However, as knowledge of these tests becomes more widespread, these types of tumours will be more accurately diagnosed.</p><h2>What is staging?</h2><p>Staging determines the extent of treatment that is needed, which depends on the child’s age and factors related to the tumour. Rhabdoid tumours are currently staged, or divided into two groups, called “localized” or “metastatic.”</p><p>These stages are based on the collected results of previous treatments of children at hospitals around the world.</p><p>A rhabdoid tumour is called localized if the tumour cells have not spread to other parts of the brain or into the cerebrospinal fluid (CSF). This is seen from a lumbar puncture and MRI scan. A rhabdoid tumour is called metastatic if the tumour cells have spread to other parts of the brain or into the cerebrospinal fluid (CSF).</p><p>To stage the tumour, the following diagnostic tools are used: computerized tomography (CT) scans, magnetic resonance imaging (MRI) of the brain and spine, and lumbar puncture.</p><h2>More information</h2><ul><li> <a href="/Article?contentid=1315&language=English">Rhabdoid Tumours</a></li><li> <a href="/Article?contentid=1347&language=English">Treatment of Rhabdoid Tumours</a><br></li><li> <a href="/Article?contentid=1347&language=English">Recurrence of Rhabdoid Tumours</a><br></li></ul> <br>Diagnosis of rhabdoid tumours
