Purpose: The purpose of this article is to describe a case of Toxoplasma gondii chorioretinal granuloma mimicking a choroidal metastasis from colorectal adenocarcinoma. Methods: Evaluation included clinical examination with multimodal imaging techniques and chorioretinal biopsy. Results: A 37-year-old white male with a history of colorectal adenocarcinoma presented with painless vision loss in the right eye, and fundoscopic examination revealed an amelanotic choroidal lesion. Patient history, examination, and diagnostic imaging suggested an old choroidal metastatic lesion with the patient electing chorioretinal biopsy. Upon cytologic examination, the biopsy sample indicated absence of malignant cells or tissues; however, the sample demonstrated fibroglial tissue with associated inflammation and toxoplasma organisms. Conclusion: This case demonstrates an atypical presentation of toxoplasma chorioretinitis that can mimic the appearance of a metastasis. Immunocompromised patients may be particularly susceptible to this atypical presentation of chorioretinitis.

Melanoma of the eye is rare, but can mimic a range of disorders. This report highlights 2 cases of choroidal melanoma with vision loss mimicking neurological diagnoses. The first patient is a 41-year-old white male with a known history of multiple sclerosis and a previous episode of optic neuritis in the right eye, who presented with a 6-month history of decreased vision in the same eye, and occasional photopsiae. He was treated with 2 courses of oral steroids for presumed recurrent optic neuritis. After a temporary improvement in his symptoms, his vision worsened, following which he had a head MRI, which revealed a solid intraocular mass. He was subsequently diagnosed with a choroidal melanoma for which he was treated successfully with ruthenium-106 plaque brachytherapy. The second patient is a 57-year-old female, who presented with a progressive cerebellar syndrome under investigation by the neurology service, as well as decreased vision in the right eye. Her visual acuity gradually deteriorated and her neurological assessment, which included a PET-CT, revealed uptake in the right eye. The diagnosis of a choroidal melanoma was made, and following conservative treatment with proton beam radiotherapy, she had an enucleation of the eye. Intraocular tumours can masquerade as many different entities. Unexplained unilateral visual loss, especially if it is atypical for a neurological syndrome, should prompt dilated fundoscopy and referral to an ophthalmologist.

Abstract Background Non-arteritic ischaemic optic neuropathy (NAION) is a rare but harmful complication of prone positioning. Prone mechanical ventilation is a therapeutic strategy which has been used extensively during the COVID-19 pandemic to treat acutely hypoxemic patients with COVID-19 related acute respiratory distress syndrome (ARDS). Though a small number of cases of unilateral NAION have been reported in patients testing positive for the SARS-CoV-2 virus, we describe what is to our knowledge, the first reported case of bilateral NAION occurring in a patient proned extensively for the treatment of COVID-19 related ARDS. We consider the potential aetiological factors leading to NAION after prone mechanical ventilation in patients with COVID-19 and suggest strategies to protect against its development. Case presentation : We report a case of severe, irreversible, visual impairment secondary to bilateral anterior ION in a fifty-five-year-old male who underwent eight episodes of prone mechanical ventilation to treat COVID-19 related ARDS. Once weaned from his sedation he reported bilateral painless vision loss, and bedside ophthalmological assessment identified a reduced visual acuity of 3/30 unaided in the left eye and counting fingers in the right. Dilated indirect ophthalmoscopy revealed inferotemporal optic disc oedema with splinter haemorrhages in the right eye and mild disc oedema, temporal pallor, and nerve fibre layer haemorrhages inferiorly in the left eye. Humphrey visual field 24 − 2 testing confirmed a severely constricted visual field with macular sparing on the right and depressed inferonasal vision with preserved peripheral vision on the left eye. OCT disc imaging shortly after diagnosis revealed bilateral disc swelling and flame haemorrhages in the right eye. Conclusions NAION is a devastating, but preventable complication of prone positioning, which may pose significant risk of vision loss in patients with COVID-19 related ARDS.

Abstract Background Clinical guidelines do not recommend further investigation for occult malignancy in the scenario of unprovoked venous thromboembolism in the absence of additional clinical features suggestive of malignancy. We present the case of a young gentleman with pulmonary embolism who was diagnosed with testicular seminoma despite lack of symptoms or signs suggestive of malignancy. This is a unique case describing a scenario not well documented in existing literature where contravention of clinical guidelines had a potentially advantageous outcome for the patient. Case presentation A 37-year-old white male presented with seemingly unprovoked acute pulmonary embolism with right heart strain. He did not have any predisposing factors for venous thromboembolism and did not have any symptoms or signs suggestive of malignancy. Clinical guidelines do not recommend further investigation to screen for malignancy in this scenario. Despite this, our young, otherwise healthy patient proceeded to computed tomography scanning, resulting in the diagnosis of localized testicular seminoma. Testicular ultrasound described normal-sized testes (despite a discrete lesion in the right testis), suggesting this was not detectable by the patient or clinician on routine examination. The patient was anticoagulated and had an inferior vena cava filter inserted to facilitate orchidectomy followed by adjuvant radiotherapy. Conclusions This case highlights the importance of considering malignancy in seemingly unprovoked venous thromboembolism and the availability of guidelines to direct further investigation. Our patient’s treatment was not in line with clinical guidelines and was considered a “lucky find.”

AbstractAnterior clinoidal meningiomas (ACMs) remain a major neurosurgical challenge. The skull base techniques, including extradural clinoidectomy and optic unroofing performed at the early stage of surgery, provide advantages for improving the extent of resection, and thereby enhancing overall outcome, and particularly visual function. Additionally, when the anterior clinoidal meningiomas encase neurovascular structures, particularly the supraclinoid internal carotid artery and its branches, this further increases morbidity and decreases the extent of resection. Although it might be possible to remove the tumor from the artery wall despite complete encasement or narrowing, the decision of whether the tumor can be safely separated from the arterial wall ultimately must be made intraoperatively.The patient is a 75-year-old woman with right-sided progressive vision loss. In the neurological examination, she only had light perception in the right eye without any visual acuity or peripheral loss in the left eye. MRI showed a homogeneously enhancing right-sided anterior clinoidal mass with encasing and narrowing of the supraclinoid internal carotid artery (ICA). Computed tomography (CT) angiography showed a mild narrowing of the right supraclinoid ICA with associated a 360-degree encasement. The decision was made to proceed using a pterional approach with extradural anterior clinoidectomy and optic unroofing. The surgery and postoperative course were uneventful. MRI confirmed gross total resection (Figs. 1 and 2). The histopathology was a meningothelial meningioma, World Health Organization (WHO) grade I. The patient continues to do well without any recurrence and has shown improved vision at 15-month follow-up.This video demonstrates important steps of the microsurgical skull base techniques for resection of these challenging tumors.The link to the video can be found at https://youtu.be/vt3o1c2o8Z0

A 36-year-old patient presented to the hospital with recurrent dislocation of the intraocular lens (IOL). The patient with the diagnosis of familial ectopia lentis was first operated on for crystalline lens subluxation in the left eye in 2007 and in the right eye in 2009. In both eyes, lens extraction with anterior vitrectomy and transscleral fixation of a rigid IOL was performed. In 2011, the IOL in the right eye luxated into the vitreous cavity due to ocular trauma. The patient underwent a pars plana vitrectomy with the IOL resuturation to the sclera. Seven years later, a spontaneous vision loss in the right eye was caused by a retinal detachment. The pars plana vitrectomy with silicone oil tamponade and a consequential oil removal three months later were performed in 2018. The follow-up examination revealed recurrent IOL dislocation in the same eye. Due to a history of previous suture-related complications a decision was made to remove the subluxated rigid polymethyl-methacrylate (PMMA) IOL and fixate to sclera a sutureless SOLEKO FIL SSF Carlevale lens. The purpose of this report is to present a single case of a 36-year-old patient who was presented to the hospital with recurrent dislocation of the intraocular lens. In a three-month follow-up period, a good anatomical and functional outcome was finally obtained with transscleral sutureless intraocular lens. This lens is an option worth considering especially in a young patient with a long life expectancy and physically active.

A 33 years’ old male complained of excessive salivation with frequent swallowing and spitting, which resulted in communication disturbance, reduced quality of life, and social embarrassment for 19 years. He had been diagnosed as sialorrhea and submandibular gland hyperfunction by stomatologist, then had unilateral submandibular gland resection 13 years ago, but the symptom relief was not satisfactory. After that, he had been treated with glycopyrrolate for less than a year, which was withdrawn because of the short duration of symptomatic control after each tablet take-in and intolerable side effects. With the wish to receive a new treatment with long term effectiveness, low re-operation risk and normal preserved saliva secretion function, the patient was subject to MWA for the right submandibular gland. After systematic clinical evaluation, US-guided percutaneous MWA was successfully performed with an uneventful post-operative course. The volume of the right submandibular gland and ablated area were measured precisely by an ablation planning software system with automatic volume measurement function based on three-dimensional reconstruction of the pre-operative and post-operative enhanced magnetic resonance imaging (MRI) raw data. Finally, the ablated volume was calculated as 62.2% of the whole right submandibular gland. The patient was discharged 1 day after the operation, with symptoms relieved significantly, the mean value of whole saliva flow rate (SFR) decreased from 11 ml to 7.5 ml per 15 minutes. During the follow up by phone three months after operation, the patient reported that the treatment effect was satisfactory, whereas the SFR value became stable as 7 ml per 15 minutes, drooling frequency and drooling severity (DFDS) score decreased from 6 to 5, drooling impact scale (DIS) score decreased from 43 to 26. US-guided percutaneous MWA of submandibular gland seems to be an alternative, minimal invasive, and effective treatment for refractory sialorrhea. We described a patient with refractory sialorrhea treated successfully with ultrasound (US) guided percutaneous microwave ablation (MWA).

Abstract Introduction: Choroidal metastases are the most frequent intraocular secondary tumours, with a prevalence of 2–7% according to the literature. Our aim was to review a clinical case of choroidal metastasis. We present a case of a 63-year-old male patient diagnosed in 2018 with lung adenocarcinoma cT4N0M1. The patient had three metastases in the brain, which were successfully treated with radiosurgery (RS). The patient was treated with chemotherapy with pemetrexed–cisplatin schedule. Five months after diagnosis, the patient presented with decreased vision in the right eye. After ophthalmologic evaluation, he was diagnosed with a right choroidal metastasis, which was treated with external beam radiotherapy with 20 Gy in five fractions, resulting in improved visual acuity and a complete clinical and radiological response. The patient took part in a clinical trial that continued with systemic chemotherapy. Twenty-two months after radiotherapy to the eye, the patient has good visual acuity without any side effects. Conclusions: Choroidal metastasis treated with radiotherapy achieves good local control, with limited side effects, allowing an improvement in visual acuity and consequently, an improvement in the patient´s quality of life.

Metastatic tumours of the hand are uncommon. The majority of these tumours affect the phalanges and the primary tumours are usually bronchogenic in origin, with breast and kidney tumours next in frequency. Metastatic gastrointestinal to the hand is rare and usually from the colon. We report a case of poorly differentiated adenocarcinoma of the stomach antrum presenting with a metastatic lesion to the right 4th metacarpal bone. A review of the literature is included.

A 54-year-old healthy male presented complaining of sudden loss of vision in the right eye. Initial visual acuity was counting fingers. The patient’s acute vision loss developed after sexual activity. Color fundus photos and fluorescein angiography were performed showing a large subinternal limiting membrane hemorrhage in the macular area. A 23-gauge sutureless pars plana vitrectomy with brilliant blue assisted internal limiting membrane peeling was performed with best-corrected visual acuity recovery to 20/50 at 6 months of followup.
