We describe a case of a 65-year-old woman affected by hemangiopericytoma/solitary fibrous tumor of the right shoulder-subclavian region. Hemangiopericytoma/solitary fibrous tumor is a rare tumor of uncertain malignancy. She reports shoulder pain and inability to abduct the arm and elevate the shoulder. Imaging showed erosion of the scapula. The patient underwent 5 sessions of "on demand" embolization in the previous 2 years scheduled for recurrence of symptoms-swelling of tissues. Further 2 treatments were achieved through embolization via 2 different microballoon catheter combined with percutaneous cryoablation with 5 probes. Images after the treatment demonstrate a marked reduction in the hypervascularized area and an increase in the necrosis area. So, this combined treatment is safety and reproducible also in extrahepatic tissue., (© 2023 The Authors.)

In this paper, we describe a rare case of coronary artery aneurysms occasionally found on a pre interventional Coronary Computed Tomography Angiography performed on a 67-year-old man with a history of aneurysm of the ascending aorta previously treated with Bentall surgery, who arrived at our hospital to have a percutaneous valve-in-valve implantation procedure. Even though the patient was considered not eligible for the procedure, due to his many comorbidities, and conservatively managed, at 1-year followup his angiographic condition remained stable., (© 2021 The Authors.

Right aortic arch with mirror image branching (RAMI) is a rare congenital defect of the aorta. The exact incidence of RAMI in the general population is unclear. In RAMI the first branch arising from the arch is the left innominate artery, followed by the right carotid artery and right subclavian arteries. We report a case of an adult female patient with RAMI discovered as an incidental finding during radiological investigations for suspected pulmonary embolism in emergency department. No other congenital malformations were reported. It is important to recognize congenital variants of the aortic arch, as they can have relevant implications for patients' prognosis and management. Therefore, being aware of these conditions is key to avoid any mistakes or surgical and endovascular complications., Competing Interests: The authors have declared that no competing interests exist.

Renal artery stenosis commonly manifests with hypertension refractory to medical treatment. We report a case of renal artery stenosis occurring in a 19-year-old female patient who presented with extremely high blood pressure and bilateral renal stenosis at the duplex ultrasound. Renal angiography confirmed the bilateral and irregular stenosis due to fibromuscular dysplasia, associated to extent collaterals suppling the poststenotic right renal artery. Therefore, angioplasty with drug-eluting balloon was performed in order to obtain a good vessel patency and to improve patency in the long term follow-up. After the endovascular treatment the blood pressure improved markedly, maintaining this result at 12 months follow-up at clinical examination and duplex ultrasound.

We reported the cases of two adult male patients who were admitted to our emergency room with abdominal pain and dyspnea caused by gallstones and pulmonary embolism respectively. During the radiological investigations, as collateral findings, we found two anomalous development of the inferior vena cava. These conditions affect about 4% of population and, although asymptomatic or mildly symptomatic, are associated with thrombotic manifestations as deep vein thrombosis and pulmonary embolism. The prompt recognition of these anomalies is necessary in order to prevent the complications associated with these conditions and to set the best therapy for patients.
