However, the etiology of CEAN remains unclear, and no association with infection, trauma, or immunosuppression has been described.This case study indicated that CEAN is closely related to the patient’s impaired immune status and may be induced by cyclosporine.CASE SUMMARY A 19-year-old boy with nephrotic syndrome(NS) developed large CEAN on the left foot during treatment for NS. He had repeated relapses of edema in the past 6 years and different types of immunosuppressants were administered including methylprednisolone, mycophenolate mofetil, tacrolimus and cyclosporine;the dosages of these drugs were frequently adjusted. The patient had been receiving cyclosporine and methylprednisolone for 7 mo before he developed CEAN.Cyclosporine was discontinued due to its side effects on skin. After cessation of cyclosporine and 16 mo follow-up, the nodules gradually disappeared without any other treatment for the CEAN.CONCLUSION Impaired immune status is proposed to be a risk factor for CEAN, which may be induced by cyclosporine.展开更多

Type 1 is the benign variant, in which meningothelial is the most common subtype. Angiomatous also belongs to the same subtype but comprises only 2.1% of all meningiomas. Although most meningiomas are asymptomatic, some may present with varying symptoms ranging from seizures to focal deficits. Often, large meningiomas can also manifest as neuropsychiatric symptoms ranging from depression to overt psychosis. Here, in this case, we have further elaborated the importance of the organic cause of psychiatric symptoms as our patient initially presented with symptoms of depression. Regarding the diagnosis of meningiomas, nowadays excellent neuro-imaging methods are available, however, histological examination and immunohistochemistry remain the gold standard tools for a definite diagnosis. In our patient, the histological examination showed well-formed sinusoids and vascular channels which were consistent with the diagnosis of an angiomatous variant. Gross total resection of the lesion remains the treatment of choice with radiation therapy being used for residual tumors postoperatively. Being a type 1 variant, these meningiomas have a very small risk of recurrence. Here, we have presented a rare variant of meningioma initially presenting with prominent psychiatric symptoms of depression advancing to focal deficits.展开更多

All eyes were treated with anti-VEGF therapy. Abrupt visual loss was defined as loss of 5 or more lines in best-corrected visual acuity(BCVA) in comparison to the previous visit. The incidence and timing of abrupt visual loss as well as the factors associated with it, were determined. In addition, the BCVA at the final follow-up was compared between the eyes with and those without abrupt visual loss.RESULTS: The mean follow-up period was 42.4±18.9 mo after diagnosis, and abrupt visual loss was noted in 22 eyes(16.1%) at a mean of 19.6±13.9 mo. Abrupt visual loss was found to be associated with subretinal hemorrhage in 11 eyes(50.0%), development of or increase in the height of pigment epithelial detachment with fluid in 8 eyes(36.4%), and tears in the retinal pigment epithelium in 3 eyes(13.6%). The logarithm of minimum angle of resolution(logMAR) mean BCVA at the final follow-up was 2.07±0.67(Snellen equivalents: 20/2349) and 1.00±0.55(20/200) in eyes with and without abrupt visual loss, respectively. BCVA was significantly worse in the eyes with abrupt visual loss(P<0.001).CONCLUSION: Abrupt visual loss is noted in 16.1% of patients with type 3 neovascularization and is associated with poor visual outcome. Additional studies are needed to determine how abrupt visual loss can be prevented.展开更多
