[Neuroradiologic imaging results suggestive of parasitic cysts in central nervous system in course of neoplastic disorders--cases report].
Cystic changes within CNS, revealed by computed tomography or magnetic resonance imaging, pose difficult diagnostic and therapeutic problem. We present two patients with primary diagnosis of parasitic cysts of CNS, in whom neoplastic etiology was finally confirmed. Differential diagnosis of cystic foci should from the beginning include not only parasitic infections, but also neoplastic diseases, which are much more frequent in Poland at present and in which prolonged diagnostic process and delayed treatment is highly unfavorable.
