Paraganglioma of the cauda equina: a case presenting features of increased intracranial pressure

Paragangliomas are benign tumors arising from the heterotopic sympathetic ganglion. They occur more often in the carotid body, glomus jugulare, mediastinum, and paraaortic region; central nervous system locations include the petrous ridge, pineal region, and sella turcica. We report the clinical and imaging features of an unusual case of paraganglioma of the cauda equina. Magnetic resonance imaging (MRI) of the thoracolumbar region should be performed in cases of increased intracranial pressure whenever the head examination does not reveal the exact cause of the problem.
