Serum sodium disorder as a long-term complication after surgery for chordoid glioma of the third ventricle: A case report and literature review
Abstract
Background: Chordoid glioma of the third ventricle is a rare tumor. Because of its special growth site and unique histomorphological characteristics, the clinical symptoms, imaging manifestations, operative difficulty, and postoperative complications may differ from those of other intracranial tumors. A review of the literature revealed limited information on the postoperative course of chordoid glioma of the third ventricle. Case presentation: A 51-year-old man presented with a 3 month history of recurrent headache. Magnetic resonance imagining showed a 2.4 × 2.2 × 2.3 cm lesion within the third ventricle causing obstruction of CSF flow at the level of the interventricular foramen of Monro with dilation of left lateral ventricle more than the right. A right frontal craniotomy was performed, with a frontal trancortical transventricular approach and gross tumor resection was done. The pathology report revealed a chordoid glioma. Two months after discharge, the patient developed an electrolyte disorder that mainly manifested as an unstable serum sodium concentration, and he was hospitalized again. Symptoms of severe hyponatremia occurred during treatment, and the patient was admitted to the intensive care unit. He recovered well with active treatment. Conclusions: Here, the post-operative complications of chordoid glioma with third ventricle should be emphasized. The authors reported continuously serum sodium disorder that might be monitored and avoided after surgery.
