She presented with headache and vomiting, and imaging suggested rupture of a recurrent lesion with cerebrospinal fluid (CSF) dissemination. Emergency microsurgical resection assisted by neuroendoscopy was performed. Six months postoperatively, she developed delayed obstructive hydrocephalus, requiring neuroendoscopic fenestration and lesion debridement. A narrative literature review of ruptured intracranial dermoid cysts (IDCs) was performed, with emphasis on lesions, dissemination patterns, hydrocephalus, treatment, and reported outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>During the initial emergency surgery, the cyst exhibited paste-like consistency with a thickened capsule. Postoperative pathology confirmed a dermoid cyst. However, disseminated foci remained within the cerebral sulci and ventricles. The second surgery revealed multiple pearl-like lesions within the ventricular system with associated lipid leakage. Following clearance of these lesions, the hydrocephalus resolved.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Spontaneous rupture of a recurrent IDC is exceptional and may be followed by extensive ventricular dissemination and delayed hydrocephalus.
