cigarette products. Patients commonly present with nonspecific respiratory symptoms such as cough, chest pain, and dyspnea, along with constitutional symptoms, including fever, chills, fatigue, weakness, and malaise. A small number of pediatric patients may present with isolated gastrointestinal symptoms. Noncontrast chest CT is the preferred imaging modality and may show a range of findings consistent with diffuse lung injury. Treatment is primarily supportive and may include supplemental oxygen, empiric antibiotics, and systemic glucocorticoids based on clinical presentation.

Abstract Diastematomyelia is a rare congenital malformation, accounting for approximately 5% of all congenital spinal anomalies. It is characterized by a longitudinal split of the spinal cord into 2 hemicords and often presents alongside other neural tube defects. Diastematomyelia is classified into 2 types: type 1, which involves a bony or cartilaginous septum separating the hemicords, and type 2, where no septum is present. Clinical manifestations include hypertrichosis, back pain, lower limb motor and sensory deficits, foot deformities, and scoliosis, though some patients may remain asymptomatic. Diagnosis is typically made with CT or MRI. Surgical correction is the standard treatment, even in asymptomatic patients, to prevent future neurological decline.

Abstract Migraine headaches can significantly impact both the physical and psychological well-being of children and adolescents, and have been shown to have a considerable prevalence within this population. It is therefore reasonable to further explore treatment modalities that can alleviate or resolve migraine symptoms. Sphenopalatine ganglion block represents one of these modalities and has demonstrated promising and successful outcomes when treating migraines in the pediatric population.
