BACKGROUND: Osteosarcoma typically develops during puberty with tumors arising at sites of rapid bone growth, suggesting a role for growth-regulating pathways in tumor etiology. Birthweight is one measure of perinatal growth that has been investigated as an osteosarcoma risk factor. Whether birthweight affects clinical features of osteosarcoma remains unexplored. METHOD: Six hundred seventy patients with osteosarcoma, aged 0-19 years, were identified through the California Cancer Registry...

Bulging of the inguinal region is a frequent complaint in the pediatric population and sonographic findings can be challenging for radiologists. In this review we update the sonographic findings of the most common disorders that affect the inguinal canal in neonates and children, with a focus on the processus vaginalis abnormalities such as congenital hydroceles, indirect inguinal hernias and cryptorchidism, illustrated with cases collected at a quaternary hospital during a 7-year period. We emphasize the importance of correctly classifying different types of congenital hydrocele and inguinal hernia to allow for early surgical intervention when necessary...

Low-grade (WHO I-II) gliomas and glioneuronal tumors represent the most frequent primary tumors of the central nervous system in children. They often have a good prognosis following total resection, however they can create many neurological complications due to mass effect, and may be difficult to resect depending on anatomic location. MicroRNAs have been identified as molecular regulators of protein expression/translation that can repress multiple mRNAs concurrently through base pairing, and have an important role in cancer, including brain tumors...

OBJECTIVE: There are currently no algorithms for early stratification of pediatric musculoskeletal infection (MSKI) severity that are applicable to all types of tissue involvement. In this study, the authors sought to develop a clinical prediction algorithm that accurately stratifies infection severity based on clinical and laboratory data at presentation to the emergency department. METHODS: An IRB-approved retrospective review was conducted to identify patients aged 0 to 18 who presented to the pediatric emergency department at a tertiary care children's hospital with concern for acute MSKI over a 5-year period (2008 to 2013)...

Injuries of the cervical spine are uncommon in children. The distribution of injuries, when they do occur, differs according to age. Young children aged less than 8 years usually have upper cervical injuries because of the anatomic and biomechanical properties of their immature spine, whereas older children, whose biomechanics more closely resemble those of adults, are prone to lower cervical injuries. In all cases, the pediatric cervical spine has distinct radiographic features, making the emergency radiological analysis of it difficult...

Imaging of children is complicated with a vast array of normal variants, congenital or developmental disorders, and age-dependent differential considerations. We present imaging findings of several common anatomic variants as well as physiological and maturational processes that occur in children. We compare and contrast them with pathological entities so that the reader can successfully distinguish them when interpreting pediatric imaging examinations. The content has been accrued from the authors' collective experience at a tertiary-care pediatric hospital, teaching and consulting with radiology trainees and clinicians, as well as a comprehensive review of the literature, and is intended to represent a useful error prevention tool for radiologists interpreting pediatric studies...

Neck masses present as palpable lumps and bumps in children with acquired lesions more common than congenital ones. Assessment of the anatomical site of origin, signal, and contrast enhancement characteristics may help define the etiology of the lesions, eg, developmental, inflammatory, vascular, or neoplastic. The age of the patient along with detailed clinical history and physical exam findings are important element to narrow down the differential diagnosis. The correct final diagnosis is essential to guide treatment as well as the urgency of intervention...

Renal and urinary tract imaging is commonly performed in the pediatric population, particularly in the setting of suspected or known congenital anomalies. In most cases, adequate anatomic assessment can be achieved using ultrasound and fluoroscopic techniques, and evaluation of differential renal function and urinary tract drainage can be accomplished with renal scintigraphy. However, in a subset of children, anatomic or functional questions may remain after this routine evaluation. In this setting, magnetic resonance imaging (MRI) tailored to evaluate the kidneys and urinary tract, known as MR urography (MRU), can be used to depict the kidneys, ureters, and urinary bladder in detail and to determine differential renal function and assess urinary tract drainage...

The various childhood suprasellar tumors, while pathologically distinct, present similar clinical and surgical challenges as a result of their common anatomic location. These lesions are in close proximity to or may invade the optic nerve and chiasm, pituitary gland and infundibulum, hypothalamus, and third ventricle, leading to presenting features including visual field loss, impairment in visual acuity, endocrine dysfunction, and hydrocephalus. Though many suprasellar lesions are relatively benign in pathology, treatment may be complicated by high surgical morbidity resulting from damage to the hypothalamic-pituitary axis...

REVIEW
Wojciech Mądry, Maciej A Karolczak
The diagnosis of the congenital heart defects, among others totally anomalous pulmonary venous drainage, is based on echocardiography. While the visualization of intracardiac structures rarely causes significant difficulties, the vessels positioned outside the heart, e.g. the pulmonary veins, are often hidden behind tissues impermeable to ultrasounds, which may necessitate the use of other imaging methods, such as computer tomography, nuclear magnetic resonance or angiocardiography. The serious limitation of these techniques, especially in pediatric age, is the necessity to administer general anesthesia and contrast media...

Human cystic echinococcosis, a zoonotic infection caused by Echinococcus granulosus, remains a largely extended public health problem in endemic regions. Hydatid cyst disease can occur in all viscera and soft tissues, although the liver and the lungs are the most commonly involved organs. Primary hydatid disease of the soft tissue is extremely rare, even in endemic areas, and accounts for 0.5-5.4 % of all hydatid disease cases, with very little data on the incidence of subcutaneous echinococcosis. The paper will be focused on analyzing this extremely rare disease...

Myoepithelial neoplasms were originally described in the salivary glands but their spectrum has been expanding with reports in other locations, including soft tissue. Intracranial cases are exceptionally rare outside the sellar region where they are assumed to be arising from Rathke pouch rests. Two cases of pediatric intracranial myoepithelial neoplasm in the interhemispheric fissure and the right cerebral hemisphere are reported here. Imaging studies suggest that the second case was associated with cerebrospinal fluid dissemination...

Astrocytoma is the most common childhood brain tumor. Anaplastic astrocytoma (AA) are high grade gliomas (HGG), found very rarely in pediatric patients. AA mainly results from a dedifferentiation of a low grade astrocytoma. Clinical features of supra-tentorial tumors vary according to their anatomic location, biologic aggressiveness and age of the patient. They can be either completely asymptomatic or present with signs of raised intracranial pressure, seizures (about 40% of cases), behavior changes, speech disorders, declining school performance, or hemiparesis...
