Aspiration pneumonia in children with neurological disorders: a new indication for lung ultrasound? A case series
AbstractAspiration pneumonia is a common cause of morbidity and mortality in both adults and children that, however, is difficult to accurately diagnose. In current literature, there are no reports or clinical research study focused on the possible use of lung ultrasound (LUS) in the diagnosis and follow-up of aspiration pneumonia in children. In this case series, we describe clinical, laboratory, radiological results as well as detailed lung ultrasound findings of three children with severe disability and diagnosed with aspiration pneumonia. In these three cases, albeit at different times, LUS played an important role in ...

A new comprehensive ultrasonic diagnostic method for celiac artery compression syndrome that hybridizes “arterial compression hook sign” and peak systolic velocity
AbstractPurposeDiagnosing celiac artery compression syndrome (CACS) is based on an imaging finding of celiac artery compression (CAC), but the diagnostic criteria are inconsistent. The study aim was to devise an ultrasonographic screening method to effectively diagnose CAC in occult CACS.MethodsThe subjects were 61 patients with suspected CACS who underwent ultrasonography at our hospital from May 2017 to December 2019 and were divided into the following two groups: the “arterial compression hook sign”-positive group (n = 15, mean age: 26.6 ± 16.4 years, six males, nine f...

Ultrasound evaluation of varicoceles: systematic literature review and rationale of the ESUR-SPIWG Guidelines and Recommendations
AbstractAlthough often asymptomatic and detected incidentally, varicocele is a relatively common problem in patients who seek medical attention for infertility problems. Ultrasound (US) is the imaging modality of choice for evaluation, but there is no consensus on the diagnostic criteria, classification, and examination technique. In view of this uncertainty, the Scrotal and Penile Imaging Working Group of the European Society of Urogenital Radiology (ESUR-SPIWG) undertook a systematic review of the available literature on this topic, to use as the basis for evidence-based guidelines and recommendations.

Diagnostic imaging of parotid gland oncocytoma: a pictorial review with emphasis on ultrasound assessment
AbstractParotid gland oncocytoma (PGO) is a rare benign epithelial tumor that usually occurs in the elderly population. The most common clinical presentation is a painless, slow-growing, non-tender, lobulated, and mobile mass. Histologically, it is composed of monotonous sheets of epithelial cells (oncocytes) with a central scar. The cross-sectional appearance is not specific, and it overlaps with other parotid lesions. On ultrasound (US), oncocytoma appears as an ovoid, well-defined, homogeneous, and hypoechoic lesion. Cystic and hemorrhagic areas as well as intralesional fat may be observed. Doppler analysis shows intrat...

AbstractPower Doppler (PD) is used widely in musculoskeletal ultrasound, especially in the assessment of structures for evidence of inflammation and in evaluating soft tissue neoplasms. We reinforce and delineate the three cardinal principles of optimising PD assessment in order to avoid false positive or false negative results; namely (1) Optimal gain settings (2) Adequate transducer pressure, and (3) Proper patient/anatomical structure-of-interest positioning with complete tissue relaxation.

Acromioclavicular osteoarthritis and shoulder pain: a review of the role of ultrasonography
AbstractAcromioclavicular joint osteoarthritis is often a cause of shoulder pain. On the other hand, imaging frequently leads to such a diagnosis, especially in elderly patients, and some authors believe it to have a poor correlation with the clinical picture. It is, however, widely accepted that such a condition can be the cause of rotator cuff impingement. In the case of shoulder pain, it is important to distinguish between symptomatic acromioclavicular osteoarthritis and other causes, especially rotator cuff pathology, which is more common. Sometimes, the clinical picture does not allow for differential diagnosis; in th...

ConclusionsFetal perfusion, welfare, and viability are related to UC function as the conveyor of all fetal volemia. Excessive UC length affects cardiac dynamics and increases peripheral vascular resistance. Further studies could validate routine use of the differential proximal and distal measurements proposed in this article, and their implications in in utero fetal heart function. We also hope that early diagnosis or UC alterations could alert neonatologists and obstetricians to clinical conditions of the fetus. (Source: Journal of Ultrasound)

Sonographic demonstration of a spontaneous rectus sheath hematoma following a sneeze: a case report and review of the literature
AbstractSpontaneous rectus sheath hematoma (SRSH) is an uncommon cause of acute abdominal pain characterized by bleeding within the rectus sheath; it is a benign condition and, in most cases, it is treated conservatively. Bleeding of the abdominal wall is an unusual condition that is quite challenging to identify promptly and can be easily overlooked during a routine physical examination. In daily practice, anticoagulant therapy is one of the main risk factors for hemorrhagic events. In this respect, we report a rare case of spontaneous hematoma of the abdominal wall (diagnosed and monitored through an ultrasound examinati...

Prenatal diagnosis of a rare isolated thoracic-type ectopia cordis with complete form: a case report
AbstractEctopia cordis (EC) is a rare malformation that occurs as an isolated lesion or as part of the pentalogy of Cantrell which is characterized by midline closure defects. This was first described by Haller et al. in 1706. EC is seen with a frequency of 5.5 –7.9 per 1 million births. It has five types that are: cervical, cervico-thoracic, thoracic, thoraco-abdominal, and abdominal. Its differentiation from the pentalogy of Cantrell, first described by Cantrell in 1958, must be done well. Thoracic type has the worst prognosis and due to this poor prog nosis in the postnatal period, termination may be offered to th...

Diagnostic accuracy of pubic symphysis ultrasound in the detection of unstable pelvis in polytrauma patients during e-FAST: the value of FAST –PLUS protocol. A preliminary experience

Indeed, there are many anatomic descriptions of the normal GE junction. The fact that GERD diagnosis was made by morphological studies was believed to be an incorrect deduction.

Evaluation of diaphragm thickening by diaphragm ultrasonography: a reproducibility and a repeatability study
ConclusionsThe results of our study have shown that diaphragm ultrasound is repeatable and reproducible when carried out by a radiologist or an intensivist with a basic curriculum in ultrasonography. The method is more accurate when using the M-mode for less experienced operators, and in this case, repeatability and reproducibility are not sufficient to make clinical decisions. No TF value lower than 36% was obtained using both techniques. This suggests the existence of a cut-off value that could be used as an initial tool to discriminate healthy subjects from those affected by diaphragmatic dysfunction.Clinical trial regi...
