Pilomyxoid astrocytoma with involvement of the sella turcica in an adolescent.
Pilomyxoid astrocytoma (PMA) is a recently described tumor typically occurring in the hypothalamic-chiasmatic region of very young children. PMA is characterized by a more aggressive course than pilocytic astrocytoma and exhibits certain differing histological features. We report a PMA in an adolescent patient with visual field disturbance. Imaging studies revealed enlargement of the sella turcica due to a homogenously enhancing sellar and suprasellar mass identifiable both on CT scans and MRI. We believe that PMA may be included in the list of differential diagnoses of the lesions expanding the sella turcica.
