Abstract

Background: Choroid plexus papillomas (CPPs) are benign slow-growing tumors with the most common site as the choroid plexus of the lateral ventricle in children. These are highly vascular solid tumors which have classical diagnosis in contrast-enhanced computerized tomography (CECT) and contrast-enhanced magnetic resonance imaging (CEMRI). These require early management because of their secondary symptoms related to hydrocephalus and others due to tumoral compression. Case Report: We present a 10-month-old male child with abnormal eye movements and fever following head trauma seventeen days before. Ultrasound of the brain revealed the hyperechoic mass in the right lateral ventricle. CECT and CEMRI diagnosed as a case of choroid plexus papilloma with gross hydrocephalus. This was a silent CPP which came to limelight following head trauma. Ventriculoperitoneal shunt was placed for the decompression of the ventricular system and was advised for subsequent surgical management. Conclusion: Atypical presentations of CPP can confuse in making the diagnosis and this delay can be harmful to the patient. Early diagnosis of CPP is very important as these are slow-growing tumors which can lead to various complications if late diagnosis is made. Cross-sectional modalities such as CECT and CEMRI are the most valuable diagnostic modality tools for the early diagnosis

Highlights

Choroid plexus papillomas (CPPs) are of the neuroepithelial origin and arise from choroid plexus
The site of lateral ventricle is more common in children as compared to fourth ventricle in adults
CPP arises from choroid epithelium and these are very slow-growing tumors and may be diagnosed quite late as happened in our present case

Summary

Introduction

Choroid plexus papillomas (CPPs) are of the neuroepithelial origin and arise from choroid plexus. These constitute 3% of all intracranial tumors of the children[1]. The most common site is ventricular system. The site of lateral ventricle is more common in children as compared to fourth ventricle in adults. Other rare sites are from third ventricle and cerebellopontine angle[2]. There are cases where the intraparenchymal location of CPP has been described
