“…A few reasons can be considered: hypoenhancement may indicate perfused solid splenic lesions of tissue devoid of sinusoids 19 and lower microbubble uptake in hypoechoic splenic hemangiomas. 1,10,16,17 Taibbi et al 37 reported that 8 of 27 hemangiomas showed some degree of enhancement on CEUS but remained substantially lower than that of the surrounding splenic tissue. Stang et al 19 reported that the most apparent overlap between benign and malignant splenic lesions was seen with nodular sarcoidosis and lymphoma, both of which were characterized by multiple progressive hypo-enhanced lesions up to 3 cm in diameter.…”

Purpose To identify and validate contrast-enhanced ultrasound (CEUS) features for differentiating malignant from benign splenic lesions. Patients and Methods Splenic lesions in 123 patients who underwent conventional ultrasound (B-mode US) and CEUS were included in this study. Two radiologists evaluated the sonograms of B-mode and CEUS. Statistical analysis was performed to identify significant imaging predictors for splenic malignant lesions. Two other radiologists independently reviewed B-mode and CEUS sonograms and diagnosed the lesions based on proposed criteria as 1) benign, 2) probably benign, 3) probably malignant or 4) malignant. The diagnostic efficiency between B-mode US and CEUS was compared. Results Common imaging findings of malignant lesions included hypoechoic, ill-defined margin, absence of cystic/necrotic portion, presence of splenomegaly on B-mode US, and hypoenhancement, rapid washout and presence of intralesional vessels on CEUS ( P < 0.05). Among them, three independent features were identified using multivariate logistic regression analysis: hypoechoic pattern, hypoenhancement pattern and intralesional vessels. When three of these findings were combined as a predictor for splenic malignant lesions, 22 (55.0%) of 40 malignant splenic lesions were identified with a specificity of 100%. The diagnostic performance of two readers using receiver operating characteristic curve analysis was 0.622 and 0.533, respectively, for B-mode US, which was significantly improved to 0.908 and 0.906 for CEUS ( P < 0.001). The degree of other diagnostic efficiency and inter-reader agreement also increased with CEUS compared to B-mode US. Conclusion CEUS may provide more useful information than B-mode US and improve the diagnosis efficiency for distinguishing malignant from benign splenic lesions.

Rationale:Testicular capillary hemangioma (TCH) is a rare benign tumor of the testis. To the authors’ knowledge, there is currently only a few literatures describing the use of contrast-enhanced ultrasound (CEUS) to diagnose TCH. Accurate preoperative diagnosis of benign tumors can avoid orchiectomy. A case of TCH evaluated using high-frequency ultrasound and CEUS is presented.Patient concerns:A 21-year-old male presented with a right testicular mass during a routine physical examination, and was admitted to the authors’ hospital for definitive diagnosis and treatment.Diagnoses:Combined gray-scale, color Doppler ultrasonography, and CEUS did not exclude the possibility that the right testicular lesion may be a benign tumor. Combined with morphological and immunohistochemical staining results, a pathological diagnosis of TCH was considered.Interventions:The patient underwent right orchiectomy under general anesthesia, which proceeded smoothly.Outcomes:At the 12-month follow-up, the patient was completely asymptomatic and resumed all daily activities.Lessons:TCH is a rare benign tumor and lacks extensive previous data in imaging findings. If TCH can be diagnosed accurately before surgery, excessive or inappropriate treatment of benign lesions can be minimized, which will be beneficial to the physical and psychological health of patients.

“…All of the images were recorded and stored in a computer. Digital cine clips of splenic lesions were registered during arterial phase (5–30 s after injection), intermediate parenchymal phase (60–90 s after injection), and late parenchymal phase (180–300 s after injection) [ 14 ]. Compared with the surrounding splenic parenchyma, the enhancement pattern of the lesions was classified into hyper-enhancement, iso-enhancement, hypo-enhancement, and non-enhancement; the enhancement distribution pattern was classified into homogeneous enhancement, rim-like enhancement, and septation-like enhancement.…”

Background The aim of this study was to characterize the contrast-enhanced ultrasound imaging features of focal splenic tuberculosis. Material/Methods We retrospectively analyzed the conventional ultrasound (US) and contrast-enhanced ultrasound (CEUS) imaging features of 22 patients with splenic TB confirmed by surgical histopathology or biopsy. Results Conventional US demonstrated that 15 of the 22 patients had a single lesion, while 7 had multiple lesions. The maximum diameter of the lesions ranged from 1.0 to 3.7 cm. Of the 22, 17 were detected with hypoecho and 5 were detected with complex echo by conventional US. Seven (7/22) were detected with blood flow signals by color Doppler flow image (CDFI). CUES demonstrated that 18 cases (81.8%, 18/22) began to enhance in the arterial phase, mostly followed by slow wash-out in the intermediate or late parenchymal phase, and 4 (18.2%, 4/22) presented with non-enhancement during all phases. The enhancement patterns were categorized into 4 types: Type I, homogeneous enhancement (2/22); Type II, rim-like enhancement (12/22); Type III, septation-like enhancement (4/22); and Type IV, non-enhancement (4/22). Conclusions CEUS showed that splenic TB lesions were enhanced in the arterial phase, followed by slow washed out or persistent enhancement in the intermediate and late parenchymal phases. The rim- or septation-like enhancement may be helpful for diagnosing splenic TB. The splenic lesions presenting round hypoecho by conventional US and complete non-enhancement by CEUS are highly suspicious of splenic TB.
