Two children (aged 18 and 23 months at the initial examinations) were each ultimately found at surgery to have a solitary eosinophilic granuloma of the lateral orbital wall. Both patients had a symptomatic period of six weeks during which time other diagnoses were considered: bacterial preseptal cellulitis and mumps dacryoadenitis in the first case and traumatic recurrent orbital hematoma in the second. Diagnostic difficulties stemmed from confusing features in their histories, as well as the location of the lesion and the deceptively minimal swelling relative to the actual size of the lesion. Follow-up ten and 18 months after curettage of the two lesions showed no recurrence or evidence of systemic involvement. Although most reported cases describe the orbital frontal bone as the site of origin in the orbit, our cases demonstrated that unifocal eosinophilic granuloma may occur in the lateral wall of the orbit.
两名儿童（初诊时年龄分别为18个月和23个月）最终均在手术中被发现患有外侧眶壁孤立性嗜酸性肉芽肿。两名患者均有为期六周的症状期，在此期间考虑了其他诊断：第一例为细菌性睑前蜂窝织炎和流行性腮腺炎泪腺炎，第二例为外伤性复发性眶内血肿。诊断困难源于病史中的混淆特征，以及病变的位置和相对于病变实际大小而言看似轻微的肿胀。对这两个病变进行刮除术后10个月和18个月的随访显示无复发或全身受累迹象。尽管大多数报道的病例将眶额骨描述为眼眶的起源部位，但我们的病例表明单灶性嗜酸性肉芽肿可能发生在眶外侧壁。
