Summary
Primary spinal cord melanoma is rare. This case highlights a 50-year-old female with a Th 10-11 intraparenchymatous lesion misdiagnosed as ependymoma due to imaging findings and symptom duration.
Area of Science:
- Neuropathology
- Neurosurgery
- Oncology
Background:
- Primary melanomas of the central nervous system (CNS) are exceedingly rare.
- Melanomas originating within the spinal cord parenchyma are exceptionally uncommon.
Observation:
- A 50-year-old female presented with symptoms suggestive of a spinal cord lesion.
- Magnetic Resonance Imaging (MRI) revealed an intraparenchymatous lesion at the Th 10-11 level with rounded borders and an associated intramedullary cyst.
Findings:
- The preoperative diagnosis, based on MRI and clinical presentation, was intramedullary ependymoma.
- Histopathological examination confirmed the lesion to be a primary spinal cord melanoma, not an ependymoma.
Implications:
- This case underscores the diagnostic challenges in differentiating primary spinal cord melanoma from other intramedullary tumors.
- Accurate preoperative diagnosis is crucial for appropriate surgical planning and patient management.
- Further research into the imaging characteristics and clinical presentation of rare spinal cord melanomas is warranted.
