Dumbbell-shaped Dermoid Cyst Extending to Temporal Fossa from Zygomatico-frontal Suture Defect

Background: Dermoid cysts are the most common orbital tumors in infants and children. They are most commonly localized in the zygomatico-frontal suture line in the periorbital region. There is a tunnel or canal in the bone wall around 1/3 of the cases. Case Presentation: In this article, a case with dermoid cyst localized in the zygomatico-frontal suture line is presented with CT and MRI findings. Conclusion: Although their diagnosis and therapy are straightforward, it should be remembered that their clinical signs will be diversified and their surgical treatment complicated due to compressive effects of the deep component. CT and MRI are effective tools for diagnosis of these lesions and the determination of their extent.
