Adenoid cystic carcinoma is an uncommon epithelial cell tumour that usually originates from glands. They arise from the upper respiratory tract, lungs, mammary glands, and skin, but most commonly from the salivary glands and lacrimal glands. Our article reports a 53-year-old individual presenting with a history of diminution of visual acuity over the past one and a half months, also associated with a right-sided headache and throbbing eye pain not relieved by medication. Examination revealed right axial proptosis, ptosis, and visual acuity of 6/36, right afferent pupillary defect (RAPD), restriction of ocular movements in supraduction, dextroelevation, and abduction. The fellow eye was completely normal. MRI revealed an enhancing lesion in the retrobulbar area of the right orbit indicative of optic nerve glioma of stage 2. The patient underwent orbito-zygomatic craniotomy with subtotal excision of the mass by a neurosurgeon. Following surgery, histopathological examination of the excised tumour revealed features consistent with adenoid cystic carcinoma. On the third post-operative day, the subject's vision improved to counting fingers at 3 metres, and extraocular movements were regained.
腺样囊性癌是一种罕见的上皮细胞肿瘤，通常起源于腺体。它起源于上呼吸道、肺、乳腺和皮肤，但最常见于唾液腺和泪腺。我们的文章报道了一名53岁的患者，在过去一个半月中有视力下降的病史，同时伴有右侧头痛和搏动性眼痛，药物治疗无效。检查发现右眼轴向突出、上睑下垂，视力为6/36，右侧传入性瞳孔障碍（RAPD），上转、右旋和外展时眼球运动受限。对侧眼完全正常。磁共振成像（MRI）显示右眼眶球后区域有一个强化病变，提示为2期视神经胶质瘤。该患者接受了神经外科医生进行的眶颧开颅手术及肿物次全切除术。术后，对切除肿瘤的组织病理学检查显示其特征与腺样囊性癌一致。术后第三天，患者视力改善至能在3米处数指，眼球运动也恢复了。
