Hemiparesthesias in lacunar pontine ischemic stroke

Abstract

Isolated paresthesia, or paresthesia not accompanied by sensory and/or motor deficits, is an extremely rare manifestation of a cerebrovascular accident. Lacunar pure sensory stroke (PSS) confined to thalamus is characterized by persistent or transient numbness, tingling, pain, burning, or another unpleasant sensation on one side of the body. However, in this condition a sensory loss to all primary modalities in the contralateral face and body is very often encountered. Also previous reported cases of PSS due to lacunar stroke in regions other than thalamus are characterized by the presence of sensory loss together with positive sensory symptoms, none of them reporting isolated paresthesia as the only clinical feature of PSS. We present a case of isolated paresthesia as only clinical manifestation of a lacunar PSS involving both trigeminal and medial lemniscus in dorsal paramedian pontine region. A PSS manifesting with isolated paresthesias may be secondary not only to a thalamic lacunar stroke, but also to a small ischemic lesion confined to both trigeminal and medial lemniscus in dorsal paramedian pontine region.
