Abstract
- A case of a mature, cystic teratoma in posterior cranial fossa presenting as a hyperdense lesion on precontrast computed tomography(CT) is reported. Although typical cysts of epidermoid, dermoid and teratoma appear on CT scans as areas of decreased attenuation, the cyst of this case showed increased density on precontrast CT scan. The underlying cause for this CT appearance is discussed after literature related to teratomas that are located in the midline posterior fossa are reviewed.
