It occurs predominantly in the second and third decade of life. The main symptoms are unilateral and scrotal as seen in more common conditions such as testicular torsion, epididymitis, orchitis, or blunt trauma. The primary testis investigation method is ultrasonography (US) with color Doppler. Normally segmental testicular infarction is seen as a round or wedge-shaped hypoechoic lesion within the testicle in combination with absent or low blood flow. In contrast, vascular testicular lesions are often malignant. However, US alone cannot rule out testicular neoplasms, since hypovascularity of testicular tumors has been described.","PeriodicalId":44852,"journal":{"name":"Ultrasound International Open","volume":"6 2","pages":"E50-E52"},"PeriodicalIF":3.2,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/a-1270-7795","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38607718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is characterized by placentomegaly with multiple cystic lesions of the stem villi and vascular anomalies (Pawoo and Heller, 2014). Early detection of PMD has been described during routine prenatal ultrasound (Vaisbuch et al., 2009). The sonographic characteristics of PMD include increased placental thickness and multiple cystic areas within the placenta with either an absence of blood flow or with low venous Doppler signals (Vaisbuch et al., 2009). The differential diagnosis of multicystic placental lesions with the presence of a live fetus include partial molar pregnancy, multiple hematomas, chorioangioma Beckwith-Wiedemann syndrome and PMD. Chorioangiomas are well circumscribed masses within the placenta and they are characterized by the presence of a single feeding vessel with the same pulse rate as the umbilical cord (Zalel et al., 2002). Invasive prenatal testing is required for the exclusion of partial molar pregnancy and Beckwith-Wiedemann Syndrome (Vaisbuch et al., 2009). Definitive diagnosis of PMD is based on the pathologic examination of the placenta. Histology reveals aneurysm or dilated blood vessels that may be thrombosed. The stem villi are edematous and enlarged with thick-walled vessels, without trophoblastic proliferation (Pawoo and Heller, 2014).

Furthermore, the immunosuppressant state of graft recipients may cause the tumor to behave more aggressively (G. Ploussard et al. BJU Int. 2012: 109: 195–9 [3]). In these complex cases, there is a need for a minimally invasive nephron-sparing treatment option that can keep patients free of dialysis. Here we present two cases of T1a renal cell carcinoma (RCC) in renal grafts that were successfully treated using ultrasound-guided percutaneous cryoablation: a minimally invasive technique where only the tumor is destroyed, and the graft’s function is preserved. Furthermore, when comparing percutaneous cryoablation to laparoscopic cryoablation and partial nephrectomy, the risk of treatment-related complications is decreased (T. Klatte et al.

Chemotherapy and radiochemotherapy are commonly performed as alternative treatments, but satisfaction with the results remains low. High intensity focused ultrasound therapy (HIFU) is expected to be a minimally invasive therapy for these cases. HIFU is an epoch-making therapeutic method and is a local therapy that converges a large number of ultrasonic transmission sources at one point at the target site of the tumor and cauterizes tissues from outside the body 1 2 3 . \u0000 \u0000Case Description \u0000A 63-year-old male, who underwent CT examination at another medical center due to epigastric pain, was then diagnosed with a low-density tumor (65mm) infiltrating the celiac artery (CA) and superior mesenteric artery (SMA) in the pancreas body ( Fig. 1a ). It was histologically diagnosed as PC (UICC criteria; stage III) by EUS-FNA. There was no suitable surgery. Therefore, chemoradiotherapy was initiated due to locally advanced PC. Chemotherapy was performed with GS therapy (GEM 1000 mg/m 2 +S-1 100 mg/day), and radiotherapy with 50.4 Gy / 28 fraction. After receiving GS therapy (GEM 1000 mg/m 2 +S-1 100 mg/day) for 2 months, the PC was still diagnosed as progressive disease (PD) based on WHO criteria by CT. The patient presented at our hospital for HIFU therapy. Under sufficient informed consent, HIFU therapy was performed as an additive therapy to systemic chemotherapy. This clinical trial was approved by the ethics committee of our hospital (IRB: 890) and registered with University Hospital Medical Information (UMIN) and was initiated (UMIN000009969). B-mode US showed a hypoechoic mass in the pancreas body ( Fig. 2a ), and contrast-enhanced ultrasound (CE-US) showed isovascularity in previous HIFU therapy ( Fig. 2b ). The FEP-BY 02 HIFU Therapeutic System was used as the HIFU device.
