Drs. Olson’s and Jackson’s CMC Pediatric X-Ray Mastery: October Cases
1. Pediatric Chest X-Rays of the Month

Chest X-Ray Mastery Project
October 2020
2. Process and Disclosures
This ongoing pediatric chest x-ray
interpretation series is proudly sponsored
by the Emergency Medicine Residency
Program and Pediatric Emergency Medicine
Fellowship at Carolinas Medical Center.
The goal is to promote widespread mastery
of CXR interpretation.
Cases are submitted by contributors from
many CMC departments, and now…
Tanzania and Brazil.
Ages have been changed to protect patient
confidentiality. No protected health
information (PHI) will be shared.

What’s the xray
finding?
What’s the diagnosis?
HPI:
2-year-old presents
after playing with a
kitchen timer. Mom
can’t find the battery
8. v
Xray finding: A foreign
body with a “halo rim”
Diagnosis: Button
Battery Ingestion
HPI:
2-year-old presents
after playing with a
kitchen timer. Mom
can’t find the battery
9. Think about button battery ingestion when…
• Acute onset cough or gagging
• Acute onset drooling & dysphagia
• Acute onset vomiting
• First time wheezing
• Refusing to eat or speak
• Stridor with no other URI symptoms
• Acute GI bleed
Especially in teenagers with SI, children with
developmental delay, infant who crawl

Where is the battery?
In the ED, the patient
is playful and in no
respiratory distress
12. Button Battery Tips
• Remember your ABCs
• Give honey if ≥1years old and
no airway compromise,
otherwise NPO
• Immediately obtain an XR of
the neck, chest, and abdomen
• Look in the nose, mouth, and
ears
• Follow the guidelines
• Follow up is key!

13. Time is mucosa!
Visible tissue injury caused by the CR2032, alkaline, silver oxide, and zinc–air button batteries after 6 hours in
thawed sections of cadaveric piglet esophagus
The Laryngoscope, Volume: 127, Issue: 6, Pages: 1276-1282, First published: 09 November 2016, DOI: (10.1002/lary.26362)
Half of the mortalities related to button battery ingestion were associated with
misdiagnosis!
14. Honey is the gold standard!
The mucosal surface of cadaveric porcine esophageal tissue exposed to the anode side of a 3V‐CR2032 button
battery underwent serial 10‐mL irrigations at 10‐ to 15‐minute intervals with a solution of interest starting at t = 10
minutes. Shown are representative images of the esophageal mucosa att = 2 hours
The Laryngoscope, Volume: 129, Issue: 1, Pages: 49-57, First published: 11 June 2018, DOI: (10.1002/lary.27312)
Honey was proven to slow the discharge of the button batter
and neutralize the tissue’s pH
17. HPI
15 –year-old with history
of autism and
constipation presents
with belly pain and no
stool for 6 weeks
Spot the abnormality
18. HPI
15 –year-old with history
of developmental delay
presents with belly pain
and no stool for 6 weeks
Fecal impaction
19. Hospital day 1-2:
An NG was placed and he
given 4 liters of Golytley
without stool and has
worsening of his
abdominal distension. He
was start of enemas with
no success.
Spot the abnormality
20. Hospital day 1-2:
An NG was placed and he
given 4 liters of Golytley
without stool and has
worsening of his
abdominal distension. He
was start of enemas with
no success.
Worsening distention
with giant stool ball
21. Hospital day 3:
Transferred to the
children’s hospital where
he was manually
disimpacted under
anesthesia that took 2.5
hours
What is your
impression of the post-
disimpaction film?
22. Hospital day 5:
He had a rectal biopsy
with absent ganglia.
Persistent large
amounts of stool on XR
Diagnosis?
23. Returned one month later
for sigmoid colectomy
and colostomy
Hirschprungs!
24. HPI
Unvaccinated 1.5 year old
with a history of
Hirschsprungs presents
with bilious vomiting,
refusing solids, and
diarrhea.
Spot the abnormality
25. HPI
Unvaccinated 1.5 year old
with a history of
Hirschsprungs presents
with bilious vomiting,
refusing solids, and
diarrhea.
Findings:
Significant colonic
distension with air-fluid
levels
26. HPI
Unvaccinated 1.5 year old
with a history of
Hirschsprungs presents
with bilious vomiting,
refusing solids, and
diarrhea.
Differential diagnosis?
27. • Toxic Megacolon
• Cdiff
• Salmonella
• E Coli
• Shigella
• Hirschsprung's
enterocolitis
• Viral Gastroenteritis
• Rotavirus
• Constipation
Additional history
She has been afebrile
with normal BP and
HR. Her perfusion in
normal on exam.
28. Day 2:
She was started IVFs,
scheduled rectal irrigations,
and an NG was placed to
decompress her stomach.
She continued to be afebrile
and had a LARGE stool after
ex-lax. Now eating!
29. Day 3:
She is now running around
the exam room. Her stool
culture, Cdiff, and stool
PCR panels are all
negative.
Discharge diagnosis:
Constipation
36. Clinical Pearl: Don’t forget
the B in ABCDE
All lytic lesions should be
referred to hematology &
oncology
ED course: The original
radiologist read only
commented on the
widened mediastinum.
37. ED course:
She was pan-scanned
and was found to have
numerous
Diagnosis?
38. Generalized Lymphatic Anomaly
• Must be confirmed by biopsy
• A systemic lymphatic
malformations disease
• Can present with acute or
persistent pericardial, pleural, or
peritoneal effusions
• Can contribute pathologic
fractures
• Worsens in puberty
• Most importantly, BENIGN
