Summary
Gallium-67 citrate imaging revealed persistent intense activity in an orbital pseudotumor, a rare finding. This case highlights gallium imaging
Area of Science:
- Ophthalmology
- Nuclear Medicine
- Radiology
Background:
- Orbital pseudotumors can present with symptoms like proptosis, diplopia, and gaze palsy.
- Diagnostic imaging is crucial for the early identification of orbital disorders.
Observation:
- A patient with an orbital pseudotumor exhibiting proptosis, diplopia, and gaze palsy underwent Gallium-67 citrate imaging.
- Persistent intense activity was observed on the Gallium-67 scan for five days.
Findings:
- This case may represent the first reported instance of gallium uptake in an orbital pseudotumor.
- Gallium-67 citrate imaging demonstrated significant and sustained activity within the orbital lesion.
Implications:
- Gallium-67 citrate imaging can be a valuable tool in the early diagnostic workup of orbital pseudotumors.
- This imaging modality may aid in differentiating orbital pseudotumors from other orbital pathologies.
