Ischaemic Stroke Occurring in a Patient Treated with Monoclonal Antibodies for COVID-19.

Since the COVID-19 outbreak began, an association between COVID-19 and thrombotic diseases has been underlined. Although this association is more frequent with venous thromboembolism, ischaemic stroke has also been reported as a thrombotic complication in several cohorts of affected patients. Furthermore, the association between ischaemic stroke and COVID-19 has been considered a risk factor for early mortality.

A rare case of a spontaneous abscess of the corpus cavernosum: the role of contrast-enhanced ultrasound in diagnosis and post-therapeutic follow-up.

In this paper, we describe the pattern of an idiopathic corpus cavernosum (CC) abscess using contrast-enhanced ultrasound (CEUS) and compare this to the lesion characterization achieved using preliminary baseline ultrasound/color doppler (ECD). In a 43-year-old man, who arrived at our emergency department for a penile swelling and hematopyuria, ECD examination showed equivocal mucosal and subcutaneous tissue swelling, an inhomogeneous hypoechoic area in the left CC, and a suspected millimetric interruption of the albuginea. CEUS showed multiple avascular areas wrapped in a hyperperfused rim representing abscesses and a not-perfused balanopreputial-oriented fistula.

Real-time contrast-enhanced specific ultrasound in staging and follow-up of splenic lymphomas.

From January 2003 to April 2005 we studied 25 lymphoma patients (10 with HD, 4 with low-grade NHL, 6 with high-grade NHL and 5 with chronic lymphatic leukaemia; 14 men, 11 women, age range 28-79 years). After a baseline US study we rapidly injected 4.8 mL of the second-generation microbubble contrast agent SonoVue (Bracco, Italy).

Real-time harmonic contrast material-specific US of focal liver lesions.

Recent advances in contrast material-enhanced ultrasonography (US) mainly include (a) development of low-acoustic-pressure (low-mechanical-index) harmonic software, capable of obtaining real-time images without disrupting contrast material microbubbles, and (b) commercialization of new contrast media ("second-generation" contrast media), capable of producing intense echo signals in this low-mechanical-index setting. With use of low-mechanical-index continuous-mode contrast-enhanced US, the circulatory kinetic models of various focal liver lesions can be displayed dynamically. Hepatic lesions usually have typical perfusion characteristics and enhancement patterns through the various phases of parenchymal enhancement, which helps characterize lesions and, in most cases, allows definitive diagnosis, even among lesions that exhibit very similar baseline appearances.

Blunt hepatic trauma: evaluation with contrast-enhanced sonography: sonographic findings and clinical application.

Objective: The purpose of this study was to report our initial experience in the assessment of liver trauma with real-time contrast-enhanced sonography (CES).

Methods: From January 2000 to December 2003, there were 431 hemodynamically stable patients evaluated with sonography for blunt abdominal trauma. Among these patients, 87 were selected to undergo second-level imaging, consisting of CES and computed tomographic (CT) evaluation.

Real-time, contrast-enhanced sonographic imaging in emergency radiology.

Purpose: To report our pilot experience in the evaluation of traumatic and nontraumatic emergencies with contrast-specific, continuous-mode sonography (US) and a second-generation contrast medium.

Materials And Methods: Between January 2002 and December 2003 we evaluated 126 acute patients by using real-time contrast-specific US: blunt abdominal trauma (76 cases), penetrating abdominal trauma (3), blunt scrotal trauma (1), right upper abdominal pain (10), left upper abdominal pain (9), epigastric pain (2), flank pain (5), right lower abdominal pain (2), scrotal pain (7), postoperative abdominal sepsis (1), post-biopsy haemorrhage (1), ruptured abdominal aortic aneurysm (8), postsurgical aortic bleeding (1). In all cases the radiologist performed a complete baseline US survey and then decided whether or not to add a contrast-enhanced examination.

Contrast-enhanced sonography for diagnosis of ruptured abdominal aortic aneurysm.

Objective: We describe the contrast-specific sonography features of ruptured abdominal aortic aneurysm, and we hypothesize that this technique would be useful for emergency imaging of patients with suspected aneurysm rupture.

Conclusion: We used contrast-specific sonography to assess eight patients with ruptured abdominal aortic aneurysm. Five of these cases were correlated with CT findings.

Real-time contrast-enhanced ultrasound of the spleen: examination technique and preliminary clinical experience.

Purpose: To report our preliminary experience in the evaluation of the spleen using a real-time contrast-specific ultrasound module in combination with a second-generation contrast agent.

Materials And Methods: In a 7-month period, 55 patients (34 males and 21 females, aged 5-77 years) with spleen disorders were evaluated by means of contrast-enhanced ultrasound. Two patients were studied because of baseline evidence of an accessory spleen and both underwent ultrasound follow-up.

Splenic trauma: evaluation with contrast-specific sonography and a second-generation contrast medium: preliminary experience.

Objective: To report our experience in the assessment of splenic trauma with contrast-coded sonography and a second-generation contrast medium.

Methods: From January to May 2002, 120 patients were studied with sonography for suspected splenic trauma. Twenty-five were selected for further imaging because of sonographic findings positive for splenic injury, findings positive for peritoneal fluid only, indeterminate findings, and negative findings with high clinical or laboratory suspicion.
