Orbital Metastases: When to Suspect? When to biopsy?

Area of Science:

• Ophthalmology
• Oncology
• Radiology

Background:

• Incidental orbital masses are common, often benign, and monitored non-surgically.
• Cancer patients increasingly present with incidental orbital masses during metastasis surveillance.
• Factors like advanced imaging and improved cancer therapies contribute to this trend.

Purpose of the Study:

• To investigate the diagnostic approach for orbital masses.
• To differentiate between benign orbital masses and potential orbital metastases in cancer patients.
• To inform management strategies for orbital masses in both cancer patients and those without a prior cancer history.

Main Methods:

• Review of current literature and clinical guidelines.
• Analysis of diagnostic imaging modalities for orbital masses.
• Discussion of differential diagnoses for orbital masses.

Main Results:

• Orbital masses in cancer patients warrant closer scrutiny for metastasis.
• Distinguishing benign from malignant orbital masses is crucial for appropriate management.
• A systematic approach is necessary for symptomatic orbital masses in all patients.

Conclusions:

• A high index of suspicion for metastasis is needed in cancer patients with incidental orbital masses.
• Appropriate imaging and biopsy may be required for definitive diagnosis.
• Management strategies should be tailored to individual patient history and mass characteristics.
