Spinal paraganglioma presenting as normal pressure hydrocephalus: a rare occurrence.

Objective: We report a 63 years old female who presented with confusion, urinary retention and gait disturbances. Method: CT head shows communicating hydrocephalus. Spinal MRI demonstrated an L5- S1 intradural lesion. Result: Histopathology proved it to be paraganglioma. Postoperative CT head showed reduction in size of ventricles. Association between spinal tumors and hydrocephalus is known but occurs infrequently. Conclusion: The presence of an intraspinal tumor must be kept in mind as a possible cause of the hydrocephalus.
