Isolated cerebellopontine angle craniopharyngioma

Isolated petrous apex ectopic craniopharyngioma

“…7 The post-operative occurrence of ectopic craniopharyngiomas by direct mechanical transplantation or meningeal seeding is a recognized phenomenon. 3,8 Nevertheless, histologically confirmed primary craniopharyngioma at an ectopic location is rare, although cases of epidural, 5 frontotemporal, 8 posterior fossa, 2,6,9 and infrasellar craniopharyngiomas 1,4,10,11 have been reported. On the other hand, primary isolated petrous apex craniopharyngioma has not been previously reported.…”

“…Generally, the symptoms could consist of visual, endocrine, or cognitive disturbance, and all the symptoms related with high intracranial pressure. [1][2][3][4][5][6][7][8][9][10][11] In this case, the symptom was only double vision with esotropia (in-turning eye) on examination. We believed that it was caused by compression on the sixth nerve by tumor protrusion to the prepontine cistern and the direct compression to the Dorello's canal.…”

“…1,4,6 CT scans play an important role in identifying bony anatomy and calcifications. MRI will show tumor extension and its consistency, both solid or cystic part, enhanced scanning range and the relationship to adjacent neurovascular structures.…”

“…[1][2][3][4][5] Isolated infrasellar craniopharyngiomas without sellar involvement are extremely rare. 4,6 Isolated craniopharyngioma in the petrous bone has never been reported. This study reports an extremely rare case; histologically confirmed primary ectopic craniopharyngioma that arose at the apex of right petrous bone.…”

Isolated primary craniopharyngioma in the cerebellopontine angle

“…1,2,5 Two clinicopathological variants of craniopharyngiomas have been identified. [8][9][10][11] The adult type (papillary squamous type), which largely occurs in adults and mainly consists of mature stratified squamous cells, may be of metaplastic origin and has a better prognosis. The childhood type (classical adamantinomatous variant), which occurs in patients of all ages and contains palisading columnar cells that resemble the ameloblast of fetal tooth buds, may be of embryonic origin.…”
