Endodermal sinus tumor of the pineal region: case report
Neurosurgery
|November 1, 1978
Summary
A rare pure endodermal sinus tumor, a type of germ cell tumor, was diagnosed in a 13-year-old boy with elevated alpha-fetoprotein. Treatment involved tumor resection and craniospinal radiation.
Area of Science:
- Neuro-oncology
- Pediatric oncology
- Pathology
Background:
- Germ cell tumors (GCTs) are rare in the central nervous system.
- Intracranial endodermal sinus tumors (ESTs) are exceptionally rare GCTs.
Observation:
- A 13-year-old male presented with symptoms indicative of a posterior third ventricle tumor.
- Elevated serum and cerebrospinal fluid alpha-fetoprotein levels were noted.
Findings:
- Histopathological examination confirmed a pure endodermal sinus tumor.
- This represents one of only 13 reported intracranial cases of ESTs.
Implications:
- Highlights the importance of considering rare GCTs in pediatric posterior fossa tumors.
- Suggests a potential role for alpha-fetoprotein as a tumor marker in such cases.
- Contributes to the limited literature on intracranial endodermal sinus tumors.
