Paediatrics Flashcards
Lymphoma staging:
Lugano classification:
Stage I - One node/group of node.
Stage 1e - One extra-lymphatic site only (i.e. hepatic lymphoma, small bowel lymphoma WITHOUT nodal disease)
Stage II - two nodal groups on SAME side of diaphragm
Stage IIe - extralymphatic spread from a node
Stage III - nodes both sides of the diaphragm
Stage IV - nodal and separate extra nodal disease/ multiple extra nodal disease
A - absence of symptoms
B - presence of symptoms
Bulky - Single nodal mass >10cm, or 1/3 of thoracic diameter
What is VACTERL?
Conditions that are commonly seen together
V - Vertebreal anaomalies
A - Anal (imperforate anus 63%)
C - Cardiac
TE - Tracheoesophageal fistula
R - Renal
L - Limb (radial ray 58%)
Li Fraumeni syndrome - associated cancers
SCAB
Sarcomas - Osteosarcoma, Rhabdos
CNS tumours - glioma
Adrenal cortical tumours
Breast cancer
What are the diagnostic measurements for pyloric stenosis?
Pyloric length - >15mm
Transverse diameter - >12mm
Pyloric thickness - >3mm
What are the signs for congenial biliary atresia on USS?
Triangular cord sign - echogenic fibrous tissue adjacent to the portal vein
Absent gall bladder
What does double bubble sign suggest?
Duodenal dilatation.
Causes include: duodenal web, atresia, stenosis, annular pancreas
What is a leptomeningeal cyst?
Leptomeninges herniate through a skull fracture.
The fracture grows overtime as the CSF pulsates within the meninges
What is the most common cause of macrocephaly?
BESSI
Benign enlargement of the subarachnoid space in infancy
What is periventricular leukomalacia?
Ischaemia secondary to birthing.
Early - periventricular necrosis
Late - periventricular cyst formation
What is the grading for germinal matrix haemorrhage?
- Blood in caudo thalamic groove
- Blood in ventricles no dilatation.
- Blood in ventricles with dilation.
- Blood in brain parenchyma
What is pyriform aperture stenosis associated with?
Midline developmental problems.
Holoprocencephaly
Pituitary dysfunction
Central mega incisor.
Classic imaging appearances of a branchial cleft cyst?
Second arch cyst is most common
Cyst at level of angle of mandible
Lateral to the submandibular gland
Between the internal and external carotid arteries
How do you treat infantile haemangiomas?
Beta blockers
Classic imaging features of a cystic hygroma and what are its associations?
Lymphatic malformations
Cystic mass in the posterior triangle of the neck
Associated with Turners disease and Downs
Classic imaging features of Fibromatosis coli?
Torticollis
Enlarged sternocleidomastoid.
Average age for Croup and what infection causes it?
6mnths to 1 year
Parainfluenza virus
(Epiglottitis is 3-6 year, H. influenza)
Average age for epiglottitis and what infection causes it?
3-6 years old.
H. influenza.
(Croup is 6-12 months and parainfluenza virus).
Classic imaging appearance of meconium aspiration?
Asymmetric “ropy” lung densities.
Hyperinflation.
Pneumothorax
Classic imaging appearance of TTN?
Classic history of C-section, maternal diabetes.
Course interstitial markings
Fluid in the fissures
Findings peak at day one, and disappear by day 3.
Classic imaging appearance of RDS?
Pre term
Reduced lung volume
Bilateral diffuse ground glass (granular) opacities.

Group b Strep
What is pulmonary interstitial emphysema?
Ventilator pressure associated.
Cystic / linear radio lucencies with hyperinflation.
Sign of impending pneumothorax.
Classic imaging appearance of CPAM?
Multicystic lesion
Can communicate with the airway and can be filled with air
How can you differentiate between CPAM and sequestration?
Sequestration has a systemic feeding artery.
Sequestration typically left lower lobe.
What is the most common primary lung malignancy in children?
Pleuro pulmonary blastoma.
Correct positions for UVC and UAC?
UVC - atriocaval junction
UAC - initially travels inferiorly, then turns superiorly, with tip ending at T7
What is Swyer James syndrome?
Unilateral small hyperlucent lung due to air trapping, from post infective obliterative bronchiolitis.
Bronchiectasis of the affected lung.
What conditions are Kleinfelter disease associated with?
BCOG
Breast cancer
Choroid plexus cysts

How can you differentiate Ewing’s sarcoma from Pleuropulmonary blastoma?
Both present as massive thoracic masses.
Ewing’s destroys ribs.

A - isolated esophageal atresia
B - proximal fistula with distal atresia
C - distal fistula with proximal atresia
D - proximal and distal fistula
E - H type, isolated fistula
What are the different diagnosis for short microcolon vs long microcolon?
Short microcolon - colonic atresia
Long microcolon - meconium ileus (CF patients), ileal atresia
