17. Masseter reflex abnormalities with meso-diencephalic lesions
2012
different papers and some eponyms used to characterize a certain neurological state differ from the original description. Except for Wallenberg‘s syndrome, classical brainstem syndromes are rarely seen in clinical practice. Lacunar brainstem syndromes are the consequence of infarcts, which involve long tracts and spare intra-axial cranial nerve segments. This group includes pure motor or pure sensory stroke, dysarthriaclumsy hand syndrome, or ataxic hemiparesis. Such infarcts may also cause body lateropulsion with or without limb ataxia, internuclear ophthalmoplgia, skew-torsion sign, or ocular tilt reaction. Small deep infarcts, which solely affect certain nuclei, may be followed by horizo…
Chapter 15 Pain and itch in Wallenberg's syndrome: anatomical–functional correlations
2006
Publisher Summary The Wallenberg syndrome or dorso-lateral medullary infarction is the most common vascular syndrome of the medulla oblongata. Its clinical features include an ipsilateral Horner's syndrome, an ipsilateral limb ataxia, and mostly an ipsilateral but sometimes also a contralateral or bilateral decrease of pain and temperature sensibility of the face. Patients with Wallenberg's syndrome and with morphological (lesion) or functional (ipsilateral sensory deficit and delayed late blink reflex responses) show evidence of damage to the trigeminal tract and nucleus with sparing of the nucleus caudalis would develop facial pain. The trigeminal trophic syndrome (TTS), a very rare compl…
A topodiagnostic investigation on body lateropulsion in medullary infarcts.
2005
Body lateropulsion may occur without signs of vestibular dysfunction and vestibular nucleus involvement. The authors examined 10 such patients with three-dimensional brainstem mapping. Body lateropulsion without limb ataxia reflected an impairment of vestibulospinal postural control caused by a lesion of the descending lateral vestibulospinal tract, whereas body lateropulsion with limb ataxia was probably the consequence of impaired or absent proprioceptive information caused by a lesion of the ascending dorsal spino-cerebellar tract.
