Inflammatory myofibroblastic tumor from molecular diagnostics to current treatment.

Inflammatory myofibroblastic tumor (IMT) is a rare neoplasm with intermediate malignancy characterized by a propensity for recurrence but a low metastatic rate. Diagnostic challenges arise from the diverse pathological presentation, variable symptomatology, and lack of different imaging features. However, IMT is identified by the fusion of the anaplastic lymphoma kinase (ALK) gene, which is present in approximately 70% of cases, with various fusion partners, including ran-binding protein 2 (RANBP2), which allows confirmation of the diagnosis.

An atypical radiographic appearance of a cardiac myxoma: case report and review of the literature.

Cardiac myxomas are the most common primary cardiac tumours in adults. They usually present as a solitary, solid mass in the left atrium. Their most common radiographic appearance is that of a hypodense lesion on computed tomography (CT) and inhomogeneous lesion (hypo to isointense on T1 sequences and hyperintense on T2 sequences) on magnetic resonance (MR) with some contrast enhancement.

Severe mitral stenosis secondary to eosinophilic granulomatosis resolving after pharmacological treatment.

We present a case of 44-year-old woman who underwent effective pharmacological treatment of severe mitral stenosis. The patient was hospitalized due to rapidly progressive dyspnea. Her medical history included asthma, perennial rhinitis, and nasal polyps.

Patient-prosthesis mismatch in patients treated with transcatheter aortic valve implantation - predictors, incidence and impact on clinical efficacy. A preliminary study.

Introduction: Patient-prosthesis mismatch (PPM) is relatively frequent after surgical aortic valve replacement (SAVR) and negatively impacts prognosis.

Aim: We sought to determine the frequency and clinical effects of PPM after transcatheter aortic valve implantation (TAVI).

Material And Methods: Overall, 238 patients who underwent TAVI were screened.

Assessment of the myocardial FDG-PET image quality with the use of maximal Standardized Uptake Value myocardial to background index. Application of the results in regard to semiquantitative assessment of myocardial viability with cardiac dedicated softwar.

Background: The objective of this study was to semiquantitatively assess the degree of myocardial fluorodeoxyglucose (FDG) uptake in glucose-loaded myocardial viability positron emission tomography/computed tomography (PET/CT) scans, to calculate the myocardial to background index, and correlate the index with image quality assessed on the basis of visual qualitative assessment.

Material And Methods: The myocardial FDG-PET/CT study was carried out in 69 non-diabetic patients, who had known coronary artery disease, by intravenous injection of 250 ± 70 MBq (range: 180-320 MBq) FDG. Images were interpreted visually and patients were divided into three groups according to the grade of myocardial uptake: optimal, suboptimal, and uninterpretable.
