A recurrent craniopharyngioma presented as a frontal lobe mass 8 years after initial surgery. This ectopic tumor likely arose from tumor cell seeding during the first operation.

Area of Science:

  • Neurosurgery
  • Oncology
  • Pathology

Background:

  • Craniopharyngiomas are rare tumors typically arising in the sellar region.
  • Surgical resection is a primary treatment modality for craniopharyngiomas.

Observation:

  • A 66-year-old woman developed a new, asymptomatic right frontal lobe mass 5 years post-craniotomy for craniopharyngioma removal.
  • The mass enlarged over 3 years, becoming multiloculated and partially cystic.

Findings:

  • A repeat craniotomy revealed the mass to be an ectopic craniopharyngioma.
  • The tumor's location suggested seeding of neoplastic cells along the surgical tract from the initial procedure.

Implications:

  • This case highlights the potential for distant recurrence of craniopharyngioma via iatrogenic seeding.

  • Awareness of this rare complication is crucial for long-term patient surveillance after craniopharyngioma surgery.
  • Minimizing tumor cell dissemination during surgery may reduce the risk of ectopic recurrence.
