Rationale: Hyponatremia occurs frequently in the hospital setting and may be attributable to a host of etiologies. Drugs are frequently implicated.

Spinal Intramedullary Tuberculosis with Concurrent Supra- and Infratentorial Intracranial Disease in a 9-Month-Old Boy: Case Report and Comprehensive Review of the Literature.
