ACCIDENTAL HEAD TRAUMA Case Based

Page 5: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

3D MIP

Where is the fracture? 9-m, fell from couch onto floor

Page 6: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

Accidental trauma

• Children more likely to have skull fx

– Larger craniofacial ratio & thinner calvarium

– Child <2-y: 10% higher threshold for fx than older pt

• Axonal injury more common younger pt (<2yrs)

– Immature WM, cortical WM begins to myelinate around 4 months

– Shear injury and subtle edema can be obscured on CT

– Follow up MRI

Page 7: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

Imaging Pediatric Minor trauma

• 3-5% kids w/minor head trauma have abn imaging

– 4% incidental findings w/blunt head trauma (Rogers)

• <1% require neurosurgical intervention

• Role of skull radiographs is uncertain

– 21% of fractures detectable by CT may be missed

– CT can replace radiographs in many instances

• Emesis is not reliable indicator when no other sx

-J Am Coll Radiol 2014;11:939-947 ACR Appropriateness Criteria Head Trauma-Child -Rogers, etal. PEDIATRICS Volume 132, Number 2, August 2013 -Annals Emergency Medicine 2014;63:657-665

Page 8: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

When to Image? • Imaging not routine in minor trauma

– normal post event mental status. No neuro signs or sx.

• Imaging when clinical exam is indeterminate – Clinical eval can be difficult in children, preverbal.

• PECARN (pediatric emergency care applied research network) prediction rule – predicts need for imaging

– largest Prospective cohort study 42,412 <18yrs

– out performed CHALICE & CATCH on validation studies

– High sensitivity • 100% <2yrs & 98% >2yrs

Lancet 2009; 374: 1160–70 Arch Dis Child 2014;99:427–431

Page 9: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

CT • Excellent initial imaging test for suspected

intracranial trauma

• Hemorrhage, midline shift, herniation

• 3D recons allow detection of fx missed on XRAY

• Contrast may obscure punctate hemorrhages

• Mild edema may be subtle

• Fast quick imaging – New flash imaging avoids sedation

– Less motion artifact, avoids rescan

– decreases radiation dose

CT: WHAT ABOUT THE RADIATION?

Page 11: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

Radiation sickness or acute radiation syndrome is an immediate or acute reaction of the human body to radiation when the dose exceeds a specific

level or threshold

ALARA & IMAGE GENTLY Basic Principles

• Growing child 2-5x more sensitive to radiation

• longer latency period than adults

• ALARA= As Low As Reasonably Achievable

– Optimization of protocols, scan techniques, and pt prep to control exposure in children to ionizing radiation

• Dose reduction strategies in CT

– combination of technique and new technology

FACIAL BONE TRAUMA

Page 17: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

Facial Bone Fractures

• Interpretation pedi facial XR is challenging

– Particularly midfacial and condylar fractures

• CT is best modality

• Facial fx lowest infants and inc with age

• Usually associated severe trauma-MVA & sports

• Nasal bone fx most common followed by mandibular fx

RadioGraphics 2008; 28:441–461

• moderate/severe closed head injury

• Confusion most common initial symptom

• Temporal & Frontal lobes most common locations-bony protuberance, falx

• Evolve with time - Early CT maybe neg or edema

• Injury to superficial GM, WM is spared

– Multifocal punctate hemorrhages

• CT initially normal 50-80%

• 30% have negative CT but positive MRI

• Tragic-often brain stem spared- vegetative state

Page 40: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

NON ACCIDENTAL HEAD INJURY

“I really think its crazy that we hit our kids…Kids are the only people in the world that your aloud to hit. Do you realize that! They are the most vulnerable and the most destroyed by being hit, but it is totally okay to hit them…If you hit a dog they will … put you in jail...” --LOUIS CK

Page 44: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

“Non accidental” Head injury (NAHI)

• Leading cause morbidity & mortality abused child

• under 2yrs 80% of deaths from head injury

• Outcome is worse in NAHI than accidental

• High rate of mental disability

• brain can be injured w/out skull fx due to deformational changes of infant skull

Mechanism of Injury

Page 46: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

Head trauma-shaken baby syndrome

• Clinical presentation: seizures, apnea coma, cardiopulmonary arrest

• Main relate Injuries: subdural hemorrhages, retinal hemorrhages, bone fx & spine injury

• Cervical injury < 6mo old due to undeveloped cervical musculature

• Hypoxic-ischemic injury

– brain stem injury causing cardiopulmonary arrest and apnea resulting in brain swelling and DAI

Pediatr Radiol (2014) 44 (Suppl 4):S565-S570

Page 47: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

NAHI-what to order • Non-enhanced CT

– Initial work up

– 3D bone reconstructions • Excellent differentiate skull fractures from sutures

• MRI brain – neurologic symptoms

– other signs of abuse

– history of head trauma

– If abnormal CT add cervical spine

– Infarcts include MRA

• CT & MRI are complimentary

Page 48: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

Dating Hemorhages

• Evolution of attenuation changes can not give exact time frame as changes may vary pt to pt

• Serial imaging maybe needed

• MRI may be helpful in dating hemorrhages

Hypodense

< 3hrs

Hyperdense

Hrs to wks

Isodense

2-3 weeks

Hypodense

>3 wks

Page 49: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

Patterns of skull fracture in NAHI

• Soft tissue swelling maybe absent

• Multiple fractures

• Fractures that cross sutures

• Bilateral fractures

• Diastasis >3 mm, stellate, depressed & pingpong

• Bone scan & NaFl not as accurate for skull fractures-XRAY/CT is best

Page 50: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

PIT FALL CASE: 1 yr w/head swelling. Study read at adult hospital!

Typical appearance of metastatic neuroblastoma

Page 55: Pediatric Head Trauma Imaging Do’s & Don’ts...Pediatric Head Trauma Imaging Do’s & Don’ts Rachel Pevsner, D.O. Pediatric Radiologist Special thanks to Ricardo Restrepo, MD

Stay on target: Take Home Points • CT is a valuable tool!

• Head, Sinus or Facial Bones CT have radiation similar to 1 yr bkgd radiation

• Use NECT 1st for emergent eval

• 3D recons especially if <2yrs

• IF CT avail preferable to Facial XR

• MRI if neurologic or worsening sx.

• Skeletal Survey REQUIRED in suspected child abuse! DO NOT MISS NON ACCIDENTAL TRAUMA!
