Giant bilateral xanthogranulomas in a child: case report

Symptomatic bilateral choroid plexus xanthogranuloma in a pediatric patient

INTRODUCTION

Central nervous system xanthogranulomas are uncommon clinical entities, and symptomatic bilateral choroid plexus xanthogranulomas are rare.

CASE PRESENTATION

We present the case of a 15-year-old male patient with bilateral choroid plexus xanthogranulomas with symptoms of increased intracranial pressure. Gross total resection of the tumor in the left lateral ventricle was performed. The patient improved, and asymptomatic right-sided tumor was monitored at follow-up.

CONCLUSION

The main treatment objective in these tumors is gross total resection. Asymptomatic tumors can be followed without intervention. However, surgery should be performed for symptomatic tumors that cause hydrocephalus or symptoms of increased intracranial pressure.

Symptomatic Bilateral Xanthogranuloma of the Choroid Plexus

Xanthogranulomas (XGRs) of the choroid plexus are rare, asymptomatic, and benign lesions usually found incidentally. Here, we present a case of a 47-year-old male with bilateral XGR of the choroid plexus with periventricular edema and discuss our case in relation to a review of existing literature pertaining to the radiology of XGRs. To the best of our knowledge, this is the first reported case of bilateral trigonal XGR causing brain edema without ventricular dilatation. Despite the fact that they can cause hydrocephalus, XGRs are silent and benign lesions. Although the etiopathology of XGRs remains poorly understood, enhanced imaging analyses may provide additional information regarding edema and focal white matter signal changes.

Xanthogranuloma of the choroid plexus of the third ventricle: case report and literature review

Xanthogranulomas of the choroids plexus (XG) are benign tumours of debatable etiology which become rarely symptomatic. Only few cases have been studied with MRI. A new case of xanthogranuloma of the third ventricle showing unusual features in the CT and MRI studies in a 47-year-old man with a 2-month history of gait and urinary disturbances and cognitive impairment is reported. The literature concerning clinical and neuroradiological presentation of intracranial xanthogranulomas is reviewed.
