Radiology Case Conference

  1. 1. Case Conference July 24, 2015
  2. 2. Pancreatitis
  3. 3. Imaging Indications • Acute interstitial edematous pancreatitis – Clinical diagnosis • Necrotizing pancreatitis
  4. 4. Pyelonephritis
  5. 5. Imaging Indications • Imaging often not necessary • May be appropriate in the following circumstances – Suspected obstruction – High risk (diabetes, immunocompromise) – Uncertain diagnoses – Previous renal abnormality
  6. 6. Positive UA
  7. 7. Positive UA
  8. 8. Emphysematous Cystitis • Rare – Diabetics, immunocompromised, neurogenic bladders • E. Coli, Enterobacter, Klebsiella, Proteus, S. Aureus, Clostridium perfringens, Candida albicans
  9. 9. Gastric Bypass
  10. 10. Intussusception
  11. 11. Fracture
  12. 12. Proximal Femur Fractures
  13. 13. Fracture
  14. 14. Segond Fracture • Avulsion fracture – Lateral tibial rim cortex, just distal to the plateau • Internal rotation, varus stress – Anterolateral rotatory instability • Lateral capsular ligament avulsion? – Alternatively, IT band, fibular collateral ligament • Strong association with ACL tear (~75%) and meniscal tears
  15. 15. Genu varum, Genu valgum
  16. 16. Fracture
  17. 17. Lange-Hansen
  18. 18. Suspected Pulmonary Embolism
  19. 19. Valsalva • SVC with bright contrast, IVC not well opacified, with mixing around the right atrium • Important to differentiate from imprecise contrast bolus timing as you can potentially repeat a PE CT if there is valsalva • Repeat the study on expiratory phase
  20. 20. Wells Criteria
  21. 21. D-Dimer • High negative predictive value • Poor positive predictive value
  22. 22. Abdominal Pain
  23. 23. Abdominal Pain
  24. 24. Sigmoid Volvulus
