Summary
Rare pineal region tumours, often germinomas, present diagnostic challenges. Magnetic resonance imaging is crucial for identifying mass characteristics and guiding treatment for these rare neoplasms.
Area of Science:
- Neuro-oncology
- Radiology
- Neurosurgery
Background:
- Pineal region tumours are rare, accounting for 0.3-2.7% of intracranial neoplasms.
- Germ cell tumours, particularly germinoma, are the most frequent type.
- Simultaneous involvement of the pineal gland, suprasellar region, and fourth ventricle is uncommon.
Observation:
- A 20-year-old male presented with visual disturbances and panhypopituitarism.
- Magnetic resonance imaging revealed two enhancing masses: one in the pineal region (grey matter signal) and another in the hypothalamus (heterogeneous, cystic).
- Dissemination was noted with ependymal enhancement in the frontal horns and fourth ventricle.
Findings:
- Magnetic resonance imaging is pivotal for diagnosing pineal region masses.
- Key imaging features include mass origin, heterogeneity, contrast enhancement, fat/calcium presence, grey matter signal, and subarachnoid dissemination.
- Integrating imaging findings with patient demographics (age, sex) and tumour markers aids diagnosis.
Implications:
- Accurate diagnosis of pineal region tumours relies heavily on detailed MRI analysis.
- Understanding imaging characteristics is essential for effective treatment planning.
- This case highlights the importance of comprehensive evaluation for rare central nervous system neoplasms.
