Meningiomas comprise approximately 20% of adult primary intracranial neoplasms. Of these, benign meningiomas are known to have an indolent growth pattern, usually without infiltration into adjacent nervous tissue. Because meningiomas have a well-circumscribed character, surgery has historically been the preferred treatment when total resection can be achieved with reasonable morbidity. Surgical...

Erdheim-Chester disease (ECD) is a rare multisystemic non-Langerhans cell histiocytosis that may be clonal and inflammatory in origin. The hallmark of the disease is infiltration of various organ systems by CD68+/CD1a- histiocytes containing foamy lipid-laden inclusions. The manifestations and course of the disease are variable and depend on the organ systems that are affected. Patients may be ...

Tumor invasion of the vessels displays both therapeutic and prognostic implications and represents a challenge for head and neck surgeons. Although previous research has shown that ultrasound can detect such invasions, accurate sonographic parameters to do so have not yet been established. We sought to determine sonographic criteria which are able to characterize these invasions. A high-resolut...

A 2.5D digital picture is an array each cell of which is related to a list of color values; in other words, it can belong to several objects simultaneously. Classical notions of inside and outside being insufficient, we need to introduce nesting notions among objects: encasement and distance. We then define what a family of well-nested and significant objects is, to which it is possible to asso...

OBJECTIVES Review and correlate the computed tomography (CT) imaging features of pancreatic Non Functional Islet Cell Tumors (NFICT) and its hepatic metastases. METHODS CT examinations of 28 patients with pathologically proven diagnosis of pancreatic NFICT and no clinical symptoms or signs attributed to hormone overproduction, performed at Mallinkrodt Institute of Radiology, Saint Louis, Miss...

We present a case of a 59-year-old man with left upper alveolar numbness of 2 years' duration in the absence of sinonasal symptoms. On physical examination, he demonstrated mild left facial asymmetry and diminished sensation of his left upper alveolus from the left second upper incisor to first canine. CT imaging revealed chronic sinusitis changes of the left maxillary sinus, with reduced volum...

Encapsulating peritoneal sclerosis (EPS) is a poorly understood condition in which excess fibrosis results in an encasement of the small bowel, which can clinically result in obstruction. The condition is thought to be related to the persistent expression of transforming growth factor beta on mesothelial cells causing proliferation of subserosal fibroblasts, massive production of extracellular ...

A 46-year-old woman presented with a 6-month history of dyspnea and weight loss on a background of previous pneumonectomy for bronchial adenoid cystic carcinoma 14 years beforehand. Several years prior to this presentation, she had developed left vocal cord palsy and a metastatic lesion to the right buttock confirmed at resection. Investigations included CT pulmonary angiography and right heart...

The ordinary (OSC) and geosynthetic-encased stone column (ESC) with different bearing strata significantly influenced its behavior. paper established seven models for studying the behavior of floating columns using finite difference method (FDM). effect geogrid length on load-settlement behavior, bulging deformation, failure mode, load transfer coefficient were also analyzed based proposal mode...
