Orbital pseudotumour : an unusual presentation.

Area of Science:

• Ophthalmology
• Neurology
• Pathology

Background:

• Bilateral orbital pseudotumours are uncommon.
• Intracranial extension of orbital pseudotumours is exceptionally rare.
• Progressive painless visual loss can indicate serious orbital pathology.

Purpose of the Study:

• To report an extremely rare case of bilateral pseudotumour with intracranial extension.
• To highlight the diagnostic challenges and findings associated with this condition.

Main Methods:

• A case study of a 45-year-old male patient.
• Clinical presentation including visual loss.
• Computed Tomography (CT) scan for imaging.
• Repeated biopsy for histopathological diagnosis.

Main Results:

• The patient presented with progressive, painless visual loss.
• CT scan revealed large, hyperdense, enhancing masses in both orbits and around the sella turcica.
• Repeated biopsies confirmed the diagnosis of sclerosing pseudotumour.

Conclusions:

• Sclerosing pseudotumour can present with intracranial extension and significant visual impairment.
• Multimodality imaging and biopsy are crucial for diagnosis.
• This rare entity requires consideration in the differential diagnosis of orbital masses.
