Peds Flashcards
Croup:
- age?
- cause?
6 months - 3 years
- parainfluenza
Epiglottitis
- age?
- cause?
- cause of death?
- 5 years old, also teens
- H. influenzae
- asphyxiation from aryepiglottic flods
exudative tracheitis:
- age?
- cause?
- 6-10 years
- staph A
most common soft tissue mass in trachea
subglottic hemangioma
PHACES syndrome
- Posterior fossa (DWM)
- Hemangiomas
- Arterial anomalies
- Coarctation of aorta/cardiac defects
- Eye abnormalities
- Subglottic hemangiomas
retropharyngeal soft tissues: normal thickness
6 mm at C2
22 mm at C6
Infantile vs. congenital hemangiomas
- infantile are not present at birth; show up around 6 months and nearly always involute
- congenital are present at birth and may or may not involute
neonatal pneumonia -GBS vs. non GBS
- low lung volumes for GBS
- other pneumonias have high lung volumes
- GBS pneumonia less likely to have pleural effusion than non-GBS
PIE
- timeline
- buzzword
- treatment
- warning sign for?
- what is a mimic?
- occurs in 1st week
- linear lucencies
- PIE side down position
- warning sign for impending pneumothorax
- mimic is surfactant replacement therapy
classic appearance for papillomatosis
multiple lung nodules with cavitation
- 2% risk for squamous cell cancer
pleuropulmonary blastoma
- typical location
- calcification?
- rib invasion?
- right sided and pleural based
- no calcification or rib invasion
- 10% have a multilocular cystic nephroma
- cystic type occurs in kids < 1 year old and tend to be more benign
most common mass in masticator space of kid
rhabdomyosarcoma
most common extra-ocular, intra-orbital malignancy in children
rhabdomyosarcoma
most common benign orbital mass in child
dermoid
differential for high lung volumes in neonate
- meconium aspiration
- non GBS neonatal pneumonia
differential for low to normal lung volumes in neonate
- surfactant deficiency
- GBS neonatal pneumonia
Transient tachypnea
- risk factors
- time course
- radiographic appearance
- maternal sedation, C-section, maternal DM
- starts at 6 hrs, peaks at 1 day, resolves by 3 days
- coarse intersitial markings with fluid in fissure
- normal to high lung volumes
risks of surfactant replacement therapy?
- was does it mimic
- pulmonary hemorrhage
- increased risk of PDA
- can cause bleb like lucencies - mimics PIE
Thymic rebound
- FDG avid
- drops out on opposed phase MRI
pulmonary slings
- associations
- tracheal stenosis
- compelte tracheal rings
- imperforate anus
- TE fistula
- horseshoe lung
- hypoplastic lung
Ladd’s procedure
- procedure done to prevent midgut volvulus
- Ladd’s bands are divided
- appendix is removed
- small bowel ends up on the right and large bowel ends up on teh eltq
Pyloric stenosis
- age range
- criteria
- clinical sign
- 2-12 weeks (peaks 3-6 weeks)
- 4 mm single wall; 14 mm length
- paradoxical aciduria
differential for long microcolon
- meconium ileus
- distal ileal atresia - contrast does not reach ileal loops
- total colonic aganglionosis can mimic microcolon
intussusception
- time frame
- size criteria
- classic lead points
- 3 months - 3 years
- > 2.5 cm
- Meckel’s, HSP vasculitis, enteric duplication cysts
