Primary spinal atypical teratoid/rhabdoid tumour presenting with hematomyelia and subarachnoid haemorrhage-a case report.

Atypical teratoid/rhabdoid tumours (AT/RTs) are highly aggressive and uncommon malignant tumours of the central nervous system (CNS) affecting children younger than 3 years of age. Primary spinal cord involvement is an extremely rare presentation. AT/RTs show necrosis and haemorrhages on histopathology frequently. However, spinal atypical teratoid/rhabdoid tumour (AT/RT) with hematomyelia and spinal subarachnoid haemorrhage (SAH), as seen in our case, has never been reported in the literature in the paediatric age group. We report a case of primary spinal AT/RT in a 3-year-old male child presenting acutely with hematomyelia and spinal SAH and try to elucidate its pathophysiological basis.
