Ophthalmic manifestations of multiple myeloma

Rare presentation of orbital metastasis in multiple myeloma

Orbital manifestations are rarely observed in multiple myeloma (MM) and when they occur, they are often the first manifestation. We report a rare occurrence of vision loss in a 51-year-old female from orbital metastases in MM without proptosis or diplopia. The ophthalmic presentation of MM is usually progressive proptosis, pain, diplopia, and visual loss. The presence of metastasis in MM indicates poor prognosis and orbital metastases have worse survival rates. In conclusion, in cases of profound vision loss with no obvious cause, neuroimaging should be performed to evaluate the orbital extent of the disease and exclude intracranial pathology.

Ocular complications of plasma cell dyscrasias

Plasma cell dyscrasias are a wide range of severe monoclonal gammopathies caused by pre-malignant or malignant plasma cells that over-secrete an abnormal monoclonal antibody. These disorders are associated with various systemic findings, including ophthalmological disorders. A search of PubMed, EMBASE, Scopus and Cochrane databases was performed in March 2021 to examine evidence pertaining to ocular complications in patients diagnosed with plasma cell dyscrasias. This review outlines the ocular complications associated with smoldering multiple myeloma and monoclonal gammopathy of undetermined significance, plasmacytomas, multiple myeloma, Waldenström's macroglobulinemia, systemic amyloidosis, Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy and Skin changes (POEMS) syndrome, and cryoglobulinemia. Although, the pathological mechanisms are not completely elucidated yet, wide-ranging ocular presentations have been identified over the years, evolving both the anterior and posterior segments of the eye. Moreover, the presenting symptoms also help in early diagnosis in asymptomatic patients. Therefore, it is imperative for the treating ophthalmologist and oncologist to maintain a high clinical suspicion for identifying the ophthalmological signs and diagnosing the underlying disease, preventing its progression through efficacious treatment strategies.

Orbital Involvement in Multiple Myeloma

PURPOSE

To characterize clinical and radiographic features, management, and outcomes of patients with orbital involvement of multiple myeloma (MM).

METHODS

A retrospective chart review identified patients with MM and orbital involvement confirmed by histopathology at a single institution between 1995 and 2021. A comprehensive literature review was performed via PubMed to identify all previously reported cases of orbital MM.

RESULTS

Retrospective review identified 7 patients (43% male, mean age 68.7 years). Presenting symptoms included proptosis and diplopia. Orbital lesions were primarily located laterally (42.8%) with associated extraocular muscle (57.1%) or lacrimal gland (42.9%) involvement. Five patients (71.4%) had a previous diagnosis of systemic MM. Six patients received chemoradiation (85.7%). All patients had improvement of orbital disease with 2 patients deceased due to disease at follow-up (mean 8.9 months). Literature review identified 111 cases (46.8% male, mean age 58.6 years). 48.6% presented with orbital disease as the first manifestation of systemic MM. Lesions were most commonly located superolaterally (20.2%) with extraocular muscle infiltration (25.2%), lacrimal gland involvement (7.2%), and orbital bony destruction (39.6%). Treatments included chemoradiation, chemotherapy, or radiation alone. Approximately half (51.4%) of patients experienced improvement in orbital disease following treatment, and 48.6% were deceased at follow-up (mean 20.1 months).

CONCLUSIONS

This study provides a new retrospective study and updated comprehensive literature review regarding orbital MM. Given its poor prognosis, characterization of orbital MM is essential for early diagnosis. Orbital MM is often unilateral, located superolaterally, and may represent the first manifestation of systemic disease. Treatment includes chemotherapy and radiation, which may improve orbital disease; however, the overall prognosis remains poor.

Case Report: Cavernous Sinus Syndrome as the Initial Presentation of Multiple Myeloma

Multiple myeloma (MM) is the second most common hematologic malignancy and most common primary bone malignancy. Ocular manifestations of MM are extremely rare and may be the first presentation leading to diagnosis. Ophthalmologists routinely encounter cavernous sinus syndrome, and there is a wide range of possible etiologies. Here, we present a case of a patient presenting with diplopia, ptosis, and ophthalmoplegia found to have a cavernous sinus plasmacytoma with systemic workup consistent with MM. MM is a rare cause of cavernous sinus syndrome and should be considered in the setting of a skull base mass.

Hidden in the Eyes—Recurrence of Systemic Hemopathies Reportedly “In Remission”: Six Cases and Review of Literature

Background and Objectives: Secondary ocular localizations of hematological malignancies are blinding conditions with a poor prognosis, and often result in a delay in the diagnosis. Materials and Methods: We describe a series of rare cases of ocular involvement in six patients with hematological malignancies, reportedly in remission, who presented secondary ocular localizations, challenging to diagnose. Two patients had an acute lymphoblastic leukemia (ALL) and developed either a posterior scleritis or a pseudo-panuveitis with ciliary process infiltration. One patient had iris plasmacytoma and developed an anterior uveitis as a secondary presentation. Two patients had a current systemic diffuse large B-cell lymphoma (DLBCL) and were referred either for intermediate uveitis or for papilledema and vitritis with secondary retinitis. Finally, one patient with an acute myeloid leukemia (AML) presented a conjunctival localization of a myeloid sarcoma. We herein summarize the current knowledge of ophthalmologic manifestations of extramedullary hematopathies. Results: Inflammatory signs were associated with symptomatic infiltrative lesions well displayed in either the iris, the retina, the choroid, or the cavernous sinus, from the admission of the patients in the ophthalmological department. These findings suggest that patients with ALL, AML, systemic DLBCL, and myeloma can present with ophthalmic involvement, even after having been reported as in remission following an effective systemic treatment and/or allograft. Conclusions: Early detection of hidden recurrence in the eyes may permit effective treatment. Furthermore, oncologists and ophthalmologists should be aware of those rare ocular malignant locations when monitoring patient’s progression after initial treatment, and close ophthalmologic examinations should be recommended when detecting patient’s ocular symptoms after treatment.

Relapsing Extramedullary Multiple Myeloma Presenting As Acute Liver Failure

Extramedullary spread of multiple myeloma was thought to be uncommon but with recent advancements in imaging and increased patient survival, the incidence of the extraosseous disease has risen in living individuals. Despite this, the extraosseous spread of multiple myeloma has been under-diagnosed and under-reported. Timely diagnosis of this extraosseous disease is clinically important, as it indicates a more aggressive disease variant and carries a poor prognosis.

Retinopathy secondary to multiple myeloma treated with bevacizumab

The case is presented on an 80-year-old woman with IgA multiple myeloma (MM), who developed retinal changes similar to mild non-proliferative diabetic retinopathy, with micro-aneurysms and intraretinal fluid. The patient was treated with systemic chemotherapy for MM, and with bevacizumab intravitreal injections, with control of her ocular disorder for 22 months. Anti-angiogenic therapy can be useful in the control of retinopathy secondary to MM, as long as the systemic disease has been controlled.

Bilateral Proptosis in a Case of Recurring Multiple Myeloma: Uncommon Orbital Presentation of Plasmacytoma

Multiple myeloma is a malignant plasma cell dyscrasia that may invade the orbits in extramedullary presentations. Common manifestations of orbital involvement include unilateral proptosis, injection, chemosis, diplopia, and occasionally pain. Additionally, the soft-tissue tumors associated with multiple myeloma typically cause bony destruction of adjacent structures. However, in certain patients, bilateral proptosis and a lack of bony destruction may occur. In these instances, it is important for physicians to consider patient history, presentation, and progression in order to ensure that a potentially fatal diagnosis is not missed. The reason this case is important is two-fold: 1) we describe a case of an individual with relapsing multiple myeloma presenting as bilateral proptosis and lacking bony destruction, highlighting the importance of understanding the disease process and 2) we discuss why patients with multiple myeloma may be more prone to developing tumors of the orbit in recurrent cases.

Multiple myeloma manifesting as an ocular salmon patch - a case report

Multiple myeloma (MM) is the second most prevalent hematologic malignancy after non-Hodgkin lymphoma and is currently considered incurable. Clinical ophthalmic manifestations of MM are rare but at the same time diverse. Ocular surface manifestations of multiple myeloma are uncommon. Conjunctival 'salmon patch' is a typical ocular surface ophthalmological sign with a distinct set of differential diagnoses, including most often ocular adnexal lymphoma. This case report presents a 33-year-old female with a relapse of MM manifesting as a conjunctival 'salmon patch'. The patient initially responded well to medical management including high dose melphalan supported by a third autologous stem cell transplantation (ASCT) and did not require further surgical excision of the ocular lesion. It is suggested that MM should be included in the differential diagnosis of 'salmon patch' conjunctival lesions.

Five cases of orbital extramedullary plasmacytoma: diagnosis and management of an aggressive malignancy

Purpose: Multiple myeloma is an insidious haematological malignancy characterised by monoclonal proliferation of plasma cells in the bone marrow. Extramedullary plasmacytoma is a rare manifestation of multiple myeloma and usually occurs in the upper respiratory tract. Orbital involvement is particularly uncommon, but may be associated with devastating visual impairment and poor clinical outcomes. Therefore, this article aims to highlight the need for multidisciplinary management of orbital extramedullary plasmacytoma. Methods: This is a retrospective observational case series of five patients. All presented to the authors for management of orbital extramedullary plasmacytomas from 2004 to 2015 at Prince of Wales and Mater Hospitals in Sydney, Australia. Medical records were reviewed for pertinent information including demographics, disease features, management strategy, and clinical progress. The study met Medical Ethics Board standards and is in accordance with the Helsinki Agreements. Results: This case series of five patients underscores the poor prognosis of orbital extramedullary plasmacytoma. Despite aggressive multidisciplinary management, four of these five patients succumbed to their illness during the study period. However, multidisciplinary management did manage to minimise symptoms and preserve quality of life. Conclusions: On a case-by-case basis, patients may derive palliative benefit from orbital surgery in conjunction with radiotherapy and chemotherapy. Orbital surgeons are encouraged to work within a multidisciplinary framework of medical specialists, including haematologists and radiation oncologists, when determining the optimal management plan in cases of orbital extramedullary plasmacytoma.

Right orbital edema masquerading a hematologic malignancy

Introduction:

Multiple myeloma is caused by abnormal proliferation of plasma cells that affects more commonly African Americans. It classically presents with hypercalcemia, renal failure, anemia, and lytic bone lesions. The aim of this article is to present an unusual case of a 63-year-old African-American female with multiple myeloma who presented with worsening right-sided eye swelling for the past 3 weeks and to briefly review ophthalmologic manifestations of multiple myeloma.

Case description:

Our patient’s presentation was associated with a throbbing frontal headache, nasal congestion, malaise, and weight loss. Differential diagnosis on admission included giant cell arteritis, conjunctivitis, preseptal cellulitis, glaucoma, acute sinusitis, or cavernous sinus thrombosis. Extensive ophthalmologic evaluation did not show any intraocular abnormality. However, a magnetic resonance imaging of the brain showed hyperintense foci in the right frontal calvarium leading to the eye swelling. Further evaluation revealed pancytopenia, elevated protein levels, and inverse albumin–globulin ratio suggestive of a plasma cell dyscrasia. A skeletal survey revealed multiple osteolytic lesions. Serum and urine protein electrophoresis revealed elevated immunoglobulin G Kappa monoclonal gammopathy. Bone marrow biopsy demonstrated a hypercellular marrow comprised at least 70% mature appearing plasma cells staining positive for CD138. Chemotherapy with cyclophosphamide, bortezomib, and dexamethasone was initiated. After 2 months of chemotherapy, orbital swelling has resolved with decrease in M-spike, immunoglobulin G, and serum kappa light chains.

Conclusion:

This case illustrates an unusual presentation of multiple myeloma which was eye swelling caused by bony infiltration in the calvarium. Although hematologic malignancies tend to have more specific signs and symptoms, they should be included in the differentials of unilateral orbital edema.

Ophthalmic Manifestations of Hematopoietic Malignancy

Purpose. To report the ocular findings in patients with hematopoietic malignancy with optic nerve involvement and abducens nerve palsy. Methods. The medical records of all cases of hematopoietic cancer with ophthalmic involvements seen in the Department of Ophthalmology of the National Center for Global Health and Medicine between 2009 and 2014 were reviewed. Results. Eight patients with hematopoietic cancer with optic nerve invasion or abducens nerve palsy were studied. The primary diseases were 3 cases of multiple myeloma, 1 case of acute lymphocytic leukemia, 1 case of follicular lymphoma, and 3 cases of AIDS-related lymphoma. Six cases had optic nerve invasion, 2 cases had abducens nerve palsy, and 1 case had optic nerve invasion of both eyes. The median visual acuity of eyes with optic nerve invasion was 0.885 logarithm of the minimum angle of resolution (logMAR) units. The final visual acuity of eyes with optic nerve invasion was 1.25 logMAR units, and that of those with sixth-nerve palsy was −0.1 logMAR units. Six cases died during the five-year follow-up period. An ophthalmic involvement in patients with hematopoietic cancer, especially AIDS-related lymphoma, was associated with poor prognosis. Conclusion. Because ophthalmic involvement in patients with hematopoietic malignancy has a poor prognosis, an early diagnosis of the cancers by the ophthalmologic findings by ophthalmologists could improve the prognosis.

How we diagnose and treat vitreoretinal lymphoma

The eye is a rare site for the development of malignant lymphoma. Based on cell type and involved intraocular structures, which as a whole represent an immune-privileged site, several subtypes of primary intraocular lymphoma need to be discerned. Primary vitreoretinal lymphoma (PVRL), the most common form, is an aggressive B-cell malignancy and considered a subtype of primary central nervous system (CNS) lymphoma. Ocular symptoms are non-specific and often mimic uveitis, frequently resulting in delayed diagnosis. Bilateral ocular involvement and dissemination/relapse in the CNS are common. Diagnosis of PVRL is usually based on the analysis of vitreous biopsy material. In addition to cytological and immunocytochemical examination, measurements of cytokine levels and molecular determination of B-cell clonality and recurrent mutations increase the diagnostic yield. Both systemic chemotherapy and exclusively local treatment, including ocular radiotherapy and intravitreal chemotherapy, are successful approaches for the management of PVRL, although it is currently not predictable which patients require systemic treatment in order to avoid cerebral dissemination, a complication associated with a considerably worse prognosis.

A rare entity in multiple myeloma: six nerve paralysis

Ophthalmic involvement appears rarely in multiple myeloma (MM). Ophthalmic findings are mostly noted as complications caused by disease or treatment. MM-associated with 6th nerve paralysis is a rare entity. Bortezomib, one of the novel agents used to treat MM, has neurotoxic effect and may cause permanent nerve damage. Herein, we report a 50-year-old male patient with MM who developed the 6th nerve paralysis while receiving bortezomib and discuss its relevant causes.

Optic nerve and dura mater involvement as the first sign of multiple myeloma

PURPOSE

To report a case of optic nerve and dura mater involvement as the first sign of multiple myeloma.

METHODS

Case report.

RESULTS

A 43-year-old woman presented with a headache and decreased vision in both eyes. Ophthalmic examination revealed anterior uveitis and subretinal mass around the optic nerves with accompanying disc edema bilaterally. Magnetic resonance imaging showed dural and optic nerve infiltration with tram-track enhancement in the optic nerve sheath. The diagnosis of multiple myeloma was made as a result of systemic investigations. The patient underwent systemic chemotherapy and cranial radiotherapy. After treatment, the patient's headache disappeared, the papilledema regressed, and the ocular findings improved but complete recovery could not be achieved because of fibrous subretinal tissue and degenerative changes of the optic nerve.

CONCLUSIONS

Neurologic and ophthalmic involvement in multiple myeloma may appear as the first manifestation of disease. The correct diagnosis is important because it can be life-saving.

Efficacy of lenalidomide in association with cyclophosphamide and dexamethasone in multiple myeloma patient with bilateral retro-orbital localisation

Extramedullary localisation is an uncommon manifestation in multiple myeloma (MM). Ocular involvement is rare. Here, we describe a relapse of MM with bilateral retro-orbital localisation without any bone involvement with good and rapid response to therapy with lenalidomide, dexamethasone, and cyclophosphamide.

Intraocular collision tumour: case report and literature review

BACKGROUND

"Collision" tumours consist of different neoplasms coexisting within a single lesion. Whilst quite common in the skin, the gastrointestional tract, and the ovaries, intraocular collision tumours are exceedingly rare. We describe an exceptional case of a combined uveal melanoma and intraocular plasmacytoma.

METHODS

Observational case report. A 61-year-old woman underwent enucleation for rubeotic glaucoma and cells in the anterior chamber after proton-beam radiotherapy of a cilio-choroidal melanoma of the right eye. Examination of the enucleated eye was performed with immunohistochemistry, multiplex ligation dependent probe amplification (MLPA), and polymerase chain reaction (PCR) for immunoglobulin heavy- and light-chain gene rearrangements. A review of the literature on ocular collision tumours and uveal involvement by plasma cell neoplasms was also performed.

RESULTS

Morphological, immunophenotypical, and genotypical examination of the tumour revealed the co-existence of both a melanoma and a plasmacytoma within the choroid and ciliary body. The glaucoma was caused by extensive infiltration of the iris and trabecular meshwork by the plasmacytoma cells. Review of the literature revealed only four collision tumours involving the eyelid and three involving the choroid. All three intraocular collision tumours consisted of uveal melanoma and choroidal non-Hodgkin lymphoma. Uveal involvement by plasma cell neoplasms is also extremely rare, with only six reported cases.

CONCLUSIONS

This is the first documented intraocular collision tumour consisting of a uveal melanoma and isolated plasmacytoma. If a patient presents with 'uveitis' after proton-beam radiotherapy of a cilio-choroidal melanoma, there may be scope for performing biopsies to determine whether the lymphoid infiltrate is reactive or neoplastic.

Multiple myeloma of the orbit

The authors report a case of a 62-year-old female with history of multiple myeloma who presents with complains of swelling and pain in her right eye. On examination, it was found that she has proptosis, chemosis, and diplopia along with decreased vision. Initial workup and treatment did not yield significant results, eventually she was found to have myelomatous changes in her right orbit on MRI and was diagnosed with multiple myeloma of the orbit which resolved solely with radiation. This case tends to highlight the importance of considering myeloma of the orbit as a very important and early differential diagnosis in a patient with a history of multiple myeloma presenting with a swollen and painful eye.

Acute optic neuropathy associated with an intracranial mass in a patient with POEMS syndrome

A 43-year-old man with POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes), including long-standing optic disc swelling, had sudden painless vision loss in the left eye. Brain MRI revealed an intracranial mass adjacent to the left optic nerve and enhancement of the optic nerve. The mass decreased in size following chemotherapy for myeloma with some recovery of vision. This represents a unique case of optic neuropathy due to presumed plasmacytoma in osteosclerotic IgA myeloma and POEMS syndrome.

Frontal skull craniotomy combined with moderate-dose radiotherapy effectively ameliorate a rare case of non-secretory, multiple myeloma with orbital involvement

BACKGROUND

Orbital infiltration in patients with multiple myeloma is a rare condition, with less than 50 cases reported in the medical literature. Most patients undergo conservative treatment because multiple myeloma is a disseminated systemic disease.

CASE PRESENTATION

A 43-year-old male subject with multiple myeloma and long-term survival presented with orbital involvement. The subject lacked the typical features and poor prognostic factors associated with multiple myeloma, such as renal failure, hypercalcemia, and paraprotein in the serum and urine. The orbital computed tomographic scan revealed the tumor encasing the optic nerve, but without prominent bony destruction. Therefore, a frontal skull craniotomy with an epidural entrance to the orbital space was performed, to completely extirpate the orbital mass. The surgical procedure was followed by moderate-dose radiation therapy. After 32 months of follow-up care, the subject is doing well with excellent local control.

CONCLUSION

Although the effectiveness and applicability of this approach remains to be determined, this case report demonstrates that accurate and early detection combined with local surgical treatment and appropriate radio/chemotherapy, can be applied to effectively extend an orbital multiple myeloma patient's life.

Multiple myeloma manifesting as a fluctuating sixth nerve palsy

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.

Characteristics of orbital multiple myeloma: a case report and literature review

Multiple myeloma is a plasma cell malignancy that destroys skeletal, renal, and neurological function. Orbital involvement is rare, but has been considered an initial presentation for the malignancy. Furthermore, an association between the subtype of multiple myeloma and the likelihood of orbital infiltration has been suggested. We present a case of an orbital mass that was a recurrence of multiple myeloma. A literature search was performed to evaluate the presentation characteristics of orbital multiple myeloma, plasmacytoma and primary (or solitary) extramedullary plasmacytoma. Past reports were analyzed for age, sex, symptoms at presentation, time from symptom onset to presentation, prior diagnosis before presentation for orbital symptoms, radiological characteristics, immunoglobulin subtype, and survival times. Less than half of published cases had orbital multiple myeloma as the primary presentation. Proptosis is the major presenting sign of orbital multiple myeloma, and radiological evaluation shows that the majority of masses originate in the superotemporal quadrant. The dominant immunoglobulin subtype was IgG.

Recurrence of Isolated Multiple Myeloma in the Skull Base: A Case Report and Review of the Literature

Extramedullary plasmacytoma involving the skull base is rare. We describe what we believe is the first reported case of recurrent multiple myeloma presenting as an isolated lesion in the central skull base in a patient with no evidence of systemic involvement. We discuss the patient's presentation, clinical course, and treatment, and we review the relevant scientific literature.

Bilateral Optic Neuropathy Associated with Multiple Myeloma

A 51-year-old man had reduced vision and bilateral optic disc swelling as the initial clinical manifestation of multiple myeloma. Brain imaging failed to disclose any abnormalities. Before any therapy was begun, visual function began to improve substantially. Three months after chemotherapy was started, visual function and optic disc appearance returned to near normal. There were no features to suggest polyneuropathy-organomegaly-endocrinopathy-M protein-skin changes (POEMS) syndrome. Visual loss in myeloma is usually caused by compression or infiltration of the optic nerves by tumor. The mechanism of the optic neuropathy in this case remains unknown.
