Summary
Multiple spinal schwannomas, rare tumors of the cauda equina, were identified in a patient. This case emphasizes the importance of advanced imaging for diagnosing these distinct nerve sheath tumors.
Area of Science:
- Neurosurgery
- Oncology
- Radiology
Background:
- Spinal schwannomas are the most common intradural extramedullary tumors, typically arising from a single nerve fiber.
- Multiple schwannomas affecting the cauda equina are exceptionally rare.
Observation:
- A 37-year-old female with a history of schwannoma presented with multiple space-occupying lesions in the lumbosacral canal.
- Magnetic resonance imaging revealed persistent, multiple, bead-like nodular masses within the L1-S1 segments, involving distinct nerve fibers of the cauda equina.
- Contrast-enhanced MRI showed homogenous enhancement without bleeding or cystic components.
Findings:
- Pathological examination of the resected specimen confirmed the diagnosis of schwannoma.
- The lesions were comparable in size and number to those observed two years prior, despite a pregnancy during the interim.
Implications:
- This case underscores the necessity of preoperative magnetic resonance imaging for precise tumor visualization and surgical planning.
- Accurate radiological diagnosis is crucial for effective patient management of multiple cauda equina schwannomas.
