“…Kim showed that patients with contralateral trigeminal involvement were more likely to have a ventrally located lesion in the brain stem. Conforto et al 10 investigated the correlation between facial sensory abnormalities and lesion topography in eight patients with LMI, and their results showed that contralateral facial sensory abnormalities are related to medial extension of the infarct. In conclusion, sparing the spinal trigeminal tract and its nucleus while disrupting the ventral trigeminothalamic tract accounts for this atypical presentation.…”

SUMMARYLateral medullary infarction (LMI) or Wallenberg syndrome is a type of brain stem stroke, more specifically, a type of crossed brain stem syndrome. LMI is a well-described entity with several documented typical characteristics including pain and temperature impairment in the ipsilateral to the lesion side of the face and the contralateral side of the trunk and limbs. We present a case of LMI which describes a patient who presented with atypical features of analgesia and thermanaesthesia on the contralateral side of the face and absence of sensory deficit on the ipsilateral side. We attributed this pattern of involvement to a lesion that affects the ventral trigeminothalamic tract and spares the dorsolateral part of the medulla where the spinal trigeminal tract and its nucleus lie. This case report highlights the presence of atypical presentations of LMI that may initially challenge the physician's diagnostic reasoning. BACKGROUND

BackgroundDorsolateral medullary infarction (Wallenberg Syndrome) is rare in clinical practice; however, the subsequent corneal lesions are more uncommon. To our knowledge, only one such case was previously reported. We report a similar case with successful treatment and recovery, and analyse both cases to address the clinical features and outcomes of such syndrome.Case presentationA 43-year-old male presented with neurotrophic keratopathy one month after sustaining dorsolateral medullary infarction. The patient underwent amniotic membrane transplantation twice. Two-year follow-up observation revealed changes in nerve fibers and epithelial cells of corneal by laser confocal microscopy.ConclusionBy studying both cases, we confirm that neurotrophic keratopathy could be as a delayed-onset complication of Wallenberg syndrome. The recognition that neurotrophic keratopathy can follow dorsolateral medullary infarction could prevent the clinical misdiagnosis.
