Diagnosis: Neoplasm of uncertain behavior of brain, unspecified. Unspecified convulsionsClinical question: Eval for growth of low grade glioma. No prior RT.Signs and Symptoms: low grade glioma.Comments: Low grade glioma. S/p surgery in 2008. | There is redemonstration of a 17 x 36 mm axial dimension extra-axial cyst adjacent to the left inferior and middle frontal gyri as well as the left temporal pole. There is associated calvarial scalloping present.There is redemonstration of cystic encephalomalacia of the right temporal lobe anteriorly associated with 26 x 35 mm cyst. This has not changed since the prior exam. There is signal change present along the right temporal lobe adjacent to the cyst. This likely represents gliosis. The patient is status post right-sided craniotomy for removal of a right temporal lobe mass.There is redemonstration of a small T2 and FLAIR hyperintense lesion the left thalamus. This is stable compared to prior examsNo abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.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 demonstrate mucous retention cyst in the right maxillary sinus as well as mucosal thickening in the ethmoid air cells, frontal sinuses sphenoid sinuses and left maxillary sinus. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.No evidence for tumor recurrence in the right temporal lobe.2.Left-sided arachnoid cyst this is stable3.Stable lesion in the left thalamus
