Among the renal cystic diseases that result in end-stage renal disease, an important hereditary cause is medullary cystic kidney disease, which affects adults in an autosomal dominant pattern. It is characterized by progressive renal failure, tubulointerstitial fibrosis, and formation of small cysts in the renal medulla and corticomedullary junction. While the appearance of medullary/corticomedullary cysts may not be pathognomonic for medullary cystic kidney disease, encountering a patient with renal failure and medullary/corticomedullary cysts should prompt further investigation, given the implication of having the disease...

Piriformis syndrome is a common cause of lumbar, gluteal, and thigh pain, frequently associated with sciatic nerve symptoms. Potential etiologies include muscle injury or chronic muscle stretching associated with gait disturbances. There is a common pathological end pathway involving hypertrophy, spasm, contracture, inflammation, and scarring of the piriformis muscle, leading to impingement of the sciatic nerve. Ultrasound-guided piriformis injections are frequently used in the treatment of these pain syndromes, with most of the published literature describing injection of the muscle...

Pulmonary ultrasonography is a complementary study that is easy to perform at the patient bedside with no need to transfer the patient to special areas. The technique provides information with high sensitivity and specificity for different pathologies. Pulmonary ultrasonography is a very important diagnostic tool in the assessment of lung, pleural, and chest wall diseases. Pulmonary ultrasound provides low-cost analysis, easy real-time reproduction, and safety, all of which have made it a beneficial tool in the diagnostic arsenal available to medical personnel...

In healthy children, the normal vascularity index (VI) values were defined for palatine tonsils using the superb microvascular imaging (SMI), and the relationship with potential factors affecting these values was assessed. This prospective study evaluated 74 children (age range = 3-17 years, median = 13 years, SD = 6.4 years). The cases were divided into 3 subgroups based on age as 3 to 6 years (preschool), 7 to 12 years (school age), and 13 to 17 years (adolescent). Demographic data such as sex, age, and body mass index (BMI) were recorded...

Tissue elasticity is becoming a more commonly used parameter in evaluation of parenchyma in inflammatory diseases. Considering the changes in the thyroid and salivary glands with adolescence, determination of mean elasticity ranges with a function of age is necessary to apply ultrasound elastography more widely in the pediatric population.The thyroid, submandibular, and parotid glands of 127 healthy volunteers (66 males, 61 females; mean age = 10.3 ± 3.9 years; range = 3-17 years) were evaluated with shear-wave elastography...

Endovascular repair of abdominal aortic aneurysms have been performed successfully since 1991. However, 20% to 50% of these patients may develop an endoleak or continued aneurysmal sac expansion or perfusion despite stent graft coverage. Current recommendations suggest lifelong surveillance with computed tomographic angiography (CTA) at least 1 month after intervention and yearly after that. In select patients with a stable aneurysm sac on computed tomography performed 1 year after treatment, future screening could be performed with ultrasonography...

INTRODUCTION: Developmental dysplasia of the hip (DDH) is still a common and important disorder of childhood, with a prevalence of 0.1 to 2/1000 children. Using ultrasonography (US) in screening of DDH reduces the rates of open reductions and complications. In the current study, we aim to detect the optimal time for US examination for detecting DDH to prevent unnecessary repeating US examinations and treatments. METHODS: Children referred to US examination for a healthy child screening program, according to the health policy of our country, are included in the current prospective study...

Musculoskeletal injuries have been and remain a significant issue for sonographers. Despite its importance, the topic of musculoskeletal injury in sonographers has received little attention in the radiology literature. Our goal is to bring this extremely important issue to the forefront, with the hope of initiating conversations and actions leading to improved workplace practices for sonographers.

Our purpose was to assess the endoscopic ultrasonography (EUS) features of serous cystic neoplasms (SCNs) of the pancreas in determining the surgical removal compared with computed tomography (CT) and magnetic resonance imaging (MRI) features. For 33 consecutive patients with 34 surgically confirmed SCNs over the past 11 years, preoperative EUS features were compared with those of CT and MRI (CT&MRI). Besides the lesion size and location, a retrospective analysis of the various imaging features was performed by 2 observers to understand the characteristics that determine the need for surgical intervention in terms of multiplicity of locules, calcification, mural thickening, mural nodules, ductal communication, and main pancreatic duct dilatation in addition to the gross morphologic type: microcystic, macrocystic (>1 cm), mixed, or solid...

Enlargement of the fetal spleen is usually found secondary to systemic diseases and is frequently associated with hepatomegaly. By far, the most common causes of fetal splenomegaly are infectious. Other etiologies responsible for this sign are hemolytic anemia, congestive cardiac failure, metabolic disorders, and rarely, leukemia, lymphoma, and histiocytosis.We report a case of prenatal splenomegaly diagnosed at 35 weeks, confirmed in the postnatal period. The postnatal workup showed the newborn had a familial type 3 form of hemophagocytic lymphohistiocytosis (HLH)...

Meig syndrome is the triad of benign ovarian tumor, ascites, and pleural effusion. Pseudo-Meig syndrome mimics the Meig syndrome triad; however, in pseudo-Meig syndrome, the ovarian tumor usually represents a primary malignancy or metastases. Differentiating Meig from pseudo-Meig syndrome is challenging both clinically and with diagnostic imaging but is important because prognoses for these distinct entities are drastically different. Evidence-based sonographic prediction models are valuable because they can aid in this distinction...
