Wegener’s Granulomatosis of the Orbit: A Review of Clinical Features and Updates in Diagnosis and Treatment

Management of Orbital Granulomatous Polyangiitis Presenting with Lacrimal Gland Involvement: Treatment of Subsequent Peripheral Ulcerative Keratitis, Anterior Uveitis, and Exudative Retinal Detachment in a Challenging Case

This case report discusses a case of granulomatosis with polyangiitis (GPA) initially presenting with lacrimal gland involvement and subsequently developing additional features. GPA is a disease known for inflammation in the respiratory tract and kidneys. A 63-year-old male patient presented with a mass, swelling, and ptosis in the right upper eyelid. The patient was referred to us when his symptoms had persisted and worsened despite topical and oral antibiotic therapy administered at another center. Based on clinical and laboratory findings from evaluation and consultations, GPA was diagnosed and confirmed by biopsy. The patient initially presented with necrotizing scleritis and later developed peripheral ulcerative keratitis and anterior uveitis, which regressed under cyclophosphamide treatment but progressed to exudative retinal detachment due to orbital involvement. Clinical remission was achieved after adding rituximab therapy. Presentation with lacrimal gland involvement may serve as an initial manifestation of locally aggressive orbital and adnexal GPA, which can exhibit variable clinical features. Rapid diagnosis and aggressive treatment are critical for preserving vision and preventing complications in patients with GPA.

An Evidence-Based Approach to Diagnosing Patients Presenting With Orbital Inflammatory Syndromes (An American Ophthalmological Society Thesis)

PURPOSE

The initial management of patients presenting with orbital inflammatory syndromes varies-with some pursuing a diagnostic workup while others treat without any testing. The evidence behind this rationale is limited. A review of patients with orbital inflammation is performed with an analysis of diagnostic testing to develop a workflow for such patients.

DESIGN

A retrospective review of patients presenting with acute orbital inflammation at a single institution from 2011 to 2020 was conducted.

METHODS

Orbital imaging was required for inclusion. Patients with high suspicion of neoplasm, bacterial infection, vascular malformation, or thyroid eye disease were excluded. A review of presenting clinical findings, laboratory workup, orbital imaging, and biopsy were performed. Statistical analysis was performed identifying statistically significant diagnostic and treatment maneuvers.

RESULTS

In total, 172 patients met inclusion criteria (66% female, mean age 46 years). The primary clinical presentation was myositis, dacryoadenitis, and infiltrative in 67, 73, and 32 patients (39.0%, 43.0%, 18.6%, respectively). Laboratory studies were conducted in 145 (84%) while biopsy was performed in 55 (32%). Specific orbital inflammation (SOI) was diagnosed in 29 (16.9%) with the most frequent diagnoses being sarcoidosis, IgG4-related disease, inflammatory bowel disease, and systemic lupus erythematosus. The majority (147, 85.5%) was initially treated with steroids, but steroid-sparing agent use was statistically higher in patients with SOI.

CONCLUSIONS

In patients presenting with orbital inflammatory syndromes, distinguishing myositis, dacryoadenitis, and infiltrative disease has workup and differential diagnosis impacts. Because SOI is relatively common, sequelae of SOI, and potential steroid-sparing therapy needs, diagnosis via an evidence-based systemic approach is critical.

Non-infectious Dacryoadenitis

Dacryoadenitis is an inflammation of the lacrimal gland that may have various etiologies with similar presentations. Despite more recent elucidation of specific causes, the management has remained largely unchanged. Hence, the condition remains under biopsied with the rationale that empirical treatment with corticosteroids is effective for many of the causes. Dacryoadenitis, however, dacryoadenitis can be the presenting sign of an undiagnosed systemic disease and a mimick for lymphoma; hence, tissue diagnosis and systemic investigations play a vital role. A significant proportion of dacryoadenitis has a specific etiology, and IgG4-related dacryoadenitis is more frequently identified as a cause. We summarize the different types of immune-mediated dacryoadenitis, their clinical findings, histopathology, management, and prognosis. We have also highlighted and formulated practice guidelines for diagnosis and effective treatment based on the underlying systemic disease.

Radiotherapy of granulomatosis with polyangiitis occurring in the eyelid: A case report and literature review

INTRODUCTION

Granulomatosis with polyangiitis (GPA) is a chronic systemic vasculitis characterized by necrotizing granulomatous vasculitis. The disease mainly affects the middle and small blood vessels and mainly occurs in the upper respiratory tract (nose and paranasal sinuses), lower respiratory tract (lungs), and kidneys. Disease occurrence in the eyelid area is relatively rare. The standard GPA treatment is combination therapy with adrenocortical hormone and immunosuppressants. Radiotherapy as a treatment option for GPA has not been widely investigated.

PATIENT CONCERNS

A 29-year-old man presented with a 1.0 × 1.0 cm mass without exophthalmos and decreased vision in the left lower eyelid. Computed tomography revealed a mass-like high-density shadow below the left eye with a computed tomography value of 80-108 U.

DIAGNOSIS

The laboratory investigations revealed positive cytoplasmic antineutrophil cytoplasmic antibodies (titer = 1:40). Biopsy of the lower left eyelid mass revealed necrosis and granulomatous reaction with a large number of inflammatory cell infiltration. After consultation with the pathology department, the diagnosis was determined as left lower eyelid GPA.

INTERVENTIONS

The patient received 9MeV electron beam radiation therapy in the area of the left lower eyelid lesion.

OUTCOMES

The lesion in the patient was significantly reduced and the symptom relieved obviously. No symptom recurrence or significant toxicity occurred during or after the treatment. The patient remains under routine follow-up.

CONCLUSION

We present a case of a male patient with GPA located exclusively in the eyelid area, who underwent successful radiotherapy and achieved a complete response. The lesson we learned from this case study is that for GPA patients, when the standard treatment model fails to achieve good results, novel treatments such as radiotherapy should be considered according to the situation.

Orbital manifestations of granulomatosis with polyangiitis: 12-year experience in Mexico City

PURPOSE

To present the clinical picture and radiological characteristics of orbital manifestations of granulomatosis with polyangiitis in a Mexican hospital and compare them with worldwide literature.

METHODS

Retrospective, observational study from January 2007 to January 2019. An electronic file review was performed. All patients with the diagnosis of granulomatosis with polyangiitis (GPA) in the Oculoplastics department were included. Ophthalmological examination, biopsy, antibodies and tomographical results were included in the data collected. Descriptive statistics were obtained.

RESULTS

One hundred and one patients in our institute had a diagnosis of GPA. Only 15 (14.8%) had orbital manifestations and were included in our study. 73.3% were female with a median age of 46.20 years (17-81). Diagnostic delay was on average 6 months. Only 6.7% had bilateral manifestations. No past medical history was found in 40%, 20% had a previous diagnosis of systemic GPA. Pain was reported in 73.3%. Increase of volume (proptosis or diffuse orbital mass) was present in 86.7%. C-ANCA antibodies were positive in seven patients (46.7%). In tomography, lacrimal gland involvement was present in 33.3% and diffuse orbital mass was present in 66.6%. Definite diagnosis was done with biopsy in 93.3%. One patient died from complications of GPA.

CONCLUSIONS

Ophthalmologists should consider this rare disease as a differential diagnosis of orbital tumors, as it may have different clinical manifestations, even in non-Caucasian population. When in doubt, biopsy is always valuable. The statistics at our reference center correspond with statistics reported worldwide.

Rare Presentation of Severely Limited Granulomatosis With Polyangiitis Manifesting With Orbital Wall Destruction: Literature Review and Case Report

Necrosis resulting from mechanical local factors can be seen in patients with granulomatosis with polyangiitis (GPA) even in remission. GPA can cause serious morbidity even when limited. An ocular prosthesis that increases inflammation and damages local circulation should be used very carefully in such patients. In this article, we report a 68-year-old male patient who was diagnosed with localized GPA 11 years ago and referred to our clinic with the complaint of displacement of an ocular prosthesis inside the nose and epistaxis. Four years ago, the left eye was enucleated because of pain and vision loss. Two months after the enucleation, the patient began to use an ocular prosthesis. Orbital medial wall destruction developed while the patient was receiving maintenance therapy that consisted of cyclophosphamide (150 mg/day) plus prednisolone (32 mg). When the ocular prosthesis was displaced in the nasal cavity, the prosthesis was first removed and the patient was clinically stabilized. Later, orbital wall reconstruction was performed at another center.

Imaging of orbital disorders

Diseases of the orbit can be categorized in many ways, but in this chapter we shall group them according to etiology. Inflammatory diseases of the orbits may be infectious or noninfectious. Of the infections, orbital cellulitis is the most common and typically arises as a complication of acute sinusitis. Of the noninfectious, inflammatory conditions, thyroid orbitopathy is the most common and results in enlargement of the extraocular muscles and proliferation of the orbital fat. Idiopathic orbital inflammatory syndrome is another cause of inflammation in the orbit, which may mimic thyroid orbitopathy or even neoplasm, but typically presents with pain. Masses in the orbit may be benign or malignant and the differential diagnosis primarily depends on the location of the mass lesion, and on the age of the patient. Lacrimal gland tumors may be lymphomas or epithelial lesions of salivary origin. Extraocular muscle tumors may represent lymphoma or metastases. Tumors of the intraconal fat are often benign, typically hemangiomas or schwannomas. Finally, globe tumors may be retinoblastomas (in children), or choroidal melanomas or metastases in adults.

Granulomatosis with polyangiitis (Wegener's disease): An updated review of ocular disease manifestations

Granulomatosis with polyangiitis (GPA) is a potentially lethal systemic disorder that is characterized by necrotizing vasculitis of small arteries and veins. The respiratory system is most commonly affected in limited forms of the disease, however upper and lower respiratory system, systemic vasculitis, and necrotizing glomerulonephritis are the characteristic components of the disease triad. The peak incidence is observed at 64-75 years of age, with a prevalence of 8-10 per million depending on geographic location. In this review we focus on the ocular manifestations of the disease which occur in nearly in one third of the patients. In addition we describe the neuro-ophthalmic complications which occur in up to half of cases. We also discuss the current systemic treatment options including corticosteroids, cyclophosphamide, azathioprine, and the available biologic response modifiers including rituximab. The disease remains difficult to diagnose due to the generalized symptomatic presentation of patients with GPA. As a result, several sets of diagnostic criteria have been developed which include clinical, serological, and histopathological findings to varying extents. Early diagnosis and multi-specialty collaboration among physicians is necessary to adequately manage the disease and the potential complications that may result from drugs used in the treatment of the disease. Despite recent advances, more research is necessary to prevent the high rates of mortality from the disease itself and from therapeutic side effects.

Investigation of Anti-Myeloperoxidase Antibodies in a Dog with Bilateral Necrotizing Scleritis

Necrotizing scleritis is uncommon in dogs and presumed to be immune-mediated. Its clinical pattern and histopathology are similar to ocular lesions observed in humans suffering from granulomatosis with polyangiitis (GPA), formerly named Wegener’s granulomatosis, where the pathogenesis revolves around anti-neutrophil antibodies (e.g., anti-myeloperoxidase). These antibodies are used to diagnose and follow-up the disease in humans, but variants that only affect the eyes often test negative. Here, we present the first case of canine necrotizing scleritis where measurement of anti-myeloperoxidase antibodies was attempted. A 1.5 year-old female Scottish Terrier was presented with bilateral deep multifocal scleromalacia, severe inflammation of corneal/uveal/retrobulbar tissues, perilimbal corneal oedema and neovascularization, hypotony, and mild exophthalmos. Corticosteroids and antibiotics had been administrated (topically and orally) without success. Due to painful multifocal scleral perforation with vitreal haemorrhage, the left eye underwent enucleation, so did the right eye one week later. The histopathology of the left eye revealed a neutrophilic and histiocytic scleral infiltration with extension of pyogranulomatous inflammation to the cornea, choroid, ciliary body, and orbital fat. Levels of plasma anti-myeloperoxidase antibodies were not statistically significant to those of 13 healthy dogs. Further research is warranted to investigate the presence and role of anti-neutrophil antibodies in canine necrotizing scleritis.

Orbital granulomatosis with polyangiitis (Wegener granulomatosis): clinical and pathologic findings

The pathology of granulomatosis with polyangiitis (GPA), formerly Wegener granulomatosis, typically features a granulomatous and sometimes necrotizing vasculitis targeting the respiratory tract and kidneys. However, orbital involvement occurs in up to 60% of patients and is frequently the first or only clinical presentation in patients with systemic or limited forms of GPA. Orbital GPA can cause significant morbidity and potentially lead to complete loss of vision and permanent facial deformity. Fortunately, GPA is highly responsive to medical treatment with corticosteroids combined with cyclophosphamide or, more recently, rituximab. Therefore, it is imperative for this disease to be accurately diagnosed on orbital biopsy and distinguished from other histologically similar orbital lesions. Herein, we review the clinical and pathologic findings of orbital GPA, focusing on the differentiation of this disease from other inflammatory orbital lesions.

Limited Wegener's Granulomatosis Presenting with an Isolated Abduction Deficit

Wegener's granulomatosis often affects the orbit, typically presenting with painful proptosis. The authors describe a 14 year-old girl, with limited Wegener's granulomatosis, who initially presented with an isolated painless abduction deficit that spontaneously resolved over several weeks. She subsequently developed painful proptosis and diplopia, followed by facial and oral nodules. This case demonstrates that limited Wegener's granulomatosis can rarely present with an isolated painless abduction deficit.

[Wegener's granulomatosis]

Wegener's granulomatosis is a necrotizing inflammation of small and medium size vessels with granuloma formation. It is a very heterogeneous disease in respect of severity and clinical manifestation. While it can be a rapidly progressive disease with fatal ending, there are forms limited only to one organ. Diagnosis is supported by the positivity of anti-neutrophil cytoplasmatic antibody and the presence of the typical histological findings. Unfortunately, these examinations cannot confirm clinical suspicion relatively frequently. In addition, there may be only symptoms related to one single organ for a long time at the beginning of the disease and, therefore, one have to be aware of the clinical signs and symptoms of the different organ systems. This may allow us to make an early diagnosis and start treatment in time.

Granulomatosis with polyangiitis: the relationship between ocular and nasal disease

PURPOSE

To analyze the relationship between ocular manifestations and nasal pathology.

METHODS

A retrospective study of 19 granulomatosis with polyangiitis (GPA) patients with ophthalmic and nasal manifestations.

RESULTS

Ten cases exhibited changes in orbital structure accompanied by changes in paranasal sinuses, 2 cases had chronic dacryocystisis, and 1 case had nasolacrimal canal stenosis. Among the 17 cases that were finally diagnosed by biopsy, 12 cases were diagnosed by nasal mucosa biopsy. Sixteen GPA cases were diagnosed by CT or MRI. Nasal involvement alone or with orbital involvement was detected in 14 cases. All cases were misdiagnosed for 2-36 months.

CONCLUSIONS

Granulomatosis with polyangiitis with ocular and upper respiratory diseases as the first symptom is easily misdiagnosed. Patients with ocular and upper respiratory diseases should be given a laboratory ANCA test, nasal mucosa biopsy, and imaging of the orbit, nasal cavity, and paranasal sinuses to establish early diagnosis of GPA.
