Diagnosis: WeaknessClinical question: brain tumorSigns and Symptoms: weakness There is a hemorrhagic mass present centered in the right postcentral gyrus associated with surrounding vasogenic edema. On T2 imaging it measures approximately 38 x 37 mm in axial dimensions on the current exam and on the prior exam it measured 38 x 36 mm axial dimensions on the August exam the lesion was different in appearance than that there was not a thick capsule surrounding the more central hemorrhagic component. The more central hemorrhagic component measures 18 x 18 mm on the current exam and on the prior exam measured similar dimensions. The enhancement pattern of this lesion of this lesion has changed over time. Surrounding vasogenic edema has regressed since prior exams.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrates some mucosal thickening in the left maxillary sinus. The visualized portions of the mastoid air cells demonstrate scattered opacities. The visualized portions of the orbits are intact.
There is a hemorrhagic lesion present in the right parietal lobe. Changing MR appearance may be attributed to evolution of blood products within the lesion as well as adjacent reaction. Differential considerations include vascular metastasis as well as other entities such as an infectious process.
