[Pediatric brain tumors of neuroepithelial tissue.]
Abstract Tumors of neuroepithelial tissue represent the largest group of pediatric brain tumors by far and has therefore been divided into several discrete tumor subtypes each corresponding to a specific component of the neuropil. The neuropil contains several subtypes of glial cells, including astrocytes, oligodendrocytes, ependymal cells and modified ependymal cells that form the choroid plexus. This review discusses the imaging aspects of the most common pediatric tumors of neuroepithelial tissue. PMID: 25085594 [PubMed - as supplied by publisher] (Source: Der Radiologe)

Pathological entities and their frequencies differ significantly from adult intracranial tumors and have age-specific differences in the pediatric population itself. In Germany treatment and diagnosis must be carried out according to ongoing multicenter trials for therapy optimization and registers of the Gesellschaft für pädiatrische Onkologie und Hämatologie (GPOH, Society of Pediatric Oncology and Hematology) in specialized centers for pediatric oncology.

[Tumors of the sellar and pineal regions.]
Abstract The (supra) sellar and pineal regions are relatively common sites for pediatric brain tumors; however, the distinct spectrum of space-occupying lesions is in marked contrast to that of the adult population. Craniopharyngeoma represents the most common intrasellar and/or suprasellar lesion in children, whereas the pituitary adenoma typical for adults- is generally rare. The pineal region is a predilection site for germ cell tumors in pediatric patients, while in adults this cancer category is largely confined to the gonads. The role of imaging is in the early detection of lesions, adequate demonstration of...

m F Abstract With an overall incidence of 10 % of all central nervous system tumors, spinal tumors are relatively rare in children. The majority of these tumors are astrocytomas and ependymomas (70 %) followed by rare non-glial tumor entities, such as gangliogliomas. They can be differentiated into intramedullary, extramedullary intradural and extramedullary extradural tumors according to their occurrence within the anatomical intraspinal compartments. The clinical presentation is generally unspecific. Longer lasting back pain or a gradually worsening scoliosis are often the first signs of the diseas...

Abstract The written radiological report is the most important means of communication between the radiologist and the referring medical doctor. There is no universal definition of a radiological report concerning its structure and content. The majority of clinicians and radiologists prefer structured reporting rather than free text reports of findings. Structured reporting does not increase the quality of a radiological report but has many advantages in research, teaching and quality management. Using standard RadLex terms facilitates translation and ontological assignment of a report. The Reporting Initiative of ...

Abstract Hepatocellular carcinoma (HCC) is the fifth most common cancer and the third most common cause of cancer death worldwide. The incidence continues to rise and only a detailed surveillance of patients with chronic liver disease can allow an early assessment. Diagnosis is made by imaging techniques, such as contrast-enhanced ultrasound (CEUS), computed tomography (CT), magnetic resonance imaging (MRI) and also histopathological examination of biopsy material. The determination of the tumor marker alpha fetoprotein (AFP) is no longer established for early detection but can be used as a supplement in addition ...

Abstract Hepatocellular carcinoma (HCC) is one of the most frequent malignancies worldwide. Besides liver transplantation, which is only feasible in few patients and surgical resection, the scope of potential treatment options has considerably expanded in recent years. Thermoablative therapies are now well established in early HCC due to the low rate of complications and short hospital stay. The disadvantage of higher relapse rates compared to surgical resection will be further diminished through technical advances regarding radiofrequency ablation and microwave ablation, as well as growing experience of users and...

Due to new developments in metal artifact reduction both methods can now be used for evaluation of a painful hip prosthesis. Iterative reconstruction algorithms and dual-energy scans are among the newer CT techniques for artifact reduction, while slice-encoding for metal artifact correction (SEMAC) and multi-acquisition variable-resonance image combination (MAVRIC) have introduced substantial improvements for MRI. Loosening of the hip prosthesis, osteolysis from sm...

Abstract Solitary plasmacytoma and multiple myeloma require a differentiated radiotherapy. The irradiation for plasmacytoma with an adequate total dose (medullary 40-50 Gy or extramedullary 50-60 Gy) leads to a high degree of local control with a low rate of side effects. In cases of multiple myeloma radiotherapy will achieve effective palliation, both in terms of recalcification as well as reduction of neurological symptoms and analgesia. In terms of analgesia the rule is the higher the single dose fraction the faster the reduction of pain. As part of a conditioning treatment prior to stem cell transpla...

Myeloma cells harbor a high median number of chromosomal aberrations and multiple changes in gene expression compared to normal bone marrow...

Abstract The finding of subsolid pulmonary nodules poses a frequent problem in the daily routine of the radiologist. The biological behavior of such subsolid lesions differs significantly from solid nodules. The risk of malignancy is significantly higher in subsolid nodules as compared to solid or purely ground glass opacities or nodules. The recommendations regarding the diagnostic management of subsolid nodules have been adapted according to the tendency of growth and the risk of malignancy. A benign etiology is also seen quite often in subsolid lesions and in this case they will show a reduction of size or disa...

CONCLUSION: The MRI technique has a sensitivity of approximately 80 % for detection of malignant pulmonary nodules compared to the reference standard low-dose computed tomography (CT) and is thus somewhat inferior to CT. Advantages of MRI on the other hand are a higher specificity in differentiating malignant and benign pulmonary nodules and the absence of ionizing radiation exposure. A systematic use of MRI as a primary tool for detection and characterization of pulmonary nodules is currently not recommended due to insufficient data. The diagnostic potential of MRI for early detection and staging of malignant pulmo...
