To perform a review of the basic aspects of demographic and clinical data and imaging findings of main intraventricular masses.
To describe the main radiological characteristics of intraventricular masses.
To provide to interested people with the necessary foundations for differential diagnosis of intraventricular masses.
The ventricular system consists of cavities (ventricles) communicated with each other,
which are covered by the ependymous and contain CSF.
The CSF is formed in choroid plexus that consist of an invagination of neuroectoderm and pia mater into the laterals,
third and fourth ventricles and it is reabsorbed into intravascular system by arachnoid villi.
Any of these structures can harbor different intraventricular pathologies or invade the ventricle.
Despite the low incidence of intraventricular masses,
they constitute a diagnostic challenge for the radiologist.
Findings and procedure details
There is a great variety of intraventricular masses.
In this review,
we will classify them as tumoral (primary and secondary tumors) and non-tumoral masses (Fig.
These lesions may be discovered as an incidental finding or for symptomps.
The symptoms that are present in these pathologies are very diverse and non-specific; they depend on the type,
location and age of the patient.
they can present irritability,
loss of appetite and psychomotor retardation; while in older children and adults cause headache,
Intraventricular masses constitute a diagnostic challenge for the radiologist. Neuroimaging findings,
demographic and clinical characteristics,
are key to perform a proper differential diagnosis in this pathology.
