Ventriculoperitoneal (VP) shunts complications are most often divided into 2 broad categories: mechanical failure and infection. We report a case of a migrated VP shunt with subsequent development of a pseudocyst around the patient's breast implant, a rare complication. We review the literature of VP shunt complications, including the increasing number of reported breast-related complications, and discuss proposed mechanisms by which migration may occur. With the increase in patients with breast augmentation procedures, there is potential for an increase in the number of reported cases of VP shunt migration...

Although large bowel obstruction is a common surgical emergency, its occurrence due to bladder distension is rarely reported in the literature. We report a case of large bowel obstruction caused by bladder distention secondary to benign prostate hyperplasia in a 67-year-old man. This case demonstrates a grossly distended urinary bladder compressing the rectosigmoid colon against the sacrum, presenting as a complete large bowel obstruction. Management consisted of transurethral urinary catheter insertion, which resulted in complete resolution of the bowel obstruction with drainage of a large amount of urine...

We present a young man with a background Human Immunodeficiency virus (HIV) who presented with bilateral knee pain and reduced mobility. Subsequent imaging of the knees demonstrated florid osteonecrosis (ON), which was managed conservatively. ON is seen more commonly in HIV patients than the general population, however the underlying mechanism for this association is remains unclear. An awareness of this disease is imperative to appropriately identify and manage such patients.

Synovial sarcoma typically presents as periarticular soft tissue mass in adolescent and young adult patients. Very rarely, soft tissue sarcomas may arise primarily within bone posing a significant diagnostic challenge as primary osseous malignancies such as osteosarcoma and metastatic disease are much more common. While tissue sampling with immunohistochemical and genetic testing are required for definitive diagnosis, radiologists and orthopedic oncologists should consider alternate etiologies when typical imaging features of more common bone tumors are not identified...

Parosteal osteosarcoma originates on the surface of long bones. The juxtacortical variety is one of the most common ones and accounts for about 5% of all osteosarcomas. We report the case of a 34-year-old female patient with a rare variant of parosteal osteosarcoma. Because of the less aggressive biological behavior, it is important to know it, in order to recognize and differentiate it from benign osseous lesions.

Hepatic artery aneurysms are rare and sometimes life-threating. Various treatments for hepatic artery aneurysms, including surgical and endovascular techniques are present. Here, we report the case of a 68-year-old woman who presented with an about 9 cm of common hepatic artery aneurysm detected during a routine medical checkup; she did not exhibit any symptoms. We successfully treated the aneurysm with transcatheter arterial embolization with isolation technique via pancreatic duodenal arcade.

Actinomycosis of the tongue is rare. It may be difficult to differentiate this infection clinically and radiologically from other tongue pathology especially neoplasia. We report a substantial tongue lesion which mimicked malignancy at presentation. The patient was treated successfully with 4 weeks of oral antibiotic therapy. It is also important that clinicians are aware of the radiological differential diagnosis of lingual actinomycosis.

Osteochondromas are bone exostoses, with the vast majority extending from the metaphyseal region of long bones and are capped by cartilage. A review of the current literature reveals spontaneous regression of osteochondromas is a rarely documented event, with all but two of these recorded events resolving before skeletal maturity and within 6 years of identification. We present a case of trauma-induced resolution of a solitary osteochondroma after less than 3 months in a 15-month-old male, with a review of current literature...

A 77-year-old man was transferred to our hospital for endoscopically uncontrollable active bleeding from a duodenal ulcer. Soon after his arrival, he became hemodynamically unstable and resuscitative endovascular balloon occlusion of the aorta was performed using a 7-F aortic occlusion balloon catheter (Rescue Balloon; Tokai Medical Products, Aichi, Japan). He became hemodynamically stable and was transferred to the CT room. CT demonstrated that the distal part of the catheter shaft had made a loop in the aorta and the balloon was located at the level of the upper abdomen...

Advances in oncologic treatment have improved survival rates, allowing late effects of radiotherapy to become more prevalent. Our patient, an 82-year-old woman with a remote history of right thigh basal cell carcinoma treated with resection and radiation therapy 18 years prior, presented with severe right thigh pain and inability to bear weight as she had suffered a femur fracture after a fall from standing. Initial imaging was suspicious for pathologic fracture secondary to malignancy due to imaging findings and because radiation-induced fractures have rarely been reported beyond 44 months from treatment...

We describe serial MR-spectroscopy studies in a patient with systemic lupus erythematosus and headache. We used MR-spectroscopy to monitor disease activity during periods with and without headache. MR-spectroscopy investigates metabolic alterations and was used to explore the pathophysiological mechanism involved in the complications of systemic lupus erythematosus. Our patient underwent serial conventional MRI and MR-spectroscopy at times of controlled and uncontrolled headache, with or without visual aura...

Intestinal hypoganglionosis or isolated hypoganglionosis is a rare entity with a clinical and radiologic presentation that can mimic Hirschsprung's disease in the neonatal period. The diagnosis of this entity can be challenging with suction rectal biopsies that are standard for diagnosing Hirschsprung's disease. We present this case of congenital intestinal hypoganglionosis detailing the neonatal course, due to its rarity and the conundrums faced before an eventual diagnosis could be rendered. This case also illustrates the role of full thickness rectal biopsy in selected cases such as ours where the radiologic features are typical of Hirschsprung's, despite negative suction biopsies...

Hydatid cyst disease is very rare in pregnancy having an incidence of 1 in 20,000 pregnancies and there is no recommended standard treatment. Both surgical and medical modalities have been tried. Modalities that do not use ionizing radiation such as ultrasound and magnetic resonance imaging should be preferred for diagnosis and evaluating acute conditions in a pregnant patient. In this article, a rare pelvic cyst hydatid case surrounding the uterus and MRI findings in a young pregnant patient who was coincidentally determined is represented...

Shone syndrome was first described in 1963 by Dr JD Shone. It is a constellation of congenital abnormalities compromising approximately 0.6% of all cases of congenital cardiac abnormalities. Shone syndrome is also known as Shone complex, involving several characteristic cardiac abnormalities: coarctation of the aorta, subaortic stenosis, supravalvular mitral ring, and a parachute mitral valve. Given the uncommon nature of the disease, we present this case to illustrate potential postsurgical appearances of Shone syndrome, specifically on computed tomography imaging...

Ewing sarcoma of the cervical spine is a rare diagnosis. Early recognition and treatment of this condition improves survival. Reported is a case of a 20-year-old male patient who presented with increasing neck pain. Computed tomography and magnetic resonance imaging showed a mass with a primary differential diagnosis of Ewing sarcoma. As a result of mass effect and spinal cord compression, immediate medical intervention was deemed necessary to prevent neurologic deficits.

The objective of this study was to describe a case of marked hypoplasia of the right renal vein with drainage into ipsilateral gonadal vein. A 66-year-old man, known for hypertension and previous smoking, underwent an abdominal ultrasound exam, which detected a juxtarenal aortic aneurysm. Computed tomography scan confirmed the presence of the aortic aneurysm; furthermore it showed an abnormal right kidney venous drainage consistent in a dilated and tortuous vein, which originated at the hilar region, heading caudally and joining the right spermatic vein at level of aortic carrefour...

Acute superior mesenteric vein thrombosis was first described in 1935 by Warren and Eberhardt. It is a potentially life-threatening condition, as it can lead to bowel ischemia and, ultimately, infarction. Its etiology may be primary or secondary to acquired prothrombotic conditions. Early recognition of mesenteric venous thrombosis is important, but can be challenging due to its nonspecific clinical presentation. Contrast-enhanced computed tomography is currently the gold standard for diagnosis. Systemic anticoagulation and surgical resection of the necrotic segment are the two main treatments...

For percutaneous minimally-invasive local ablation therapies of malignant lesions within the liver computed tomography (CT) fluoroscopy or ultrasound (US) can be applied for the positioning of ablation probes. However, lesions in liver segment I and in the upper part of liver segment VIII are difficult to reach with CT fluoroscopy and US guidance even for experienced interventionalists as steep and transcostal access paths may be needed. In addition, there is always the risk to lacerate crucial vessels near the liver hilus...

Eagle's syndrome (ES) refers to symptomatic elongation of the ossified styloid process. A styloid process greater than 2.5 cm in length should be considered abnormal; however, an elongated styloid process is not sufficient for a diagnosis of ES; only an abnormal styloid process in association with symptoms can confirm the syndrome. In this case report, we discuss a 54-year-old man who has come to our attention with various symptoms: dysphagia to both solids and liquids, difficulty swallowing, neck pain, and a foreign body sensation during bilateral neck rotation and mouth opening...

Patients with hemophilia suffer from repeated episodes of hemarthrosis leading to chronic inflammation and synovitis. Radiosynovectomy is an effective nonsurgical modality that can reduce inflammation, pain, and hemarthrosis in such cases. We describe an adolescent male with severe Hemophilia A, who developed arterial vasculitis and perivasculitis targeting the brachiocephalic, right common carotid, and right subclabvian arteries occurring within few days after difficult Phosphorus-32 radiosynovectomy, possibly as a complication of the procedure...
