Workup/Staging Flashcards
What are the 2 most common Sx at presentation in pts with CP tumors?
Hydrocephalus and HA (d/t CSF overproduction and flow obstruction)
What studies need to be performed during the workup for CP tumors?
MRI of brain and spine and CSF cytology
What is the differential for an intraventricular mass?
Ependymoma, subependymoma, central neurocytoma, subependymal giant cell astrocytoma, CPP, CPC, meningioma, mets. (Koeller KK et al., Radiographics 2002)
What are the radiologic features of CPPs vs. CPCs?
CPP: lobulated, solid, well-demarcated intraventricular mass that is isodense to mildly hyperdense on CT, often with calcifications. On MRI, homogeneous with intense contrast enhancement.
CPC: usually larger than papillomas with heterogeneous signal patterns on CT and MRI; may contain calcifications, necrosis, and hemorrhage and frequently invades brain parenchyma.
