| Discussion | Olfactory neuroblastoma 1) Introduction -Also called esthesioneuroblastoma -Rare malignant neuroectodermal tumor that arises from the superior nasal cavity -Tumor of neural crest origin that probably arise from basal cells of the olfactory epithelium 2) Primary sellar neuroblastoma mimicking pituitary adenoma -Extremely rare, origin remains unclear -Tumors arise from the ganglion of Locy which grows between the olfactory fossa and the telencephalic vesicle -Neuronal transformation from pituitary epithelium -Dupuy et al. reviewed 9 patients with primary sellar neuroblastomas; primarily in women, mean age of 40 years, 98%, bilateral hemianopsia, 66%, hyperprolactinemia, 3) Imaging findings: -A sellar mass with or without supra- or parasellar extension -Variable signal intensities on T1- and T2 WI with inconsistent enhancement patterns -Mimicking non-secretory pituitary adenoma, tuberculum sellae / diaphragma sellae meningioma facing a clinicopathological entity of “pituitary neuroblastoma.” |
