Purpose
In this retrospective study we describe the clinical features and orbital imaging of 7 cases where Gallium Dotatate PET was used to help diagnose orbital apex lesions.
Methods
A retrospective review was conducted where Gallium 68 Dotatate PET was used in the management of orbital apex lesions. We analyzed the demographics data, clinical features and radiology to used to make a diagnosis
Results
7 patients were analyzed. 4 cases were positive on Dotatate scan which supports a diagnosis of meningioma.
Conclusion
Orbital apex lesions can often be difficult to diagnose. The usual modality of a biopsy at the apex carries significant risk to sight and is a challenging area to biopsy. With careful selection, Dotatate scans result in a positive result, supporting a diagnosis of meningioma and reducing the need for other investigations and biopsy.
