Summary
This study documents the first reported case of a granular cell astrocytoma within the spinal cord. This rare central nervous system tumor presents unique clinical, pathological, and radiological features.
Area of Science:
- Neuro-oncology
- Spinal Cord Pathology
- Central Nervous System (CNS) Tumors
Background:
- Granular cell astrocytomas are rare central nervous system (CNS) tumors.
- No prior cases of spinal cord granular cell astrocytomas have been documented.
- Distinguishing these from benign spinal granular cell tumors is crucial.
Observation:
- A 48-year-old female presented with a year of dorsal pain and progressive spastic paraparesis.
- MRI revealed a 2-cm contrast-enhancing intramedullary mass at T6-T7, consistent with astrocytoma.
- Surgical debulking and dissection were performed on the infiltrating tumor.
Findings:
- Histological diagnosis confirmed astrocytoma with granular cell differentiation.
- This represents the first documented case of an intramedullary granular cell astrocytoma.
- Literature review highlights differences from other spinal cord tumors with granular changes.
Implications:
- Adds a unique case to the understanding of rare CNS tumors.
- Provides a reference for clinical, pathological, and radiological diagnosis of spinal granular cell astrocytomas.
- Contributes to differentiating these from other spinal cord lesions with granular morphology.
