A rare atypical pleomorphic xanthoastrocytoma caused a seizure in a 65-year-old man. Despite surgery and radiotherapy, the aggressive brain tumor regrew, leading to fatal outcomes within 22 months.

Area of Science:

  • Neuro-oncology
  • Neuroradiology
  • Neuropathology

Background:

  • Pleomorphic xanthoastrocytoma (PXA) is a rare glial tumor, typically affecting young adults.
  • Atypical variants of PXA are associated with a poorer prognosis and higher recurrence rates.

Observation:

  • A 65-year-old male presented with an ictal episode.
  • CT imaging identified a left capsulo-thalamic mass.
  • Single-photon emission computed tomography (SPET) revealed left cerebral hemisphere hypoperfusion.

Findings:

  • Subtotal tumor resection was performed, followed by adjuvant radiotherapy.
  • Pathological examination confirmed an
  • atypical" pleomorphic xanthoastrocytoma.
  • The patient experienced massive tumor regrowth, succumbing to the disease 22 months post-surgery.

Implications:

  • This case highlights the aggressive nature and poor prognosis of atypical pleomorphic xanthoastrocytomas, even in older patients.
  • The findings underscore the importance of comprehensive histopathological evaluation and consideration of aggressive treatment strategies for these rare tumors.
  • Further research into the molecular mechanisms driving atypical PXA progression is warranted to improve therapeutic outcomes.
