Diagnosis: Malignant neoplasm of brain, unspecifiedClinical question: pre op planningSigns and Symptoms: tumor resection planning There is redemonstration of status post left-sided craniotomy for removal of a mass centered in the left inferior parietal lobule. There is T2 and FLAIR signal hyperintense lesion at the tumor bed. There is a masslike lesion measuring 18 x 15 mm axial dimensions along the posterior, medial and superior margins of the surgical site.An extra-axial lesion is present adjacent to the left temporal lobe which measures 11 mm on the current exam and 9 mm on the prior exam.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 are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.Findings raise the question of local recurrence at the left parietal surgical site.2.An extra-axial mass adjacent to the left temporal lobe is slightly larger on the current exam when compared to the prior exam.3.Examination is limited and was performed for the purpose of the treatment planning.
