摘要 目的报道眶额区皮样囊肿和表皮样囊肿的CT征象。资料与方法回顾性分析经手术病理证实的眶额区皮样囊肿和表皮样囊肿各2例的CT表现。结果4例囊肿边界清晰,囊内密度不均,3例以脂性密度为主,其中2例表皮样囊肿局限性压迫额骨颧突,1例皮样囊肿以水样密度为主伴小斑片低密度影,沿颧额缝向外生长。结论眶额区皮样囊肿和表皮样囊肿具有特征性CT表现。 Objective To report CT features of congenital dermoid cyst and epidermoid cyst in the fronto-orbital region. Materials and Methods CT findings of 4 cases with pathologically proved congenital dermoid and epidermoid cyst of the fronto-orbital region were retrospectively analysed. Results All 4 cases showed a well-defined inhomogenous mass on CT, in which fat-like density was seen in 3 cases with focal compression of frontal bone and water-like density was found in one case with extension along frontozygomatic suture. Conclusion CT appearances of congenital dermoid cyst and epidermoid were characteristic.
