Value of Combined Diagnosis for Choroidal Lymphoma: A Case Report.

Intraocular lymphoma (IOL) comprises a group of malignant tumours originating from lymphohematopoietic tissues that have a poor prognosis. These tumours predominantly occur in the vitreous and retina but are rarely found in the choroid. A few case reports and case series of choroidal lymphoma (CL) have been reported in the literature. CL is prone to misdiagnosis and incorrect treatment because it often mimics other intraocular diseases such as uveitis. This may seriously affect localisation of the primary lesion and delay treatment, which may even affect the patient's survival. Herein, we report a case of CL and propose the combination of characteristic ophthalmic imaging with systemic imaging and aqueous humour detection to establish a robust basis for the early diagnosis of CL.
