Summary

Ruptured intracranial dermoid cysts can spill fatty material into the cerebrospinal fluid, causing complications. This case highlights imaging findings and long-term follow-up after incomplete resection of a ruptured dermoid cyst.

Area of Science:

  • Neurology
  • Neurosurgery
  • Radiology

Background:

  • Intradural dermoid cysts are rare congenital intracranial tumors, accounting for ~0.05% of all intracranial lesions.
  • These benign tumors typically exhibit characteristic appearances on CT and MR imaging due to their lipid content.

Observation:

  • This report details a rare case of a ruptured dermoid cyst.
  • The rupture led to the spillage of fatty material into the cerebrospinal fluid (CSF).
  • Imaging revealed characteristic fat/fluid levels within the ventricles and fatty material in the subarachnoid space.

Findings:

  • CT and MR imaging demonstrated the characteristic fat/fluid levels and subarachnoid dissemination of fatty material.
  • The study presents a four-year follow-up after an incomplete tumor resection.

Implications:

  • Understanding the imaging characteristics of ruptured dermoid cysts is crucial for diagnosis and management.
  • This case underscores the importance of long-term monitoring following incomplete resection of such lesions.
  • The findings contribute to the literature on complications associated with intracranial dermoid cysts.
