Pituicytoma: case report and literature review

J Chu et al. Br J Radiol. 2011 Mar.

Abstract

Pituicytoma is a rare primary tumour of the neurohypophysis or infundibulum, which masquerades as a pituitary adenoma. We present a pituicytoma case in a 45-year-old female presenting as a focal lesion of the neurohypophysis. This case report reviews the clinical, neuroimaging and histopathological features of this rare tumour in order to understand it better.

(a) Sagittal unenhanced T1 weighted MRI showing nodular thickening of the pituitary stalk causing optic chiasmal compression (arrow). Note the absence of hyperintensity within the hypophysis. (b) Coronal T2 weighted MRI showed slight hyperintensity of the tumour compared with the brain parenchyma (arrow). (c) Sagittal contrast-enhanced T1 weighted MRI demonstrated marked enhancement of the tumour (arrow). (d) Histology with haematoxylin and eosin stain revealed the tumour to be composed of spindle-shaped cells, which are characterised by a storiform structure.
