Case ReportHistory
Exam
Prior Study
1. There is a single mass lesion (consistent with low grade tumor based on history) that has undergone recent hemorrhage necrosis the blood products evident in the dorsal anterior aspect of the tumor, which has released a small amount of blood into the ventricles. There is no secondary hydrocephalus.
2. The mass causes only local mass-effects with effacement of the left frontal horn but not the left cerebral aqueduct.
3. There is age-related ex vacuo ventriculomegaly and frontotemporal atrophic changes.
Findings
T1-w MR pre contrast
There is an intraaxial, tumoral mass located in the basifrontal parenchyma extending into the anterior basal ganglia. The tumor T1 intensity is nearly isodense with the adjacent brain making differentiation of its actual margin difficult without contrast; rough estimate of the mass size is about 3-4 cm in diameter.
There is a relative small 7 x 14 x7 mm hemorrhagic component in the dorsal aspect of the tumor which lies adjacent to the left frontal horn ependymal surface, which is the likely source for the intraventricular blood. Smaller punctate microhemorrhages are also present within the rostral part of the tumor mass.
The hemorrhagic component combined with the underlying tumor causes local mass effect with nearly complete effacement of the left frontal horn.
There is known small amount of intraventricular blood in the occipital horns (evident on CT), but this is difficult to discern on T1--w MR.
Impression
2. There is some hemorrhagic necrosis in the dorsal aspect of the mass lesion accounting for the minimal intraventricular blood.
