Intracerebral Schwannoma--case report
Neurologia Medico-Chirurgica
|July 1, 1997
Summary
A rare intracerebral schwannoma, a brain tumor not originating from cranial nerves, presented as an epileptic seizure in a 15-year-old girl. This finding highlights the diverse origins and presentations of these unusual central nervous system tumors.
Area of Science:
- Neuro-oncology
- Neuropathology
- Neurosurgery
Background:
- Intracerebral schwannomas are rare tumors that do not originate from cranial nerves.
- These tumors are typically found in children and young adults.
- The origin of these tumors is often attributed to ectopic or perivascular elements within the brain.
Observation:
- A 15-year-old female presented with epileptic seizures.
- Imaging studies revealed a right parietooccipital lobe tumor.
- Preoperative diagnosis suggested malignant glioma.
Findings:
- Immunohistochemical and ultrastructural analyses confirmed the tumor was indistinguishable from peripheral schwannoma.
- Only 29 cases of non-cranial nerve-related schwannomas have been previously reported.
- Intracerebral schwannomas can be classified based on their origin: intra-axial, periventricular, dural attachment, or other types.
Implications:
- This case expands the understanding of rare intracerebral tumors.
- It underscores the importance of comprehensive histopathological examination for accurate diagnosis.
- Further research into the origins and classification of these tumors is warranted.
