Imaging of seminal vesicles: a pictorial review.

The seminal vesicles are frequently overlooked when reviewing abdominal and pelvic imaging studies, and normal variants and pathologic conditions are often missed or misinterpreted. This is largely due to lack of familiarity with the organ, its anatomic variants, congenital abnormalities and disease conditions. This pictorial review aims to familiarize the reader with the range of normal appearances, congenital anomalies and disease entities that involve the seminal vesicles to avoid overtreatment and misdiagnoses.

Port-a-Cath fracture and migration in paediatric cancer patients: incidence and management at a tertiary care centre - a 15-year experience.

Introduction: Port-a-Cath or chemoport provides prolonged central venous access for cancer patients requiring prolonged chemotherapy. Prolonged use of chemoport is associated with many complications. Dislodgement and migration of chemoport catheter is a rare and reportable complication with potentially serious consequences.

Infantile myofibromatosis: review of imaging findings and emphasis on correlation between MRI and histopathological findings.

Background: Infantile myofibromatosis (IM) is the most common fibrous tumor of infancy. MRI is considered the gold standard in IM evaluation. Very little has been published about IM with histopathology correlation in the pediatric age.

Trans-Catheter Aspiration of Systemic Air Embolism Causing Cardiac Compromise During CT-Guided Lung Biopsy, a Potentially Lifesaving Maneuver.

Systemic artery embolism is a rare complication of CT-guided lung biopsy. Immediate clinical and radiological recognitions are crucial for rapid intervention and prevention of fatal outcome. Although hyperbaric oxygen is the suggested treatment of mildly symptomatic systemic artery embolization, aspiration of air should be considered as part of the management in cases of cardiac arrest.

Pancreaticoduodenal Artery Aneurysm Associated with Celiac Trunk Stenosis: Case Illustration and Literature Review.

Pancreaticoduodenal artery aneurysms (PDA) are rare visceral aneurysms. Celiac trunk stenosis represents a common attributable aetiology for those aneurysms. Therefore, an alternative treatment approach, which differs from those isolated aneurysms, is recommended.

Preoperative Localization of Mediastinal Parathyroid Adenoma with Intra-arterial Methylene Blue.

Ectopic parathyroid is found in 16% of patients with hyperparathyroidism. 2% of ectopic parathyroid adenomas are not accessible to standard cervical excision. In such cases, video-assisted thoracoscopic resection is the recommended definitive treatment.

Median Arcuate Ligament Syndrome: A Single-Center Experience with 23 Patients.

Background: Median arcuate ligament syndrome (MALS) is a rare entity that occurs when the median arcuate ligament of the diaphragm is low-lying, causing a compression to the underlying celiac trunk. We reviewed the vascular changes associated with MALS in an effort to emphasize the seriousness of this disease and the complications that may result.

Methods: This is a retrospective descriptive analysis of 23 consecutive patients diagnosed with MALS between January 1, 2012 and December 31, 2015 at a tertiary medical center.

Image-guided ureteral reconstruction using rendezvous technique for complex ureteric transection after gunshot injuries.

Management of complex ureteric transection poses a significant clinical challenge, particularly after gunshot injuries due to marked distortion of anatomy and associated tissue loss. We report two cases of total ureteric transection due to gunshot injury successfully repaired using fluoroscopy-guided rendezvous procedure and double J stent placement. This minimally invasive approach may offer a safe and effective technique to repair complete ureteral transection and obviate the need for complex surgical procedures.

Patient Evaluation and Preparation in Vascular and Interventional Radiology: What Every Interventional Radiologist Should Know (Part 2: Patient Preparation and Medications).

Performing an interventional procedure imposes a commitment on interventional radiologists to conduct the initial patient assessment, determine the best course of therapy, and provide long-term care. Patient care before and after an interventional procedure, identification, and management of early and delayed complications of various procedures are equal in importance to the procedure itself. In this second part, we complete the comprehensive, methodical review of pre-procedural care and patient preparation before vascular and interventional radiology procedures.

Patient Evaluation and Preparation in Vascular and Interventional Radiology: What Every Interventional Radiologist Should Know (Part 1: Patient Assessment and Laboratory Tests).

Performing an interventional procedure imposes a commitment on interventional radiologists to conduct the initial patient assessment, determine the best course of therapy, and provide long-term care after the procedure is completed. After patient referral, contact with the referring physician and multidisciplinary team approach is vital. In addition, clinical history, physical examination, as well as full understanding of the pre-procedural laboratory results and imaging findings can guide the interventional radiologist to implement the most appropriate management plan, avoid unnecessary procedures, and prevent complications to achieve a successful outcome.

Assessment of surgical portosystemic shunts and associated complications: The diagnostic and therapeutic role of radiologists.

Surgical portosystemic shunting, the formation of a vascular connection between the portal and systemic venous circulation, has been used as a treatment to reduce portal venous pressure. Although the use of portosystemic shunt surgery in the management of portal hypertension has declined during the past decade in favour of alternative therapies, and subsequently surgeons and radiologists became less familiar with the procedure, it remains a well-established treatment. Knowledge of different types of surgical portosystemic shunts, their pathophysiology and complications will help radiologists improve communication with surgeons and enhance their understanding of the diagnostic and therapeutic role of radiology in the assessment and management of these shunts.

Admission privileges and clinical responsibilities for interventional radiologists.

Although clinical involvement by interventional radiologists in the care of their patients was advocated at the inception of the specialty, the change into the clinical paradigm has been slow and patchy for reasons related to pattern of practice, financial remuneration or absence of training. The case for the value of clinical responsibilities has been made in a number of publications and the consequences of not doing so have been manifest in the erosion of the role of the interventional radiologists particularly in the fields of peripheral vascular and neuro intervention. With the recent recognition of interventional radiology (IR) as a primary specialty in the USA and the formation of IR division in the Union of European Medical Specialists and subsequent recognition of the subspecialty in many European countries, it is appropriate to relook at the issue and emphasize the need for measures to promote the clinical role of the interventional radiologist.

Posterior dislocation of a discoid meniscus in a child: a case report.

Discoid meniscus of the knee is a well-known anatomic and congenital variant of the lateral meniscus. It is often asymptomatic, but can be associated with knee pain and other symptoms. Posterior dislocation of the discoid meniscus is an extremely rare finding; to the best of our knowledge, only one case has been reported in the literature.

Isolated hepatic artery injury in blunt abdominal trauma presenting as upper gastrointestinal bleeding: treatment with transcatheter embolisation.

Liver injury in blunt abdominal trauma is common. However, not often does blunt trauma cause injury to the anatomical structures of the porta hepatis. Isolated injury of the hepatic artery has been rarely reported in the literature.

Popliteal artery entrapment presenting as acute limb ischemia: treatment with intra-arterial thrombolysis. Case report and review of the literature.

Popliteal artery entrapment syndrome (PAES) is a relatively rare condition, which occurs predominantly in active young adults who lack atherogenic risk factors. It has been rarely reported in patients under the age of 18 years. The most common presentation in the early stages is intermittent claudication; however, in the later stages of undiagnosed PAES, acute ischemia can occur as a result of complete arterial occlusion or embolism.

Unusual arterial pattern of the gastrointestinal tract: inferior mesenteric artery arising from the iliac artery and corkscrew external iliac.

Anatomical variations of the digestive system arteries are important due to their clinical significance. However, anomalies in the inferior mesenteric artery (IMA) are the least common compared with the celiac trunk and superior mesenteric artery. This report describes the case of a 67-year-old man with an extremely rare variant in which the IMA arises from the left common iliac artery, and the ipsilateral external iliac artery has a corkscrew pattern.

Bone marrow mesenchymal stem cell transplantation in patients with multiple sclerosis: a pilot study.

We explore the safety, and therapeutic benefit of intrathecal injection of ex-vivo expanded autologous bone marrow derived mesenchymal stem cells (BM-MSCs) in 10 patients with advanced multiple sclerosis (MS). Patients were assessed at 3, 6 and 12 months. Assessment at 3-6 months revealed Expanded Disability Scale Score (EDSS) improvement in 5/7, stabilization in 1/7, and worsening in 1/7 patients.

Catheter fracture and migration into the coronary sinus--an unusual migration site: case report and review.

Catheter fracture and cardiac migration are rare but known complications. Most reported cases have developed between the clavicle and the first rib as a consequence of catheter pinching between these two bony structures. To our knowledge, this is the first reported case of catheter migration into the coronary sinus.

Venous sinus thrombosis leading to stroke in a patient with sickle cell disease on hydroxyurea and high hemoglobin levels: treatment with thrombolysis.

A 21-year-old man with homozygous sickle cell disease maintained on hydroxyurea for 1 year developed thrombosis of the superior sagittal, right transverse, and right sigmoid dural sinuses with a large venous infarct. He was successfully treated with endovascular thrombolysis. Investigation did not reveal any inherited or acquired hypercoagulable state.
