Spinal schwannomas are benign nerve sheath tumors commonly arising from dorsal sensory roots and representing approximately 25–30% of intradural extramedullary spinal tumors [1]. Giant schwannomas with extensive cystic degeneration are uncommon and may mimic other cystic spinal lesions. We report a case of a giant dorsal schwannoma demonstrating marked cystic transformation on MRI. Imaging showed a well-defined intradural extramedullary lesion extending over multiple vertebral levels with heterogeneous signal intensity and large intralesional cystic components. Recognition of these imaging features is essential for accurate diagnosis and surgical planning [2].
