Tumors masquerading in patients with thyroid eye disease

Area of Science:

• Ophthalmology
• Endocrinology
• Oncology

Background:

• Thyroid eye disease (TED) is the leading cause of adult proptosis.
• TED diagnosis is typically clinical, often without imaging.
• Orbital tumors mimicking TED are reported, but late-onset tumors in TED patients are less documented.

Observation:

• This study presents a 6-year retrospective analysis of three patients.
• All patients had a history of long-standing TED.
• Each patient developed an initially unsuspected orbital or cavernous sinus tumor.

Findings:

• The cases highlight the challenge of differentiating new orbital pathology from chronic TED.
• Orbital tumors can arise years after the initial TED diagnosis.
• Diagnostic imaging may be crucial in long-standing TED cases with new or worsening symptoms.

Implications:

• Clinicians should maintain a high index of suspicion for orbital tumors in patients with long-standing TED.
• Further research is needed to understand the relationship between TED and secondary orbital tumor development.
• This underscores the importance of vigilant follow-up and appropriate investigations in managing TED patients.
