Comments and illustrations of the WFUMB CEUS liver guidelines: rare benign hematological focal liver lesions (hepatic extramedullary hematopoiesis, Hemophagocytic lymphohistiocytosis, reactive lymphoid hyperplasia).

The manifestation of benign hematological infiltration in the liver is a challenge due to their rare occurrence and therefore, limited awareness and the general need for biopsy and histological confirmation. Owing to the rarity of these lesions, there are limited data concerning their appearance on ultrasound and, specifically, contrast-enhanced ultrasound. In a series of papers, we have compiled the US and CEUS characteristics of rare FLL, where there are few reports and images available, in order to build up a library of these cases.

B-mode ultrasound and contrast-enhanced ultrasound for evaluation of pneumonia: A pictorial essay.

Due to their often peripheral pleural-based location, pneumonias can be visualised by B-mode ultrasound. Therefore, sonography can be used as an alternative imaging modality to chest X-ray in suspected cases of pneumonia. Depending on the clinical background of the patient, and various underlying pathological mechanisms, a heterogeneous pattern of pneumonia is seen in both B-mode lung ultrasound and contrast-enhanced ultrasound.

Inflammatory Pseudotumor of the Omentum in Contrast-enhanced Ultrasound.

Aim Of The Study: Inflammatory pseudotumor is a rare benign tumor that can occur at various body sites. Due to its rare occurrence and histological variety radiological data is heterogeneous and limited.

Case Description: We present a case of a 71-year-old man with inflammatory pseudotumor of the omentum.

Portal venous gas detection in different clinical situations.

Portal Venous Gas (PVG) provides an important differential diagnosis in the diagnose of intrahepatic reflexogenic structures. This review article is intended to provide an overview of the current literature on the detection of PVG, its special forms and important differential diagnoses, it also shows possibilities for the diagnostic procedure in the case of sonographic detection of PVG.

Evaluation and Classification of Incidentally Detected Splenic Lesions Based on B-Mode and Contrast-Enhanced Ultrasound.

Purpose: To evaluate B-mode ultrasound (B-US) and contrast-enhanced ultrasound (CEUS) patterns of focal splenic incidentalomas (FSIs), and to correlate ultrasound patterns with benignity and malignancy via histologic examination and/or the clinical course.

Materials And Methods: Between 2004 and 2021, 139 consecutive patients with an FSI detected by B-US were investigated additionally with CEUS. On CEUS, the arterial enhancement (AE) of the FSI (hyperenhancement, isoenhancement, hypoenhancement, and absent enhancement) was analyzed.

[Ultrasound systems for abdominal diagnostics - current methods, clinical applications and new technologies].

Abdominal ultrasound is the method of first choice in many clinical situations. Gray scale imaging (B-mode) and conventional Doppler techniques are nowadays complemented by contrast-enhanced ultrasound (CEUS), elastography, fat quantification and further technologies which allow multimodal characterization of organs and tissue structure using panoramic imaging, 3D-techniques and image fusion. The development of small portable devices augments the spectrum for sonographic diagnostics.

Presentation of Chloromas in B-Mode Ultrasound and Contrast-Enhanced Ultrasound.

Chloromas, also referred to as myeloid sarcomas, describe rare extramedullary tumor aggregates of malignant myeloid progenitor cells. The aim of this study was investigate the diagnostic features and characteristics of chloromas using contrast-enhanced ultrasound (CEUS). Between July 2007 and April 2021, 15 patients with 20 myeloid neoplasms and suspected chloroma manifestations were examined using B-mode US (B-US) and CEUS.

The Value of Contrast-Enhanced Ultrasound (CEUS) in the Detection of Perfusion Disturbances in Abdominal Wall Hernias Compared with Surgical and Histological Assessment.

This study aimed to evaluate the value of contrast-enhanced ultrasound (CEUS) in the evaluation of perfusion disturbance in irreducible abdominal wall hernias (AWHs). From 2006 to 2018, 50 patients with an irreducible AWH were examined using B-mode ultrasound (B-US) and CEUS. The ultrasound findings were correlated with subsequent surgical and histological results.

Diagnostic Performance of Point Shear Wave Elastography Using Acoustic Radiation Force Impulse Technology in Peripheral Pulmonary Consolidations: A Feasibility Study.

The aim of the study described here was to evaluate the diagnostic performance of lung ultrasound point shear wave elastography using acoustic radiation force impulse (ARFI) in peripheral pulmonary consolidations (PPCs). A total of 87 patients with PPCs diagnosed from April to December 2020 were included retrospectively in the study. The inclusion criteria were (i) a PPC >1 cm; (ii) valid ARFI measurements; and (iii) confirmation of the diagnosis of a PPC by histocytological examination and/or clinical and radiological follow-up.

Transcutaneous B-mode ultrasound (TUS) and contrast-enhanced ultrasound (CEUS) pattern of mediastinal tumors: a pictorial essay.

Sound reflection from bony structures and from air-filled lung parenchyma limits transcutaneous B-mode thoracic ultrasound of the mediastinum. Computed tomography and magnetic resonance imaging of the thorax are the primary overview imaging modalities for mediastinal pathologies. However, pathological processes originating from the mediastinum can be sonographically visualized and evaluated in the presence of displacing or infiltrative growth.

Assessment of Early Therapy Response of Non-Hodgkin's and Hodgkin's Lymphoma Using B-Mode Ultrasound and Dynamic Contrast-Enhanced Ultrasound.

Objectives: Here we asked, whether contrast enhanced ultrasound (CEUS) enables to judge early treatment response in malignant lymphoma as a potential guidance for further treatment.

Methods: From May 2017 to May 2018, 21 patients with histologically confirmed diagnosis of lymphoma were examined by B-mode ultrasound (B-US) and CEUS at fixed early time points after commencing therapy (days [d] 0, 15 and 30 after therapy start) and contrast enhancement patterns in target lymphoma lesions were quantified using Bracco-VUE Box® (DCE-US). To estimate the potential value of CEUS-enhancement patterns for early response prediction, patients were grouped according to their best achieved actual response into complete remission (CR) patients, partial remission (PR) patients or progressive disease (PD) patients.

Frequency of synchronous malignant liver lesions initially detected by ultrasound in patients with newly diagnosed underlying non-hematologic malignant disease: a retrospective study in 434 patients.

Introduction: This study described the frequency of malignant synchronous focal liver lesions (FLLs) in patients with newly diagnosed non-hematologic malignant disease.

Methods: From June 2013 to January 2017, 434 patients with synchronous FLLs and newly diagnosed underlying malignant disease were included in the study. The diagnosis of the FLLs was made by histology and/or contrast-enhanced imaging.

Contrast-enhanced ultrasound is helpful for differentiating benign from malignant parietal pleural lesions.

Introduction: To describe the value of contrast-enhanced ultrasound (CEUS) for the differentiation of malignant from benign parietal pleural lesions (PPLs).

Materials And Methods: From November 2005 to June 2019, 63 patients with histologically/cytologically confirmed PPLs were investigated by CEUS. On CEUS, the extent of enhancement (EE; marked or reduced/absent) and the homogeneity of enhancement (HE; homogeneous or inhomogeneous) were analyzed retrospectively.
