They are most seen in the cerebellopontine angle, fourth ventricle, or parasellar regions. Patients typically become symptomatic between 20- and 40 years of age. We present a rare case of a symptomatic intrinsic brainstem epidermoid cyst in a 12-year-old girl with atypical radiological features.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description: <\/jats:title>\n<jats:p>A 12-year-old girl presented with progressive gait disturbances, disequilibrium, diplopia due to right-sided abducens paresis, left-sided facial paresis (HB grade II), headaches, nausea, and vomiting over the past 6 months. Magnetic resonance imaging (MRI) revealed an intrinsic lesion of the brainstem not present on MRI 4 years prior. A microsurgical gross total resection, including resection of cyst wall, was performed. The pathology report diagnosed the lesion as an epidermoid cyst. The patient improved significantly after resection.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>This pathology represents &lt;1% of all intracranial tumors, and with only 21 documented pediatric intrinsic brainstem cases in medical literature, very rarely has an intrinsic brainstem location. We detail the medical history, work-up, surgical management, and postoperative outcomes, contributing to the limited body of knowledge regarding this exceptional entity.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_198_2025","type":"journal-article","created":{"date-parts":[[2025,7,18]],"date-time":"2025-07-18T08:51:02Z","timestamp":1752828662000},"page":"290","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Intrinsic brainstem epidermoid cyst in childhood"],"prefix":"10.25259","volume":"16","author":[{"given":"Tybault","family":"Hollanders","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sarah","family":"Hendrickx","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edward","family":"Baert","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2025,7,18]]},"reference":[{"key":"10.25259\/SNI_198_2025\/ref-1","doi-asserted-by":"crossref","first-page":"101469","DOI":"10.1016\/j.inat.2021.101469","article-title":"Epidermoid cysts of the fourth ventricle","volume":"28","author":"Bensamma","year":"2022","journal-title":"Interdisciplin Neurosurg"},{"key":"10.25259\/SNI_198_2025\/ref-2","doi-asserted-by":"crossref","first-page":"145","DOI":"10.1111\/j.1552-6569.2011.00608.x","article-title":"Epidermoid cyst with a metabolite pattern mimicking a brain abscess.
