Summary
A 16-year-old female with a positive pregnancy test and neurological symptoms was diagnosed with a rare hypothalamic mixed germ cell tumor. This case highlights the importance of considering complex diagnoses in adolescents.
Area of Science:
- Pediatric Endocrinology
- Neuro-oncology
- Reproductive Medicine
Background:
- Adolescent presentation with nausea, vomiting, dehydration, weakness, and tremor.
- Initial suspicion of pregnancy due to positive beta-human chorionic gonadotropin (β-hCG) test.
- Co-existing primary amenorrhea and delayed growth suggested underlying endocrine or developmental issues.
Purpose of the Study:
- To investigate the cause of neurological and endocrine symptoms in a 16-year-old female.
- To evaluate the diagnostic pathway for a rare suprasellar/hypothalamic tumor.
- To determine the nature and management of a mixed germ cell tumor in an adolescent.
Main Methods:
- Clinical presentation and history assessment.
- Laboratory tests including urine for β-hCG.
- Pelvic ultrasound, Head CT scan, and MRI of the brain.
- Surgical resection and histopathological examination of the tumor.
Main Results:
- Pelvic ultrasound ruled out intrauterine and ectopic pregnancy.
- Imaging revealed a suprasellar tumor, further characterized as a hypothalamic tumor on MRI.
- Pathology confirmed a mixed germ cell tumor with no evidence of metastasis.
Conclusions:
- A hypothalamic mixed germ cell tumor can present with symptoms mimicking pregnancy and neurological compromise.
- Comprehensive diagnostic work-up including advanced imaging is crucial for rare tumors in adolescents.
- Surgical resection is a key management strategy for localized germ cell tumors.
