Slit ventricle syndrome

Slit ventricle syndrome is defined as the radiological appearance of slit-like ventricles on CT and MRI images in patients with ventriculoperitoneal shunt. Mild forms are seen in adults and more severe forms are seen in children. Patients must be symptomatic to be diagnosed with slit ventricle syndrome.

Clinical presentation

  • nausea
  • vomiting


The exact aetiology behind slit ventricle syndrome is debatable and include 3:

  • intermittent proximal catheter obstruction with collapsed ventricles
  • shunt obstruction resulting with increased intracranial pressure from non-compliant ventricles

Radiographic appearance

Small ventricles with a characteristic slit-like appearance. Only diagnosed if the patient is symptomatic.
