Learning objectives
To describe and show the basic anatomy of the cerebral ventricles.
To list and illustrate the most important imaging features of common cerebral intraventricular tumors.
To analyze the differential diagnosis of these lesions.
Background
There is a wide variety of intraventricular tumors, and in many cases, they can be asymptomatic. They can be discovered as casual findings, or they can present with different symptoms depending on the location and size.
Findings and procedure details
It is essential to know the ventricles basic anatomy to understand the different entities that can occur in the cerebral ventricles and understand the symptoms that cause these neoplasms.
The imaging findings of different intraventricular neoplasms types can be similar. Therefore, it is crucial to know not only the main CT or MRI imaging findings but also, location of these neoplasms and patient’s age and gender, to narrow the differential diagnosis.
Presenting symptoms depend on the location: the lesions that occur in the fourth ventricle...
Conclusion
There are different types of tumors located in the ventricles, so a radiologist must know the main imaging features, along with the patient's clinic, age, and gender, to limit the differential diagnosis.
