OBJECTIVE AND IMPORTANCE: We report an unusual case of ecchordosis physaliphora of the thoracic spine. CLINICAL PRESENTATION: The clinical presentation was one of disabling thoracic radicular pain without objective neurological deficit. The imaging characteristics of the lesion were those of a cyst containing aqueous fluid. There was no bone destruction. INTERVENTION: Gross total removal of the lesion was accomplished. CONCLUSION: We present the only well-documented case of thoracic extradural ecchordosis physaliphora and discuss the relationship between the notochord, ecchordosis physaliphora, and chordoma. We provide a comprehensive list of lesions exhibiting physaliphorous cells.
