Gastroesophageal Variceal Filling and Drainage Pathways: An Angiographic Description of Afferent and Efferent Venous Anatomic Patterns
Ron C Gaba, Patrick M Couture, Janesh LakhooJournal of Clinical Imaging Science 2015 5(1):61-61 Varices commonly occur in liver cirrhosis patients and are classified as esophageal (EV), gastroesophageal (GEV), or isolated gastric (IGV) varices. These vessels may be supplied and drained by several different afferent and efferent pathways. A working knowledge of variceal anatomy is imperative for Interventional Radiologists performing transjugular intrahepatic portosystemic shunt and embolization/obliteration procedures. This pictorial essay characterizes the angiographic anatomy of varices in terms of type and frequency of ...

A Case Report of Delayed Diagnosed Chronic Aortocaval Fistula: A Rare Complication of Penetrating Trauma to the Abdomen
We report a case of traumatic ACP presenting with pulmonary hypertension and right heart failure symptoms 15 years after the initial penetrating injury. Although symptoms of pulmonary hypertension started 5 years ago, it was wrongly diagnosed and treated as chronic obstructive pulmonary disease. The presence of a continuous abdominal bruit and history of penetrating abdominal trauma gave rise to suspicion of a fistula, which was confirmed by computed tomography and angiography. Percutaneous closure of ACP was planned, but the patient died of severe pneumonia. The clinical presentation of chronic ACP can vary from being asy...

Percutaneous CT-Guided Ablation in the Hepatic Dome: Artificially Induced Pneumothorax for Safe Transpleural Access
We report a case of a radiofrequency ablation of a lesion in the hepatic dome, where an artificially induced pneumothorax was performed to guarantee a safe and effective access. The air was easily injected by a spinal needle and later aspirated by a single-lumen catheter. Induced pneumothorax shoud be considered in ablation of hepatic dome lesions, mainly when the transhepatic access is not appropriate. (Source: Journal of Clinical Imaging Science)

Giant Unruptured Sinus of Valsalva Aneurysm: An Unusual Cause of Right Heart Failure
We report a case of 17-year-old male with congestive right heart failure with a large, partially thrombosed unruptured aneurysm of the right sinus of Valsalva. The aneurysmal sac was compressing the right ventricular outflow tract causing marked dilatation of the right ventricle and atrium that was confirmed on contrast-enhanced computed tomography imaging. Unruptured sinus of Valsalva aneurysm causing right heart failure in adolescence has been rarely reported in literature. (Source: Journal of Clinical Imaging Science)

Percutaneous Coronary Intervention in Single Coronary Artery from Right Sinus: Radial Route is Right
We present percutaneous coronary intervention (PCI) using radial approach in a rare case of single coronary artery originating from the right sinus. Although these anomalies and stenosis of anomalous vessels have been described previously, treatment of atherosclerotic lesions by PCI has rarely been reported. There is a definite procedural risk during PCI in patients with a single ostium because dissection with the guiding catheter would result in a catastrophic event. Additionally, technical difficulties may occur due to the ostial configuration and course of the branch to be stented. The patient suffered an acute coronary...

Traumatic Extra & #8209;capsular and Intra & #8209;capsular Floating Fat: Fat-fluid Levels of the Knee Revisited
Derik L Davis, Prasann VachhaniJournal of Clinical Imaging Science 2015 5(1):60-60 Floating fat is a sign of acute bone injury at the knee following trauma. The goal of this article is to review the etiology, patterns, and mimickers of extra-capsular and intra-capsular floating fat, with the major emphasis on knee trauma in the acute setting. We will discuss the spectrum of multimodal imaging findings for rare presentations of extra-capsular floating fat, and contrast these with common and atypical forms of intra-capsular lipohemarthrosis, as an aid to the assessment of acute bone trauma at the knee.

Role of 123 I-Iobenguane Myocardial Scintigraphy in Predicting Short-term Left Ventricular Functional Recovery: An Interesting Image
Mauro Feola, Stephane Chauvie, Alberto Biggi, Marzia TestaJournal of Clinical Imaging Science 2015 5(1):56-56123 I-iobenguane myocardial scintigraphy (MIBG) has been shown to be a predictor of sudden cardiac mortality in patients with heart failure. One patient with recent anterior myocardial infarction (MI) treated with coronary angioplasty and having left ventricular ejection fraction (LVEF) of 30% underwent early MIBG myocardial scintigraphy/tetrofosmin single-photon emission computed tomography (SPECT) in order to help evaluate his eligibility for implantable cardioverter defibrillator (ICD). The late heart/medi...

Sinonasal Adenoid Cystic Carcinoma with Intracranial Invasion and Perineural Spread: A Case Report and Review of the Literature
We present the case of a 51-year-old patient with sinonasal adenoid cystic carcinoma (SACC). Computed tomography (CT) and magnetic resonance imaging (MRI) exams revealed an expansive process in the right nostril accompanied with perineural spread and invasion to the floor of the middle cranial fossa. Due to the size of the tumor and brain involvement, the Head and Neck Tumor Board (HNTB) recommended radiochemotherapy treatment to decrease the size of the lesion. Presently, the patient is undergoing treatment without major complications. (Source: Journal of Clinical Imaging Science)

Rare Malignant Tumors of the Breast
Trevor Miller, Constance Albarracin, Selin Carkaci, Gary J Whitman, Beatriz E AdradaJournal of Clinical Imaging Science 2015 5(1):58-58While the more common forms of breast cancer are well understood and recognized, there are many important rare malignancies that are less appreciated. Many of these cancers have imaging findings that, when understood, help to formulate a more educated differential diagnosis. In this article, the clinical features, imaging, and pathologic findings of rare breast malignancies will be discussed. (Source: Journal of Clinical Imaging Science)

Human Herpes Virus-8-Associated Multicentric Castleman's Disease in a Human Immunodeficiency Virus-Positive Patient with a Previous History of Kaposi's Sarcoma
We report a case of HHV-8-associated CD in an HIV-positive patient with a previous history of Kaposi's sarcoma (KS). The patient presented with progressive splenomegaly and diffuse lymphadenopathy, which can be seen in multicentric CD, KS, and HIV-associated lymphoma. There are no reliable clinical or imaging features to differentiate these diseases. Lymph node biopsy confirmed HHV-8-associated CD and excluded KS and lymphoma. Due to differences in treatment options and prognosis between the three etiologies, it is important for radiologists to include HHV-8-associated CD in the differential diagnosis when encounter...

Pineal Gland Lymphoma: Case Report and Literature Review
Akshya Gupta, Mahlon Johnson, Ali HussainJournal of Clinical Imaging Science 2015 5(1):51-51A 65-year-old male presented to our institution with acute-onset headache. Imaging studies demonstrated a mass in the region of the pineal gland, with subsequent histopathology findings being consistent with large B cell lymphoma. The patient was treated with methotrexate, but ultimately did not survive. Primary central nervous system (CNS) lymphoma rarely involves the pineal gland, but should be considered in the differential diagnosis of pineal gland tumors in the appropriate clinical setting.

Traumatic Brain Injury by a Closed Head Injury Device Induces Cerebral Blood Flow Changes and Microhemorrhages
Conclusions: These results suggest that changes in cerebral blood flow and hemorrhagic lesions can persist for sub-acute periods after the initial traumatic insult in an animal model. In addition, microhemorrhages otherwise not seen by susceptibility-weighted imaging are present in diverse regions of the brain. The combination of altered cerebral blood flow and microhemorrhages can potentially be a source of secondary injury changes following traumatic brain injury and may need to be taken into consideration in the long-term care of these cases.
