RATIONALE: Pulmonary hemangioma is a rare thoracic condition that can lead to hemoptysis. Here we report a case that presented with lumen dilatation suggestive of bronchiectasis on high-resolution computed tomography (CT) and was misdiagnosed as bronchiectasis for more than 10 years. PATIENT CONCERNS: A 41-year-old female patient was admitted to the Department of Respiratory Medicine due to hemoptysis. DIAGNOSES: The patient was misdiagnosed as having bronchiectasis for more than 10 years...

The low survival of patients with pancreatic ductal adenocarcinoma (PDAC) makes the treatment of this disease one of the most challenging task in modern medicine. Here, by mining a large-scale cancer genome atlas data set of pancreatic cancer tissues, we identified 21 long noncoding RNAs (lncRNAs) that significantly associated with overall survival in patients with PDAC (P < .01). Further analysis revealed that 8 lncRNAs turned out to be independently correlated with patients' overall survival, and the risk score could be calculated based on their expression...

Introduction: Thoracic endovascular aortic repair (TEVAR) has become the preferred option for treatment of thoracic aortic pathology, but lack of vascular access options is a common contraindication to TEVAR. Case report: The authors report a case of a 67 year old male patient with multiple revascularisation procedures: bilateral axillofemoral bypass and thoracic aortofemoral bypass, both occluded. An anastomotic pseudoaneurysm of the thoracic aorta developed and detected on computed tomography angiography (CTA)...

Background and Purpose: Traditional methods of computed tomographic angiography (CTA) can be unreliable in detecting carotid artery pseudo-occlusions or in accurately locating the site of carotid artery occlusion. With these methods, lack of adequate distal runoff due to pseudo-occlusion or intracranial occlusion can result in the inaccurate diagnoses of complete occlusion or cervical carotid occlusion, respectively. The site of carotid occlusion has important therapeutic and interventional considerations...

The medial prefrontal cortex (mPFC) has reciprocal projections with many cerebral structures that are crucial in the control of food ingestion behavior and reward processing; therefore, the mPFC has an important function in taste memory recognition. Previous results indicate that long-term consumption of sugar produces changes in appetitive re-learning and suggest that this could trigger an escalating consumption due to the inability to learn new negative consequences related to the same taste. Further evidence suggests that general identity reward value could be encoded in the mPFC...

Spinocerebellar ataxia type 8 (SCA8) is a rare autosomal dominant neurodegenerative disease caused by expanded CTA/CTG repeats in the ATXN8OS gene. Many patients had pure cerebellar ataxia, while some had parkinsonism, both without causal explanation. We analyzed the ATXN8OS gene in 150 Japanese patients with ataxia and 76 patients with Parkinson's disease or related disorders. We systematically reassessed 123 patients with SCA8, both our patients and those reported in other studies. Two patients with progressive supranuclear palsy (PSP) had mutations in the ATXN8OS gene...

BACKGROUND: Coronary computed tomographic angiography (CTA) is a reliable modality to detect coronary artery disease. However, CTA generally overestimates stenosis severity compared with invasive angiography, and angiographic stenosis does not necessarily imply hemodynamic relevance when fractional flow reserve (FFR) is used as reference. CTA-based FFR (CT-FFR), using computational fluid dynamics (CFD), improves the correlation with invasive FFR results but is computationally demanding...

BACKGROUND: Kawasaki disease is an acute febrile disease with mucocutaneous and cardiovascular involvement affecting infants and young children. Though coronary artery abnormalities are common in Kawasaki disease, no consensus has been reached regarding the treatment of acute coronary artery diseases in this population. CASE PRESENTATION: We described a case of myocardial infarction triggered by blunt chest wall trauma in a 20 years old girl. She presented with chest pain and breathlessness with brief syncope, lab results and electrocardiogram findings were consistent with acute myocardial infarction...

The fusion of 3D anatomical models derived from high-fidelity pre-interventional computed tomography angiography (CTA), and x-ray (XR) fluoroscopy to facilitate anatomical guidance is of huge interest for complex cardiac interventions like TAVI procedures with cerebral protection. Co-registration of CTA and XR has been introduced either based on additional intraoperative non-/contrast-enhanced cone-beam computed tomography (CBCT) or two separate aortograms. With the related increase of radiation exposure and/or contrast agent (CA) dose, a potential additional risk for the patient is introduced...

OBJECT: Intratumoral hemorrhage (ITH) associated with vestibular schwannomas (VS) is very rare. We retrospectively analyzed VS patients presenting with ITH in our department to further gain a better understanding of this uncommon clinical presentation. METHODS: We treated seven patients who had VS presenting with ITH between January 2012 and June 2017. All the patients had preoperative computed tomography (CT), computed tomography angiography (CTA), and magnetic resonance imaging(MRI) done which aided in the radiological diagnosis as well as postoperative MRI to confirm the resection extent of the VS...

Incorrect prosthesis size has direct impact on patient outcome after transcatheter aortic valve implantation (TAVI) procedure. Currently, annular diameter, area or perimeter may be used for prosthesis size selection. The aim was to evaluate whether the use different annular dimensions would result in the selection of different prosthesis sizes, when assessed in the same TAVI-candidate during the same phase of a cardiac cycle. Fifty consecutive TAVI-candidates underwent retrospectively ECG-gated computed tomography angiography (CTA)...

OBJECTIVES: Mechanical thrombectomy is the standard of care for stroke caused by an emergent large vessel occlusion in the anterior circulation, and the ability to rapidly review CTA is one hurdle in minimizing the time from diagnosis to intervention. We evaluated the diagnostic accuracy and confidence in review of stroke CTA for ELVO via a smartphone-based application as compared to PACS workstation. PATIENTS AND METHODS: Seventy-six head and neck CTA studies performed for stroke from one comprehensive and seven primary stroke centers were independently reviewed remotely on smartphone by two blinded interventional neuroradiologists in actual-use circumstances...

OBJECTIVES: This study sought to compare early emergency department (ED) use of coronary computed tomography angiography (CTA) and stress echocardiography (SE) head-to-head. BACKGROUND: Coronary CTA has been promoted as the early ED chest pain triage imaging method of choice, whereas SE is often overlooked in this setting and involves no ionizing radiation. METHODS: The authors randomized 400 consecutive low- to intermediate-risk ED acute chest pain patients without known coronary artery disease and a negative initial serum troponin level to immediate coronary CTA (n = 201) or SE (n = 199)...

A 61-year-old female patient with chronic hepatitis B virus infection was diagnosed with liposarcoma in a community hospital. Fine needle aspiration biopsy confirmed the diagnosis of well-differentiated liposarcoma. Abdominal computed tomographic angiography (CTA) showed that the mass adhered to and constricted the main trunk and branch of the superior mesenteric vein (SMV), especially the ileocolic vein, and collateral circulation was observed during the vascular reconstruction scan. The abdominal liposarcoma was resected...
