Differential Diagnosis for Patient with Artery Blockage when Turning Head

  • Single most likely diagnosis:
    • Rotational vertebral artery occlusion: This condition occurs when the vertebral artery is compressed or occluded due to rotation of the head, leading to transient symptoms such as dizziness, vertigo, or even stroke. The symptoms are directly related to the mechanical obstruction of the artery during head movement.
  • Other Likely diagnoses:
    • Carotid artery stenosis or dissection: Although less directly related to head turning, significant stenosis or dissection of the carotid artery can lead to symptoms that worsen with certain head positions due to altered blood flow or embolism.
    • Cervical spondylosis with vertebral artery compression: This condition involves wear and tear on the discs in the neck, which can lead to compression of the vertebral arteries, especially during certain movements.
  • Do Not Miss diagnoses:
    • Stroke or transient ischemic attack (TIA): It is crucial not to miss the diagnosis of an acute stroke or TIA, as timely intervention is critical for outcomes. Symptoms can sometimes be precipitated or worsened by head movements.
    • Vertebral artery dissection: This is a serious condition where the inner layer of the vertebral artery tears, potentially leading to stroke. It can be triggered by neck movements and must be promptly diagnosed and treated.
  • Rare diagnoses:
    • Fibromuscular dysplasia: A rare condition that affects the medium and large arteries, most often the renal and internal carotid arteries, but can also involve the vertebral arteries. It can cause stenosis, aneurysms, or dissections and might lead to symptoms during head movements due to altered blood flow.
    • Eagle syndrome: A condition characterized by an elongated styloid process or calcified stylohyoid ligament, which can compress the carotid arteries or adjacent structures, potentially leading to symptoms that could be exacerbated by head turning.
