Contrast-enhanced ultrasound (CEUS) in pediatric blunt abdominal trauma

Diagnostic insights into splenic pathologies: the role of multiparametric ultrasound

Ultrasound (US) evaluation of the spleen is mandatory in the assessment of patients with chronic liver disease, and splenomegaly can be a sign of systemic diseases. However, due to the lack of distinctive ultrasound findings in specific splenic pathologies, clinical diagnosis can be very challenging. Splenomegaly, defined by increased splenic dimensions, can indicate underlying systemic conditions and is a common manifestation of portal hypertension (PH). Ultrasound and Doppler techniques help assessing splenic involvement in PH. Splenic stiffness measurement, using elastography, offers additional diagnostic accuracy, especially when liver stiffness measurements are inconclusive. CEUS enhances the diagnostic capability for focal splenic lesions, differentiating between benign and malignant lesions by their distinct enhancement patterns, and plays also a critical role in the context of splenic traumatic pathology. Overall, CEUS significantly improves the characterization of splenic pathology, reducing the need for invasive procedures and ensuring appropriate patient management. This review article describes the normal US findings of the spleen and examines the role of multiparametric US in the evaluation of the most common splenic pathologies encountered in the daily clinical practice.

The Diagnosis and Management of Pediatric Blunt Abdominal Trauma-A Comprehensive Review

Blunt abdominal trauma in childhood has always been full of diagnostic and therapeutic challenges that have tested the clinical and radiological skills of pediatric surgeons and radiologists. Despite the guidelines and the studies carried out so far, to this day, there is no absolute consensus on certain points of view. Around the world, a paradigm shift towards non-operative treatment of hemodynamically stable children, with low complication rates, is noticeable. Children with blunt abdominal trauma require a standardized methodology to provide the best possible care with the best possible outcomes. This comprehensive review systematizes knowledge about all aspects of caring for children with blunt abdominal trauma, from pre-hospital to post-hospital care.

Optimizing Advanced Imaging of the Pediatric Patient in the Emergency Department: Technical Report

Advanced diagnostic imaging modalities, including ultrasonography, computed tomography, and magnetic resonance imaging, are key components in the evaluation and management of pediatric patients presenting to the emergency department. Advances in imaging technology have led to the availability of faster and more accurate tools to improve patient care. Notwithstanding these advances, it is important for physicians, physician assistants, and nurse practitioners to understand the risks and limitations associated with advanced imaging in children and to limit imaging studies that are considered low value, when possible. This technical report provides a summary of imaging strategies for specific conditions where advanced imaging is commonly considered in the emergency department. As an accompaniment to the policy statement, this document provides resources and strategies to optimize advanced imaging, including clinical decision support mechanisms, teleradiology, shared decision-making, and rationale for deferred imaging for patients who will be transferred for definitive care.

Use of CEUS for Imaging Evaluation of Pediatric Peritonsillar Abscess

PURPOSE

Peritonsillar abscess can be diagnosed by B-mode ultrasound and cross-sectional imaging. The latter (with MRI being the modality of first choice in children) is associated with higher effort and risk for pediatric patients due to the administration of X-rays and/or the need of sedation. The purpose of this study is to evaluate whether the introduction of CEUS into the diagnostic algorithm for suspected pediatric peritonsillar abscess is suitable and advantageous.

MATERIALS AND METHODS

Single-institution retrospective review of data of pediatric patients who were presented to the department of pediatric radiology for sonographic evaluation under the suspicion of peritonsillar abscess. Diagnostic performance of CEUS was evaluated by using surgical exploration or clinical follow-up as the reference standard.

RESULTS

284 children included in the study underwent B-mode ultrasound. Mean age of all patients was 6,23 years. Peritonsillar abscess was the diagnosis in 42 patients. Diagnosis of peritonsillar abscess was made by B-mode ultrasound alone in 13 of 42 patients (31 %). In 17 of 42 patients (40 %), diagnosis was made by a combination of B-mode ultrasound and CEUS. Sensitivity rose from 37 % to 86 % in cases where B-mode ultrasound remained unclear and CEUS was used.

CONCLUSION

Contrast-enhanced ultrasound (CEUS) is suitable and efficient for the diagnosis of peritonsillar abscess in pediatric patients. It increases the sensitivity for the diagnosis of peritonsillar abscess and thereby reduces the need of additional cross-sectional imaging for the pediatric patients.

Contrast-enhanced and conventional ultrasound images of renal wounds after partial nephrectomy

OBJECTIVES

To observe the features of conventional ultrasound (US) and contrast-enhanced ultrasound (CEUS) images of renal wounds after minimally-invasive partial nephrectomy (MIPN) and evaluate their severity using these two modalities.

METHODS

This prospective, observational study included 120 patients who underwent MIPN from April to December 2019 in our hospital. The postoperative US images were evaluated and classified, and contrast extravasation characteristics of CEUS were recorded. The correlation between the classification system and perioperative factors was analyzed.

RESULTS

Eighty-five patients underwent US and CEUS after MIPN. Conventional US images were classified into three grades according to the surface morphology of renal wounds and overall shape of the kidney around the incision. Univariable and multivariable analyses indicated that the N component of the R.E.N.A.L. score and the resection range were preoperative and intraoperative factors, respectively, related to the US image grades (UIGs). A deep location and expanded excision contributed to an increased UIG. The extravasation rate increased with the UIG (Spearman correlation rho=0.247, P=0.022), and a higher UIG prolonged the length of extravasation. The depth of the tumor and resection range were related to the UIG.

CONCLUSIONS

US and CEUS were feasible and repeatable methods that reflect the morphologic changes of renal wounds after MIPN and may be useful for evaluating their severity.

Structured reporting of computed tomography in the polytrauma patient assessment: a Delphi consensus proposal

OBJECTIVES

To develop a structured reporting (SR) template for whole-body CT examinations of polytrauma patients, based on the consensus of a panel of emergency radiology experts from the Italian Society of Medical and Interventional Radiology.

METHODS

A multi-round Delphi method was used to quantify inter-panelist agreement for all SR sections. Internal consistency for each section and quality analysis in terms of average inter-item correlation were evaluated by means of the Cronbach's alpha (Cα) correlation coefficient.

RESULTS

The final SR form included 118 items (6 in the "Patient Clinical Data" section, 4 in the "Clinical Evaluation" section, 9 in the "Imaging Protocol" section, and 99 in the "Report" section). The experts' overall mean score and sum of scores were 4.77 (range 1-5) and 257.56 (range 206-270) in the first Delphi round, and 4.96 (range 4-5) and 208.44 (range 200-210) in the second round, respectively. In the second Delphi round, the experts' overall mean score was higher than in the first round, and standard deviation was lower (3.11 in the second round vs 19.71 in the first round), reflecting a higher expert agreement in the second round. Moreover, Cα was higher in the second round than in the first round (0.97 vs 0.87).

CONCLUSIONS

Our SR template for whole-body CT examinations of polytrauma patients is based on a strong agreement among panel experts in emergency radiology and could improve communication between radiologists and the trauma team.

Radiation Dose Reduction Opportunities in Vascular Imaging

Computed tomography angiography (CTA) has been the gold standard imaging modality for vascular imaging due to a variety of factors, including the widespread availability of computed tomography (CT) scanners, the ease and speed of image acquisition, and the high sensitivity of CTA for vascular pathology. However, the radiation dose experienced by the patient during imaging has long been a concern of this image acquisition method. Advancements in CT image acquisition techniques in combination with advancements in non-ionizing radiation imaging techniques including magnetic resonance angiography (MRA) and contrast-enhanced ultrasound (CEUS) present growing opportunities to reduce total radiation dose to patients. This review provides an overview of advancements in imaging technology and acquisition techniques that are helping to minimize radiation dose associated with vascular imaging.

Influence of Percutaneous Drainage Surgery and the Interval to Perform Laparoscopic Cholecystectomy on Acute Cholecystitis through Genetic Algorithm-Based Contrast-Enhanced Ultrasound Imaging

To discuss the optimal interval time between genetic algorithm-based ultrasound imaging-guided percutaneous drainage surgery (PTGD) and laparoscopic cholecystectomy (LC), 64 cholecystitis patients were selected as the research objects and evenly divided into experimental group (intelligent algorithm was adopted to recognize patients’ ultrasonic images) and control group (professional doctors carried out diagnosis). 92 acute cholecystitis patients undergoing PTGD were divided into three groups. 30 out of the 92 patients received LC within 2 months and were defined as the early group. 32 were performed with LC within 2 to 4 months and were defined as the metaphase group. 28 underwent LC over 4 months and were defined as the late-stage group. The average operation time, the transition from LC to laparotomy, the average postoperative hospital stay, and the incidence of complications of the three groups were compared. The results revealed that the comparison of the diagnostic accuracy and comprehensive effectiveness between experimental group and control group demonstrated that the differences were statistically significant ( $P<0.05$ ). When the optimal interval of implementing LC after PTGD was realized, the corresponding values of the early group were 88.5 minutes, 16.67%, 8.13 days, and 13.75%. Those of the metaphase group were 49.91 minutes, 3.13%, 4.97 days, and 9.52%. Those of the late stage group were 68.78 minutes, 10.71%, 7.09 days, and 11.96%. To sum up, the diagnostic accuracy and comprehensive effectiveness of intelligent algorithm were higher than those of conventional ultrasound, and the optimal interval time of implementing LC after PTGD was 2 to 4 months.

Pediatric trauma and the role of the interventional radiologist

PURPOSE

While interventional radiologists occupy a critical role in adult trauma management, the role of interventionalist in pediatric trauma continues to evolve. The indications for transarterial embolization (TAE) are significantly different in pediatric patients in whom non-operative management (NOM) has a much more prominent role than in adults. Contrast extravasation on imaging may not require acute surgical or interventional management as it would in an adult. There are also areas in which pediatric interventional radiology is increasingly useful such as pelvic TAE in failed management, or splenic embolization to treat bleeding without the loss of splenic function inherent to surgical splenectomy. The rapid evolution of techniques and devices in pediatric patients is also changing what interventions are possible in pediatric trauma management which necessitates frequent reassessment of the guidelines and interventional radiology's role in caring for these patients.

CONCLUSION

This review seeks to consolidate the recent literature to describe the evolving role of the interventional radiologist in pediatric trauma management.

The Technique and Advantages of Contrast-Enhanced Ultrasound in the Diagnosis and Follow-Up of Traumatic Abdomen Solid Organ Injuries

Trauma is one of the most common causes of death or permanent disability in young people, so a timely diagnostic approach is crucial. In polytrauma patients, CEUS (contrast enhanced ultrasound) has been shown to be more sensitive than US (ultrasound) for the detection of solid organ injuries, improving the identification and grading of traumatic abdominal lesions with levels of sensitivity and specificity similar to those seen with MDCT (multidetector tomography). CEUS is recommended for the diagnostic evaluation of hemodynamically stable patients with isolated blunt moderate-energy abdominal traumas and the diagnostic follow-up of conservatively managed abdominal traumas. In this pictorial review, we illustrate the advantages and disadvantages of CEUS and the procedure details with tips and tricks during the investigation of blunt moderate-energy abdominal trauma as well as during follow-up in non-operative management.

Identification of secondary splenic lymphoma with contrast-enhanced ultrasound in the pediatric population. A case report

Contrast-enhanced ultrasound scan (CEUS) is the application of ultrasound contrast agents (UCAs) to traditional ultrasound. Our aim is to report the use of CEUS for a prompt assessment of a suspected secondary splenic lymphoma in a child, which, in our experience, has allowed an accurate description of the parenchymal perfusion and vascularization pattern, leading to a confident diagnosis. We suggest that CEUS will replace Magnetic resonance imaging (MRI) or Computed tomography (CT) as standard imaging option for differential diagnosis of spleen lesions in pediatric population. As a result this will lead to decreasing the overall use of ionizing radiation and reducing the time interval to a certain diagnosis.

Contrast-enhanced ultrasound of blunt abdominal trauma in children

Trauma is the leading cause of morbidity and mortality in children, and rapid identification of organ injury is essential for successful treatment. Contrast-enhanced ultrasound (CEUS) is an appealing alternative to contrast-enhanced CT in the evaluation of children with blunt abdominal trauma, mainly with respect to the potential reduction of population-level exposure to ionizing radiation. This is particularly important in children, who are more vulnerable to the hazards of ionizing radiation than adults. CEUS is useful in hemodynamically stable children with isolated blunt low- to moderate-energy abdominal trauma to rule out solid organ injuries. It can also be used to further evaluate uncertain contrast-enhanced CT findings, as well as in the follow-up of conservatively managed traumatic injuries. CEUS can be used to detect abnormalities that are not apparent by conventional US, including infarcts, pseudoaneurysms and active bleeding. In this article we present the current experience from the use of CEUS for the evaluation of pediatric blunt abdominal trauma, emphasizing the examination technique and interpretation of major abnormalities associated with injuries in the liver, spleen, kidneys, adrenal glands, pancreas and testes. We also discuss the limitations of the technique and offer a review of the major literature on this topic in children, including an extrapolation of experience from adults.

The role of interventional radiology in hepatic and renal hemorrhage embolization: single center experience and literature review

Background and aim:

Intraabdominal hemorrhage secondary to liver and kidney injury is a major cause of morbidity and mortality. Endovascular arterial embolization is an established interventional radiology technique used to treat active bleeding, and its role in managing abdominal hemorrhages is growing, given the increasing trend for conservative treatment. Our study aims to retrospectively evaluate the technical and clinical results and the possible complications of arterial embolization procedures performed in emergency, in post-traumatic, iatrogenic, and pathological hepatic and renal bleedings.

Methods:

We performed a ten-year, single-center retrospective survey (from January 2010 to December 2019) of all patients treated in emergency by intra-arterial embolization of liver and kidney bleeding. Preliminary CT angiography studies were evaluated, as well as the angiographic findings. Materials used, procedural data, and clinical outcomes, including complications, were recorded.

Results:

The diagnostic angiography showed a single source of bleeding in 20 cases (66.7%), two bleeding vessels in 4 cases (13.3%), and multiple hemorrhagic sources in 6 cases (20%). All bleeding sources were successfully embolized; in 12 patients (40%), complete embolization was achieved with coils and 18 patients (60%) with hemostatic sponges. In one case, a second embolization procedure was performed for the persistence of hemodynamic instability. No major post-procedural complications were recorded. The mean procedure duration was 65.1 minutes.

Conclusions:

Based on our experience and literature data, the treatment of endovascular embolization in acute abdominal bleeding of hepatic and renal origin represents the treatment of choice, as it can provide complete therapeutic success in hemodynamically stable patients. (www.actabiomedica.it)

Can contrast enhanced ultrasound (CEUS) be useful in the diagnosis of ovarian torsion in pediatric females? A preliminary monocentric experience

PURPOSE

To describe contrast enhanced ultrasound (CEUS) characteristics of ovarian torsion in pediatric females, assessing the potential diagnostic advantages of method as well as its limitations.

MATERIALS AND METHODS

A retrospective study design was used. Between January 2018 and December 2020 we analyzed all pediatric females who underwent explorative surgery with a suspected diagnosis of ovarian torsion, and who were previously evaluated by conventional ultrasound (US), color-Doppler ultrasound (CDUS) and CEUS.

RESULTS

We examined twenty pediatric females with a median age of 12 years. US identified 9/20 ovarian complex masses against 13/20 by CEUS. At US abdominal free fluid was shown in 13/20 patients and in 18/20 cases with CEUS. In our case series the evaluation of contrast enhancement at CEUS in the detection of ovarian torsions revealed a sensitivity of 94.1%, a specificity of 100% and an overall accuracy of 95%.

CONCLUSION

Although there is a known ultrasound semeiotics suggestive of ovarian torsion, it is not always possible to obtain a diagnosis of certainty with conventional US even with CDUS. The study reports that complementation with CEUS showed excellent agreement with surgery obtaining a diagnosis in almost all the pediatric females examined.

Contrast-Enhanced Ultrasound (CEUS) in Non-Traumatic Abdominal Emergencies

Conventional ultrasound imaging (US) is the first-line investigation in acute non-traumatic abdominal emergencies, but sometimes it needs further examinations, such as computed tomography (CT), to reach a certain diagnosis. Contrast-enhanced ultrasound (CEUS), through injection of contrast medium, may provide the radiologist with additional information that could not be investigated with baseline US. It could help reach a diagnosis and rapidly determine the proper therapy in an emergency setting. The purpose of this review is to explain and illustrate the various possibilities and limitations of CEUS in acute non-traumatic abdominal diseases, in particular acute inflammation, parenchymal infarcts, and hemorrhages.

Traumatic Gallbladder Perforation in Children - Case Report and Review

BACKGROUND

 Gallbladder perforation is a very rare finding in children. Clinical and radiografic presentations are often vague. Hence it is a challenging diagnosis, often missed during initial evaluation with potentially fatal consequences. The aim of this case report and review was to identify factors that might help to diagnose and manage future cases.

METHODS

 We present a case of gallbladder perforation in an 8-year-old child after blunt abdominal trauma caused by a handlebar in which imaging modalities such as ultrasound and magnetic resonance imaging (MRI) helped us to determine proper management. We identified and evaluated comparable cases for isolated traumatic gallbladder injury. A review of the recent literature was performed by online search in Pubmed and Google Scholar using "gallbladder injury in children", "gallbladder perforation children", "blunt abdominal trauma children" as keywords. We focused on articles exclusively in the pediatric section. The literature from the period 2000-2020 was taken into account to review the state of the art in diagnosis and management.

RESULTS AND CONCLUSION

 Recent literature for gallbladder injury in pediatrics is sparse compared to the adult counterpart. Only eight published cases of isolated gallbladder injury in children were identified. Since the onset of symptoms may not develop acutely and often develops in an indistinct manner, radiografic examinations play an important role in the diagnostic progress. The authors advise caution in cases of blunt abdominal trauma especially involving handlebars, intraperitoneal free fluid, and severe abdominal pain. We advocate high suspicion of gallbladder perforation if the gallbladder wall displays discontinuation or cannot be definitively differentiated in sonografic examination. Echogenic fluid within the gallbladder should always lead to suspicion of intraluminal bleeding. Repeated clinical and imaging examinations are mandatory since the onset of signs and symptoms may be delayed.

KEY POINTS

  · Awareness of gallbladder perforation in blunt abdominal trauma of the upper abdomen.. · Particularly high index of suspicion in cases involving handlebar injuries.. · Repeated clinical and imaging examinations are highly recommended..

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

BACKGROUND

Extended focused abdominal sonography for trauma (e-FAST) is part of the primary survey in patients with high-energy trauma. However, it does not identify patients with retroperitoneal haemorrhage associated with significant pelvic trauma. A traumatic diastasis of pubic symphysis, as well as an 'open book' (OB) pelvic injury, is a diagnostic clue to recognize unstable pelvis with higher risk of bleeding. FAST-PLUS (FAST-PL pleural -US ultrasound of symphysis) protocol is an addendum to the e-FAST, which takes into account the study of the pubic symphysis in a single transverse scan after the traditional focused evaluation of the abdomen and thorax.

OBJECTIVES

The aim of this study is to determine the value of FAST-PLUS protocol in the evaluation of pubic symphysis injuries and the identification of 'open book' (OB) unstable pelvic fractures.

METHODS

Between January 2018 and December 2019, we retrospectively reviewed 67 polytraumatised patients with clinical suspicion of pelvic instability and with known anteroposterior pelvis compression injuries who underwent e-FAST with an additional transverse scan of the pubic symphysis, named the FAST-PLUS protocol and computed tomography (CT) exam in order to assess the correlation between them in defining the presence or absence of pubic symphyseal widening (SW). A cutoff value of 2.5 cm in transverse diameter was used to diagnose OB unstable pelvic injury. The results were analysed using Cohen's test, which uses the Kappa value as the reference index.

RESULTS

The analysis carried out to assess the degree of agreement between FAST-PLUS and CT showed 5/67 patients (7.5%) with a critical pubic SW (> 2.5 cm transverse diameter) suggestive of unstable OB pelvic injury and 62/67 (92,5%) without any signs of SW at FAST-PLUS. At CT, findings of unstable OB pelvic fracture were confirmed in all patients with positive results at FAST-PLUS. Similarly, all patients with negative results for critical pubic SW (< 2.5 cm in transverse diameter) at FAST-PLUS were found to be negative at CT exam. The level of correlation between the two methods was high (Kappa value = 1) CONCLUSION: The FAST-PLUS protocol shows a high correlation with CT exam, which is the gold standard for the detection of unstable pubic SW, as well as OB pelvic injury, in polytraumatised patients. Inclusion of FAST-PLUS in patient management in the shock room may lead to a quicker identification of patients with unstable pelvis and to faster therapeutic work-up.

Contrast-enhanced ultrasonography (CEUS) in the follow-up of pediatric abdominal injuries: value and timing

AIMS

Primary aim was to investigate the value and safety of contrast-enhanced ultrasonography (CEUS) during follow-up (FU) of splenic, hepatic and renal post-traumatic injuries in a pediatric population. Secondary aim was to extrapolate appropriate timing of FU-CEUS.

METHODS

In a retrospective study, post-traumatic parenchymal injuries diagnosed with CT or CEUS, were subjected to non-operative management and followed with CEUS.

RESULTS

Forty-six patients were enrolled, with isolated or combined injuries, for a total of 30 splenic, 15 hepatic and 12 renal injuries. At admission 42/46 patients underwent CT and 4/46 underwent CEUS. During FU a total of 65 CEUS were performed: 16 within 72 h to check delayed active bleeding or parenchymal rupture; 24 between 5 and 10 days post admission, to pose indication to active mobilization or to discharge; 21 between 20 and 60 days post admission to document complete healing of the lesion or pose indication to discharge in most severe injuries. No complications related to CEUS were encountered.

CONCLUSIONS

CEUS is valuable and safe to follow patients with post-traumatic abdominal injuries, even if further data are needed for renal injuries. We propose a tailored approach based on injury grade and clinical course: in the first 3 days only in case of delayed bleeding or rupture suspect; between 5 and 10 days post trauma to ensure a safe active mobilization and/or pose indication to discharge, and over 20-30 days post trauma to pose indication to discharge in most severe injuries or document complete healing and permit return to sport activities.

A rare case of non-traumatic intrasplenic pseudoaneurysms in a patient with acute T-cell lymphoblastic leukemia

Pseudoaneurysm (PSA) or false aneurysm is a vascular lesion resulting from a focal and incomplete rupture of the arterial wall (intimate and/or elastic lamina), that allows blood to escape into the arterial wall; this small contained break causes a contained collection of blood and the creation of a "new" less resistant vessel wall, consisting of adventitia and perivascular tissues. Intrasplenic pseudoaneurysms are rare and more frequently recognize traumatic origin, sometimes are also unexpected lesions due to non-recent trauma. In contrast, non-traumatic intrasplenic pseudoaneurysms are rare complications usually due to splenic infarction, infiltration by malignant systemic disorders, infectious process, chronic pancreatitis, and arteritis. Both traumatic and non-traumatic PSA are potentially life threatening, known to cause spontaneous rupture of the spleen with massive hemoperitoneum. Contrast-enhanced CT is the gold standard technique to detect splenic PSA; however, it is important to know how to recognize it also with other imaging methods such as with ultrasound (US) and contrast-enhanced ultrasound (CEUS). US and CEUS can be often the first-line diagnostic techniques and allow to detect these lesions; they are also very useful in the follow-up. Our case report can be a reminder of the utility of the US and CEUS in detecting splenic pseudoaneurysms, which are potentially a life-threatening complication; we also recall the semiotics of these lesions with baseline ultrasound (US), color Doppler US and contrast-enhanced ultrasound (CEUS). Then, we highlight the role of contrast-enhanced CT in confirming the diagnosis and we report about the diagnostic and therapeutic value of angiography. We have to think about the possibility of a pseudoaneurysm even in the absence of a recent trauma, associated with other conditions such as a lymphoproliferative disease.

Diagnostic value of contrast-enhanced ultrasound (CEUS) and comparison with color Doppler ultrasound and magnetic resonance in a case of scrotal trauma

Intratesticular hematoma is one of the most frequent presentations of scrotal trauma. Ultrasound is the first-line imaging modality in the evaluation of scrotal trauma, and its findings are crucial for the choice of treatment. An intratesticular hematoma may represent a diagnostic pitfall for the investigating physician since its appearance may mimic other conditions, such as testicular neoplasms or segmental infarction. Although the gold standard imaging modality for the characterization of a testicular lesion is contrast-enhanced magnetic resonance (MR), MR equipment is not always available in an emergency department. Contrast-enhanced ultrasound (CEUS) may represent a valid and cheaper alternative compared with MR, which may aid the physician in the differential diagnosis. We describe the case of a 19-year-old male with a scrotal trauma following a motorcycle crash. In accordance with the literature, we carried out a contrast-medium whole-body computed tomography for the evaluation of any potential traumatic injury. Because of scrotal swelling and the patient complaining about pain in the right testicle, we performed a scrotal ultrasound, which demonstrated an enlarged right testicle, with an inhomogeneous echostructure due to the presence of a hypoechoic area in the middle and upper portion of the testicle. Color Doppler ultrasound did not show signals of intralesional vascularization. The lesion, although having characteristics compatible with hematoma, must not be diagnosed as testicular neoplasia, segmental infarction, or other mimics. For more information, a CEUS examination was performed. The examination clearly showed the extent of the lesion, the integrity of the testicular capsule, and the absence of internal vascularization; all these findings were regarded as indicators of a testicular hematoma. After the urological examination, the patient was prescribed antibiotic therapy and bed rest. For further confirmation of the CEUS examination, an MR was performed 2 days later, showing a perfect correspondence with the CEUS findings. Our case demonstrates that CEUS is a faster, cheaper, and valid alternative to MR in an emergency setting, as in testicular trauma, in which the hematoma may mimic conditions (neoplasm) that require a different treatment.
