Comparison of Diagnostic Performance in Mammography Assessment: Radiologist with Reference to Clinical Information Versus Standalone Artificial Intelligence Detection.

We compared diagnostic performances between radiologists with reference to clinical information and standalone artificial intelligence (AI) detection of breast cancer on digital mammography. This study included 392 women (average age: 57.3 ± 12.

Breast adenoid cystic carcinoma arising in microglandular adenosis: A case report and review of literature.

Background: Breast adenoid cystic carcinoma (AdCC) is a rare invasive carcinoma composed of epithelial and myoepithelial cells. Microglandular adenosis (MGA) is a rare benign proliferative lesion consisting of small, uniform, and round glands formed by a single layer of epithelial cells and basement membrane without a myoepithelial cell layer. MGA may progress to atypical MGA and carcinoma arising in MGA.

Primary pleural epithelioid angiosarcoma manifesting as a loculated hemothorax: A case report and literature review focusing on CT findings.

Primary pleural angiosarcoma (PPA) is an extremely rare and clinically aggressive tumor. We report the case of a 66-year-old man having PPA with chest computed tomography (CT) scan showing a large oval-shaped, nonenhancing high attenuation cystic mass in the left hemithorax. Morphological and immunohistochemical findings supported the diagnosis of epithelioid angiosarcoma.

The 8-Year Management of an Older Breast Cancer Patient by Non-surgical Primary Therapies and Minimized Surgery: A Case Report.

A 74-year-old woman presented with a palpable lesion in her right breast. At the time of her visit, she was taking medications for diabetes, hypertension, tremors, tinnitus, and lumbago. She was also caring for her husband, who had dementia.

Ultrasonographic Features and the Diagnostic Role of Core Needle Biopsy at Metastatic Breast Cancer in the Thyroid gland: A Case Report.

Metastases to the thyroid gland have rarely been reported in clinical settings, and the thyroid gland is an uncommon site for breast carcinoma metastasis. We report a case of a 64-year-old breast cancer patient diagnosed with metastatic breast carcinoma in the thyroid gland after performing ultrasonography (US)-guided core needle biopsy (CNB) and subsequent total thyroidectomy. On US, the thyroid lesion appeared to be mildly enlarged with multiple internal hypoechoic lines and a few microcalcifications without mass formation.

Malignant sweat gland tumor of breast arising in pre-existing benign tumor: A case report.

Background: Sweat glands belong to skin appendages. Sweat gland tumors are uncommon, especially when they occur as malignant tumors in the breast. We report a case of malignant sweat gland tumor of the breast, including imaging and pathological findings.

Cytokeratin7 expression in histologic and cytologic specimens of cystic neck metastasis from HPV positive squamous cell carcinoma of the tonsil: A case report.

The majority of cystic squamous cell carcinomas (SCCs) of the neck have been shown to be metastatic tumors from tonsillar SCCs associated with high-risk human papillomavirus (HR HPV). Recent studies have demonstrated cytokeratin (CK)7 involvement in the development of HPV positive SCC, but no report has been issued on its simultaneous expression in primary tonsillar and metastatic tumor with cystic change. We present a case of HPV positive tonsillar SCC of a 42-year-old male that initially manifested as a cystic neck mass expressing CK7, CK19, and p16 in primary and metastatic tumors.

A Pulmonary Sequestered Segment with an Aberrant Pulmonary Arterial Supply: A Case of Unique Anomaly.

We presented a rare case of a 64-year-old man with a combined anomaly of the bronchus and pulmonary artery that was detected incidentally. Computed tomography showed a hyperlucent, aerated sequestered segment of the right lower lung with an independent ectopic bronchus, which had no connection to the other airway. The affected segment was supplied by its own aberrant pulmonary artery branch from the right pulmonary trunk.

Clinical outcome of angiosome-oriented infrapopliteal percutaneous transluminal angioplasty for isolated infrapopliteal lesions in patients with critical limb ischemia.

Purpose: We aimed to evaluate the clinical usefulness and outcome of angiosome-oriented percutaneous transluminal angioplasty (IP-PTA) and its clinical outcome for isolated infrapopliteal lesions in diabetic critical limb ischemia.

Methods: We retrospectively reviewed 70 patients (82 limbs) with diabetic critical limb ischemia who had localized disease at the level of the infrapopliteal artery. Patients underwent IP-PTA between January 2011 and December 2013 and were followed up for a mean of 13 months.

Non-puerperal mastitis masking pre-existing breast malignancy: importance of follow-up imaging.

Mastitis is an inflammatory condition of the breast with common symptoms of pain, swelling, erythema, warmth, and fever. Diagnosis of mastitis is easily made on the basis of typical symptoms and ultrasonographic findings, such as diffusely increased echogenicity of the parenchyma and subcutaneous fat, or skin thickening. However, when it occurs in women middle-aged or older, associated malignancy should be considered.

Anomalous origin of the right pulmonary artery from the ascending aorta associated with patent ductus arteriosus: focusing on computed tomography findings.

Anomalous origin of one pulmonary artery from the ascending aorta (AOPA) is a rare congenital malformation. Fewer than 150 cases have been reported to date in the world, with 95 % of these documented during the first year of the patient's life. We encountered a rare case of AOPA associated with patent ductus arteriosus in a 41-year-old female, who had reached the most advanced age of any known, previously untreated AOPA patient.

Small-cell neuroendocrine carcinoma of the breast.

A small-cell carcinoma is one of the histologic subtypes of primary neuroendocrine carcinomas of the breast. A small-cell carcinoma is a rare entity of the breast and exhibits similar morphologic features as neuroendocrine tumors of the gastrointestinal tract and lung. We present the imaging and pathologic findings of a primary small-cell neuroendocrine carcinoma of the breast.

Treatment of an acute mycotic aneurysm of the common carotid artery with a covered stent-graft.

We report herein a case successful endovascular treatment with a stent-graft of a rare case of rapidly growing mycotic aneurysm of the left common carotid artery due to acute bacterial endocarditis after eradication of the infection. Infected mycotic aneurysms of the peripheral vasculature have been considered as a contraindication for stent-graft implantation because of the possibility of microorganism spreading to the stent-graft; however, if there is evidence of complete eradication of microorganism and surgery is not an option, stent-graft implantation can be an effective and safe treatment modality for exclusion of the mycotic aneurysm.

Non-invasive recognition of generalized coronary arteriosystemic fistulae by contrast echocardiography and multidetector CT.

Coronary artery fistulae, including generalized coronary arteriosystemic fistulae, are usually identified incidentally during invasive coronary angiographies. Generalized or multiple coronary arteriosystemic fistulae arise from all three major coronary arteries draining into the left ventricular chamber. In a patient with generalized coronary arteriosystemic fistulae, myocardial ischemia and diastolic volume overload of the left ventricle can be caused by a left-to-left shunt; however, the clinical and hemodynamic consequences are incompletely understood.

A case of iatrogenic aortic valve leaflet perforation after closure of a ventricular septal defect.

Aortic regurgitation caused by leaflet perforation is most frequently seen in association with infective endocarditis that involves the aortic valve. There have been occasional reports of iatrogenic aortic regurgitation caused by aortic valve injury after cardiac surgery with the use of the transaortic approach or invasive cardiac procedures. Suture-related aortic valve injury can develop during periaortic cardiac surgery, but this has been very rarely reported.

[A case of a Korean adult affected by type B Niemann-Pick disease: secondary sea-blue histiocytosis and molecular characterization].

Niemann-Pick disease (NPD) is an inherited metabolic disorder caused by a deficiency of the enzyme acid sphingomyelinase coded by SMPD1 gene. In contrast with type A NPD, a severe neurodegenerative disease of infancy, type B NPD patients have little or no neurodegeneration, and frequently survive into adulthood. Although over 100 mutations have been found within the SMPD1 gene causing NPD, there was only one report about SMPD1 mutation status of a Korean NPD patient.

Recurrence of atrial fibrillation correlates with the extent of post-procedural late gadolinium enhancement: a pilot study.

Objectives: We sought to evaluate radiofrequency (RF) ablation lesions in atrial fibrillation (AF) patients using cardiac magnetic resonance (CMR), and to correlate the ablation patterns with treatment success.

Background: RF ablation procedures for treatment of AF result in localized scar that is detected by late gadolinium enhancement (LGE) CMR. We hypothesized that the extent of scar in the left atrium and pulmonary veins (PV) would correlate with moderate-term procedural success.

Acute obstructive cholangitis after transarterial chemoembolization: the effect of percutaneous transhepatic removal of tumor fragment.

Acute obstructive cholangitis due to the migration of necrotized tumor fragment is a rare complication occurring after a transarterial chemoembolization. The percutaneous tumor removal procedure following percutaneous transhepatic biliary drainage is an appropriate treatment over endoscopic removal for the relief of acute cholangitis in this case. Following this serial management, no invasive hepatocellular carcinoma of the bile duct recurred after two years of follow-up.

N-terminal pro B-type natriuretic peptide and the evaluation of cardiac dysfunction and severity of disease in cirrhotic patients.

Purpose: Cardiac dysfunction and hyperdynamic systemic circulation may be present in patients with cirrhosis. The purpose of this study was to identify relations between plasma levels of N-terminal-proBNP (NT-proBNP), reflecting early ventricular dysfunction, and the severity of liver disease and cardiac dysfunction in cirrhotic patients.

Materials And Methods: Sixty-three cirrhotic patients and 15 controls (group 1) were enrolled in this study.

Familial isolated noncompaction of the ventricular myocardium in asymptomatic phase.

Isolated noncompaction of the ventricular myocardium (INVM) is a rare cardiomyopathy resulting from a failure of normal endomyocardial embryogenesis and it has been categorized as a form of unclassified cardiomyopathy. The disorder is characterized by an excessively prominent trabecular meshwork with deep intertrabecular recesses. Although the disorder is sporadic, familial incidence may occur.
