Brain axial T2W magnetic resonance imaging at the level of the lateral ventricles. Areas of high signal involving the periventricular white matter associated with enlargement of the lateral ventricles and widening of cerebral sulci.

Coronal, T2-weighted magnetic resonance imaging scan at the initial visit. No abnormal findings, except left hip joint effusion, were observed.

mri

Lateral view X-ray showing the soft neck tissue and revealing widening of the prevertebral space containing areas of mixed opacity and lucency extending from the base of the skull to the level of the seventh cervical spine (C7), with the laryngeal air column almost obliterated, anterior displacement of the airway and straightening of the cervical spine.

xray

Abdominal radiography showing the VPS catheter and a soft-tissue mass located in the upper abdomen.

xray

Cardiomegaly is substantial. Bilateral pleural effusions and bibasal consolidations are unchanged. Right mid lung consolidation is unchanged. Overall no substantial difference as compared to previous examination demonstrated but the might be potentially slight increase and vascular congestion in the left upper lobe.

xray

Erect abdomen radiograph shows large soft tissue density abdomino- pelvic mass (arrow) displacing bowel loops laterally and superiorly

ct

Low lung volumes. Heart size is normal. The mediastinal and hilar contours are normal. The pulmonary vasculature is normal. Lungs are clear. No pleural effusion or pneumothorax is seen. There are no acute osseous abnormalities.

xray

Metastatic bronchogenic carcinoma in the second metacarpal base. Radiograph of the left hand reveals a large, osteolytic, permeative, sightly expansile lesion in the base of the second metacarpal extending from the subchondral bone to the metacarpal shaft, with associated soft-tissue extension.

xray

Frontal portable chest radiograph demonstrates no intraperitoneal free air. The lungs are clear. There is no pleural effusion or pneumothorax. The heart size is normal, the mediastinal contours are normal. The pulmonary vasculature is normal in appearance.

xray

As compared to the previous radiograph, the patient has received a new Dobbhoff catheter. Tip is oriented superiorly, and is at the level of the gastroesophageal junction. There is no evidence of complications, notably no pneumothorax. The other monitoring and support devices, as well as the bilateral parenchymal opacities are unchanged.

xray

Overlying trauma board slightly limits assessment. The lung volumes are low. This accentuates the size of the cardiac silhouette which is mildly enlarged. There is no mediastinal widening. Crowding of the bronchovascular structures is likely related to low lung volumes. Mild atelectasis is noted within the lung bases. No focal consolidation, large pleural effusion or pneumothorax is identified. No displaced fractures are seen.

1. Cardiomegaly with central vascular congestion and increased interstitial opacities suggesting mild interstitial pulmonary edema. 2. Small bilateral pleural effusions. 3. No visible pneumothorax. AP and lateral view of the chest.

32-year-old man with history of Wilson's disease who presents with slurred speech. T2-weighed, axial MRI image shows presence of hyperintensities involving bilateral thalami. Minimal hyperintensities are seen involving bilateral lentiform nuclei.

Sagittal T1-weighted magnetic resonance (MR) image with gadolinium revealing an intramedullary lesion with peripheral enhancement at the C6/7 level

ET tube tip is 7.7 cm above the carinal. Left PICC line tip is in the right atrium and to secure it position at the cavoatrial junction or above should be pulled back 3 cm. No change in diffuse parenchymal opacities demonstrated, concerning for a inch though it potentially severe pulmonary edema.

T2 cardiac magnetic resonance imaging, coronal view, shows that the right atrial myxoma (arrow) obstructs the entrance of the inferior vena cava.

No acute preoperative findings. The cardiac contours are normal. The lungs are clear. Thoracic spondylosis.

xray

Magnetic resonance cholangiopancreatography showed wall thickening of the entire bile duct and segmental stenosis between 2 dilational parts (dashed line).

Comparison is made with prior study performed 3 hours earlier. Tiny left apical pneumothorax is less conspicuous than before. Elevation of the left hemidiaphragm is stable. Widened mediastinum has improved. Opacities in the left perihilar and left lower lung have improved, the right lung is grossly clear. Subcutaneous emphysema in the left chest wall is unchanged. Left apical chest tube remains in place.
