What heart condition does this kid have? (spelling counts)
Tetralogy of Fallot
-congenital heart disease
-VSD
-RVOT obstruction
-Overriding Aorta
-RV hypertrophy
-On xray = classic boot shaped heart
200
What is the underlying pathology?
ACL Tear
Signs of ACL Tear on Xray:
Segond Fracture
Lateral Femoral Notch Sign (aka deep sulcus sign)
200
Most important diagnosis?
Non-accidental Trauma
200
2 year old. Diagnosis?
Retinoblastoma
Average age 2 years old
Contrast-enhancing retinal mass usually with some calcification
Can be bilateral
200
What is the IR attending's extension?
85302
300
What is this?
Aspergilloma
-Usually asymptomatic (may have hemoptysis)
-Ball of fungus within a cavity
-Monod Sign - Round mass surrounded by crescent of air
-Can be shown as mobile
300
What is the pathology causing this appearance? (not the name of the sign)
Bucket Handle Tear of the Medial Meniscus
torn section flips medially and ends up anterior to the PCL creating the "double PCL sign"
300

400
Patient with gun shot to chest. What would you call the finding indicated by the arrow?
Pulmonary laceration
-The lung parenchyma has elastic recoil. When there is a laceration, the lung parenchyma retracts creating a cavity (sometimes with an air fluid level).
-laceration is surrounded by hemorrhage (contusion) with an associated small hemothorax.
400
What is the name of the entity where the ulnar collateral ligament of the thumb is torn and displaced superficially to the adductor pollicis aponeurosis giving a "yo-yo on a string" appearance?

abnormal chest finding on prenatal ultrasound. Diagnosis? (will accept abbreviation)
CPAM (Congenital pulmonary airway malformation)
-Multicystic masses in a lung segment with abnormal bronchial proliferation
- Unilateral, single lobe
-Type I is most common (large cysts)
400
Patient had cardiac arrest 3 days ago. What is this?
Cortical Laminar Necrosis
-Occurs when the brain is derived of nutrients (hypoxia, ischemic event, hypoglycemia, increased demand such as status epilepticus)
-Gyriform hyperattenuation on non-con CT and T1 hyperintensity on MRI. In very early stages can restrict diffusion. Can calcify in chronic stages
-Signal characteristics are from denatured proteins in dying cells in the vulnerable cortical layers, not hemorrhage.

Premature baby. Very sick. Diagnosis?
Necrotizing Enterocolitis
-higher cases in premature babies
-usually first 2-3 days of life
-idiopathic, but suggested that the intestinal flora migrates into the immature mucosa of the intestines causing inflammation, hemorrhage, and necrosis
-On xray, will see dilated featureless loops of bowel, bowel wall edema with thumbprinting, pneumatosis instestinalis, and portal venous gas
500
Intractable epilepsy. Diagnosis?
(Subependymal) Grey Matter Heterotopia
-interruption of the normal neuronal migration
-nodules of grey matter just under the ependyma of the ventricles
- usually mild cognitive deficits that progresses into seizures later in life
- nodules follow grey matter on all sequences and do not enhance
