Abstract
Intracranial xanthogranuloma (XG) can occur within ventricles or brain parenchyma.
Intraventricular XG radiographic features are similar to choroid plexus tumors.
Lateral ventricle XG may present with motor deficits, seizures, and visual changes.
Third ventricle XG may present with hydrocephalus and motor, cognitive deficits.
If symptomatic XG is suspected, resection may be delayed due to their benign nature.
Intracranial xanthogranulomas (XG) are a rare benign histiocytic neoplasm and most often within the choroid. The majority are asymptomatic and are found incidentally on imaging or post-mortem examination or autopsy. We present a case of symptomatic XG in a pregnant patient who underwent a delayed transcortical, transventricular approach for lateral ventricle XG resection following the completion of her pregnancy. Four years post-operatively, the patient is neurologically intact and without recurrence. Our review of the literature showed differences among XG depending on location. The clinical and radiological features of XG are often indistinguishable from tumors arising from the choroid plexus and should be considered as a rare etiology in the differential of newly diagnosed intraventricular lesions.
