What's my lucky number?
Eyes open to voice, incomprehensible speech and localizes pain
What is GCS 10
Absence of pyramidal tract findings, but includes
(1) vertigo, nystagmus, diplopia
(2) ipsilateral facial paresthesia, ataxia, Horners syndrome, dysphagia, hoarseness, diminished gag, body numbness
(3) contralateral loss of body pain and temperature
What is lateral medullary syndrome (AKA Wallenberg's syndrome, AKA "PICA syndrome" although usually involves vertebral artery too)
Acute onset peripheral neuropathy with more severe proximal muscle weakness and little or no sensory involvement - often following a viral illness
What is Guillain-Barre syndrome
Refers to a situation with the posterior cerebral artery where there is a hypoplastic P1 segment, so that the blood supply to P2 is from the ICA rather than the basilar artery
What is a "fetal" posterior communicating artery
The most common cause of failure (incomplete) surgery for carpel tunnel syndrome
What is incomplete division of the proximal portion of the flexor retinaculum
Medium sized AVM (3-6 cm) in eloquent brain with deep venous drainage
What is Spetzler-Martin Grade 4
Locked in syndrome
What is bilateral pure motor hemiparesis typically from pons infarct (sometimes cerebral peduncles or pyramids)
Weakness, atrophy and fasiculations, particularly in the upper extremities, with no cognitive, sensory or autonomic dysfunction
What is amyotrophic lateral sclerosis
A large lenticulostriate vessel contained within the lamina terminalis cistern. Rhoton found it arising from the proximal A2 segment in 78%, distal A1 14% and A. comm in 8%
What is the recurrent artery of Huebner
A branch of the median nerve arising from its radial side that crosses the wrist above the transverse carpel ligament and can be damaged with tranvserse wrist incision or if the standard incision for carpel tunnel release is made too lateral, causing a painful neuroma
What is the palmar cutaneous branch
Non-traumatic SAH with localized clot and /or vertical layer > 1 mm on CT
What is Fisher grade 3
Includes loss of taste posterior 1/3 tongue, vocal cord / palate paralysis, and weakness of the SCM and trapezius
What is Vernet's syndrome (AKA the most common Jugular Foramen Syndrome)
(1) loss of taste posterior 1/3 tongue (IX); (2) vocal cord and palate paralysis (X); weakness of the SCM and trapezius (XI)
An acute non-traumatic spinal cord pathology which may be post-infectious, autoimmune or idiopathic
What is acute transverse myelitis
Runs posterinferiorly in the confluence of the falx cerebri to usually terminate in the left transverse sinus at the internal occipital protuberance
What is the straight sinus
The contents of the carpel tunnel
What are the median nerve and 9 flexor tendons (4 tendons of FDP, 4 tendons of FDS and the tendon of the FPL)
Obvious weakness and/or disfiguring asymmetry to the face
What is House-Brackmann Grade 4
The most common inherited peripheral neuropathy
What is Charcot-Marie-Tooth syndrome (peroneal muscular atrophy)
An often systemic granulomatous disease that primarly involves the leptomeninges and typically causes cranial nerve palsies. Extracranial involment may produce peripheral neuropathy and myopathy
What is neurosarcoidosis
This structure arises from the deep middle cerebral vein / anterior cerebral vein and joins the vein of Galen in the quadrigeminal cistern
What is the Basal Vein of Rosenthal
Key muscle innervated by tibial nerve to distinguish foot drop from common peroneal nerve palsy versus L4/5 radiculopathy
What is foot inversion (weakness of tibialis posterior, innervated by tibial nerve, may be due to L4 or L5 radiculopathy)
Burst lumbar fracture with suspected disruption of the posterior ligamentous complex and cauda equina syndrome
What is TLICS 7
Weber's syndrome
What is a cranial nerve III palsy with contralateral pure motor hemiparesis (no sensory loss) - central midbrain infraction usually due to occlusion of interpeduncular branches of basilar artery (affects cerebral peduncle and fibres of III). May be due to aneurysm of basilar bifurcation or BA-SCA junction
A paraneoplastic syndrome which causes presynaptic neuromuscular junction (PSNMJ) blockade due to antibodies against the PSNMJ (i.e., a myasthenic syndrome, most often seen in primary lung cancer)
What is Eaton-Lambert syndrome
Three branches that arise from the meningohypophyseal trunk
What are (1) artery of tentorium (Bernasconi and Cassinari); (2) dorsal meningeal artery; (3) inferior hypophyseal artery
"Finger drop" without full "wrist drop" is seen in this entrapment neuropathy
What is posterior interosseous nerve entrapment
