Radiology Pictures Final Flashcards
Pathology
Tarlov or Arachnoid Cyst
Pathology
Empty Sella
-Normal sella = 16x12 mm
Pathology
Basiliar Invagination from Arnold-Chiari malformation
-Notice the disruption of Chamberlain and/or McGregors lines along with a Syrinx (syringomyelia) posterior to C2
Pathology
Pituitary Macroadenoma
-One potential cause of Empty Sella seen on X-ray
Pathology
Neurofibroma
-Benign nerve sheath tumors
Pathology
Multiple Sclerosis
Pathology
Subdural Hematoma
- Concave = Subdural = Vein
- Convex = Epidural = Artery
Pathology
Epidural Hematoma
Pathology
Hydatid disease
Pathology
Abdominal Aortic Aneurysm
- Normal = < 3 cm
- >5 cm is serious (possible surgical intervention)
Pathology
-Patient is an alcoholic
Pancreatic lithiasis
-look for midline densities around L1, L2, and L3 (lateral shows them as anterior to the lumbar spine)
Pathology
Hiatal Hernia
-Sliding is the MC
Pathology
Bowel Blockage
- if 3 or more fluid levels in air pockets = blockage
- or see a Zig-Zag appearance
Radiographic sign
-What is the Dx?
Napkin Ring / Apple Core
-Colorectal Cancer
Pathology
- No blood in stool
- No clinical s/s
Colon Polyp
-No blood or clinical s/s make colon cancer less likely since they both look similar on CT (virtual colonoscopy)
Pathology
-Lateral shows calcification anteiror to the vertebral bodies
Cholelithiasis
-If calcification is on or posterior to vertebral bodies = Kidney stones
Radiographic Sign
-What does it indicate?
Milk of Calcium bile
-from chronic obstruction of the gall bladder probably from gallstones
Radiographic sign
-Is any follow up required?
Porcelain gallbladder
-YES! can turn into adenocarcinoma
What caused this patient to have Atelectasis?
Pleural Mesothelioma
-Extrapleural sign is evident on the lateral part of the lung field (increased density represents the tumor)
Pathology
-What differential is used for tumors in this location?
Teratoma of the Anterior Mediastinum
-3 T’s and an H ( Thymoma, Teratoma, Thyroid goiter, Hodgkin’s)
Pathology
Acute Respiratory Distress Syndrome
-No clear heart shadow because of fluid in the air space
+Silhouette sign bilateral
Pathology
-Stone cutter for 30 years
Silicosis (type of Pneymoconiosis)
-Reticulonodular pattern (looks like a interstitial disease)
Pathology
Pneumothorax
Radiographic Sign
-What is the Pathology?
Angle Wing Appearance (Giant Tubers)
Dx: Sarcoidosis
Pathology
Bladder Calculi
Pathology
Phleboliths
-DO NOT CONFUSE with bladder calculi
Pathology
-Lateral appears to show calcifications inside the vertebral bodies and posterior to the spine.
Nephrolithiasis
Pathology
Uterine Fibroma
-looks like bladder stone or phleboliths, but the fact it is in the superior part of the pelvis makes fibroids more likely.
