Orbital involvement in multiple myeloma is unusual. We describe the case of a 60-year-old male who presented with left proptosis, reduced visual acuity, diplopia and progressing signs of globe indentation 2 months after chemotherapy for multiple myeloma. MRI showed a well-defined tumor filling the mediobasal part of the left orbit. Incisional biopsy and reduction of tumor mass were performed using an anterior transconjunctival orbitotomy. Histopathologic findings and further systemic examination confirmed the reactivation of the multiple myeloma. Proptosis, intraocular pressure and visual acuity improved following external beam radiation therapy of the left orbit and repeated systemic chemotherapy. Orbital involvement in multiple myeloma was the only sign of insufficient chemotherapy.

We report the case of a 39-year-old man who consulted for severe exophthalmia with diplopia associated with chronic sinusitis evolving over 6 months. A cervicofacial CT scan showed a tumoral mass invading the maxillary and ethmoidal left sinus and orbital cavity. A biopsy of the mass and general evaluation confirmed the diagnosis of extramedullary plasmocytoma. Secondarily it transformed into multiple myeloma. In light of this case of extramedullary plasmocytoma in a young subject, we discuss the clinical characteristics, ophthalmologic manifestations, and the various therapeutic modalities according to the stage of the disease and the ocular repercussions.

Skull base involvement of plasmacytoma is reported in a patient with light chain myeloma. A 39-year-old man was admitted after experiencing paresthesia on the left side of the face and left arm, intermittent diplopia, and hoarseness for 2 years. Cranial magnetic resonance imaging revealed a large midline mass extending from the middle and posterior skull base into the upper two cervical vertebrae. An extramedullary plasmacytoma associated with light chain multiple myeloma was diagnosed after biopsy of the mass and laboratory investigations. The imaging findings and clinical features associated with this rare site of extramedullary plasmacytoma involvement are reported.

Plasma cell neoplasms of the head and neck region can be extramedullary plasmacytoma of the bone, solitary plasmacytoma of the bone, and local manifestations of multiple myeloma. A 70-year-old male patient was admitted to our hospital with diplopia of four-day history. Magnetic resonance imaging showed soft tissue in the sphenoid sinus. Endoscopic biopsy was taken from the sphenoid sinus, which revealed multiple myeloma. Despite medical therapy for multiple myeloma, the patient died after a year.

We report on a 70-year-old male who developed cavernous sinus syndrome as the initial symptom of multiple myeloma. He was admitted with diplopia and ptosis in October 2004. The diagnosis of multiple myeloma and cavernous sinus syndrome due to a gross mass at the sinus base were made. Cerebral computed tomography revealed that the lesion occupied the sphenoid sinus and involved the oculomoter nerve. He underwent local irradiation of the mass followed by systemic chemotherapy. The symptoms caused by the mass disappeared after the treatment. Clinicians need to be aware of the rare manifestation of multiple myeloma.

A 60-year-old male presented with headache and diplopia for 2 months. Computed tomography of the head showed a heterogeneously enhancing expansile lytic lesion in clival region. The patient underwent surgery and histopathological examination revealed it to be plasmacytoma of the clivus. The multiple myeloma work-up was negative. Solitary plasmacytoma localized to the skull base is extremely rare. Prior to this, only three case reports of plasmacytoma of the clivus have been described in the English literature.

A 58-year-old previously healthy man presented with diplopia of rapid onset over a few days. Examination demonstrated bilateral sixth and right fourth cranial nerve palsy. MR imaging showed a large sellar mass with significant destruction of the pituitary fossa. Laboratory tests revealed very high serum prolactin (2,483 ng/dl, reference range 3-13 ng/dl). Dopamine agonist therapy was initiated with significant decline in PRL levels; however, nausea, fatigue, and anorexia developed. Within a few weeks the patient developed renal failure and hypercalcemia. Urine protein electrophoresis revealed large free monoclonal kappa peaks while extensive plasmocytosis was evident in bone marrow aspirates. On bone scan numerous lytic lesions were present. A transsphenoidal excisional biopsy was performed which demonstrated two distinct populations of cells, corresponding to a plasma cell tumor and a lactotroph adenoma. Treatment for multiple myeloma was initiated along with radiotherapy for the sellar tumor. Only a few cases of solitary plasmocytomas of the pituitary region have been reported. Few cases of prolactinomas coexisting with other sellar tumors has been described. We discuss in this report possible pathogenic and functional connections between these two tumors. We suggest that in the presence of extensive cranial nerve involvement, atypical imaging findings for a pituitary adenoma and severe hyperprolactinemia, the possibility of a collision tumor should lead the physician to consider excisional tumor biopsy or surgery in addition to dopamine agonist therapy.

We report a case of multiple myeloma that presented as a fluctuating sixth cranial nerve palsy in the absence of widespread signs of systemic disease. A 63-year-old woman presented with horizontal diplopia of two weeks duration that subjectively changed over time. Ocular examination showed a fluctuating sixth nerve palsy. A computed tomography (CT) scan of the brain showed multiple, enhancing, soft tissue, mass-like lesions involving the left cavernous sinus and the apex of both petrous bones. Based on bone marrow biopsy and hematologic findings, she was diagnosed with multiple myeloma. Multiple myeloma may be included in the differential diagnosis of a fluctuating sixth nerve palsy, and although ophthalmic signs are rare and generally occur late in the course of multiple myeloma, they can still be its first signs.

The authors report a case of orbital plasmacytoma in a 48-year-old man with known multiple myeloma. He presented with proptosis, diplopia, and decreased vision of the left eye for several weeks. He had been previously treated for IgA lambda multiple myeloma with chemotherapy, radiation, and autologous stem cell transplant. After a left orbitotomy, flow cytometry revealed a tumor rich in plasma cells expressing CD138 with equivocal lambda light chain expression. The patient underwent orbital radiation, with improvement of vision and disc edema OS. The patient is currently undergoing salvage chemotherapy for relapse of multiple myeloma. This is the third reported case of IgA myeloma involving the orbit.

Autologous stem cell transplantation (ASCT) can prolong remission duration, overall and progression free-survival in multiple myeloma (MM). Ocular relapse is rare in MM. Here we present a patient with only ocular relaps and without evidence of bone marrow progression after ASCT. Ig A kappa myeloma, stage IIIA was diagnosed in a 53-year-old man, according to Kyle-Greipp and Durie Salmon. He was treated with three courses of VAD therapy. Then he received high dose melphalan (200 mg/m2), followed by the ASCT. After two months from ASCT, he had bilateral blurry vision, pain, redness in both eyes and diplopia. We detected 5 mm of right-sided proptosis by Hertel exophthalmometry (base 110, 20 mm right eye, 15 mm left eye). Ocular motility of oculus dexter (OD) was restricted in up and lateral gaze. He has diplopia in up gaze. His color vision was 7 of 12 in the right eye and 10 of 12 in the left eye with Ishihara plates. Best corrected visual acuity was 6/10 in the right eye and 7/10 in the left eye. Intraocular pressures were 19 mmHg for OD and 18 mmHg for oculus sinister (OS). Slit lamp biomicroscopy revealed subconjunctival hemorrhages superiorly and temporally in the right eye and bilateral conjunctival hyperemia with chemosis. Fundus examinations of both eyes were unremarkable. Computed tomography and magnetic resonance imaging of orbita revealed a right intraorbital extraconal soft tissue density mass that involved the lacrimal gland and lateral rectus muscle. Prednisolon 1mg/kg/day and bortezomib 1.3 mg/m2 were started (1, 4, 8, 11 days). Eye findings were recovered after one month. Ocular relapse should be considered if there are ocular findings after ASCT for MM. Bortezomib and steroid may be useful for ocular extramedullary relapse of MM (Fig. 2, Ref. 8).
