Perception plays a significant role in the interpretation of images (Fig.1). A medical image perception society (MIPS) now exists with a goal to improve the understanding of imaging perceptual factors. Perception in sonography is different than other modalities where images are produced in a specifically formatted manner and then evaluated later by the observer (passive perception). Ultrasound is performed in a less standardized process to provide the best acoustic window of the region of concern. Image production requires the operator’s perceptual skills while acquiring the images (interactive perception). The study purpose was to determine if experience, knowledge base or scan time correlates with an imagers perceptual ability to visualize the normal appendix. Read More

Wolman disease is a rare autosomal recessive inherited disease characterized by storage of cholesterol esters and triglycerides in lysosomes due to a deficiency of lysosomal acid lipase. Clinical signs such as persistent vomiting, diarrhea, hepatosplenomegaly, growth retardation and liver dysfunction occur in the first weeks of life. Most cases die in the first year of life. Here, we aim to present radiological findings of Wolman disease.
An asymptomatic girl two months of age was admitted to the pediatric genetic disease service with the history of Wolman disease in two brothers who had died in the neonatal period. Abdominal X-ray imaging displayed calcification of the bilateral adrenal gland regions. Hepatosplenomegaly and bilateral adrenal gland posterior acoustic shadowing due to calcifications were revealed by abdominal sonography. Magnetic resonance imaging showed enlarged hypointense adrenal glands in all sequences and hepatosplenomegaly. The lysosomal acid lipase levels were low compatible with Wolman disease.
Multimodality radiologic imaging methods should be performed to display hepatosplenomegaly, hepatosteatosis, bilateral adrenal gland enlargement and calcification in Wolman disease. Read More

Sacrococcygeal teratoma (SCT) is one of the most common tumors of the newborn. SCT is seen frequently in the presacral region and in forms of solid or mixed solid and cystic masses. Only 10-15 % of all sacrococcygeal teratomas are in pure cystic form. Here, in this case, we aimed to present sonographic and magnetic resonance images (MRI) of a newborn with pelvic cystic mass and bilateral hydronephrosis that were seen on prenatal ultrasonography.
An operation was planned for two days of age girl patient for cystic pelvic mass and bilateral hydronephrosis detected by prenatal sonography during the third trimester. On her abdominal X-ray radiography, there was no bowel gas at the midline pelvis. The patient was referred to the sonography unit with the suspicion of a duplication cyst. Abdominal sonography revealed bilateral hydroureteronephrosis, bladder wall thickening, and a 75x55x32 mm pure cystic mass located between the rectum and bladder. The mass had a fine septa at the inferior site. Abdominal MRI showed that the mass had no connection with the spinal canal or solid component. The patient was operated and the diagnosis of purely cystic sacrococcygeal teratoma was confirmed histopathologically.
Anterior meningocele, tail gut cyst, rectal duplication cyst, and cystic sacrococcygeal teratomas are common lesions of the presacral region diagnosed in the prenatal or antenatal period. Sacrococcygeal teratoma should be kept in mind in patients with presacral cystic mass in the neoatal period and radiologic methods are helpful for displaying the extent and content of a cystic mass.

Post-traumatic intercostal lung herniation (ICLH) is defined as a protrusion of lung tissue through a defect in the intercostal space musculature and is a rare result of chest trauma. Due to its rarity, the management and imaging work up has been based on the adult experience, with Computed Tomography (CT) the most common diagnostic tool and surgery the primary management approach.
The purpose of this study is to describe the sonographic appearance and technique utilized in diagnosis of post-traumatic ICLH and to support their inclusion in a proposed imaging algorithm to aid in management in the pediatric population. Read More

The purpose of this educational exhibit poster is to increase the awareness of stump appendicitis using two case examples.

Stump appendicitis is rare, with sixty-one cases identified in the literature between 1945 and 2005. Of the two common techniques of appendicectomy, ligation and invagination, the former can leave a residual stump with a potential lumen for the pathophysiological process of appendicitis to recur. Remnant stump lengths of greater than 5 mm are considered to have a higher risk of leading to stump appendicitis, acting as a potential reservoir for a faecolith. Whilst ultrasound has been commonly used to diagnose acute appendicitis for over 30 years, its utility in pre-operative identification of stump appendicitis in patients post-appendicectomy has only been documented more recently. Traditional sonographic criteria for diagnosing acute appendicitis have been applied to the appendiceal stump, with a transverse diameter greater than 6 mm, non-compressibility and wall hyperaemia all being concerning for stump appendicitis. Secondary sonographic signs of acute appendicitis, such as echogenic peri-appendiceal mesentery, can also indicate stump inflammation.

Two case examples are presented, both in patients who are nine years old. One patient had surgically confirmed stump appendicitis. The second had sonographic features of stump appendicitis which settled with antibiotics without requiring surgery.

Inflammation of the base or stump of a surgically removed appendix is an uncommon, and likely under-recognised condition in both children and adults. The majority of cases have had previous open appendicectomy, which is in contrast to a theory that laparascopic surgery is a potential factor in incomplete removal of the appendix due to poor visualisation of the appendiceal base. Both methods of appendicectomy, ligation or invagination, have been associated with stump appendicitis. Suspicion of the condition and prompt diagnosis can potentially reduce the risk of serious complications due to delayed treatment (perforation, abscess formation), or misdiagnosis (constipation, gastroenteritis).

Whilst the possibility of appendicitis is usually dismissed in patients with a history of appendicectomy, sonographers should be aware of stump inflammation in such patients that present with RIF pain from weeks to decades after surgery.

Morphological and functional carotid artery alteration can occur already in youth ages, essentially in presence of cardiovascular risk factors. Studies have showed that sonographic assessment of carotid artery (CA) Intima-Media Thickness (IMT) serves as prognostic factors for cardio-vascular disease also in youth patient population. As functional changes occur earlier than vessel wall morphological changes, this might be indicated by a decrease in vessel elasticity prior to the increase of IMT. This hypothesis indicates to use an early functional parameter for cardiovascular risk assessment.
This study was designed to assess and evaluate IMT as well as CA vessel elasticity in three groups, in young sportsmen and youth volunteers without any cardio-vascular risk factors (CV-RF) comparing to youth volunteers with CV-RF. Read More
