Clinical- 6 Flashcards
Which nerve innervate the anterior/middle fossa?
V
Which nereves supple the posterior fossa?
IX and X
What are the common causes of acute headaches?
SOMATIC DYSFUNCTION UP IN THIS BITCH Subarachnoid Hemorrhage Other Cerebrovascular diseases Meningitis/encephalitis Ocular Diseases (glaucoma)
What are the common causes of Subacute headaches?
Giant Cell (temporal) arteritis Intracranial Mass (tumor, subdural hematoma, abcess) Pseudotumor cerebri (benign intracranial hypertension) Trigeminal neuralgia Glossopharyngeal neuralgia Postherpetic neuralgia Hypertension Atypical Facial Pain
What are the common causes of chronic headaches?
Migraine Cluster Headache Tension headache Cervical Spine Disease Sinusitis Dental Disease
Subarachnoid hemorrhage (SAH)- causes
ruptured berry aneurysm from sites of branching arteries. can be from AV malformations too. polycystic kidney disease is assocaited with berry aneurysms
SAH- Sx
Worst headache ever. new headache. ↑ BP, global Sx (except AVMs and PCA aneurysms).
SAH- Dx
CT for confirmation, CSF has blood, u can do a cerebral arteriography
SAH- Tx
↓ BP. Nimodipine blocks Ca channels to reduce vasospasm. Surgery for mild cases
SAH- complications
recurrence, intraparenchymal extension, ischemia from arterial vasospasm, hydrocephalus, szrs
SAH- prognosis
60% die within the 1st day, but survivors can be either in a coma or Sx free. 1/2 have brain dmg.
Giant cell arteritis (GCA)- cause
granulomatous inflammation of the external carotids (sup temporal a.), women > 55
GCA- Sx
pain in jaw during chewing, blindness in 50% of pts
GCA- Dx
Bilateral biopsy for patchy inflammation, ESR is ↑↑↑
GCA- Tx
initially it’s prednisone (antinflamm)
GCA- consequences
blindness is irreversible
Intracranial mass- Sx
headaches with different Sx depending on where the mass is and what the mass it.
Key: bifrontal pain, worse ipsilaterally, worse when u change position, worse when you INCREASE ICP (pooping, sneezing, coughing)
Intracranial mass- Dx
CT/MRI right away
Intracranial mass- Tx
removal of the offending lesion via surgery, radiotherapy, chemotherapy.
Idiopathic intracranial HTN (IIH)- cause
unknown, so u gotta rule out other disorders that cause intracranial HTN
