Post-cervical laminectomy myelopathy can result from soft tissue invagination leading to cord compression as a rare complication. This case report highlights the early diagnosis and management strategies for this complication, emphasizing the role of dynamic MRI and surgical intervention. A 62-year-old male, previously operated elsewhere for cervical spondylotic myelopathy, presented with deteriorating neurology post-surgery. Initial improvement was followed by progressive worsening of symptoms. Diagnostic workup included repeat MRI, which revealed T2 signal changes in the cord but no compression in a neutral position. Dynamic MRI demonstrated cord compression due to soft tissue invagination during cervical spine extension. The patient underwent posterior cervical fusion with excision of the previous laminectomy scar, decompression confirmed with intraoperative ultrasonography, and reconstruction of paraspinal muscles to their anatomical position using crosslinks. A stepwise approach to diagnosing and managing post-cervical laminectomy cord compression due to soft tissue invagination was developed. Dynamic MRI was crucial for accurate diagnosis, while intraoperative ultrasonography ensured adequate decompression. Post-surgery, the patient showed improvement in paresthesia and upper motor neuron signs. Follow-up dynamic MRI confirmed the resolution of cord compression. Early diagnosis using dynamic MRI and repeat exploration with proper soft tissue reconstruction and spinal fusion can prevent permanent disability in patients with post-cervical laminectomy complications. Adequate attention to paraspinal tissue closure during the primary surgery is crucial to minimize the risk of subsequent complications.
