BACKGROUND Intravascular embolization of device fragments is a rare but potentially serious complication. METHOD A systematic search of the PubMed and MEDLINE databases for all articles pertaining to central catheter related embolization published in English between 1985 and 2007 was made. RESULTS A total of 215 cases of intravenous catheter(More)
RATIONALE AND OBJECTIVES Most secondary intramammary tumors occur as metastatic involvement from the contralateral breast. Breast metastases (BM) from nonmammary malignancies are very rare. The aims of this study were to estimate retrospectively the prevalence of BM from nonmammary malignancies and to describe their radiologic appearance. MATERIALS AND(More)
PURPOSE Primary extranodal lymphomas of the orbit and sinonasal region are rare and occur almost only as Non-Hodgkin lymphoma (NHL). The purpose of this study was to determine the frequency of different subtypes of NHL in these regions and to describe their radiological features. MATERIALS AND METHODS Between January 2005 and January 2010, 567 patients(More)
OBJECTIVES To analyze possible associations between functional simultaneous (18)F-FDG-PET/MR imaging parameters and histopathological parameters in head and neck squamous cell carcinoma (HNSCC). MATERIAL AND METHODS 11 patients (2 female, 9 male; mean age 56.0years) with biopsy-proven primary HNSCC underwent simultaneous (18)F-FDG-PET/MRI with a dedicated(More)
Nonthrombotic pulmonary embolism is defined as embolization to the pulmonary circulation caused by a wide range of substances of endogenous and exogenous biological and nonbiological origin and foreign bodies. It is an underestimated cause of acute and chronic embolism. Symptoms cover the entire spectrum from asymptomatic patients to sudden death. In(More)
PURPOSE To describe the mammographical and ultrasound features of IM, and to compare radiological patterns of IM arising from different malignancies. MATERIALS AND METHODS A retrospective search in the statistical database of our institution from January 2000 to December 2009 revealed 51 cases of intramammary metastases from solid malignancies.(More)
PURPOSE Incidental findings are a common feature in computer tomographic examinations of the chest. Breast incidentalomas, however, were described only sporadically. The purpose of this study was to evaluate retrospectively incidental breast findings and to compare radiological features of benign and malignant breast lesions. MATERIALS AND METHODS From(More)
BACKGROUND Primary breast sarcoma is very rare. Most reports regarding sarcoma of the breast are clinical observations or pathological series and provide either no or inconstant radiological information. Radiological publications consist predominantly of isolated case reports or small series. PURPOSE To determine the prevalence, clinical signs, and(More)
BACKGROUND Thyroid carcinomas represent the most frequent endocrine malignancies. Recent studies were able to distinguish malignant from benign nodules of the thyroid gland with diffusion-weighted imaging (DWI). Although this differentiation is undoubtedly helpful, presurgical discrimination between well-differentiated and undifferentiated carcinomas would(More)
Muscle lymphoma (ML) is a very rare disorder. Its frequency varies and is reported to be 0.1-1.4% of all extranodal lymphomas. ML can develop either as primary extranodal intramuscular lymphoma or as intramuscular manifestation of disseminated disease. There are only few reports describing radiological features of ML. Therefore, the aim of this review was(More)
