Peer review is an essential component of quality improvement in radiology departments. Over the last years, several papers described a shift towards peer learning, emphasizing that feedback in the form of comments and peer learning conferences creates a more productive environment for reviewing and understanding perceptual or interpretive errors of peer radiologists, with improved diagnostic performance as the objective. At our institution, we instituted a three-month scoreless peer review pilot period. Radiologists’ impressions regarding the current comment-enhanced numerical system and the pilot scoreless, comments-only period were collected through an online survey. Read More

Ovarian torsion in pediatrics is challenging to diagnose, both clinically and radiologically. Ultrasound is most commonly used to evaluate for this process, though there are no sonographic findings that are pathognomonic. One sonographic finding that has been infrequently reported in the literature is medialization of the ovary (defined as the ovary at or crossing the midline of the uterus), as the adnexal structures are drawn inwards by the twisted broad ligament. Knowledge of this finding in addition to the other more classic findings of torsion can be an important clue to the diagnosis. This study evaluates the presence of ovarian medialization in a large number of cases of known torsion. Read More

Purpose Ovarian torsion is rare in neonates and infants. Clinical diagnosis is challenging in the setting of lack of specific symptoms and the limitations in assessing pain in infants. Torsed ovaries in this patient population are also a diagnostic dilemma on imaging. In this study we reviewed the spectrum of imaging findings with pathologic correlation in a large series of patients. Read More

Pelvic ultrasound is commonly used to detect ovarian torsion, but the diagnosis remains challenging as there is no single pathognomonic feature. This retrospective case-controlled study aims to identify an algorithm to detect torsion based on common ultrasound imaging features. Read More

The general pediatric radiologist is well aware of the classic scintigraphic findings of common malignancies. However, atypical presentations, appearances, and complications related to treatment and resultant immunosuppression may confound diagnosis. We present a series of interesting cases to help our non-nuclear medicine trained colleagues develop a systematic approach to nuclear medicine image interpretation in atypical cases. Read More

Ultrasound has long been a readily available, noninvasive, and accurate means of evaluating the female pelvis and is widely used in the emergency setting for girls with abdominal and pelvic pain. One key element in evaluating for pathology is to measure ovarian size and compare left and right ovaries. Normative volume data stratified by age are available; however, these studies suffer from lack of numbers, and frequently older equipment. Technological advances in ultrasonic hardware and software have increased the resolution of both gray-scale and Doppler imaging. Increases in spatial resolution allow for better identification and measurement of ovaries and precise measurements and depictions of anatomic details. The purpose of this study was to re-evaluate normal pediatric ovarian volumes in relation to patient age with a larger dataset and newer technology. Read More

Ewing sarcoma is the second most common malignancy of bone with an incidence of approximately 200 cases per year in the United States in children under 20. Extraosseous Ewing sarcoma originating in the vagina is rare, with only 8 cases reported to date in the literature. These highly aggressive tumors require a more intensive treatment regimen compared to other vaginal masses like rhabdomyosarcoma. While the imaging findings are non-specific, awareness of this clinical entity can facilitate early diagnosis and appropriate treatment, which may improve prognosis. Read More

Pediatric head CT examinations remain a mainstay imaging modality, frequently utilized to evaluate a wide spectrum of pediatric pathology. Current pediatric head CT protocols aim to use the least amount of radiation while providing imaging of diagnostic quality. Lower radiation doses, along with other factors, can occasionally cause CT artifacts that can affect the quality and the interpretation of images. In this exhibit, we review examples of physics-based, patient-based and scanner-based CT artifacts on head CT exams, while also providing a brief explanation of the underlying physics and ways to mitigate the artifact. Imaging examples include among others: apparent posterior fossa masses due to beam hardening, apparent extra-axial fluid collections due to cupping artifact, apparent brain parenchymal hypodensities concerning for infarct, and apparent beading of intracranial vessels due to lower radiation doses administered. Awareness of these artifacts is critical for radiologists, as they can potentially lead to misdiagnosis. Read More
