Intradiploic epidermoid cyst in a 15-year-old female: a rare case report

Introduction and importance:Intradiploic epidermoid cysts are rare, benign, slow-growing lesions that originate from the inclusion of ectodermal elements during the closure of the neural tube. This article reports a case of a rare, benign intradiploic epidermoid cyst.Case presentation:A 15-year-old female patient had a cystic swelling located in the occipital region, caused the patient to experience a progressively enlarging swelling and intense headaches. It was diagnosed as intradiploic epidermoid cyst on MRI. Surgery was done and removed. Postoperative outcomes were very good.Clinical discussion:Intradiploic epidermoid cysts are quite rare. Although these cysts usually happen because of this ectoderm inclusion, the patient's history of falling raises questions about whether trauma could have caused it too. We really need more research to see if there's a connection between injuries & these types of cysts.Conclusion:The importance of prompt diagnosis and appropriate surgical intervention is necessary while highlighting the rarity of these lesions and their potential traumatic origin.
