Abstract:
Medullary infarct is still little known influencing the short-term vital and functional prognosis of patients. Medullary vascularization is one of the most complex in the body due to the significant number of arteries that contribute to it. Our knowledge is still limited due to the scarcity of vascular medullary accidents and to low accessibility of medullary vessels during assessments. We report the case of a 62-year old patient with type 2 diabetes and a 13-year history of oral antidiabetic treatment who had been followed-up for psoriasis for 4 years. He presented to hospital in the night with his son due to acute onset of upper limb deficit. This deficit was preceded by acute onset of neck pain during his daily prayer. On admission, the patient was conscious, arterial pressure 120/86mmhg, heart rate 89 beat/min, afebrile. Clinical examination showed flaccid brachial diplegia. There was no sensory disorder or sphincteric disorder and cranial nerve examination was normal. Emergency medullary MRI was performed which showed T2 hyperintense signal and "snake-eyes"-like bilateral central dissemination (A and B). Etiological assessment showed therosclerotic patches at the origin of the left internal carotid artery. The diagnosis of myocardial infarct associated with medullary fibrocartilaginous embolism was retained. Functional rehabilitation was started early as well as treatment with platelet aggregation inhibiting drugs.
Insights
A rare medullary infarct case highlights the complexity of spinal cord vascularization. Early diagnosis and treatment are crucial for patient prognosis.
Area of Science:
- Neurology
- Vascular Medicine
- Radiology
Background:
- Medullary infarcts are poorly understood, impacting patient prognosis.
- Spinal cord vascularization is complex, with limited research on medullary vascular accidents.
- Accessibility of medullary vessels for assessment is challenging.
Observation:
- A 62-year-old male with type 2 diabetes presented with acute upper limb deficit and neck pain.
- Clinical examination revealed flaccid brachial diplegia.
- Medullary MRI demonstrated a characteristic "snake-eyes" T2 hyperintense signal.
Findings:
- The patient was diagnosed with myocardial infarct and medullary fibrocartilaginous embolism.
- Etiological assessment revealed atherosclerotic patches at the left internal carotid artery origin.
- The "snake-eyes" sign on MRI is indicative of specific medullary infarct patterns.
Implications:
- This case underscores the importance of considering medullary infarct in acute neurological deficits.
- Prompt diagnosis via MRI and etiological investigation are vital.
- Early functional rehabilitation and antiplatelet therapy are recommended for improved outcomes.
