We report a case of presumed cryptococcal endophthalmitis that occurred in a patient with severe disseminated cryptococcosis and AIDS. Multiple small, spherical lesions appeared bilaterally on the surface of the retina 2 weeks after cryptococcal meningitis was diagnosed; the lesions were associated with multiple blind spots, blurred vision, and the perception of flaring of light. Over the next week, many more lesions with adjacent hemorrhages appeared. Therapy with itraconazole over the next 3 months resulted in complete resolution of the lesions. Cryptococcal endophthalmitis is a rare disease. Fewer than 20 cases, including five in patients with AIDS, have previously been reported. None of these patients regained normal vision.

Endogenous Candida endophthalmitis (ECE) is a rare disease. We present a patient with Candida endophthalmitis after two consecutive procedures of suction dilatation and curettage for elective abortion. A 24-year-old single woman who received a suction dilatation and curettage one week ago developed pain and blurred vision in the right eye. Endogenous Candida endophthalmitis was diagnosed and treated with oral fluconazole and pars plana vitrectomy with adjunction of intravitreal amphotericin B injection. The vitreous culture revealed Candida albicans. The vitreous inflammation subsided greatly after the initial treatment but flared up after the second dilatation and curettage for incomplete abortion 5 days after the vitrectomy. The oral fluconazole was replaced by intravenous amphotericin B, and a second vitrectomy with injection of intravitreal amphotericin B was performed. Postoperatively, the intraocular inflammation resolved gradually. Six months after the second vitrectomy, the best-corrected visual acuity in the right eye was 20/25. The excellent visual acuity of this patient was attributed to the early diagnosis and aggressive treatment. For patients with mild disease, less toxic oral fluconazole as the systemic antifungal agent instead of more toxic intravenous amphotericin B has been recommended. For those with advanced disease, intravitreal amphotericin B in conjunction with vitrectomy has been advocated by many eye surgeons.

Superficial siderosis of the central nervous system is a very rare disease related to hemosiderin deposits in the brain, brainstem, cerebellum and spinal cord due to chronic subarachnoid hemorrhage. Chronic increased intracranial pressure develops in about one-third of affected cases. We report a patient with superficial siderosis and sudden intracranial pressure crisis. A 29-year-old man experienced a subacute episode of headache, tinnitus and blurred vision. Magnetic resonance imaging of the brain revealed hemosiderin deposits characteristic of superficial siderosis. Extensive diagnostic work-up excluded causative pathologies of bleeding. Lumbar puncture and continuous intra-ventricular cerebrospinal fluid (CSF) pressure monitoring revealed continuous CSF pressure increase. Implantation of a ventriculo-peritoneal shunt led to complete clinical recovery. Our case emphasizes that patients with superficial siderosis may present with sudden elevation of intracranial pressure due to chronic intracranial hypertension. In this situation permanent CSF drainage provides a useful therapeutic option.

Acute tubulointerstitial nephritis and bilateral uveitis (TINU) syndrome is a rare disease usually occurring in young women. We report the exceptional case of a 48-year-old man with TINU syndrome who had a 10-month history of interstitial nephritis before the onset of uveitis. Findings from the renal biopsy specimen indicated tubular atrophy, dense infiltration of lymphocytes, granulomatous infiltration with multinucleated giant cells, and disruption of the vessel wall. The patient was initially diagnosed to have chronic kidney disease; interstitial nephritis could not be diagnosed until blurred vision occurred. However, he was successfully treated with steroid pulse and oral maintenance therapy. Steroid therapy may be effective to treat TINU syndrome irrespective of the onset of the disease.

To describe the clinical features of a patient with toxoplasmic pachymeningitis and provide a review of the recent cases of pachymeningitis in the literature.Retrospective, observational case report. A one-eyed patient who presented to our institution with blurred vision, floaters, and visual field shrinkage. Review of clinical, laboratory, perimetric, and radiologic records of the patient and description of the efficacy of antibiotic therapy. The signs of ocular impairment, including visual acuity, visual field, and magnetic resonance imaging (MRI) changes. A one-eyed patient who complained of blurred vision and unexplained visual field shrinkage was evaluated. The diagnosis of toxoplasmic pachymeningitis was confirmed by existence of a toxoplasmic seroconversion, cerebrospinal fluid abnormalities, radiological features, absence of other diagnoses, improvement of symptoms, and resolution of pachymeningitis in MRI with oral trimethoprim-sulfamethoxazole combination.Pachymeningitis is a rare disease and toxoplasmic pachymeningitis has never been described. Among the various infectious causes, screening for toxoplasmosis must be performed because it can lead to pachymeningitis and sequelae. Variable features may lead to misdiagnosis and delay in the treatment of this sight-threatening and potentially fatal disease.

Aspergillosis in the central nervous system (CNS) is a very rare disease in immune-competent patients. There was a case of a healthy man without a history of immune-compromised disease who had invasive aspergillosis with unusual radiologic findings. A 48-year-old healthy man with diabetes mellitus, presented with complaints of blurred vision that persisted for one month. Brain magnetic resonance imaging (MRI) showed multiple nodular enhancing lesions on the right cerebral hemisphere. The diffusion image appeared in a high-signal intensity in these areas. Cerebrospinal fluid examination did not show any infection signs. An open biopsy was done and intraoperative findings showed grayish inflammatory and necrotic tissue without a definitive mass lesion. The pathologic result was a brain abscess caused by fungal infection, morphologically aspergillus. Antifungal agents (Amphotericin B, Ambisome and Voriconazole) were used for treatment for 3 months. The visual symptoms improved. There was no recurrence or abscess pocket, but the remaining focal enhanced lesions were visible in the right temporal and occipital area at a one year follow-up MRI. This immune-competent patient showed multiple enhancing CNS aspergillosis in the cerebral hemisphere, which had a good outcome with antifungal agents.

Pulmonary large-cell neuroendocrine carcinoma (LCNEC) is a rare and malignant form of lung cancer with a poor prognosis for patients. The common sites of metastases are the liver, adrenal glands, bone and brain. LCNEC rarely metastasizes to the small intestine, ovaries, tonsils, mandible, vulva or spine. To the best of our knowledge, there have been no reports of leptomeningeal metastasis of LCNEC to date. The present case report describes an unusual case of leptomeningeal metastasis from pulmonary LCNEC alongside a review of the literature. Biopsies of pulmonary lesions and cervical lymph nodes confirmed the diagnosis of LCNEC in a 39-year-old male patient. At 2 months after chemotherapy, the patient began to experience hoarseness, epileptic seizures and blurred vision. Furthermore, the patient presented with radiating pain and numbness in his lower left limb. Imaging findings and cytological examination of cerebral spinal fluid supported the diagnosis of leptomeningeal metastasis. The patient's neurological symptoms were markedly alleviated following receipt of radiation and intrathecal chemotherapy. The patient survived for 4.9 months after diagnosis with leptomeningeal metastasis. To the best of our knowledge, the present case report is the first to describe leptomeningeal metastasis from pulmonary LCNEC confirmed by neuroimaging and cerebral spinal fluid cytology. It suggests that leptomeningeal metastasis does occur in this rare disease, and aggressive treatment may result in improved symptoms and possibly survival times.

A 33-year-old man presented with a 10-day history of bilateral blurred vision on a background of a prodromal influenza-like illness. Ocular Coherence Tomography (OCT) and fundal examination coincided with a diagnosis of atypical central serous retinopathy. The patient's symptoms worsened during follow-up, and he was started on steroids. Subsequent fundal examination revealed yellow deposits in a honeycomb pattern and hard exudates in the perimacular region. Serial OCTs revealed progression of bilateral macular intraretinal and subretinal fluid. He was subsequently admitted to hospital for a full paraneoplastic workup. Liaison with our colleagues in other specialist retinal centres led us to a diagnosis of acute exudative polymorphous vitelliform maculopathy syndrome. We subsequently took fundal images to monitor disease progression and to monitor changes seen with autofluorescence in this rare disease entity.

Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare disease characterised by the association of acutetubulointerstitial nephritis and uveitis. It affects mainly children and young women. Drugs and infections may be precipitating factors. It is a diagnosis of exclusion. The mainstays of treatment are topical and systemic corticosteroids. Prognosis is usually favourable. We report a case of TINU which occurred in our unit. A 37-year-old woman presented with an influenza-like illness, bilateral ocular pain and blurred vision. Ophthalmological evaluation revealed bilateral anterior uveitis and later renal involvement was seen as acute tubulointerstitial nephritis. A diagnosis of TINU was assumed after exclusion of other systemic diseases. She was treated with topical corticosteroids for the uveitis and evolved favourably, with resolution of ocular symptoms and normalisation of serum creatinine and proteinuria. This case highlights the importance of a high degree of clinical suspicion to make the diagnosis of TINU syndrome.

Microsporidium keratoconjunctivitis is an very rare disease. It is related to outbreaks in Asia due to exposure to contaminated water or soil. Microsporidium keratoconjunctivitis is a a self-limited disease, but it could have long term courses. We present the case of a 29 year old woman who started with pain, redness and blurred vision after a holiday in Singapore and did not respond to conjunctivitis treatment. PCR sequencing and PAS staining of corneal epithelial biopsy identified Vittaforma corneae as the causative organism. Treatment was initiated with corneal debridement, oral albendazol, and intensive topical voriconazole, levofloxacin and propamidine, but the conjunctival and corneal disease was only resolved 5 months later with the introduction of topical steroids to treat her severe limbitis. Suspicion of Microsporidium keratoconjunctivitis should be raised amongst ophthalmologists in unilateral keratitis with mild conjunctivitis in travelers from Asia.
