RESUMO
Ectopic recurrence of craniopharyngioma is extremely rare following transcranial procedures of primary tumour. Here we describe 3 new cases of ectopic recurrence along the surgical route after transcranial gross total resection of primary tumour. All 3 cases are male adults--2 of them had papillary-type tumour with the other being adamantinomatous. All ectopic tumours were safely resected via repeated craniotomy. Long-term surveillance of patients with resected craniopharyngioma is essential.

Ectopic recurrence of craniopharyngioma is extremely rare. Two mechanisms have been proposed to explain this phenomenon: direct implantation along the previous surgical tract and dissemination via cerebrospinal fluid (CSF). We present a case of ectopic recurrence along the surgical route after transcranial gross total resection (GTR) of primary tumor. Cystic tumor seems to be a risk factor of ectopic recurrence and one must be extra careful when manipulating such tumors. We emphasize GTR and the importance of complete aspiration of cystic fluid before resecting the capsule to avoid rupture or spillage. Long-term clinical and radiological follow-up is recommended as ectopic recurrence may occur extremely late.
