We report the CT appearance of pancreatic metastases and describe their features in relation to the originating primary tumor. We also discuss some limitations in their differential diagnosis and report some theories explaining the pathogenesis of their occurrence. A total of 20 cases (9 males and 11 females) of pancreatic metastases were diagnosed at… (More)
This article reviews the CT imaging features of the most frequent mesenchymal tumors of the pancreas and stresses important distinctive patterns that may help distinguish specific entities. Various neoplasms (lymphangioma, lipoma, teratoma, pancreatoblastoma, schwannoma, neurofibroma, lymphoma, and sarcoma) are reviewed, with key differential points… (More)
OBJECTIVE The most frequent intracranial appearance in children with neurofibromatosis type 1 (NF1) is represented by the presence of hyperintense lesions on T2-weighted images, the so-called "unidentified bright objects" (UBOs). Di Paolo demonstrated that these lesions represent foci of myelin vacuolization with increased water content. The aim of this… (More)
BACKGROUND Glucocorticoids are the mainstay of treatment of idiopathic retroperitoneal fibrosis, but they often have substantial toxic effects. Several reports have suggested tamoxifen as an alternative to glucocorticoids. We compared the efficacy of prednisone with that of tamoxifen in maintainance of remission in patients with idiopathic retroperitoneal… (More)
In 1995, as a result of the observation of Rhabdoid elements among the other components of a Teratoid/Rhabdoid tumor (TRT), a new nomenclature was introduced, Atypical Teratoid/Rhabdoid Tumor (ATRT) of infancy and childhood. We report the clinical history and radiological findings in a child affected by central nervous system (CNS) ATRT.
Two cases of liposarcoma of the stomach are described. At computed tomography (CT) the neoplasms showed features of an aggressive malignant tumor, with no fatty values within. We discuss the differential diagnosis of such lesions and conclude that, although rare, liposarcoma should be considered as a possible diagnosis when a large exophytic gastric mass is… (More)
Peliosis hepatis is an uncommon benign disorder characterized by blood-filled cavities within the liver. We describe the sonographic, computed tomographic, and magnetic resonance appearance of a patient affected by peliosis hepatis with pseudotumoral and hemorrhagic evolution and direct demonstration of the ectatic vascular components.
Primary hepatic leiomyosarcomas are exceedingly rare tumors. To the best of our knowledge, only 17 cases have been reported in literature. We report the computed tomographic findings of two cases of primary location in the liver. We also discuss the differential diagnosis of such lesions.
PURPOSE The goal of this work was to describe MR findings (morphology, structure, signal intensity) of ovarian non-Hodgkin lymphoma (NHL). METHOD We reviewed the MR images of five female patients aged 13-70 years (mean 46 years) with histologically proven NHL of the ovaries. We evaluated morphological and signal intensity findings of the lesions. MR… (More)
