"Pure" large cell neuroendocrine carcinoma of the gallbladder. Report of a case and review of the literature

2016

Primary Neuroendocrine Tumours (NETs) of the gallbladder are rare. Among all NETs of the gallbladder, large cell neuroendocrine carcinoma (LCNEC) is exceedingly rare. In most of the cases LCNECs are combined with other histological components. We reviewed clinical presentation and management of all patients with "pure" LCNEC from published literature since the first case was published in 2000, as well as one patient from our experience. Only 7 cases of "pure" LCNEC has been described in the last 15 years, our case is the eighth. The diagnosis of gallbladder NETs is rarely made preoperatively since the presentation generally consists of non-specific symptoms including upper abdominal pain, d…

Technical development in cardiac CT: current standards and future improvements—a narrative review

2020

Non-invasive depiction of coronary arteries has been a great challenge for imaging specialists since the introduction of computed tomography (CT). Technological development together with improvements in spatial, temporal, and contrast resolution, progressively allowed implementation of the current clinical role of the CT assessment of coronary arteries. Several technological evolutions including hardware and software solutions of CT scanners have been developed to improve spatial and temporal resolution. The main challenges of cardiac computed tomography (CCT) are currently plaque characterization, functional assessment of stenosis and radiation dose reduction. In this review, we will discu…

Multimodalities imaging in diagnosis of pericardial cyst

2015

Pericardial cysts, an uncommon benign congenital anomaly belonging to the category of mediastinal masses. Cysts are usually detected incidentally on chest radiography or echocardiography, being most patients asymptomatic. In some cases, however, symptoms and complications occur, like dyspnea, chest pain, or persistent cough. Computed tomography and magnetic resonance imaging are the imaging techniques of choice to diagnose pericardial cysts. The removal of pericardial cysts is restricted to the cases with an uncertain diagnosis or in the presence of symptoms.

High-sensitivity Cardiac Troponin for the Evaluation of Patients With Suspected ACS: A True or a False Friend?

Routine cardiac troponin assessment after percutaneous coronary intervention

2019

: Although the angiographic and procedural success of percutaneous coronary intervention (PCI) is now very high, some severe complications may still develop, including periprocedural myocardial infarction (MI). An accurate diagnosis of this condition is essential for guiding the clinical management, as these patients may need a tailored management. The current recommendations for diagnosing periprocedural myocardial infarction based on the fourth universal definition appear at first sight straightforward, but the clinical and prognostic significance of routine periprocedural cardiac troponin (cTn) assessment remains uncertain. The current scientific evidence suggests that the likelihood of …

Computer-assisted interpretation of flow cytometry data in hematology.

1996

A computer program has been developed for computer-assisted diagnosis (including subclassification) of flow cytometry data of acute leukaemias and non-Hodgkin lymphomas by means of artificial intelligence. The knowledge base for the system has been formulatedas semantic networks that describe physiological hematopoiesisas well as the pathological situation (eg., aberrant antigen expression) of hematological disorders. The semantic networks reflect the hierarchy of cells and their occurrence in diseases, the normal and pathological antigen expression patterns of cells, cell maturation, and the frequency of cell populations in normal blood and bone marrow. Using these semantic networks, the d…

Role of prenatal magnetic resonance imaging in fetuses with isolated severe ventriculomegaly at neurosonography: A multicenter study.

2021

Objective: The aim of this study was to report the rate of additional anomalies detected exclusively at prenatal magnetic resonance imaging (MRI) in fetuses with isolated severe ventriculomegaly undergoing neurosonography. Method: Multicenter, retrospective, cohort study involving 20 referral fetal medicine centers in Italy, United Kingdom, Spain and Denmark. Inclusion criteria were fetuses affected by isolated severe ventriculomegaly (≥15 mm), defined as ventriculomegaly with normal karyotype and no other additional central nervous system (CNS) and extra-CNS anomalies on ultrasound. In all cases, a multiplanar assessment of fetal brain as suggested by ISUOG guidelines on fetal neurosonogra…

Moderne Diagnostik zystischer Leberläsionen und Hämangiome

2015

Clinical issue: Cystic liver lesions incorporate a broad heterogeneous group of mostly benign but also malignant abnormalities. The radiological aim is the non-invasive diagnosis with the use of different imaging modalities to determine the type of lesion.Standard radiological methods: The common generally asymptomatic incidental findings of cystic lesions on ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) must be classified on the basis of specific imaging features. Such a differentiation is essential because the clinical consequences and the appropriate therapy can vary depending on the underlying pathology. Due to the morphological overlap of many cystic lesions…

Lipoma of the fossa femoralis mimicking a femoral hernia. Report of 2 cases

2018

Highlights • Femoral lipoma can be mistaken with femoral hernia. • Differential diagnosis between femoral lipoma and femoral hernia can result challenging. • The occurrence of femoral pain can lead to misinterpretation of the symptoms.
