Abstract

Isolated pure motor weakness of a hand or particular group of fingers usually results from a peripheral neurological disease, although, rarely, it can be caused by central neurological disease,such as cortical infarcts. Weakness of a hand or a particular group of fingers due to cortical cerebral infarction has been described as "pseudo-peripheral palsy." The motor representation ofthe hand in the brain is localized to a knob-like structure in the precentral gyrus. A lesion localized in a region of the hand knob could affect all the muscles of the hand or the muscles innervated by the radial, median, and ulnar nerves. Infarctions in the parietal lobe or white matter ofthe angular gyrus, postcentral gyrus, ventroposterior thalamus, corona radiate, basal ganglia,and posterior limb of the internal capsule can also mimic peripheral nerve lesions. In patients withmonoparesis caused by stroke, cerebral computed tomography can miss infarct lesions. Usingmagnetic resonance imaging can allow the identification of small vascular lesions that cause monoparesis. Early diagnosis of "pseudo-peripheral palsy" is important for adopting a suitable therapeutic approach to prevent a recurrent or larger cortical infarction. We describe 65-year-old patient who presented with an acute paresis of her left hand, suggesting a peripheral nerve lesion.However, on clinical examination, a peripheral origin could not be veri?ed, prompting further investigation. Di?usion-weighted magnetic resonance imaging revealed an acute hemorrhagic lesion. The peripheral nerve pattern of lesions caused by cortical infarcts should be taken into consideration in the differential diagnosis of isolated hand monoparesis.

Özet

El veya parmakların izole saf motor güçsüzlüğü genellikle periferik sinir sistemi hastalıklarınabağlı olarak geliflmesine rağmen nadiren kortikal infarktlar gibi santral sinir sistemi hastalıklarına bağlı oluflabilmektedir. El veya parmakların kortikal serebral infarkta bağlı güçsüzlüğüne 'psödoperiferal palsi' denir. Elin motor temsili presantral girusta bir kabartı fleklindedir. Bu bölgedeki lezyonlar tüm el kaslarını veya radiyal, ulnar ve median sinirin innerve ettiği kasları etkiler.Ayrıca pariyetal lob, angular girus beyaz madde, postsantral girus, ventroposterior thalamus, korona radiate, bazal ganglia, internal kapsülün arka boynuzundaki lezyonlar da periferik sinir lezyonlarını taklit eder. İnmeye bağlı monoparezide Beyin Tomografisi infarkt alanını göstermede yetersiz kalır. Magnetik rezonans görüntüleme küçük vasküler lezyonların neden olduğu infarklarıngörüntülenmesini sağlar. 'Psödoperiferal palsi' tanısının erken evrelerde konması uygun terapötikyaklaflım ile kortikal infarktın büyümesini ve tekrarlamasını önler. Biz bu olgu sunumunda aracılığıyla periferik sinir lezyonunu taklit eden akut sol el parezisi olan 65 yaflındaki hastayı sunduk. Klinik muayene ve bulgular neticesinde periferik sinir lezyonu tespit edilememesi nedeni ile tetkikedilen olgunun magnetik rezonans görüntülemesinde akut hemorajik lezyonu tespit ettik. Bu olgu sunumu aracılığı ile izole el monoparezinin ayrıcı tanısında santral sinir sistemi hastalılarının daakılda tutulması gerektiğini hatırlatmayı amaçladık.
