Summary

The Q-tip sign on transesophageal echocardiography is a normal landmark, but pathology can occur in this area. This report highlights two cases where this region, typically overlooked, contained abnormalities.

Area of Science:

  • Cardiology
  • Medical Imaging
  • Anatomy

Background:

  • Transesophageal echocardiography (TEE) is a crucial diagnostic tool in cardiology.
  • The "Q-tip sign" historically represented a potential misinterpretation of normal anatomy.
  • Accurate identification of cardiac structures is vital for diagnosis.

Observation:

  • The "Q-tip sign" is a recognized normal anatomic landmark.
  • This landmark separates the left atrial appendage from the left upper pulmonary vein.
  • In rare instances, pathology may be present in this specific anatomical region.

Findings:

  • Two cases are presented where the "Q-tip sign" area was found to contain pathology.
  • This pathology was initially overlooked due to the area being considered a normal landmark.

  • The findings emphasize the need for careful evaluation of this region.

    • Implications:

    • Clinicians should maintain a high index of suspicion for pathology in the "Q-tip sign" area.
    • This finding may necessitate further investigation beyond routine echocardiography.
    • Enhanced awareness can prevent misdiagnosis and ensure timely treatment.
