Radiology Live Unit 5 Flashcards
Usual location for morgagni
Right sided, causes right paracardiac opacity
Chance of recurrence after successful air reduction of ileocolic intussusception
10-15%
Most specific US feature of wilms
Tumour pseudocapsule
Neuroblastome vs wilms calcification
Fine, stippled vs coarse chunky
Trummerfield zone
Lucent metaphyseal band with adjacent sclerosis, suggests scurvy
Most likely cause of right paracardiac opacity on neonatal CXR
Morgagni hernia
CCAM associated with renal agenesis
Type 2
Thanatophoric dysplasia skull
Macrocephaly with large anterior fontanelle
Prenatal CCAM associated with
Hydronephrosis
Hepatoblastoma vs infantile haemangioma calcifications
Hepatoblastoma are coarse and chunky, Haemangioma are fine and stippled
Painful swelling of hands and feet in sickle cell
Dactylitis, or hand-foot syndrome
Smooth, single layered periosteal reaction in diaphysis of long bones (infant)
Physiological periostitis
2 week old, heterogenous suprarenal mass with no calcifications
Adrenal haemorrhage
Hurlers spine features
anterior inferior beaking
Mesoblastic nephroma vs wilms
Mesoblastic nephroma is homogenous & more well defined
Hurlers underlying pathology
Accumulation of Dermatan and Heparan Sulfate
Best sequence to look for fat to differentiate Wilms from AML
T1 fat sat
Heterogenous suprarenal mass in neonate US
Likely adrenal haemorrhage, f/u rpt US in 1-2 weeks
Metaphyseal fraying and cupping
Vit D deficiency (Rickets)
Isolated vertebra plana
LCH, usually spontaneously resolves
Optic glioma Rx
Observation with MRI, usually WHO grade 1
CCAM and renal cysts on prenatal US, Ix
Foetal MRI
Diffusion restriction in posterior fossa
Medulloblastoma
Frankel’s line
Dense white line at the metaphyseal end of growth plate, specific to scurvy
Neonate with congenital diaphragmatic hernia Iz
US chest and abdo
Most sensitive to detect calcifications in paeds liver masses
CT
