“…The superficial location of the testis coupled with high-frequency linear transducers allows detailed grey-scale sonographic and sensitive colour Doppler imaging. Contrast-enhanced ultrasound (CEUS) also provides further assessment of vascularity in equivocal cases and may become more important in the future [1].…”

Scrotal emergencies represent a small proportion of admissions to the emergency department; however, the intimate nature and potential for serious outcome often cause great anxiety. Rapid assessment is required to exclude fertility-threatening conditions and expedite surgical management. Ultrasound is an essential tool in acute scrotal assessment as it allows rapid, radiation-free, highresolution imaging and, importantly, assessment of vascularity with colour Doppler imaging. In the presentation of the acute scrotum, the ''on-call'' practitioner will frequently be asked to exclude pathology requiring surgical management, in particular torsion of the spermatic cord. To provide an accurate evaluation the individual is required to have an understanding of scrotal anatomy, sonographic technique and recognition of pathology. This review article will familiarise the reader with the sonographic findings of common acute scrotal pathology.Sommario Le emergenze scrotali rappresentano una piccola percentuale di accessi al pronto soccorso, ma la natura intima e la possibilità di esiti seri sono spesso causa di grande ansia. E' necessaria una valutazione rapida, al fine di escludere condizioni di pericolo per la fertilità e accelerare il trattamento chirurgico. L'ecografia è uno strumento essenziale per la valutazione dello scroto acuto in quanto rapida, esente da radiazione, ad alta risoluzione e, soprattutto, permette la valutazione della vascolarizzazione con colour Doppler. Nello scroto acuto l'ecografista spesso verrà chiamato a escludere patologie che richiedono un trattamento chirurgico, in particolare la torsione del funicolo spermatico. Al fine di fornire una valutazione precisa è tenuto ad avere una conoscenza dell'anatomia scrotale, della tecnica ecografica e a conoscere le varie patologie. Questo articolo di revisione ha lo scopo di familiarizzare il lettore con gli aspetti ecografici della patologia scrotale acuta più frequente.

“…In contrast, CEUS is not reliable for monitoring during thermal ablation, because MWA creates so-called microbubbles [14], which interfere with CEUS imaging. After ablation, CEUS is reported to predict successful treatment of soft tissue and is used to identify local recurrences of malignant neoplasia [21,26]. In particular, the imaging of malignant lesions benefits from CEUS as success depends on exact ablation.…”

Zusammenfassung ▼Hintergrund: Mikrowellenablationen (MWA) stellen eine neuartige thermoablative Behandlung für benigne Schilddrüsenknoten dar. Ziel war es, die benötigte Energie pro ml Volumenreduktion zu benutzen, um die benötigte Energie für ein volume-of-interest (VOI) abschätzen zu können. Methode: 25 Patienten mit 25 Knoten (6 solide, 13 komplex und 6 zystisch) wurden durch MWA behandelt. Die übertragene Energie (E) wurde mit der Volumenveränderung (Δ V) nach 3 Monaten korreliert. Der Energiebedarf pro ml Volumenreduktion wurde durch E/Δ V bestimmt. Ergebnisse: MWA zeigte eine signifikante (p < 0,0001) Volumenreduktion (Δ V) im Mittel von 12,4 ± 13,0 ml (range: 1,5 -63,2 ml) und eine relative Reduktion von 52 ± 16 % (range: 22 -77 %). Es zeigte sich eine positive Korrelation zwischen E und Δ V (r = 0,82; p < 0,05). Die mittlere E/Δ V war 1,52 ± 1,08 (range: 0,4 -4,6) kJ/ml für alle Knoten und 2,30 ± 1,5 (0,9 -4,6); 1,5 ± 0,9 (0,4 -3,6); 0,75 ± 0,25 (0,4 -1,2) kJ/ml für solide, komplexe und zystische Knoten mit einer signifikanten Differenz der in E/Δ V zwischen soliden und zystischen Knoten (p < 0,03 Abstract ▼Purpose: Microwave ablation (MWA) represents a novel thermal ablative treatment of benign thyroid nodules. The aim was to determine the energy required per ml volume reduction in order to match the required energy to the volume-of-interest (VOI). Materials and Methods: 25 patients with 25 nodules (6 solid, 13 complex and 6 cystic) were treated by microwave ablation (MWA). The transmitted energy (E) was correlated with the volume change (Δ V) after 3 months. The energy required per ml volume reduction after 3 months was calculated by E/Δ V. Results: MWA resulted in a significant (p < 0.0001) volume reduction (Δ V) with a mean of 12.4 ± 13.0 ml (range: 1.5 -63.2 ml) and relative reduction of 52 ± 16 % (range: 22 -77 %). There was a positive correlation between E and Δ V (r = 0.82; p < 0.05). The mean E/Δ V was 1.52 ± 1.08 (range: 0.4 -4.6) kJ/ml for all nodules and 2.30 ± 1.5 (0.9 -4.6), 1.5 ± 0.9 (0.4 -3.6), 0.75 ± 0.25 (0.4 -1.2) kJ/ ml, respectively, for solid, complex and cystic nodules with a significant difference in E/Δ V for solid and cystic (p < 0.03). Conclusion: The energy required per volume depends on the nodule consistency. Solid nodules require more energy than cystic ones. The estimation of the energy needed per volume-of-interest as an additional parameter should help to avoid under-or overtreatment. Key Points:▶ The estimated required energy for a volumeof-interest depends on the nodule consistency ▶ In solid nodules a higher energy transmission than in cystic nodules is recommended ▶ The energy transmission as an additional marker to ultrasound is helpful for improving periprocedural monitoring This document was downloaded for personal use only.

“…Distinguishing a segmental infarction from a tumour is of critical importance in order to avoid unnecessary orchiectomy [2]. Newer techniques of contrastenhanced ultrasound (CEUS) [3] and real-time tissue elastography (RTE) [4] are being used to aid in the differentiation of indeterminate intra-testicular abnormalities [5,6]. We document the evolving appearances of bilateral testicular infarction on CEUS and RTE, which allowed for conservative management to resolution.…”

Segmental testicular infarction is a rare cause of acute scrotal pain. The appearances on grey-scale sonography are often indistinguishable from that of a testicular tumour, resulting in unnecessary orchiectomy. We report a case of acute bilateral testicular infarction, of unknown etiology, which was conservatively managed to resolution following a confident diagnosis achieved with the aid of contrast-enhanced ultrasound (CEUS) and real-time tissue elastography (RTE) along with conventional grey-scale and Doppler sonography. The evolving appearances on each of the sonographic modalities are described. We discuss the importance of complementing conventional sonography with CEUS and RTE in order to make a confident diagnosis and avoid unnecessary surgical intervention.Riassunto L'infarto testicolare segmentale è una causa rara di dolore scrotale acuto. L'aspetto ecografico, in scala di grigi, è spesso indistinguibile da quello di un tumore testicolare, con conseguenti orchiectomie inutili. Riportiamo un caso di infarto testicolare acuto bilaterale, ad eziologia sconosciuta, gestito in maniera conservativa fino a risoluzione, dopo una diagnosi realizzata con l'ausilio di ecografia con messo di contrasto (CEUS) e elastosonografia tessutale in tempo reale (RTE), ecografia convenzionale in scala di grigi e Doppler. Sono descritti gli aspetti, in ciascuna delle modalità ecografiche, dell'evoluzione delle lesioni. Discutiamo l'importanza della complementarietà dell'ecografia convenzionale con CEUS e RTE per effettuare una diagnosi di certezza ed evitare un inutile intervento chirurgico.
