A case of sequential limb weakness.

neurology

consulted for limb weakness 

allergic to ciprofloxacin

chronic smoker for 50 years, non-drinker

PMH: LUTS, right renal stone with OT 

case of cystitis / prostate abscess complicated with septic shock, AKI, ARDS, Waterhouse-Friderichsen syndrome

history clarified with patient and wife: 

acute onset left hand numbness (radial 4 fingers + palm) 23/9 pm, did not notice left hand weakness, still able to complete his work as a driver that day 

attended AED 24/9 for the left hand symptoms (AED notes documented the attendence was for upper back pain), WCC 16 neutrophilia, dispensed tramadol / maxolon 

developed generalized malaise after taking meds from AED, sleeping throughout most of the day 25-27/9

accompanied wife to china for dental checkup 28/9 am, acute worsening of patient’s consciousness at 2pm that day, noted to be poorly responsive with generalized weakness at SZB while returning to HK, attended by staff and found to be febrile, sent to AED  

no unilateral weakness / facial asymmetry / diplopia / dysphagia / sphincter disturbances / prior cognitive impairment 

no headache / neck pain / seizure / OTC meds / herbs 

on admission SBP 130, HR 110, 38C, RA, hstix 6.6, GCS and limbs power full

WCC 15 eosinophilia, LRFT INR N, CRP 200, blood urine c/st -ve

29/8: seen by neurology for left IF flexor weakness, no other focal weakness, imp: suspected left AIN palsy

31/8: wife noted patient to have decreased verbal response, slurred speech, poor oral intake, and decreased right side limb movement since 30/8 during visiting hours

PE: GCS full, right > left 4 limb weakness (R 4/3; L 5/4) with right facial weakness and slurred speech; SBP 120, fever 38C

CTB: right posterior watershed patchy hypodensities

right hemiplegia trough at 0/5 

1/9: complicated with septic shock required ICU support and high dose inotropes; CT A+P: prostate abscess / cystitis; AKI, ARDS; stabilized and discharged to general ward 10/9

17/9: ORT: left proximal median nerve palsy

23/9: acute onset left lower limb weakness (R 4/3; L 4/4-), PR tone grip sensation normal, serial CTB: interval established right posterior watershed and left pontine infarct, ventricular size static 

CXR: no cardiomegaly 

ECG: SR, no LVH

A1c 6.3, LDL 0.9

echo: unremarkable 

holter: no AF

ESR / CRP normalized 

TP EIA HIV -ve 

lactate N 

GCS full 

no ptosis, PEARL, EOM / saccades normal, right UMN facial weakness

4+/5-

proximal 3, distal 4+ / proximal 4+, distal 5 

bilateral pyramidal weakness R>L 

right pronator drift, right UL overshoot

tone normal 

generalized hyporeflexia, no ankle clonus, flexor plantar responses 

no sensory level 

no dysmetria / disdiadochokinesia 

gait: narrow based, failed tandem walking, romberg -ve 

left hand

impaired thumb / index finger flexion on making a fist 

unable to perform the ok sign or thumb / LF opposition

finger long flexor weakness across the ulnar 4 fingers  

finger abduction weakness, froment +ve

finger extension weakness, wrist extension power full  

imp: 

acute onset left IF weakness; acute onset right hemiplegia with right facial weakness; acute onset left LL weakness; symptoms were worst at onset with interval recovery 

in the clinical context of prostate abscess with severe septic shock 

CTB showed interval development of right posterior watershed and left pontine wedge shaped hypodensities with grey white involvement 

the clinical presentation was likely compatible with recurrent acute ischemic stroke involving different vascular territories 

the likely stroke etiology may be a perfusion infarct in the setting of severe systemic hypotension on top of possible large vessel disease; ddx embolic 

RF: chronic smoker, no other known vascular risk factors  

left hand examination demonstrated deficits beyond in the left median nerve to involve the left ulnar and radial nerve innervated muscles; taking note that findings at this juncture can be overshadowed by the left sided ischemic stroke 

suggest 

– await contrast MRI brain / MRA head and neck to clarify the diagnosis and exclude alternative infective / inflammatory pathology given the atypical presentation, red flag (concurrent severe systemic sepsis), and recurrent neurological symptoms

– review the need for further embolic stroke workup after large vessel disease excluded

– await NCT / USG left forearm to clarify the presence of a concomittant peripheral neuropathy
