[A man with an oppressive sensation behind the orbit]

Area of Science:

• Ophthalmology
• Radiology
• Vascular Imaging

Background:

• Orbital lesions require accurate diagnosis.
• Vascular malformations can present as orbital masses.

Observation:

• A 68-year-old man had a right-sided intraconal lesion.
• The lesion size increased after a CT scan in the prone position.

Findings:

• The positional change in lesion size is characteristic of an orbital varix.
• This imaging finding aids in differentiating vascular anomalies from other orbital pathologies.

Implications:

• Positional CT imaging can be a valuable, non-invasive tool for diagnosing orbital varices.
• Early diagnosis of orbital varices can prevent complications and guide treatment.
• Understanding this diagnostic sign improves the accuracy of orbital imaging interpretation.
