Abstract
Introduction: The medulla oblongata is the lowest segment of the brain stem, located adjacent to the spinal cord, with a complex anatomical structure. Thus, a small injury to the medulla oblongata can show complex clinical manifestations.
Case Presentation: A patient experienced dysesthesia, which manifested as numbness in her right lower limb and decreased temperature sense, and dizziness 20 days before admission. The numbness worsened 1 week before admission, reaching the right Thoracic (T) 12 dermatomes. Her thermoception below the T12 dermatomes decreased, and the degree of dizziness increased, accompanied by nausea and vomiting. Magnetic Resonance Imaging (MRI) of the neck, chest, and abdomen performed at a local hospital showed no abnormalities. MRI of the brain was performed after admission. One week after admission, she experienced a severe headache in the upper left periorbital area. The numbness extended to T4, and thermoception decreased below T4.
Diagnosis: Lateral medullary infarction.
Interventions: Anti-platelet aggregation and mitochondrial nutritional therapies were performed along with treatments for improving circulation and establishing collateral circulation.
Outcomes: The intensity of limb numbness decreased, and the symptoms of headache and dizziness resolved.
Conclusion: Lesions leading to segmental sensory disorders can occur in the medulla oblongata. Ipsilateral headaches with contralateral segmental paresthesia can be a specific sign of lateral medullary infarction.
Keywords: Sensory disturbance, headache, medullary infarction, MRI, medulla oblongata, contralateral segmental dysesthesia.
