In cases of hyponatremia induced by brain damage, it is important to distinguish between the syndrome of inappropriate anti-diuretic hormone secretion (SIADH) and cerebral salt wasting syndrome. A ventriculoperitoneal (VP) shunt is the standard treatment for hydrocephalus, and external lumbar drainage (ELD) is an option to evaluate the effect of a VP shunt. However, ELD has potential complications, such as subarachnoid hemorrhage, meningitis, and rarely hyponatremia. Therefore, we report a case of a patient with cerebral salt-wasting syndrome resulting from ELD to treat normal-pressure hydrocephalus during the rehabilitation of acute ischemic stroke.

Tectal glioma is an indolent and benign tumor that occurs predominantly in the pediatric population. It arises in the tectum of the midbrain and, due to its location, contributes to the development of obstructive hydrocephalus, typically presenting with increased intracranial pressure (IICP) symptoms or signs. Here we report a rare case of tectal glioma that presented as adult-onset epileptic seizures without IICP symptoms and was treated with endoscopic third ventriculostomy and antiepileptic drugs.
