ABSTRACT
Objective To analyse MRI findings of multicentric craniopharyngioma and improve knowledge to it. Methods MRI and Gd-DTPA enhanced SE T 1WI scaning were performed in 4 cases of multicentric craniopharyngioma proved by surgery and pathology before operation, PDWI scaning were performed in 2 cases.Results MRI manifestations of multicentric Craniopharyngioma is the tumors of Parenchymal -predominant mixed in the sella turcica region or Suprasellar region as the center focus in 4 cases, and different cystic focus were also found in the di-temporal lobe,the basis of anterior cranium fossa,the anterior part of third ventricle,the pontine cistern, the caudate nucleus.Cystic-Parenchymal focus has low-iso mixed signal on T 1WI and high-low mixed signal on T 2WI;cystic focus of the tumors had different signal,signal ranges form low up to high on T 1WI,while high signal on T 2WI and from iso-signal to high on PDWI. After Gd-DTPA enhanced,annular wall enhancement were seen on cystic focus,Parenchymal focus appeared as uniform enhancement.Conclusion The multicentric craniopharyngioma growth performance is multi-origination growth with the sella turcica region or suprasellar region center, the MRI signal specialty of craniopharyngioma is related to ratio of cystic-consolidated and the contents of the cystic fluid.
