Computerized Tomography Findings of a Sternal Osteosarcoma

Computerized Tomography Findings of a Sternal Osteosarcoma

Malignant bone tumors of the chest wall and sternum are more rare because most bone tumors occur in the long bones or joints.Osteosarcoma (OS) is a malignant bone tumor that occurs in the second or third decade of life. The men/women ratio is about 3:2 and half of the tumors occur near the knee. The most commonly occurring malignant tumor in sternum is chondrosarcoma and occurrence of osteosarc...

Computerized tomography findings in Fahr's syndrome.

We analyzed computerized tomography (CT) findings in six patients with Fahr's syndrome. They presented calcifications in basal ganglia, dentate nucleus, subcortical region and semioval center, due to alteration in calcium metabolism or due to senile relative hypoxemic state. The image pattern was not strictly related with etiology, although some differences in dystrophic senile calcifications (...

Fat poor renal angiomyolipoma: patient, computerized tomography and histological findings.

PURPOSE We reviewed our experience with fat poor cases of angiomyolipoma. MATERIALS AND METHODS The records of patients with angiomyolipoma, as determined by pathological study, from 1998 to 2004 were reviewed by recording patient demographics and outcomes. Fat poor cases were defined as the failure of imaging to demonstrate fat in a lesion. Computerized tomography and histological characteri...

Gastrointestinal Involvement in Langerhans Cell Histiocytosis: Computerized Tomography Findings

Computerized Tomography

Tomography refers to the synthesis of sectional images or slices from external measurements of a spatially varying function. Line integrals are the most common external measures, which are also known as projections. Availability of multiple projections at diierent orientations allows accurate recovery of the originating function. Because practical implementation of tomography typically requires...
