Intradural lumbosacral malignant extrarenal rhabdoid tumor: a case report

Childs Nerv Syst. 2018 Jan;34(1):165-167. doi: 10.1007/s00381-017-3571-2. Epub 2017 Aug 16.


Background: Rhabdoid tumors are highly malignant tumors predominantly affecting the pediatric population. When these tumors occur outside of the kidneys, they are referred to as malignant extrarenal rhabdoid tumors (MERT), a rare highly aggressive subtype. Less commonly, these tumors involve the neuro-axis.

Objective: Here we present a case of a 15-year-old girl with intradural MERT of the lumbosacral spine who presented with back pain, sudden worsening of lower extremity strength, and complete loss of bowel and bladder control.

Results: The patient's tumor showed loss of INI-1 and negative staining for cytokeratin AE1AE3, CD99, and SOX10.

Conclusions: To our knowledge, there are no previous case reports of MERT with intradural lumbosacral spinal involvement.
