Invasive fungal diseases (IFD) are a primary cause of morbidity and mortality in patients with haematological malignancies. These infections are mostly life-threatening and an early diagnosis and initiation of appropriate antifungal therapy are essential for the clinical outcome. Most commonly, Aspergillus and Candida species are involved. However, other Non-Aspergillus moulds are increasingly identified in case of documented IFD. For definite diagnosis of IFD, a combination of diagnostic tools have to be applied, including conventional mycological culture and non-conventional microbiological tests such as antibody / antigen and molecular tests, as well as histopathology and radiology...

BACKGROUND: We make surgical strategies for ground glass opacity (GGO) nodules currently based on thin-section(TS)-CT findings. Whether radiologic measurements could precisely predict tumor invasion and prognosis of GGO-featured lung adenocarcinoma is uncertain. METHODS: We retrospectively evaluated medical records of patients with radiologic GGO nodules receiving surgery at FUSCC. The study endpoints were the predictive value and prognostic significance of radiologic measurements (CTR value, consolidation size and tumor size) for pathologic lung adenocarcinoma...

Acute pancreatitis is a potentially life-threatening disease, which is morphologically classified into interstitial edematous or necrotizing pancreatitis. According to the revised Atlanta classification, mild, moderate and severe clinical courses are differentiated regarding local and systemic complications as well as concomitant organ failure. In the initial disease phase, the therapeutic measures are focused on (aggressive) volume replacement, early enteral nutrition and adequate analgesia. Characteristic in the course of severe acute pancreatitis are abdominal necroses, which require individualized and interdisciplinary treatment with antibiotic therapy, drainage and definitive necrosectomy...

Background: Primary hyperparathyroidism (PHPT) is a common endocrine disease with a variable clinical presentation. PHPT is usually symptomatic at presentation in majority of the patients, especially in developing countries. As the accessibility to investigations, advanced imaging methods and surgical procedures are improving, the clinical profile of the patients with PHPT has undergone a palpable change compared to the earlier description. Hence we decided to look for a change in clinical, imaging and surgical outcomes of PHPT patients from South India...

Objectives: The eighth edition of the American Joint Committee on Cancer staging manual now stratifies nonmucinous lung adenocarcinomas (nmLACAs) by the size of the invasive component only. This is determined by direct gross or microscopic measurement; however, a calculated invasive size based on the percentage of invasive growth patterns has been proposed as an alternative option. Methods: To compare radiologic with different pathologic assessments of invasive tumor size, we retrospectively reviewed a cohort of resected nmLACAs with a part-solid appearance on computed tomography (CT) scan (n = 112)...

Pulmonary embolism (PE) is associated with approximately 100,000 deaths per year in the United States and the incidence of deep vein thrombosis/pulmonary embolism in the US is estimated at more than 350,000 cases annually (1). The diagnosis of pulmonary embolism poses a diagnostic challenge in the Emergency Department (ED), despite, validated decision rules, lab tests, and radiographic imaging (2, 3). While a simple lab test would be ideal for diagnosis, the well-known D-dimer test is, at its best, only about 54% specific (4)...

There has always been a need for a more accurate diagnosis than the history and clinical examination allow. This was the very foundation for the evolution of the field of radiology and arthroscopic surgery. Before 1972, the imaging option (arthrography) was invasive and of limited use; therefore, arthroscopic surgery, as a much more accurate diagnostic tool, became widely accepted over time, even though it was more invasive. We should remember that this was not without a high degree of controversy and scorn...

Although male breast cancer represents only 0.5%-1% of all breast cancer cases in the United States, the incidence of this disease is slowly rising [1]. Because of its extremely low prevalence, screening and treatment guidelines are not well established. Thus, analyzing cases of male breast cancer can accelerate this process. We present a case of a 52-year-old man, initially diagnosed with biopsy-confirmed intraductal papilloma without atypia, who presented 3 years later with progression of this benign lesion to ductal carcinoma in situ and development of de novo invasive ductal carcinoma...

The administration of target inhibitors is paramount to grant the longest survival in patients with ALK-positive non-small cell lung cancer (NSCLC). The eventual resistance to tyrosine kinase inhibitors (TKI) is monitored clinically and radiologically for prompt molecule shift to further generation TKI, if available. However, the early radiological detection of progression pattern (e.g. nodule onset) should be regarded with caution because overlaps exist with non-tumor cell proliferation and/or accumulation...

Non-invasive prediction of isocitrate dehydrogenase ( IDH ) genotype plays an important role in tumor glioma diagnosis and prognosis. Recently, research has shown that radiology images can be a potential tool for genotype prediction, and fusion of multi-modality data by deep learning methods can further provide complementary information to enhance prediction accuracy. However, it still does not have an effective deep learning architecture to predict IDH genotype with three-dimensional (3D) multimodal medical images...

Pulmonary vasculitides are caused by a heterogeneous group of diseases with different clinical features and etiologies. Radiologic manifestations depend on the predominant type of vessel involved, which are grouped into large, medium, or small-sized vessels. Diagnosing pulmonary vasculitides is a challenging task, and radiologists play an important role in their management by providing supportive evidence for diagnosis and opportunities for minimally invasive therapy. This paper aims to present a practical approach for understanding the vasculitides that can affect the pulmonary vessels and lungs...

Drug-eluting bead transarterial chemoembolization (DEB-TACE) is a well-established, minimally invasive interventional treatment for nonresectable hepatocellular carcinoma (HCC). Generally, TACE is regarded as safe and effective with a low complication rate. However, remote gastrointestinal ischemia due to the carryover of embolic material into visceral arteries is a rare but serious complication of TACE. In this report, we present a case of duodenal ulceration with contained perforation and severe necrotizing pancreatitis after TACE in a patient with nonresectable HCC and underlying hepatitis C virus associated with Child-Pugh stage B liver cirrhosis...

Anastomotic colorectal strictures are rare but potentially troublesome complications requiring additional corrective procedures1. Balloon dilatation using single or combined endoscopic or/and radiological approach represents the most common treatment but requires ability to intubate the stricture. Surgical reconstruction if balloon dilatation is unsuccessful is very challenging. Transanal minimally invasive surgery (TAMIS) alone or combined with laparoscopic transabdominal approach appears promising in a variety of situations including management of anastomotic complications2...
