Mycotic ocular infections caused by the Scedosporium apiospermum species complex are challenging to treat because of the delayed diagnoses and poor responses to antifungal drugs and surgical treatment.
A case of a 69-year-old male patient with a history of diabetes mellitus type 2 and prior surgery on the right femur is described. In the 10 days prior to the ophthalmic consultation he started with ocular pain, adding to a previous and progressive loss of visual acuity in his right eye. The diagnosis of endophthalmitis of probable endogenous origin was established. Despite medical treatment, the patient's condition worsened and, due to the imminent risks, an enucleation was performed. Smears of the enucleation tissue revealed fungal cells, and the cultures yielded a fungus belonging to the S. apiospermum species complex, which was identified as Scedosporium boydii by morphological characteristics and sequencing of a PCR amplicon.
A diagnosis of endophthalmitis of probable endogenous origin in the right eye was based on a previous right femur surgery. Potential risk to the patient led to enucleation.
由阿氏丝孢霉复合种引起的真菌性眼部感染由于诊断延迟以及对抗真菌药物和手术治疗反应不佳而难以治疗。
描述了一例69岁男性患者,有2型糖尿病病史且右股骨曾接受过手术。在眼科会诊前10天,他开始出现眼痛,右眼之前已有视力逐渐下降的情况。确诊为可能为内源性的眼内炎。尽管进行了药物治疗,患者病情仍恶化,由于存在紧迫风险,遂行眼球摘除术。眼球摘除组织涂片显示有真菌细胞,培养物培养出一种属于阿氏丝孢霉复合种的真菌,通过形态学特征和PCR扩增子测序鉴定为博伊德丝孢霉。
基于之前的右股骨手术,诊断右眼可能为内源性眼内炎。患者面临的潜在风险导致了眼球摘除术。
