Summary
This study reports a rare case of an intracranial germinoma in an adult woman, presenting uniquely with amnesia and hyperphagia. The findings highlight the diverse clinical manifestations of this rare brain tumor.
Area of Science:
- Neuro-oncology
- Endocrinology
Background:
- Intracranial germinomas typically present in children with specific syndromes like Parinaud's or hypopituitarism.
- Intraparenchymal hypothalamic germinomas are exceptionally rare, primarily documented in prepubertal males with severe neurological deficits.
Observation:
- This report details an unusual case of a 24-year-old woman with an anterior hypothalamic, thalamic, and basal forebrain germinoma.
- The patient presented with hydrocephalus, progressive anterograde amnesia, and hyperphagia, despite being endocrinologically normal.
Findings:
- Stereotactic biopsy confirmed the diagnosis of germinoma in the intraaxial tumor.
- The tumor's location restricted to the anterior hypothalamus and thalamus is rarely reported.
Implications:
- This case expands the known clinical spectrum of intracranial germinomas.
- Highlights the importance of considering germinomas in adult patients with atypical neurological and endocrine presentations.
