Unilateral Periorbital Swelling in a Pediatric Patient.

Infratemporal fossa (ITF) tumors are rare in children and may present with a variety of symptoms. Teratomas are neoplasms derived from the 3 germ layers and approximately 6% to 10% are within the head and neck. Our study discusses one of the first reported cases of teratoma in the ITF in a pediatric patient. A 3-year-old girl presents with 2 years of recurrent monthly left periorbital swelling accompanied by fevers, skin discoloration, and pain. Prior episodes were treated with antibiotics with incomplete resolution. Imaging revealed a cystic lesion centered in the ITF. She was taken for endoscopic endonasal biopsy of the lesion and had no complications. Pathology revealed a mature teratoma composed primarily of pancreatic tissue. Providers should consider masses such as teratoma in the differential for ITF tumors and periorbital edema unresponsive to typical treatment.

Metastasis of small cell lung cancer to bilateral extraocular muscles: a case report.

BACKGROUND: Orbital metastasis is a possible complication of small cell lung cancer and a pattern of bilateral invasion of the extraocular muscles has rarely been reported in literature. CASE PRESENTATION: A 46-year-old white male with a past medical history of smoking and stage IV small cell lung carcinoma presented with loss of vision and pain in the left eye. Examination revealed bilateral proptosis and left afferent pupillary defect, and visual acuity was hand motion on the left eye and 4/10 on the right eye. An orbital computed tomography scan showed a compression of the left optic nerve between the extraocular muscles at the apex, and a lateral canthotomy was performed for a new-onset compressive optic neuropathy, with residual visual improvement. There was also significant enlargement of the extraocular muscles in the right orbit. The patient was maintained in palliative treatment with both chemotherapy and local medical and surgical (amniotic membrane cover for exposure keratopathy) ophthalmological treatments until he eventually died 5 months after. CONCLUSION: Bilateral metastasis to the extraocular muscles is a very rare manifestation of small cell lung cancer and the palliative treatment in these cases is challenging.

Predictive factors of the postoperative proptosis recovery in surgery of spheno-orbital meningiomas.

OBJECTIVE: This study aimed to identify factors affecting proptosis recovery in spheno-orbital meningioma (SOM) surgery and assess functional and oncological outcomes. METHODS: Data from 32 consecutive SOM surgery cases (2002-2021) were analyzed. Clinical, radiological, operative, and oncological parameters were examined. Proptosis was assessed using the exophthalmos index (EI) on MRI or CT scans. Statistical analyses were performed to identify predictive factors for proptosis recovery. RESULTS: Proptosis improved in 75% of patients post-surgery (EI decreased from 1.28 ± 0.16 to 1.20 ± 0.13, p = 0.048). Patients with stable or worsened EI had higher body mass index (28.5 ± 7.9 vs. 24.1 ± 4.7, p = 0.18), Simpson grade (IV 75% vs. 65%, p = 0.24), and middle sphenoid wing epicenter involvement (63% vs. 38%, p = 0.12), but no significant factors were associated with unfavorable exophthalmos outcomes. The improvement group had higher en plaque morphology, infratemporal fossa invasion, and radiation treatment for cavernous sinus residual tumor (88% vs. 75%, p = 0.25; 51% vs. 25%, p = 0.42; 41% vs. 25%, p = 0.42, respectively), but without statistical significance. Visual acuity remained stable in 78%, improved in 13%, and worsened in 9% during follow-up. Surgery had a positive impact on preoperative oculomotor nerve dysfunction in 3 of 4 patients (75%). Postoperative oculomotor nerve dysfunction was observed in 25%, of which 75% fully recovered. This occurrence was significantly associated with irradiation of an orbital tumor residue (p = 0.04). New postoperative trigeminal hypoesthesia was observed in 47%, of which 73% recovered. All SOMs were classified as WHO grade 1, and complementary treatments achieved oncological control, requiring gamma-knife radiosurgery in 53% and standard radiotherapy in 6%. CONCLUSIONS: Surgery effectively improves proptosis in SOM, though complete resolution is rare. The absence of predictive factors suggests multifactorial causes, including body mass index and tumor resection grade. Postoperative oculomotor nerve dysfunction and trigeminal hypoesthesia are common but often recover. Gamma-knife radiosurgery maintains long-term oncological control for evolving tumor residue.

Teprotumumab in thyroid eye disease.

Thyroid eye disease (TED) is an inflammatory condition involving the periocular and orbital soft tissues, affecting most commonly patients with hyperthyroid disorders. Traditional treatments used for the active phase of the disease range from conservative lubrication for mild symptoms to systemic immunomodulating drugs for moderate-to-severe symptoms. Teprotumumab (Tepezza) is a monoclonal antibody with an inhibitory effect on insulin-like growth factor 1 and is the first Food and Drug Administration (FDA) approved targeted medical therapy for reducing the inflammatory signs and symptoms associated with TED. Two large multicenter, randomized, double-masked, placebo-controlled trials have confirmed the efficacy and safety of teprotumumab in patients with active, moderate-to-severe TED. Recent reports and publications have also demonstrated the efficacy of teprotumumab in a wider range of patients. In this review, we summarize the clinical features and pathophysiology of TED, disease course, and traditional management methods. We further detail the development of teprotumumab, the founding studies that brought it to its FDA approval, adverse events profile, and ongoing as well as future investigations.

Dural sinus malformation presenting with proptosis: report and review of a rare entity.

Dural sinus malformation (DSM) is a rare vascular malformation characterized by the dilatation of a dural venous sinus with or without an anomalous jugular bulb. Its presentation with venous-reflux-related secondary proptosis is anecdotal, with only six such cases reported so far. We report a 17-month-old boy who presented with a progressive proptosis of the right eye secondary to a DSM of the transverse sinus and torcula. Following endovascular embolization of the arterio-venous fistula, complete thrombosis of the venous lake and improvement in proptosis was noted at 6-month follow-up. Prognosis of this rare malformation is variable and dependent on specific angio-architectural features.

Sarcoid-like reaction of the orbit in diffuse large B-cell lymphoma.

Sarcoid-like reaction (SLR) has been reported in patients with solid tumor malignancies, lymphomas, and patients receiving immunotherapy. SLR is often incidentally found during positron emission tomography/computed tomography scans as hilar and/or mediastinal lymphadenopathy. SLR has also been found in the lung, spleen, bone marrow, and skin. Biopsy of these lesions shows noncaseating granulomas. When systemic criteria are not met for sarcoidosis, these noncaseating granulomas are termed SLR. We present the first case in the literature of a case of orbital SLR in a patient with concomitant diffuse large B-cell lymphoma and inverted papilloma of the maxillary sinus. This case highlights the importance of including malignancy in the differential for the presence of a noncaseating granuloma in the orbit.

Change in upper eyelid position after teprotumumab treatment for thyroid eye disease.

PURPOSE: Despite the high prevalence, treatment challenges, and significant impact of eyelid retraction on vision and quality of life among patients with thyroid eye disease, the effects of teprotumumab on eyelid retraction are not fully understood. This study evaluated change in upper eyelid position after teprotumumab. METHODS: A retrospective study of all patients who completed eight teprotumumab infusions at one institution from January 1 2020 to December 31 2022. Primary outcome was change in upper eyelid position immediately after treatment and at most recent follow-up compared to pre-treatment. RESULTS: Among 234 eyes of 118 patients, average margin reflex distance-1 (MRD1) pre-treatment was 5.25 mm (range 0-10.0, SD 1.75), 4.66 mm (1.0-9.0, SD 1.32) immediately post-treatment (p < 0.001), and 4.50 mm (0-10.0, SD 1.52) at most recent follow-up (mean follow-up duration 10.60 months). In total, 136 (58.12%) eyes of 88 patients had MRD1 reduction immediately post-treatment, averaging 1.49 mm (0.5-5.0 mm, SD 0.97). Every 1-mm increase in pre-treatment MRD1 increased the odds of MRD1 reduction by 15.03% (CI 10.52-19.72, p < 0.001) and increased the reduction amount by 0.48 mm (CI 0.39-0.57, p < 0.001). Of 154 eyes of 78 patients with most recent follow-up, 107 (69.48%) eyes had stable or further improved retraction at most recent follow-up compared to immediately post-treatment. CONCLUSIONS: This study found a modest but significant reduction in MRD1 in approximately 60% of eyes, independent of proptosis change, which was sustained by most patients over longer-term follow-up. Higher pre-treatment MRD1 corresponded with greater improvement. These results suggest an overall mild benefit of teprotumumab for upper eyelid retraction.

One-step orbit reconstruction using PMMA implants following hyperostotic sphenoid wing meningioma removal: Evolution of the technique in short clinical series.

Purpose: To report our experience with patient specific implants for one-step orbit reconstruction following hyperostotic SWM removal and to describe the evolution of the technique through three surgical cases. Methods: Three cases of one-step SWM removal and orbit reconstruction are described. All cases are given consecutively to describe the evolution of the technique. Hyperostotic bone resection was facilitated by electromagnetic navigation and cutting guides (templates). Based on a 3D model, silicone molds were made using CAD/CAM. Then PMMA implant was fabricated from these molds. The implant was adjusted and fixed to the cranium with titanium screws after tumor removal. Results: Following steps of the procedure changed over these series: hyperostotic bone resection, implant thickness control, implant overlay features, anatomic adjustments, implant fixation. The proptosis resolved in all cases. In one patient the progressive visual acuity deterioration was recognized during the follow-up. No oculomotor disturbances and no tumor regrowth were found at the follow-up. Conclusion: CAD/CAM technologies enable creation of implants of any size and configuration, and thereby, to increase the extent of bony resection and lower the risk of tumor progression. The procedure is performed in one step which decreases the risk of postoperative morbidity.

Unilateral Proptosis and Bilateral Compressive Optic Neuropathy in a Meningioma Patient.

Unilateral proptosis can be a sign of a potential threat to vision or life. Here, we report a case of unilateral proptosis with bilateral asymmetrical compressive optic neuropathy. A 36-year-old Malaysian indigenous female presented with painless right-eye proptosis associated with progressive blurring of vision for the past month. She had painless progressive left-eye vision loss for eight years. There was marked right-eye proptosis with partial ophthalmoplegia. The optic nerve functions were significantly reduced in the left eye with a positive relative afferent pupillary defect (RAPD). Humphry perimetry showed a right superior nasal field defect. Brain imaging showed two different masses located at the suprasellar and right greater wing of the sphenoid extraaxial lesion likely representing a meningioma. She was diagnosed with bilateral compressive optic neuropathy secondary to intracranial mass and was referred to the neurosurgical team for further intervention. This case highlights that painless proptosis with early vision loss of the fellow eye may be the early presenting symptom of meningioma, without any symptoms of raised intracranial pressure. Brain imaging is warranted to rule out any intracranial pathology if a visual field defect is present.

The Mechanism of Polygonum Hydropiper L-Coptis Chinensis in the Treatment of Ulcerative Colitis Based on Network Pharmacology and Experimental Validation.

BACKGROUND: Polygonum hydropiper L (PH) was widely used to treat dysentery, gastroenteritis, diarrhea and other diseases. Coptis chinensis (CC) had the effects of clearing dampness-heat, purging fire, and detoxifying. Study confirmed that flavonoids in PH and alkaloids in CC alleviated inflammation to inhibit the development of intestinal inflammation. However, how PH-CC affects UC was unclear. Therefore, the aim of this study is to analyze the mechanism of PH-CC on ulcerative colitis (UC) through network pharmacology and in vivo experiments. METHODS: The active ingredients and targets of PH-CC and targets of UC were screened based on related databases. The core targets of PH-CC on UC was predicted by protein-protein interaction network (PPI), and then the Gene Ontology-biological processes (GO-BP) function enrichment analysis was conducted using the Database for Annotation, Visualization and Integrated Discovery (DAVID) database. The binding activity between pyroptosis proteins, core targets and effective ingredients were verified based on molecular docking technology. Finally, combined with the results of network pharmacology and literature research, the mechanism of PH-CC against UC was verified by in vivo experiments. RESULTS: There were 23 active components and 191 potential targets in PH-CC, 5275 targets in UC, and 141 co-targets. GO-BP functional analysis of 141 co-targets showed that the first 20 biological processes were closely related to inflammation and lipopolysaccharide (LPS) stimulation. Furthermore, core targets had good binding activity with the corresponding compounds. Animal experiment indicated that PH-CC effectively prevented weight loss in UC mice, reduced the disease activity index (DAI) score, maintained colon length, suppressed myeloperoxidase (MPO) activity, inhibited pyroptosis protein expression, and downregulated the levels of IL-18 and IL-1ß to alleviate intestinal inflammation. CONCLUSIONS: The results of network pharmacology and animal experiments showed that PH-CC suppressed the inflammatory response, restored colon morphology, and inhibited pyroptosis in UC mice. Thus, PH-CC may improve UC by regulating the NOD-like receptor protein domain 3 (NLRP3)/Caspase-1 signaling pathway.

Ossifying fibroma of the ethmoid and sphenoid sinuses: A report of a rare case and literature review.

Background: Fibro-osseous lesions include a variety of bone lesions with different clinical and histopathological features. Case Description: We report a case of cemento-ossifying lesion involving the left ethmoid and sphenoid sinus in a 17-year-old male patient. Computed tomography showed an expansile hyperdense lesion with sclerosed peripheral mantle epicentered on the left ethmoid and sphenoid sinus and extending into the left nasal cavity. Magnetic resonance imaging was done for preoperative planning. Transnasal endoscopic resection was performed and histopathological examination confirmed the diagnosis of ossifying fibroma (OF). Conclusion: Involvement of the ethmoid sinus with OF is a rare condition; therefore, we examined the literature for similar cases to highlight the possible clinical presentation and management. Endoscopic management is a safe, effective approach with a low rate of complications.

Hypoglossal Canal Dural Arteriovenous Fistula: A Rare Cause of Ocular Proptosis.

It is exceedingly rare for dural arteriovenous fistulae (DAVFs) outside of the cavernous sinus to present with ophthalmological symptoms and signs. Hypoglossal canal DAVFs (HC-DAVFs) have only previously been reported as individual cases or small case series. Further, only an estimated 31% of HC-DAVFs present with ophthalmological findings. We report a noteworthy case of an HC-DAVF in a 74-year-old male who presented with proptosis, chemosis, and reduced visual acuity. He was treated endovascularly with liquid embolic filling. This report aims to highlight HC-DAVF as an important differential diagnosis for patients presenting with symptoms suggestive of arterialisation of the ophthalmic veins.

Unilateral orbital schwannoma arising from the supraorbital nerve: Report of a rare case.

Schwannomas are rare tumors in the orbit, typically originating from various nerves and presenting diagnostic challenges. We present a unique case of a unilateral orbital schwannoma arising from the supraorbital nerve. A 55-year-old female presented with a painless, slowly growing mass in the right superior orbit, causing proptosis. Visual acuity remained unimpaired, and clinical examination revealed a well-defined mass in the superior orbit. A provisional diagnosis of an orbital dermoid or cyst was made, leading to excision biopsy. The histopathological examination confirmed a diagnosis of benign schwannoma. Schwannomas in the orbit, particularly those arising from the supraorbital nerve, are uncommon and often challenging to diagnose. Early surgical intervention is crucial to prevent complications associated with tumor growth. This case underscores the need to consider schwannomas as a differential diagnosis for slow-growing orbital masses in adults and emphasizes the importance of timely management to prevent vision-threatening complications.

A case of bilateral amyloidosis localized to extraocular muscles mimicking thyroid eye disease.

BACKGROUND: Amyloidosis is a rare condition characterized by the abnormal deposition of amyloid proteins in various tissues and organs. While systemic amyloidosis has been well-documented, amyloid deposition in extraocular muscles is an exceptionally rare occurrence, with only 35 reported cases. This case report sheds light on the importance of considering amyloidosis in the differential diagnosis of patients presenting with proptosis and diplopia, which are often associated with thyroid eye disease. CASE PRESENTATION: A woman in her twenties sought medical attention due to a complaint of diplopia. Her ocular examination revealed almost normal findings except for exotropia and proptosis. Orbital magnetic resonance imaging displayed fusiform enlargement of nearly all eye muscles, a presentation typically observed in thyroid eye disease. However, despite corticosteroid therapy, her symptoms showed no improvement. Given the unusual lack of response to conventional treatment, and inhomogeneous enhancement of the muscle, an extraocular muscle biopsy was conducted. This biopsy yielded a unique finding-amyloid deposition within the muscle tissue. This discovery was particularly intriguing due to the extreme rarity of amyloidosis affecting extraocular muscles, with fewer than three dozen documented cases worldwide. CONCLUSION: This unique case underscores the critical need for a comprehensive approach to diagnosing patients with proptosis and diplopia. While these symptoms are commonly attributed to thyroid eye disease, it is essential to consider alternative diagnoses such as amyloidosis, especially when standard treatments fail to yield results. The discovery of amyloid deposition in the extraocular muscles, although exceedingly rare, emphasizes the significance of a thorough differential diagnosis. In conclusion, this case report highlights the importance of vigilance in clinical practice, encouraging ophthalmologists to explore less common diagnostic possibilities when faced with challenging cases. Further research and clinical investigation are warranted to better understand the mechanisms and potential treatments for amyloidosis affecting the extraocular muscles.

Unusual presentation of aneurysmal bone cyst (ABC) in children: pediatric intracranial osteosarcoma with secondary ABC.

A 13-year-old female patient presented with painless vision loss and proptosis for 18 months. Imaging findings were highly suggestive of a supraorbital aneurysmal bone cyst (ABC) for which she underwent complete surgical excision. Postoperatively, she developed left hemiparesis. Computed tomography angiography (CTA) revealed right complete internal carotid arterial (ICA) thrombosis. This was managed conservatively, and she improved in hemiparesis over the next 3 weeks. Histopathology report revealed osteosarcoma with secondary ABC, for which she was referred for radiotherapy. At 1.5 months follow-up, the patient's left lower limb power improved to 4 + /5. She was walking without support, and her left upper limb power was 4/5.

A comparison of proptosis reduction with teprotumumab versus surgical decompression based on fat-to-muscle ratio in thyroid eye disease.

PURPOSE: To explore if orbital fat-to-muscle ratio (FMR) is predictive of whether surgical decompression or teprotumumab leads to greater proptosis reduction in thyroid eye disease (TED). METHODS: A single-center retrospective cohort study comparing surgical decompression with teprotumumab according to FMR. All TED patients completing an 8-dose course of teprotumumab between January 2020 and September 2022 and all patients undergoing bony orbital decompression from January 2017 to December 2019 were included. Subjects were excluded if they were <18 years, received both surgical decompression and teprotumumab, or lacked orbital imaging. The primary exposure variable was teprotumumab or surgical decompression. The secondary exposure variable was baseline FMR. The primary outcome measure was change in proptosis (mm). RESULTS: Thirty-eight patients, mean age 53.5 years (±11.4), were included in the teprotumumab group and 160 patients, mean age 48 years (±11.1), in the surgical group. Average proptosis reduction after teprotumumab and surgical decompression was 3 mm (±1.44) and 5 mm (±1.75), respectively. The FMR was stratified at the median of 1.80. In subjects with FMR < 1.80, teprotumumab showed equivalent proptosis reduction compared to surgical decompression, -0.33 mm (SE 1.32) p = .802. In subjects with FMR ≥ 1.80, surgical decompression led to significantly more proptosis reduction than teprotumumab, 3.01 mm (SE 0.54), p < .001. CONCLUSIONS: Baseline FMR can be used to counsel patients as to proptosis reduction with teprotumumab versus surgery. Subjects with low FMR obtain comparable proptosis reduction with teprotumumab or surgery, whereas high FMR is associated with more significant proptosis reduction following surgery over teprotumumab.

Liver Transplantation for Zellweger Syndrome.

Zellweger syndrome or cerebrohepatorenal syndrome is a rare, multisystem disorder occurring due to defect in metabolic pathway within the peroxisomes. Cirrhosis with portal hypertension is an important presentation of these patients. Given its progressive, multisystem nature, the role of liver transplantation (LT) in Zellweger syndrome remains undefined and controversial. An 11-y-old boy diagnosed with Zellweger syndrome presented to the authors with decompensated cirrhosis along with bilateral proptosis. After a meticulous evaluation, he was offered an ABO incompatible liver transplantation with his mother being the donor. He had an uneventful post operative period. After a follow up of 24 mo, he has normal graft function, normal cognition along with resolution of proptosis. Therefore, in a group of carefully selected patients with Zellweger syndrome, a liver transplantation can be offered successfully with an excellent prognosis.

Postoperative Closed-Suction Drain in Anterior Orbitotomy.

Purpose To evaluate the role of a closed-suction drain in orbital mass excision following anterior orbitotomy. Methods This is a prospective, randomized comparative study of consecutive patients undergoing anterior orbitotomy and mass excision enrolled into two groups: group A (with drain) and group B (without drain). Clinical data included visual acuity assessment, proptosis measured by exophthalmometry, pain score assessment, eyelid swelling, and ocular motility. Postoperative data were compared for one to five days and at 14 and 30-day follow-ups in the two groups to evaluate the efficacy of closed-suction drain in orbital mass excision. Results Twenty-five patients planned for anterior orbitotomy were divided into two groups: group A (drain, n = 12) and group B (without drain, n = 13). The subsidence of proptosis (p = 0.041), eyelid swelling (p = 0.04), and restoration of ocular motility (p = 0.04) were faster in the drain group as compared to the non-drain group, which was observed as statistically significant. The outcomes at 30 days were comparable in both groups and none of the patients developed any long-term complications. Conclusion The use of orbital drains aids early postoperative recovery with faster subsidence of proptosis and eyelid edema, and rapid recovery of ocular movements but does not affect the final outcome. Orbital surgeons can individualize the use of closed-suction drains after anterior orbitotomy in cases with expected postoperative edema.

Orbital cholesterol granuloma: Case report and literature review.

Cholesterol granuloma is a chronic foreign-body inflammatory response that is often seen in the middle ear, mastoid antrum, and petrous apex. However, it can also occur in other anatomical locations, including the orbit. A 34-year-old male presented with painless nonaxial proptosis of the left eye, and imaging revealed a well-defined intraorbital extraconal lesion consistent with an orbital cholesterol granuloma. The pathogenesis of this rare cystic condition is unknown, but trauma and inadequate airflow through pneumatized temporal bone air cells have been proposed as potential triggers. Treatment involves total excision of the granuloma with careful removal of residual tissue adherent to the bone and the periosteum to minimize the risk of recurrence. Cholesterol granulomas usually have a good prognosis.

Resumen Introducción: El pseudotumor inflamatorio ocular asociado a IgG4 es un proceso inflamatorio no neoplásico y poco frecuente con una incidencia de 0.28-1.08 por cada 100,000 personas. El diagnóstico de esta patología es de exclusión debiendo cumplir criterios histopatológicos, agrandamiento de un órgano en específico y concentraciones serias de IgG4. El tratamiento tiene como objetivo evitar las complicaciones secundarias. Caso clínico: Mujer de 54 años de edad sin patologías previas referidas, acude refiriendo que 6 meses previos presenta de forma súbita y sin causa aparente prurito a nivel de globo ocular y párpado izquierdo, además de disminución de la agudeza visual y dolor retroocular, motivo por el que acude a valoración. Al examen físico presentó movimientos oculares normales, proptosis izquierda, dolor a la palpación, hiperemia subconjuntival, opacidad corneal, ausencia de reflejo rojo y más renitente a la presión el ojo izquierdo en relación con el contralateral. Tomografía cráneo-toraco-abdominal reporta a nivel ocular izquierdo imágenes sugestivas de melanoma coroideo sin hallazgos de actividad metastásica. Se realiza enucleación de ojo izquierdo. Se envía pieza a patología la cual reporta infiltrado difuso linfoplasmocítico positivas para IgG4. Conclusión: La enfermedad por IgG4 ocular es una patología muy infrecuente de clínica inespecífica y diagnóstico complejo. Sin embargo, un abordaje rápido y correcto es fundamental para evitar complicaciones.

Abstract Introduction: IgG4-associated ocular inflammatory pseudotumor is a rare, non-neoplastic inflammatory process with an incidence of 0.28-1.08 per 100,000 people. The diagnosis of this pathology is one of exclusion, having to meet histopathological criteria, enlargement of a specific organ, and serious concentrations of IgG4. Treatment aims to avoid secondary complications. Clinical case: A 54-year-old woman with no previous reported pathologies, reports that for the past 6 months she has itching at the level of the eyeball and the left eyelid, suddenly and without apparent cause, in addition to decreased visual acuity and retro-ocular pain; this is why she asked for the evaluation. The physical examination revealed normal eye movements, left proptosis, pain on palpation, subconjunctival hyperemia, corneal opacity, absence of red reflex, and the left eye being more resistant to pressure in relation to the contralateral eye. The cranio-thoraco-abdominal tomography reported images at the left ocular level that were suggestive of choroidal melanoma without findings of metastatic activity. Enucleation of the left eye was performed. The specimen was sent to pathology which reported diffuse lymphoplasmacytic infiltrate positive for IgG4. Conclusion: Ocular IgG4 disease is a very rare pathology with non-specific symptoms and complex diagnosis. However, a quick and correct approach is essential to avoid complications.
