[Unilateral exophthalmos as the debut of a non-secretory multiple myeloma].

CASE REPORT A 56 year-old male presented blurred vision and diplopia for 2 months, left unilateral exophthalmos, restricted ocular motility and papilledema. The imaging proofs showed osteolytic lesions in the left sphenoid bone, fourth rib and fourth dorsal vertebral body with associated masses of soft tissues. Biopsy was performed and the diagnosis of plasma cell neoplasm was established. The diagnosis of non-secretory multiple myeloma was made by analytical criteria and bone marrow biopsy. Local radiotherapy and polychemotherapy was prescribed. CONCLUSIONS The ophthalmologist can play an important role in the diagnosis of systemic neoplasms that require the intervention of a multidisciplinary team.
