CT before and after contrast showing posterior fossa mass with total enhancement
Note total homogenous enhancement
Not dilated ventricles denoting obstructive hydrocephalus
Heterogeneous enhancement
With calcification
ependymoma
Appears as hyperdense lesion in CT without contrast surrounded by hypodense edema with positive mass effect
Appears in CT with contrast as a hypodense lesion with enhancement in the wall surrounded by hypodense edema and may cause positive mass effect
Appears in CT with contrast as a mass with heterogenous enhancement surrounded by hypodense edema with positive mass effect
Appears in CT with contrast as brain tumor, but being multiple suggest metastasis
Depressed fracture of the left parietal bone
