This study details a rare case of intradural primary osteosarcoma (IPOS), a chondroblastic subtype, found within the brain and subarachnoid space. This marks the sixth reported IPOS case and the first of its specific subtype.

Area of Science:

  • Neuro-oncology
  • Surgical Pathology

Background:

  • Intradural primary osteosarcoma (IPOS) is an exceptionally rare primary bone tumor occurring within the central nervous system.
  • Distinguishing IPOS from dural-based or metastatic osteosarcomas is critical for accurate diagnosis and treatment planning.

Observation:

  • A 74-year-old male presented with aphasia and right hemiparesis, exhibiting a large, partially calcified left frontotemporal intracranial mass on imaging.
  • Surgical exploration revealed the tumor was exclusively intradural, infiltrating the brain parenchyma and subarachnoid space of the left sylvian fissure, with no dural involvement.

Findings:

  • Neuropathological examination confirmed the lesion as a chondroblastic osteosarcoma.
  • This represents the sixth documented instance of IPOS and the inaugural identification of the chondroblastic subtype in this location.

Implications:

  • This case expands the understanding of rare intracranial neoplasms and highlights the importance of considering IPOS in the differential diagnosis of intradural masses.
  • Further research into the pathogenesis and optimal management strategies for IPOS, particularly its subtypes, is warranted.
