Diffuse Osteosclerosis with Hepatosplenomegaly
Source: AJR 2007; 188:S18-S20
A59-year-old man with left flank pain. Coronal T2-weighted MR image through spine reveals homogeneously decreased signal intensity of marrow. |
Intraventricular Mass
Source: AJR 2007; 189:S55-S57
A 71-year-old woman with syncope. Unenhanced axial CT scan of brain shows hyperdense, well-circumscribed 2-cm mass in atrium of right lateral ventricle. Note scant rim calcifications. Only mild adjacent vasogenic edema is seen, and there are no findings of hydrocephalus. |
Bilateral Pulmonary Sequestration with Bridging Isthmus in a Boy with Williams Syndrome
Source: AJR 2006; 187:W133-W134
A 5-year-old boy with Williams syndrome. Contrast-enhanced chest CT scan revealed well-defined heterogeneous mass at medial basal segments of bilateral lower lobes with midline bridging isthmus posterior to heart. |
High-Output Cardiac Failure in a Patient with a History of Hereditary Hemorrhagic Telangiectasia
AJR 2006; 187:S508-S510
A 62-year-old woman with history of hereditary hemorrhagic telangiectasia who presents with high-output cardiac failure. Anteroposterior chest radiograph reveals cardiomegaly and enlargement of central pulmonary vasculature, cephalization of pulmonary blood flow, and left pleural effusion. |
Solitary
Pulmonary Nodule with Enhancing Rim Sign
(AJR 2007; 188:S5-S6)
84-year-old man with recent cough. Unenhanced CT
scan through solitary pulmonary nodule shows homogeneous rounded
soft-tissue mass. |
Diffuse
Osteosclerosis with Hepatosplenomegaly (AJR 2007; 188:S18-S20)
A 59-year-old man with left flank pain. Subsequent contrast-enhanced
CT scan of abdomen verifies presence of increased bone density
secondary to organized trabecular thickening and deposition
along endosteal cortex. |
Cavitated Mass with Hypertrophic Osteoarthropathy
(AJR 2007; 188:S7-S9)
62-year-old man with several-month history of coughing and right lung mass. Chest CT scan shows large cavitated mass with thickened walls in posterolateral aspect of right upper lobe (arrow). |
