INTRODUCTION: The use of novel bioengineer treatment techniques such as Autologous Tenocyte Implantation (ATI) have shown promising improvements in both pain ratings and functional outcomes in elbow, gluteal and shoulder tendon pathology. This case will review the injury timeline of ATI intervention in an elite male swimmer with subscapularis tendon pathology and investigate whether ATI has a concomitant healing effect associated with improved functional outcomes. METHODS: A palmaris longus tendon biopsy was performed and cells were expanded by in-vitro culture...

An aorto-oesophageal fistula is a rare, life-threatening complication caused by sharp foreign bodies in the oesophagus. We report an aorto-oesophageal fistula in the inferior segment of thoracic oesophagus caused by a fish bone. Multiplanar reconstruction of computed tomography and computed tomography angiography demonstrated that a foreign body had pierced from the left posterior wall of the oesophagus into the descending aortic wall. These computed tomography images can help radiologists make the correct diagnosis and provide precise evidence for clinicians to perform a timely surgical intervention...

BACKGROUND: Metastases to the bone are common in cancer patients, and it has been estimated that up to 50% of patients with pelvic bone metastases will not achieve adequate pain control with medications alone. This has led to a paradigm shift over recent years towards the use and development of minimally invasive image-guided treatment options for palliation of bony metastases. Despite these developments, large metastatic lesions are still often considered to be "hopeless cases" that would garner little to no benefit from image-guided intervention...

PURPOSE: To evaluate parameters that influence the amount of movement of peripherally inserted central catheter (PICC) tips regarding upper limb movement. METHODS: In a prospective 12-month observational study, 200 PICCs were implanted in 162 patients (mean age 56.8 ± 15.2 years) by interventional radiologists into the basilic vein of the mid-aspect of the upper arm. Three PICC tip positions were documented with a chest x-ray: patient supine with an abducted (90°), an adducted arm, and in an upright position with an adducted arm...

Cesarean scar pregnancy (CSP) is a rare type of ectopic pregnancy. It is becoming more common, but it can lead to uterine rupture and severe hemorrhage. Here, we report a case of a 37-year-old woman with CSP complicated with pseudoaneurysm. The pseudoaneurysm emerged following focal injection of methotrexate (MTX) and potassium chloride with systemic MTX treatment. Due to a risk of sudden bleeding, uterine artery embolization (UAE) was recommended, but the patient hoped to avoid this if possible. Because the serum human chorionic gonadotropin level and the gestational sac were still persistent, dilation and curettage were performed with interventional radiologists on standby...

This case study reports the diagnosis and treatment of a lower limb venous ulcer with abnormal underlying venous pathology. One male patient presented with bilateral varicose veins and a right lower limb ulcer. Upon investigation, full-leg duplex ultrasonography revealed total incompetence of the great saphenous vein in the left leg. In the right leg, duplex ultrasonography showed proximal incompetence of the small saphenous vein, and dilation of the anterior accessory saphenous vein, which remained competent...

BACKGROUND: Intraductal tubulopapillary neoplasm (ITPN) depicts a distinct entity in the subgroup of premalignant epithelial tumors of the pancreas. Although the histomorphological and immunophenotypical characterization of ITPN has been described by several authors in terms of report of case series in the past, the rarity of that tumor subtype and similarity to other entities still makes identification of ITPN a challenge for radiologists and pathologists. To date, little is known about tubulopapillary carcinoma that can evolve from ITPN...

The transfemoral arterial approach is used to gain access for angiography, percutaneous coronary interventions, or various endovascular therapies. To decrease the risk of procedure-related vascular complications, it is recommended to puncture the common femoral artery in its middle segment. However, due to inadequate access or anatomical variability, various complications, including hematoma, pseudoaneurysm, arteriovenous fistula, thrombosis, or dissection, can occur after transfemoral arterial interventions...

Severe pelvic trauma is a challenging condition. The pelvis can create multifocal hemorrhage that is not easily compressible nor managed by traditional surgical methods such as tying off a blood vessel or removing an organ. Its treatment often requires reapproximation of bony structures, damage control resuscitation, assessment for associated injuries, and triage of investigations, as well as multimodality hemorrhage control (external fixation, preperitoneal packing, angioembolization, REBOA [resuscitative endovascular balloon occlusion of the aorta]) by multidisciplinary trauma specialists (general surgeons, orthopedic surgeons, endovascular surgeons/interventional radiologists)...

The pulmonary veins carry oxygenated blood from the lungs to the heart, but their importance to the radiologist extends far beyond this seemingly straightforward function. The anatomy of the pulmonary veins is variable among patients, with several noteworthy variant and anomalous patterns, including supernumerary pulmonary veins, a common ostium, anomalous pulmonary venous return, and levoatriocardinal veins. Differences in pulmonary vein anatomy and the presence of variant or anomalous anatomy can be of critical importance, especially for preoperative planning of pulmonary and cardiac surgery...

The Liver Imaging Reporting and Data System (LI-RADS) is a reporting system created for the standardized interpretation of liver imaging findings in patients who are at risk for hepatocellular carcinoma (HCC). This system was developed with the cooperative and ongoing efforts of an American College of Radiology-supported committee of diagnostic radiologists with expertise in liver imaging and valuable input from hepatobiliary surgeons, hepatologists, hepatopathologists, and interventional radiologists. In this article, the 2017 version of LI-RADS for computed tomography and magnetic resonance imaging is reviewed...

OBJECTIVES: Congenital renal arteriovenous malformations (rAVMs) represent rare vascular diseases. The heterogeneous vascular architecture of each rAVM determines the endovascular treatment techniques employed. We reported our experience with the endovascular treatment of a series of rAVMs. MATERIALS: This retrospective study consisted of 12 patients with 12 rAVMs who underwent renal arterial embolization (RAE) in our hospital. Embolic materials, including particles, liquid embolic agents (n-butyl 2-cyanoacrylate, Onyx, and ethanol), and coils, were selectively used based on the decisions of interventional radiologists...

BACKGROUND: Indwelling Foley catheter is a rare cause of urinary bladder perforation, a serious injury with high mortality that demands accurate and prompt diagnosis. While the gold standard for diagnosis of bladder injury is computed tomography (CT) cystography, few bladder ruptures associated with Foley catheter have been reported to be diagnosed in the emergency department (ED). CASE REPORT: An 83-year-old man with indwelling Foley catheter presented to the ED for hematuria and altered mental status...

PURPOSE: In women, the uterine artery is the main branch of the internal iliac artery, vascularizing most of the uterus. Knowledge of its origin and variations is essential during extensive gynaecological surgery and interventional radiological procedures. We aimed to investigate its origin and explore its anatomical variations by three-dimensional (3D) reconstructed computed tomography (CT) angiography. METHODS: This was a retrospective, monocentric observational study involving CT scans of the abdomen and lower limbs of women < 50 years old with 3D reconstructed CT images of the internal and external iliac arterial axes...

Introduction Pleural effusion is the excess fluid that accumulates in the pleural space. Pneumothorax is the collection of free air in the pleural cavity, while empyema is the collection of pus in the pleural cavity. Such pleural pathologies pose a great challenge to patients and health care professionals alike. While multiple management options exist, the major portion of it is carried out in the inpatient setting. We sought to evaluate the ambulatory use of indwelling pleural catheters for pleural pathologies, including malignant pleural effusion, empyema, and primary spontaneous pneumothorax...
