Summary
The authors report three cases of intraparenchymatous neuroepithelial cysts, which did not communicate with the ventricular system and the subarachnoid space. They were located in (1) the right frontal lobe, (2) the left cerebral peduncle and pons, and (3) the right cerebellar hemisphere. All of them were asymptomatic, despite their volume and location, and presented as incidental autopsy findings. A developmental origin is likely for these non-neoplastic cysts.
