Computed tomography (CT) is an excellent imaging modality for demonstrating the size, shape, and position of the spleen, as well as for depicting intrasplenic pathologic features. However, it has limited value in the diagnosis of splenic involvement by lymphoma. Greater accuracy in diagnosing splenic lymphoma may be obtained by demonstrating adenopathy in(More)
In this review, a brief discussion of the important events of pancreatic embryology is followed by presentation of congenital anomalies and normal variants. For each variant, the appearance at different radiologic modalities including computed tomography, magnetic resonance (MR) imaging, endoscopic retrograde cholangiopancreatography, MR(More)
Computed tomographic (CT) and angiographic findings in 14 patients (eight men, six women, aged 30-72 years) with sarcomatoid renal cell carcinoma (SRCC) and various types of renal sarcoma are described. There were four patients with SRCC; three, leiomyosarcoma; two, liposarcoma; two, fibrosarcoma; and one each of unclassified renal sarcoma, clear cell(More)
Twenty-three nonfunctioning adrenal nodules were discovered during computed tomographic (CT) evaluation of the abdomen in 16 patients with a variety of primary extra-adrenal malignant neoplasms. In seven cases the adrenal masses were bilateral. Following percutaneous fine-needle aspiration biopsy, pathologic diagnosis was consistent with benign adenoma in(More)
The computed tomographic (CT) findings in eight patients with splenic infarction are described and correlated with ultrasound (US) in three. The diagnosis was proven in four by splenectomy or autopsy, in three by comparison with CT, having been obtained shortly before infarction, and in two by angiography. In four patients the infarct occurred as a result(More)
Primary bone lymphoma is an uncommon malignancy that accounts for less than 5% of all primary bone tumors. The radiographic appearances of primary bone lymphoma are variable, and, because the lesion can appear near normal on plain radiographs, a second modality such as bone scintigraphy or magnetic resonance (MR) imaging should be used. Despite this(More)
This study evaluated the use of recombinant human bone morphogenetic protein (rhBMP-2) with various types of carrier media, and the effect of rhBMP-2 as an adjunct to autogenous iliac crest bone graft in the canine spinal fusion model. BMP induces mesenchymal cells to differentiate into cartilage and bone. The recent availability of rhBMP-2 has created the(More)
The response to intraarterial cis-diamminedichloroplatinum II (CDP) chemotherapy was evaluated by computed tomography (CT) in 33 patients with pathologically proved osteosarcoma of the long or flat bones. Twenty-one of the 33 patients had a CT scan before chemotherapy was started. In the other 12 patients, a CT scan was obtained after at least two courses(More)
