Infantile myofibromatosis is a rare disorder of mesenchymal cell proliferation that can affect the skin, bone, muscle, and viscera. We present a case of a 6-week-old male with a rapidly enlarging congenital solitary infantile myofibroma. The differential for congenital tumors of the head and neck is broad, and thorough evaluation is required to rule out life-threatening malignancy. Currently, there is no first-line imaging modality of choice to assess for skeletal and/or visceral involvement in patients with infantile myofibromatosis. We recommend the use of whole-body magnetic resonance imaging (MRI), as it quickly provides detailed information regarding extent of disease and does not expose the patient to the harmful effects of radiation.

AbstractTendon injuries represent the second most common injury of the hand (after fractures) and are a common scanning indication in radiology. Pulley injuries are very frequent in rock climbers with the A2 pulley the most commonly affected. Tendon and pulley injuries can be reliably evaluated using ultrasound (US) and magnetic resonance imaging (MRI). US can be postulated as a first-line imaging modality, allowing dynamic examination. MRI is essential for cases with ongoing diagnostic doubt post-US and also for preoperative pulley reconstruction assessment.

Proptosis in the neonatal period is relatively infrequent and has diverse underlying etiologies. One of the more common causes appears to be orbital subperiosteal hematoma. Early detection, differentiation from other causes, and regular follow-up are essential as loss of vision can occur. We describe two cases of neonatal proptosis caused by orbital subperiosteal hematoma highlighting different diagnostic and management approaches, and provide a summary of previously reported cases. Spontaneous resolution occurs in most cases; however, emergent surgical evacuation is warranted in cases of optic nerve compression. This is the first report to provide orbital ultrasound images of uncomplicated neonatal orbital subperiosteal hematoma. Orbital ultrasound followed by magnetic resonance imaging (MRI) is a valid nonradiation approach for assessing neonatal proptosis due to subperiosteal orbital hematoma.

AbstractPediatric patients often present to the emergency department with a wide variety of infectious, inflammatory, and neoplastic lesions of the head and neck. Evaluation of pediatric patients in the emergency setting is complicated by limited history and physical examination. Imaging plays an important role in arriving at an accurate diagnosis. The fascial spaces and compartments of the neck provide an approach to differential diagnosis, and knowledge of the typical clinical and imaging manifestations of common pediatric head and neck emergencies allows the radiologist to identify the condition and associated complications that may require emergent surgical management. Computed tomography (CT) is the first-line imaging modality in the emergency setting; however, magnetic resonance imaging (MRI) plays an important secondary role.

Sedation can induce atelectasis which may cause suboptimal image quality. This study aimed to identify factors associated with the occurrence of atelectasis during sedation for imaging in pediatric patients. Patients < 18 years who had undergone whole-body magnetic resonance imaging (MRI) under sedation with propofol or dexmedetomidine were included in this study. The development of atelectasis was visually and quantitatively assessed by coronal short tau inversion recovery images of the thoracic level. Multivariable logistic regression was performed to identify the independent factors associated with the development of atelectasis. Ninety-one patients were included in the analysis. In the multivariable analysis, administration of supplemental oxygen was the only factor significantly associated with the occurrence of atelectasis (adjusted odds ratio, 4.84; 95% confidence interval, 1.48–15.83; p = 0.009). Univariable analysis showed that the use of dexmedetomidine was associated with a lower incidence of atelectasis; however, this could not be verified in the multivariable analysis. Among the pediatric patients who had undergone imaging under sedation, additional oxygen supplementation was the only independent factor associated with atelectasis occurrence. A prospective clinical trial is required to identify the cause-effect relationship between oxygen administration and occurrence of atelectasis during sedation.

Background Magnetic resonance imaging (MRI) is the first-line imaging modality for local staging of rectal cancer. The radiology report should deliver all relevant available imaging information to guide treatment. Purpose To explore and describe if there was a gap between the contents in MRI reports for primary staging of rectal cancer in Sweden in 2010 compared to evidence-based practice. Material and Methods A total of 243 primary MRI staging reports from 2010, collected from 10 hospitals in four healthcare regions in Sweden, were analyzed using content analysis with a deductive thematic coding scheme based on evidence-based practice. Focus was on: (i) most frequently reported findings; (ii) correlation to key prognostic findings; and (iii) identifying if any findings being reported were beyond the information defined in evidence-based practice. Results Most frequently reported findings were spread through the bowel wall or not, local lymph node description, tumor length, and distance of tumor from anal verge. These items accounted for 35% of the reporting content. Of all reported content, 86% correlated with the evidence-based practice. However, these included more information than was generally found in the reports. When adjusting for omitted information, 48% of the reported content were accounted for. Of the reported content, 20% correlated to key pathological prognostic findings. Six types of findings were reported beyond the evidence-based practice, representing 14% of the total reporting content. Conclusion There was a gap between everyday practice and evidence-based practice in 2010. This indicates a need for national harmonization and implementation of standardized structured reporting templates.

AbstractHip arthroplasty is a common and largely successful surgical procedure, often used for the treatment of advanced osteoarthritis. Imaging plays a key role in routine postoperative imaging surveillance as well as the evaluation of post-arthroplasty pain. Radiographs are the first-line imaging modality and may be followed by computed tomography (CT), ultrasound, and/or magnetic resonance imaging (MRI). Recent advancements in imaging techniques allow for metal artifact reduction on CT and MRI. A variety of complications can arise in the setting of arthroplasty: mechanical loosening, component wear-induced synovitis and osteolysis, adverse local tissue reaction, infection, periprosthetic fracture, implant dislocation and/or component displacement, tendinopathy, and neurovascular injury. This article reviews normal and abnormal imaging findings of hip arthroplasty.
