Summary

Ruptured intracranial dermoid cysts present with varied symptoms, most commonly headache in younger patients and seizures in older individuals. These rare congenital tumors can cause neurological deficits, but survival is possible.

Background:

Intracranial dermoid cysts are rare congenital neoplasms arising from ectopic cell rests.
Rupture of these cysts, though rare, can occur spontaneously and is not always fatal.
Symptoms of cyst rupture range from asymptomatic to sudden death.

Observation:

A review of published cases and an additional case of ruptured intracranial dermoid cysts was conducted.
Analysis focused on patient age profiles and clinical presentations following cyst rupture.
Common symptoms observed include headache, seizures, and hemisyndrome.

Findings:

Headache was the most frequent sign (31.8%), predominantly in younger patients (mean age 23.5 years).
Seizures were also common (29.5%), occurring more frequently in older patients (mean age 42.8 years).

Sensory or motor hemisyndrome (15.9%) and chemical meningitis (6.9%) were less common findings.

Implications:

Understanding age-related symptom presentation aids in diagnosing ruptured intracranial dermoid cysts.
Recognizing the varied clinical spectrum is crucial for timely intervention and management.
This research highlights that ruptured intracranial dermoid cysts can have non-fatal outcomes with appropriate care.
