BACKGROUND: Choroid plexus (CP) metastases are an extremely rare condition accounting for less than 1% of brain metastases. Due to its scarcity, little is known about this pathology and its management. Herein, we propose a review of the current literature to help its diagnosis and management.
METHODS: Through a literature review based on PubMed/MEDLINE database, we reviewed 94 cases of intraventricular metastasis of solid cancer in 28 full-text articles in English from 1980 to 2010. We have reported epidemiological, clinical, radiological, histological data, as well as management strategies and outcomes. A case report of fourth ventricular pulmonary metastasis illustrates this review.
RESULTS: Intraventricular metastases are most often reported in patients in their 6th decade. The clinical presentation is marked by acute hydrocephalus, more rarely lesional bleeding. Three-quarters of intraventricular metastases develop in lateral ventricle, then respectively in the fourth and third ventricles. Kidney cancer accounts for 45% of the cases. The treatment modalities are surgical removal in case of a single lesion and adjuvant radiotherapy and chemotherapy depending on the primary cancer. The prognosis remains poor due to dissemination via the cerebrospinal fluid.
CONCLUSION: Multiple choroid plexus metastasis is a rare diagnosis, affecting patients with a specific clinical presentation and a misleading radiological appearance. There is no standard of care for the management of these lesions and surgical approach can be challenging.
