Dermoid cysts are common periorbital lesions. They usually occur near the superolateral orbital rim, indenting but not extending within the bony outer table. We present an unusual case of a dumbbell-shaped dermoid cyst underlying the temporalis muscle with extension into the lateral wing of the greater sphenoid bone, approaching the optic canal. The cyst was successfully removed en bloc via a small skull base craniectomy without spillage of cyst contents. The patient recovered well without neurological or visual sequelae.
皮样囊肿是常见的眶周病变。它们通常发生在眶上外侧缘附近，压迫但不延伸至骨外板内。我们报告一例罕见的哑铃形皮样囊肿病例，该囊肿位于颞肌下方并延伸至大翼蝶骨外侧翼，靠近视神经管。通过小型颅底颅骨切除术成功将囊肿完整切除，囊肿内容物未溢出。患者恢复良好，无神经或视觉后遗症。
