FFS: Amaurosis fugax
Amaurosis fugax is sudden, painless, transient monocular vision loss from retinal ischaemia—an emergency signalling high stroke risk, requiring urgent carotid evaluation and stroke unit admission
Category Neurology
Transient Ischaemic Attack
TIA is a brief neurological event with high stroke risk. Urgent imaging, specialist review, and early treatment are critical to prevent ischaemic stroke
Neuroimaging Cases 008
Intraventricular rupture of brain abscess (IVROBA). Second in our Neuroimaging case study series with Teresa Crow, Troy Carnwath, Scott DiMeo, L. Erin Miller and Natalie Rall
FFS: Guillain‑Barré syndrome
Acute autoimmune demyelinating polyneuropathy presenting with symmetric ascending weakness, reflex loss, and autonomic symptoms—emergency exclusion of spinal lesions
FFS: Transverse myelitis
Transverse myelitis is a rare neuro-inflammatory disorder of the spinal cord causing motor, sensory, and autonomic dysfunction. Urgent MRI is essential.
FFS: Trigeminal neuralgia
Trigeminal neuralgia is a painful cranial nerve disorder causing brief, intense facial pain. Diagnosis is clinical, with MRI to exclude secondary causes
