Differential diagnosis of spontaneously hyperdense (non-hemorrhagic) brain lesions on CT. Description of characteristics and radiological evolution,
focusing on cortical astrocytomas due to its high aggressive potential.
Solid brain lesions are more frequently hypodense,
with a lower percentage of spontaneous hyperdensity,
which gives this behavior a special value at the time of diagnosis. The differential diagnosis of focal lesions of moderate-high density is narrow and relatively affordable by combining CT and MRI. This mainly includes cavernoma,
lymphoma and primary glial tumors highly cellular and,
of high degree of malignancy. We will emphasize that type of glial tumors...

DIFFERENTIAL DIAGNOSIS LYMPHOMA HIGH GRADE ASTROCYTOMS CAVERNOMA METASTASIS We will focus on the particular characteristics and,
on the differences of lymphoma,
cavernoma and metastasis,
with respect to the AAG. HIGH GRADE ASTROCYTOMS Tumors of glial strain and poor prognosis,
with high growth rates in a short period of time.
In our experience we are dealing with grade III astrocytomas if they are biopsied soon,
and they usually show histological...
Spontaneously hyperdense brain lesions on CT comprise a short series of pathologies whose differential diagnosis is crucial since it determines the patient's management and prognosis,
especially in the case of initial astrocytomas with a high degree of malignancy. The knowledge of the characteristics on CT and MRI of these entities allows access to a correct presurgical diagnosis in most of the occasions.
