Abstract
RATIONALE
Plasmacytoma is a disease caused by the proliferation of monoclonal immunoglobulin-producing plasma cells and divided into multiple myeloma, solitary bone plasmacytoma, and extramedullary plasmacytoma. We report a case of orbital extramedullary plasmacytoma invading the dura mater in a patient with exophthalmos and diplopia.
PATIENT CONCERNS
A 35-year-old female patient with exophthalmos in the right eye and diplopia visited the clinic.
DIAGNOSES
The thyroid function tests showed nonspecific results. Orbital computed tomography and magnetic resonance imaging revealed a homogeneously enhancing orbital mass infiltrating the right maxillary sinus and adjacent brain tissue in the middle cranial fossa through the superior orbital fissure.
INTERVENTIONS
To diagnose and alleviate the symptoms, an excisional biopsy was performed, which revealed a plasmacytoma.
OUTCOMES
One month after the surgery, the protruding symptoms and eye movement restriction in the right eye improved, and the visual acuity in the right eye was restored.
LESSONS
In this case report, we present a case of an extramedullary plasmacytoma that originated in the inferior wall of the orbit and invaded the cranial cavity. To our knowledge, no previous reports have described a solitary plasmacytoma that originated in the orbit, causing exophthalmos and invading the cranial cavity at the same time.
