" Mixed " trauma to the carotid artery in a mixed martial arts injury - A case report and review of the literature
We present the case of a mixed martial arts (MMA) cage fighter who presented to the emergency department with a right sided common carotid artery pseudoaneurysm as a result of a neck trauma at an MMA event. We discuss the management of blunt force neck trauma, differential diagnosis, imaging findings and review the literature on blunt cerebrovascular injury following blunt force injury to the neck.

Aberrant Right Vertebral Artery with a Diverticulum of Kommerell: Review of a Rare Aortic Arch Anomaly
The normal aortic arch branching pattern is of a three-vessel arch with the vertebral arteries arising from the subclavian arteries. There are a variety of well-known symptomatic and asymptomatic aortic branching patterns widely reported in the literature. An anomalous right vertebral artery with a diverticulum of Kommerell is an extremely rare variant, with few other cases reported in the literature. Herein, we review the embryology of the aortic arch and vertebral artery, the various types of Kommerell ' s diverticula and the clinical significance of this anomaly.

Pneumorrhachis after Recreational Drug Use
We report the case of a 16 year old male who presented with throat discomfort and a feeling of altered voice after recreational drug use. Examination confirmed widespread subcutaneous emphysema above the clavicles and plain radiograph and computed tomography imaging confirmed the presence of extensive pneumomediastinum and pneumorrhachis. The patient was managed conservatively and made a full recovery. The clinical and imaging feat ures of spontaneous pneumorrhachis are presented as well as a review of the literature with regard to pathogenesis, management and outcome. Knowledge and understanding of this unusual phenome...

Thrombogenic superior vena cava syndrome from long-standing central venous access in a 5-year-old patient treated with balloon-expandable stents
We present a 5-year-old male with superior vena cava syndrome associated with acute onset of severe upper extremity and facial swelling, dyspnea, and a right subclavian central venous catheter malfunction. The patient was ultimately treated with percutaneous stenting of the superior vena cava with balloon-expandable Palmaz stents following unsuccessful angioplasty, catheter-directed thrombolysis, and percutaneous thrombectomy. This case highlights a relatively uncommon complication in children from long-term central venous catheter access and describes an emerging, minimally-invasive therapeutic alternative that allows ...

Torsion of a Myomatous, Non-gravid Uterus: CT Findings
Uterine torsion is a rare condition which is part of a spectrum of gynecological emergencies. If diagnosis is delayed or the condition is left untreated, severe consequences such as infertility and life-threatening complications can arise. As presenting features are often non-specific and can be similar to commonly encountered gastrointestinal and urinary conditions, computed tomography is usually the first imaging modality utilized in an emergency setting. It is therefore important that the radiologist is familiar with recognizing computed tomography features of uterine torsion. We share our findings in a patient with ute...

Clival chordoma with drop metastases
Chordoma is a rare midline malignant tumor arising from embryonic remnants of the primitive notochord. The base of the skull is the second most common site of disease after the sacrococcygeal region. Intracranial chordoma constitutes about 30-35% of chordoma cases. Metastasis from chordoma is uncommon but if occurs, it tends to spread to the lungs. Cerebrospinal fluid seeding or drop metastasis is very rare. Here we describe a case of a clival chordoma with drop metastases. (Source: Journal of Radiology Case Reports)

Neonatal neuroblastoma 4s with diffuse liver metastases (Pepper syndrome) without an adrenal/extraadrenal primary identified on imaging
We report the imaging appearances of a case of pathologically proven, neonatal neuroblastoma 4S with diffuse hepatic metastatic involvement at presentation. Patient had an abnormal appearing liver both by ultrasound and MR. There was no evidence for associated adrenal tumor by imaging. Lack of an associated adrenal mass led to initial misinterpretation of diffuse hepatic accumulation of MIBG seen with radionuclide scintigraphy. To the best our knowledge, this is the first report of metastatic neonatal 4S neuroblastoma without an adrenal (or extra-adrenal) primary identified either on pre- or post-natal imaging.

Extensive Thrombus and Brain Microabscesses After Sleeve Gastrectomy
We present a case of a 21-year-old woman who developed thrombosis of the portal, splenic, and right common iliac veins that then resulted in multifocal brain abscesses from presumed Fusobacterium septic emboli following an uncomplicated laparoscopic sleeve gastrectomy.

Optic Nerve Sheath Dural Arteriovenous Fistula Misdiagnosed As A Carotid Cavernous Fistula
We present an atypical case of a dAVf identified along the left optic nerve sheath. The patient presented with progressive ophthalmological signs and was initially misdiagnosed with a left carotid-cavernous fistula. The aetiology, classification and treatment options are discussed.

Temporal Evolution of Intramural Esophageal Dissection with 3D Reconstruction and Cinematic Virtual Fly-Through
We present a case of a 51-year-old male who first presented to the emergency department with fever, odynophagia, and dysphagia. He was treated for acute tonsillitis and discharged, but presented again after 10 days with worsening symptoms. A series of radiographs and computed tomography studies, with 3D reconstruction and cinematic virtual fly-through, in these 2 admissions depicts the temporal evolution of intramural hematoma to subsequent intramural esophageal dissection. Recognizing its appearance on imaging is invaluable in distinguishing it from other important differential diagnoses. A complete description of the cas...

Large septic pulmonary embolus complicating streptococcus mutans pulmonary valve endocarditis
We present a case of a 41 year-old woman who developed a large main pulmonary artery embolus and bilateral cavitary lung nodules in the setting of severe sepsis. Pulmonary artery exploration and clot retrieval ultimately revealed a large septic embolus from Streptococcus mutans native pulmonary valve endocarditis. The diagnosis of septic pulmonary emboli from right-sided endocarditis should be considered in patients with ancillary findings of septic embolic phenomenon, particularly the presence of multifocal cavitary nodules and in the setting of appropriate predisposing factors.

Brain Magnetic Resonance Imaging Findings in Poorly Controlled Homocystinuria
We present such a case which demonstrates not only extensive white matter abnormalities on magnetic resonance imaging, but also previously unreported basal ganglia signal abnormalities and imaging manifestations of increased intracranial pressure, likely caused by elevated methionine and betaine therapy. We also review the literature and discuss the potential underlying biologic mechanisms of these imaging findings. (Source: Journal of Radiology Case Reports)

Internal Hernia in Pregnant Woman after Roux-en-Y Gastric Bypass Surgery
We present a patient in the third trimester of pregnancy with an internal hernia following a laparoscopic Roux-en-Y gastric bypass for morbid obesity. We discuss the importance of computed tomography (CT) in the diagnosis of an internal hernia and review key CT findings including compression of the superior mesenteric vein, which proved to be crucial in diagnosing the internal hernia in this patient.
