Abstract
Purpose :
To report a case of rare primary diffuse large B-cell lymphoma arising from the sphenoid sinus initially manifesting as binocular diplopia
Methods :
Observational case report. Spectral domain optical coherence tomography (SD-OCT), automated visual field testing, magnetic resonance imaging (MRI), and computed tomography (CT) were used to assist in diagnosis and management.
Results :
A 57-year-old Asian male patient with remote history of tobacco use presented to clinic with two weeks of binocular diplopia and mildly diminished visual acuity of his right eye. He was diagnosed with sixth nerve palsy versus skew deviation and recommended to follow closely; however, his visual acuity continued to diminish and an afferent pupillary defect was noted. MRI performed in tertiary care hospital revealed a mass arising from the sphenoid sinus with orbital and intracranial extension, encasing the right optic nerve. Subsequent biopsy of the lesion identified diffuse large B-cell lymphoma. After treatment with high dose steroids and chemotherapy induction, visual acuity improved and the patient remains under close multidisciplinary management.
Conclusions :
Primary diffuse large B-cell lymphoma of the sphenoid sinus is a rare neoplasm and an extremely uncommon cause of unilateral oculomotor nerve palsy. Previous reports of this entity have not been described in the ophthalmic literature.
