Summary

Calcium embolism, a rare stroke cause, is diagnosed via CT scans showing calcified material in brain arteries. Observing the calcified material migrate confirms this uncommon condition.

Area of Science:

  • Neurology
  • Radiology

Background:

  • Calcium embolism is an infrequent cause of stroke, often undiagnosed without cardiac surgery or catheterization.
  • Emboli originate from cardiac valves or calcified atheroma in the aorta or carotid arteries.

Observation:

  • Two patients presented with cerebral infarcts due to spontaneous calcium embolism.
  • Neuroimaging, specifically CT scans, revealed dense points of calcified material within cerebral arteries.

Findings:

  • CT scans are crucial for diagnosing calcium embolism.
  • The migration of calcified material along the artery confirmed the diagnosis in one case.

Implications:

  • Cranial CT scans are essential for diagnosing calcium embolism.
  • The necessity of valve replacement and the use of antiplatelets/anticoagulants remain uncertain.
  • Further research is needed to establish optimal treatment strategies for calcium embolism.
