“…It is known that pure motor hemiparesis resulting from acute stroke can occur in the PLIC, corona radiata, pontine base and/or ventromedial medulla, with the PLIC being the most frequent site of lesions (5). It has been reported that pure motor monoparesis is rarely caused by lacunar infarctions and that "isolated hand palsy" can be caused by cortical infarctions located in the hand motor area (2,6). To the best of our knowledge, there have been no previous reports of pure motor hemiparesis manifesting primarily as pseudoperipheral palsy caused by a PLIC lesion.…”

Pseudoperipheral Palsy due to Infarction in the Internal Capsule

et al. 2013

Pseudoperipheral palsy can be caused by cerebral cortical infarctions; however, it is rarely caused by lacunar infarctions, including those in the posterior limb of the internal capsule. Meanwhile, the somatotopic localization of the corticospinal tract in the posterior limb of the internal capsule remains unknown. We herein report the case of an 81-year-old Japanese woman who presented with a left hand drop. Brain magnetic resonance imaging revealed an acute infarction as the causative lesion at the inferior level of the anteromedial portion of the posterior limb of the right internal capsule. This case report indicates the topography of hand fibers in the internal capsule.

“…In addition, isolated hand pareses without distinction of the specific nerve side involvement were examined for identification of the motor hand area in the brain. Çelebisoy et al [14] reported that the hand area in the cerebral motor cortex is located in the middle to lower portion of the anterior wall of the central sulcus. Lesions of this region may result in isolated hand paresis.…”

Isolated wrist drop due to stroke is infrequently observed, and often misdiagnosed as peripheral neuropathy. It is important to make the differential diagnosis correctly because drop hand that results from peripheral pathology requires a completely different treatment strategy than central pathology. In addition, small infarcts are important to identify in order to optimise secondary prophylaxis. In this report, we describe an 83-year-old man, with isolated drop hand due to acute small cortical infarction in the left precentral gyrus and present this situation in light of the literature. Key Words: Isolated wrist drop, cortical infarction, precentral gyrus. KÜÇÜK KORTİKAL İNFARKTA BAĞLI NADİR GÖRÜLEN BİR KLİNİK TABLO: İZOLE DÜŞÜK EL ÖZETSerebrovasküler olaylara bağlı gelişen izole düşük el tablosu oldukça nadir görülür ve genellikle periferik sinir lezyonları şeklinde yanlış tanı alır. Tedavi stratejileri tamamen farklı olan santral ve periferik patolojilere bağlı gelişen düşük el ayırıcı tanısı oldukça önmelidir. Ayrıca küçük kortikal infarktların tanınması, özellikle sekonder proflaksi açısından önemlidir. Bu vaka takdiminde, 83 yaşında erkek hasta küçük kortikal infarkt nedeni ile gelişen izole düşük el tanısı ile literature ışığında sunulmuştur. Anahtar Sözcükler: İzole düşük el, kortikal infarkt, presentral girus.

Isolated Shoulder Palsy Due to Infarction of the Cortical Branch of the Anterior Cerebral Artery

An 85-year-old man with essential hypertension and diabetes mellitus abruptly developed right-sided isolated shoulder palsy (ISP). Cranial magnetic resonance imaging demonstrated infarction of the cortical branch of the left anterior cerebral artery (ACA), which involved the left precentral gyrus. In the primary motor cortex, the corresponding area to the shoulder is very small. Consequently, there have been only five reported cases of ISP due to a cortical infarction, and its vascular supply remains uncertain. Our present case denotes that the corresponding area to the shoulder in the primary motor cortex receives its blood from the cortical branch of the ACA.
