Concurrent schwannoma and intradural neuroma after resection of a cauda equina schwannoma. A case report and first description.
OBJECTIVE
We present the case of a 33-year-old female complaining of recurrent pain and sensory disturbance in both legs, 3 years after the removal of a schwannoma at the level of L2/3.


METHODS
Magnetic resonance imaging showed two lesions at the site of the previous operation. Assuming tumour recurrence, the patient was referred for surgery.


RESULTS
Intraoperatively, both an intradural neuroma and a schwannoma were found. Histopathological assessment confirmed the diagnosis of both coexisting entities.


CONCLUSIONS
Neuroma should be considered in the differential diagnosis of spinal lesions, particularly in the assumption of recurrence.
