Case 20: 7yo - Headaches Flashcards

1
Q

Headaches: when would you admit? what would you do for mgmt?

A
  • intractable vomiting (esp. when awakening) ==> head-occupying tumor [non-contrast head CT]
  • complex migraine + focal weakness
  • intractable pain
  • URI ==> leading to fever == sinus abscess [contrast CT]

Other signs that this is NOT migraine/cluster/tension ==> and you should admit

  • swelling
  • fever / infectious signs
  • bleeding
  • dehydration ==> DVTs in the brain == HA +/- facial swelling

A Headache accompanied by projectile vomiting.
B Sudden onset of severe headache.
C Headache that awakens one from sleep.
D Headache associated with fever and photophobia.
E Headache that worsens with cough or Valsalva maneuver.
F Intermittent headache, relieved by nonsteroidal anti-inflammatory drug.
G Headache occurring early in the morning.

A

everything except F = HA that have persisted for a long time without change are not as concerning.

b/c they CAN be due to migraines

but can also be due to scary reasons.

54
Q

questions to consider during history taking of HA

A

OLDCARDS

  • time of day
  • other problems around the time of the HA
  • brings on theHA
  • do they cause waking up in the middle of the night
  • does coughing or bending over to pick something up while you have a HA make it worse?
  • hx of trauma (+/- LOS, emesis)
  • stressors at home / school
  • trouble sleeping
  • ROS: fever, neck stiffness, change in vision / photophobia during the HA; gait; clumsiness/falling more than usual; dizziness
55
Q

why is it important to assessment development when a kid has migraines?

A
  • nml development is reassuring but does not exclude serious pathology
  • abnml development ==> concerns for potential relationship between developmental delay and the HA (with temporal relationship between delay and HA)
56
Q

A

diagnosis of exclusion

  • epidemiology = mostly young girls
  • patho = increased ICP in the absnce of intracranial mass lesion / hydrocephalus ==> d/t alterations in CSF absorption and/or production; abnomalities in vasomotor control & cerebral blood flow
  • etiology = obesity, meds (vitA, tetracycline, OCPs, steroids), metabolic d/o (galactosemia, hypoPTHism), infections (sinusitis, chronic otitis media)
  • sxs (mimics increased ICP) = HA, vomiting, diplopia (d/t paralysis of abducens nerve)
  • dx == elevated CSF on lumbar puncture
    1) increased ICP + HA, vomiting
    2) normal brain anatomy
    3) normal CSF
  • complications = blindness d/t transmission of elevated CSF pressure to optic nerve sheath
59
Q

presence of nystagmus indicates?

A

nystagmus = rhythmic oscillation of the eyes (~ tremor)

can be horizontal/vertical/rotary
==> sign of cerebellar disease

diffdx

  • tumors (nystagmus TOWARD the side of the lesion)
  • toxins
  • cerebellitis
  • multiple sclerosis
60
Q

what is periodic alternating nystagmus?

61
Q

lesion in cerebellum: vermis (midline)

A

dysarthria, truncal ataxia, and gait abnormalities

62
Q

lesion in cerebellum: hemispheric

A

ipsilateral limb abnormalities, nystagmus, tremor/dysmetria and tend to spare speech.

fall to the side of the lesion; worse nystagmus when they look toward the side of the lesion

63
Q

lesion in cerebellum: deep cerebellar nuclei

A

resting tremor, myoclonus, and opsoclonus such as that seen in children with a neuroblastoma

64
Q

“What if, on Nick’s neurologic examination today, you’d found that he had papilledema, paresis and sensory loss over the right leg with 4+ reflexes at the patella and ankle also on the right—and that the rest of his neurologic examination was normal. With those findings, where would you think the lesion might be?”

Multiple Choice Answer:
A Supratentorial, on the right side of the brain
B Supratentorial, on the left side of the brain
C Infratentorial on the right side of the brain
D Infratentorial on the left side of the brain
E Brain stem

A

B

Nick is 7yo –> more likely to be supratentorial

supra = contralateral
infra / cerebellar = ipsilateral

65
Q

A 7-year-old boy presents with a five-year history of intermittent vomiting, vertigo, and throbbing unilateral headaches that seem to be induced by emotional stress and when his teacher wears perfume. He reports that the pain is not worsened by long naps or coughing. His mother reports that she has a history of headaches that started as a child and wonders if her son inherited this from her. His neurological exam shows no focal deficits. What is the next step in diagnosis or treatment?

A Trial of prophylactic medication for migraine headaches
B MRI
C NSAIDs
D Referral to an ENT surgeon

A

A

throbbing = migraines

signs of both typical and atypical migraines and could be started on a trial of prophylactic medication. Tricyclic antidepressants (TCAs) are often used in children for migraine prophylaxis, which is the most likely diagnosis in a child with this constellation of symptoms.

NSAIDS = good for abortive therapy for migraines; but more often used for tension HA.

66
Q

A 7-year-old boy with a past medical history of headaches presents with increased frequency and severity of headaches along with new onset vomiting. When the patient was walking into the room, he had a wide stance and nearly tripped twice. Which of the following is the most appropriate next step?

A		Daily headache diary	
B		Computed tomography	
C		Magnetic resonance imaging	
D		Lumbar puncture	
E		Intraventricular pressure monitoring
A

C

RED FLAGS (such that watchful waiting would be wrong)

increasing severity
+ ataxia

NO LUMBAR PUNCTURE in those who seem to have increased ICP (vomiting, possible pass effect) ==> concerns of herniation

CT is not as good at MRI at visualizing posterior fossa

67
Q

A 3-year-old girl presents to the ED with sudden onset difficulty walking. She does not have a fever, headache, nausea, or vision changes, but two weeks ago she had a runny nose, a fever, and a rash. Musculoskeletal exam reveal no abnormalities of lower extremities. Neuro exam reveals bilateral horizontal nystagmus, wide based stance and swaying, and bilateral overreaching on finger to nose test. An LP is performed which reveals a normal CSF. Which of the following is the most likely diagnosis?

A		Opsoclonus-myoclonus syndrome	
B		Hydrocephalus	
C		Infectious cerebellitis	
D		Post-infectious cerebellitis	
E		Migraine headache
A

D
typically presents in a younger child with ataxia, nystagmus, vomiting and sometimes dysarthria. It is believed to be an autoimmune response leading to demyelination of the cerebellum occurring several weeks after a viral infection such as varicella or coxsackie virus

68
Q

A 12-year-old girl presents to her PMD complaining of a headache of gradual onset x 3 hours, non-provoked and described as a “big rubber band around my whole head” and a 5 out of 10 on the pain scale. The pain is not throbbing, and there is no associated photophobia, nausea or vomiting. The patient is afebrile, and there are no neurologic deficits during physical exam. Her mother states her pain is typically relieved with ibuprofen, but her mother is concerned that patient may have migraines because she has a few headaches every month after school. The child is otherwise healthy. What is the most likely cause of this girl’s headaches?

A		Migraine	
B		Tension-type headache	
C		Brain tumor	
D		Sinusitis	
E		Pseudotumor cerebri
A

B

tension headache, helped with NSAIDs.

bilateral and involve the forehead, temporal areas, or back of the head. Tenderness of the posterior muscles of the neck may also be present. They should be responsive to NSAIDs. Stress can give rise to a tension headache, and this is consistent with this patient developing headaches after school
