1. CT Radiographic Unknowns 66 yr old female with back pain

4. RADIOGRAPHIC FILM REPORT Radiographic Procedure: CT Scan Lumbar Spine Clinical Information: A 66 year old female with back pain Radiographic Findings: Lateral lumbar spine film shows loss of height at the T-12 vertebral body of 25% with end plate buckling. Axial CT scans at bone windows with reconstructed saggital images show compression deformity at T-12 with some anterior wedging. There is retropulsion of fragments into the spinal canal best seen on reconstructed views. This is causing moderate compromise of the canal of approximately 50%. Conclusion: Vertebral body fracture with 25% loss of height at T-12. This shows no obvious lytic component to suggest a metastatic lesion. There is some compromise of the central canal. Correlation with symptoms of cord or root compression is suggested.

8. RADIOGRAPHIC FILM REPORT Radiographic Procedure: CT Scan Thorax Clinical Information: A 60 year old male with abnormal CXR on screening physical Radiographic Findings: Frontal chest radiograph shows shallow inspiration. Dual lead pacemaker is in normal position. The cardiac silhouette is normal. There is increased soft tissue density extending into the superior mediastium distorting norml anatomy. Impression: Abnormal CXR. The possibility of adenopathy or mass would have to be considered. CT scan is suggested if no old films are available to indicate this as a static process. Axial CT scans of the chest show a single section at the level of the aortic arch. IV contrast is seen in the SVC and aortic arch. There is low density material seen extending at the margins of the arch anteriorly. This tissue is in a fat density range. Conclusion: Mediastinal fat at the level of arch accounts for findings on CT scan. This indicates a benign process, mediastinal lipomatosis. This can be seen in patients receiving steroid treatment.

50. Radiographic Film Report Radiographic Procedure: Abdomen – flat film Clinical Information:LUQ mass Radiographic findings: An AP, flat film of the abdomen showed splenomegaly. The vertical dimension of the spleen was approximately 17cm. The liver was at the upper limits of normal size. The bowel gas pattern was normal. The GI tube was looped in the stomach although the tip had advanced into the second portion (descending) of the duodenum. Conclusion: There is splenomegaly. Lumbar scoliosis was noted.
