Area of Science:

  • Pediatric Oncology
  • Neuropathology
  • Radiology

Background:

  • Primary cranial chloroma (granulocytic sarcoma) is an extremely rare extramedullary manifestation of myeloid leukemia.
  • Diagnosis is challenging due to its rarity and potential to mimic other intracranial masses.

Observation:

  • A 2-year-old boy presented with progressive bilateral exophthalmos, abducens palsy, and papilledema.
  • Imaging revealed a partially calcified mass in the sphenoid bone extending into the orbit.
  • Surgical debulking was performed, with pathology confirming granulocytic sarcoma.

Findings:

  • The patient received chemotherapy and local cranial irradiation (24 Gy).
  • Complete remission was achieved and maintained for 37 months.
  • Partial visual recovery and significant tumor size reduction were observed on follow-up MRI.

Implications:

  • This case underscores the diagnostic difficulties of primary intracranial granulocytic sarcoma.
  • Chemotherapy is crucial for achieving remission and stabilization, while surgery can address neurological deficits.
  • Early diagnosis and multimodal treatment are vital for favorable outcomes in pediatric cases.
